Description

[Technical Field]

[0001] The subject matter described herein relates to intraluminal physiological sensing devices (e.g., intravascular pressure-sensing and / or flow-sensing guidewires). For example, the intraluminal device may include magnetic alignment of the proximal end of the sensing guidewire within a connector. [Background technology]

[0002] Intraluminal physiological sensing devices may be introduced into a patient's body lumen and may, for example, include a physiological sensor at the distal end of a catheter or guidewire. Small diameter medical devices such as intraluminal (e.g., intravascular) catheters and guidewires may incorporate sensors (e.g., pressure, temperature, flow, or imaging sensors) whose power and communication is achieved through multifilar (e.g., bifilar, trifilar, etc.) conductor bundles or flat metal ribbons. Electrical wires may be used to couple such sensors at the distal end of the catheter or guidewire with connectors at the proximal end of the catheter or guidewire. For such catheters and guidewires, electrical contact segments are typically located in the proximal portion of the guidewire.

[0003] The information contained in this Background section of the specification, including any references cited herein and any description or discussion thereof, is included for technical reference purposes only and should not be considered as subject matter by which the scope of the present disclosure should be limited.

In some aspects, the additional magnet is positioned proximate to the guidewire electrical contact. In some aspects, the additional magnet is aligned with the guidewire electrical contact. In some aspects, the additional magnet is offset from the guidewire electrical contact.

DETAILED DESCRIPTION OF THE INVENTION

[0013] An intraluminal device is disclosed that advantageously utilizes magnetic alignment to properly position the proximal end of a sensing guidewire within a connector. One or more magnets are positioned at strategic locations within the connector and / or the connection portion of the flexible elongate member of the sensing guidewire. The strategic location of the magnets pulls the flexible elongate member down into the recess of the connector, positioning the flexible elongate member so that the locking section is aligned within the slot and the conductive portion is longitudinally aligned with the split open comb electrical contacts of the connector. Performing the alignment utilizes such strategically placed magnets to provide for correct use of the locking core mechanism within the connector, thus reducing the risk of misconnection and damage to the proximal end of the flexible elongate member.

[0014] These descriptions are provided for illustrative purposes only and should not be deemed to limit the scope of the present disclosure. Certain features may be added, removed, or modified without departing from the spirit of the claimed subject matter.

[0015] For purposes of promoting an understanding of the principles of the present disclosure, reference will now be made to the embodiments illustrated in the drawings, and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the present disclosure is intended. Any changes and further modifications to the described apparatus, systems, and methods, and any further applications of the principles of the present disclosure, as would normally occur to one skilled in the art to which the present disclosure pertains, are fully contemplated and included within the present disclosure. In particular, it is fully contemplated that features, components, and / or steps described with respect to one embodiment may be combined with features, components, and / or steps described with respect to other embodiments of the present disclosure. However, for the sake of brevity, multiple iterations of these combinations will not be separately described.

[0016] As used herein, a "flexible elongate member" or "elongate flexible member" includes at least any thin, long, flexible structure that can be inserted into a patient's vasculature. While the illustrated embodiments of the "flexible elongate member" of the present disclosure have a cylindrical profile with a circular cross-sectional profile that defines the outer diameter of the flexible elongate member, in other examples, all or a portion of the flexible elongate member may have other geometric cross-sectional profiles (e.g., oval, rectangular, square, elliptical, etc.) or non-geometric cross-sectional profiles. Flexible elongate members include, for example, intravascular catheters and intravascular guidewires. In that regard, intravascular catheters may or may not include a lumen extending along their length for receiving and / or guiding other instruments. If an intravascular catheter includes a lumen, the lumen may be centered or offset relative to the cross-sectional profile of the device.

[0017] In most embodiments, the flexible elongate member of the present disclosure includes one or more electronic, optical, or electro-optical components. For example, without limitation, the flexible elongate member may include one or more of the following types of components: pressure sensors, flow sensors, temperature sensors, imaging elements, optical fibers, ultrasound transducers, reflectors, mirrors, prisms, ablation elements, radio frequency (RF) electrodes, conductors, and / or combinations thereof. Generally, these components are configured to acquire data regarding a blood vessel or other portion of the anatomy in which the flexible elongate member is disposed. Often, the components are also configured to communicate data to an external device for processing and / or display. In some aspects, embodiments of the present disclosure include imaging devices for imaging within the lumen of a blood vessel, including both medical and non-medical applications. However, some embodiments of the present disclosure are particularly suited for use in connection with the human vasculature. Imaging of intravascular spaces, particularly the inner walls of the human vasculature, can be achieved by many different techniques, including ultrasound (often referred to as intravascular ultrasound ("IVUS") and intracardiac echocardiography ("ICE")) and optical coherence tomography ("OCT"). In other examples, infrared, thermal, or other imaging modalities are utilized. Additionally, in some examples, the flexible elongate member includes multiple electronic, optical, and / or electro-optical components (e.g., pressure sensors, temperature sensors, imaging elements, optical fibers, ultrasound transducers, reflectors, mirrors, prisms, ablation elements, RF electrodes, conductors, etc.).

[0018] The electronic, optical, and / or electro-optical components of the present disclosure are often disposed within a distal portion of a flexible elongate member. As used herein, the "distal portion" of a flexible elongate member includes any portion of the flexible elongate member from its midpoint to its distal tip. Because the flexible elongate member may be solid, some embodiments of the present disclosure include a housing portion at the distal portion for receiving the electronic components. Such a housing portion may be a tubular structure attached to the distal portion of the elongate member. Some flexible elongate members are tubular and have one or more lumens through which electronic components may be disposed within the distal portion.

[0019] The electronic, optical, and / or electro-optical components and associated communication lines are sized and shaped to allow the diameter of the flexible elongate member to be very small. For example, the outer diameter of an elongate member, such as a guidewire, catheter, or guidewire catheter, including one or more electronic, optical, and / or electro-optical components described herein, is from about 0.0007" (0.0178 mm) to about 0.118" (3.0 mm), with some specific embodiments having an outer diameter of from about 0.014" (0.3556 mm) to about 0.018" (0.4572 mm). Thus, flexible elongate members incorporating electronic, optical, and / or electro-optical components of the present application are suitable for use in a wide variety of lumens within a human patient, in addition to those that partially or directly surround the heart, including the veins and arteries of the limbs, the renal arteries, blood vessels in and around the brain, and other lumens.

[0020] As used herein, "connected" and variations thereof include direct connections, such as being directly adhered or otherwise secured to, onto, within, etc., another element, as well as indirect connections, where one or more elements are disposed between the connected elements.

[0021] "Fixed" and variations thereof, as used herein, includes methods in which an element is directly fixed to another element, for example, directly adhered or otherwise fixed to another element, as well as indirect techniques of fixing two elements together, where one or more elements are disposed between the fixed elements.

[0022] 1 , an intravascular system 100 according to one embodiment of the present disclosure is shown. In this regard, the intravascular system includes an intravascular device 102 and a connector 104. As will be described in more detail below, a communication cable 105 extends from the connector 104 coaxially or parallel to the longitudinal axis of the intravascular device 102. As a result of the communication cable 105 extending coaxially or parallel to the intravascular device, the connector 104 and the communication cable 105 are less likely to get caught on the patient, the patient's clothing, medical equipment (including tubing, catheters, wires, leads, etc.), and / or other structures within the procedure room when manipulating the intravascular device 102.

[0023] Referring now to FIG. 2 , a side view of an intravascular device 102 according to an embodiment of the present disclosure is provided. As shown, the intravascular device 102 includes a flexible elongate member 106 having a distal portion 107 adjacent a distal tip 108 and a proximal portion 109 adjacent a proximal end 110. A sensor 112 is disposed within the distal portion 107 of the flexible elongate member 106 proximal to the distal tip 108. Generally, the sensor 112 represents one or more electronic, optical, or electro-optical components. In that regard, the sensor 112 may include a pressure sensor, a flow sensor, a temperature sensor, an imaging element, an optical fiber, an ultrasound transducer, a reflector, a mirror, a prism, an ablation element, an RF electrode, a conductor, and / or combinations thereof. The particular type of component or combination of components may be selected based on the intended use of the intravascular device. In some examples, the sensor 112 is disposed less than 10 cm, less than 5 cm, or less than 3 cm from the distal tip 108. In some examples, the sensor 112 is disposed within a housing of the intravascular device 102. In that regard, the housing may in some examples be a separate component secured to the flexible elongate member 106. In other examples, the housing may be integrally formed as part of the flexible elongate member 106.

[0024] The intravascular device 102 also includes a connecting portion 114 adjacent the proximal portion 109 of the device. In that regard, the connecting portion 114 can be spaced a distance 116 from the proximal end 110 of the flexible elongate member 106. Generally, the distance 116 is between 0% and 50% of the overall length of the flexible elongate member 106. While the overall length of the flexible elongate member can be any length, in some embodiments, the overall length is between about 1300 mm and about 4000 mm, with some specific embodiments having lengths of 1400 mm, 1200 mm, and 3000 mm. In some examples, the connecting portion 114 is spaced from the proximal end 110 by a distance between about 0 mm and about 1400 mm. In some specific embodiments, the connecting portion 114 is spaced from the proximal end by a distance of 0 mm, 300 mm, and 1400 mm. Thus, in some examples, the connecting portion 114 is located at the proximal end 110. In some such embodiments, one or more aspects of the engagement and alignment mechanism of the intravascular device 102 discussed below may be located distal to the connecting portion 114 instead of proximal to the connecting portion 114, as shown in the embodiment of FIG. 2, or the engagement and alignment mechanism may be omitted entirely.

[0025] In the illustrated embodiment of FIG. 2 , intravascular device 102 includes a locking section 118 that extends proximally from connecting portion 114 to a knob or retaining portion 120 that extends to proximal end 110. In the illustrated embodiment, knob or retaining section 120 is rounded at proximal end 110. In other embodiments, knob or retaining section 120 has a tapered, arcuate, and / or other varying profile as it extends proximally to proximal end 110. In that regard, in some instances, the profile and / or diameter of knob or retaining section 120 decreases as it extends proximally to proximal end 110, such that the reduced profile and / or diameter of the proximal end facilitates easier introduction of one or more other instruments onto the intravascular device. In other embodiments, knob or retaining section 120 has a constant profile as it extends proximally to proximal end 110. The knob or retaining section 120 is sometimes referred to as the proximal section because it is proximal to the locking section 118 .

[0026] As shown, connecting portion 114 has a diameter 122 (or other similar measure of the outer cross-sectional profile for non-circular cross-sectional embodiments), while locking section 118 has a diameter 124 (again, or other similar measure of the outer cross-sectional profile for non-circular cross-sectional embodiments). Diameter 124 of locking section 118 is different from diameter 122 of connecting portion 114. In this regard, the different sizes of diameters 122, 124 create a structure configured to facilitate alignment and / or connection of intravascular device 102 to a connector, such as connector 104. In the illustrated embodiment, diameter 124 of locking section 118 is smaller than diameter 122 of connecting portion 114. In some embodiments, diameter 124 of locking section 118 is between about 40% and about 80% of diameter 122, and in some specific embodiments, is about 42%, 64%, and / or other percentages of diameter 122. In that regard, in some embodiments, diameter 122 of connecting portion 114 is between about 0.0178 mm and about 3.0 mm, and in some specific embodiments, 0.3556 mm (0.014"), 0.4572 mm (0.018"), and 0.889 mm (0.035") Accordingly, in some embodiments, diameter 124 of locking section 118 is between about 0.007 mm and about 2.4 mm, and in some specific embodiments, 0.186 mm (0.0073"), 0.23 mm, and 0.50 mm. In the illustrated embodiment, knob or retention section 120 has a diameter approximately equal to diameter 122 and therefore greater than diameter 124. However, in other embodiments, knob or retention section 120 has a diameter greater than diameter 122, less than diameter 122, greater than diameter 124, equal to diameter 124, and / or less than diameter 124. In some embodiments, the locking section 118 is a section of the core wire that extends through the connecting portion 114. The locking section 118 and the knob or retaining section 120 together may sometimes be referred to as a locking mechanism.

[0027] 2, locking section 118 extends proximally from connecting portion 114 a distance 126, and knob or retaining section 120 extends proximally a distance 128 from locking section 118 to proximal end 110. Together, distances 126 and 128 equal distance 116 that connecting portion 114 is spaced from proximal end 110 of intravascular device 102. In some examples, distance 126 is from about 0.020" to about 0.10", with some specific embodiments being 0.030", 0.040", and 0.060". Additionally, while the transitions between connecting portion 114 and locking section 118, and between locking section 118 and knob or retention section 120, are shown as stepped in the illustrated embodiment, in other embodiments the transitions are tapered and / or otherwise provide a gradual change in outer diameter along the length of the intravascular device. In some embodiments, the transitions are tapered. The use of a tapered and / or gradual transition results in the proximal portion of intravascular device 102 not having any sharp edges. In some implementations, the use of a tapered and / or gradual transition for one or both of the transitions between locking section 118 and either connecting portion 114 or knob or retaining section 120 makes it easier to clean the proximal portion of the device (e.g., remove any liquid or other undesirable material on the surface of the proximal portion of the intravascular device). In some embodiments, intravascular system 100 may include one or more features described in U.S. patent application Ser. No. 15 / 374,312, filed December 9, 2016, and entitled "SIDE-LOADING CONNECTORS FOR USE WITH INTRAVASCULAR DEVICES AND ASSOCIATED SYSTEMS AND METHODS," which is incorporated herein by reference in its entirety.

[0028] The connecting portion 114 is configured to facilitate communication between the intravascular device 102 and another device. More specifically, in some embodiments, the connecting portion 114 is configured to facilitate communication of data acquired by the sensor 112 to another device, such as a computing device or processor. Thus, in some embodiments, the connecting portion 114 includes one or more conductive portions. In some implementations, the connecting portion 114 may include a conductive band, ring, coating, coil, or the like. In some examples, the connecting portion 114 includes one or more electrical connectors or conductive portions, as described in U.S. Patent Application No. 13 / 931,052, filed June 28, 2013, entitled "INTRAVASCULAR DEVICES, SYSTEMS, AND METHODS," which is incorporated herein by reference in its entirety. In other embodiments, the connecting portion 114 includes an optical connector. In such examples, the connecting portion 114 provides an optical connection to one or more optical communication paths (e.g., fiber optic cables) that extend along the length of the flexible elongate member 106 and are optically coupled to the sensor 112. Furthermore, in some embodiments, the connecting portion 114 provides both an electrical connection and an optical connection to both electrical conductors and optical communication paths coupled to the sensor 112. In this regard, it is again noted that the sensor 112 may be comprised of multiple elements in some examples. In some cases, the connecting portion 114 may be configured to provide a physical connection, either directly or indirectly, to another device. In other cases, the connecting portion 114 may be configured to facilitate wireless communication between the intravascular device 102 and another device. In general, any current or future-developed wireless protocol may be utilized. In still other examples, the connecting portion 114 facilitates both a physical connection and a wireless connection to another device.

[0029] As mentioned above, in some examples, the connection portion 114 provides a connection between the sensor 112 of the intravascular device 102 and an external device. Accordingly, in some embodiments, one or more electrical conductors, one or more optical paths, and / or combinations thereof extend along the length of the flexible elongate member 106 between the connection portion 114 and the sensor 112 to facilitate communication between the connection portion 114 and the sensor 112. In general, any number of electrical conductors, optical paths, and / or combinations thereof may extend along the length of the flexible elongate member 106 between the connection portion 114 and the sensor 112. In some examples, between 1 and 10 electrical conductors (or conductive portions) and / or optical paths extend along the length of the flexible elongate member 106 between the connection portion 114 and the sensor 112. For clarity and brevity, the embodiments of the present disclosure described below include three electrical conductors, and therefore the connection portion 114 will be described as having three separate conductive portions corresponding to the three conductors.

[0030] In some embodiments, the flexible elongate member 106 includes multiple core wires. For example, the flexible elongate member 106 may include a proximal core wire (or proximal core) and a distal core wire (or distal core) attached to one another. Components associated with a proximal portion of the intravascular device 102 (e.g., including the proximal core wire) may be referred to as a proximal subassembly, and components associated with a distal portion of the intravascular device 102 (e.g., including the distal core wire) may be referred to as a distal subassembly. A flexible elongate member may refer to one or more components of the proximal subassembly and / or the distal subassembly. In some embodiments, the flexible elongate member 106 includes features as described in U.S. Patent Application No. 13 / 931,052, entitled "INTRAVASCULAR DEVICE, SYSTEMS, AND METHODS," filed June 28, 2013, which is incorporated herein by reference in its entirety.

[0031] 3 , in some examples, connecting portion 114 of intravascular device 102 includes conductive portions 132, 134, and 136 separated from each other and from the body of flexible elongate member 106 by insulating portions 138, 140, 142, and 144, with insulating portion 144 adjacent locking section 118. In that regard, conductive portions 132, 134, and 136 are formed from a conductive material and, in some examples, are portions of a hypotube, a coil, a conductive ink, a conductive coating formed on a tubular member, and / or combinations thereof. In some embodiments, conductive portions 132, 134, and 136 include features as described in U.S. Patent Application No. 14 / 143,304, entitled “INTRAVASCULAR DEVICES, SYSTEMS, AND METHODS,” filed December 30, 2013, which is incorporated herein by reference in its entirety. It is understood that the total number of communication paths and / or the number of conductors and / or optical paths may vary in other embodiments, and therefore the number of conductive portions (or optical connectors) included in the connection portion may also vary. More specifically, the number of communication paths and the number of conductors and optical paths extending along the length of the flexible elongate member 106 may be selected based on the desired functionality of the sensor 112 and the corresponding elements that define the sensor 112 to provide such functionality. As a result, the number and type of connections provided by the connection portion 114 are similarly determined by the desired functionality of the sensor 112, the corresponding elements that define the sensor 112 to provide such functionality, and the communication needs for such elements. Furthermore, in some examples, one or more of the insulating portions 138, 140, 142, and 144 are omitted. For example, as shown in the exemplary embodiment of FIG. 4, the insulating portion 144 is omitted.

[0032] 5, a schematic cross-sectional view of connecting portion 114, locking section 118, and knob or retaining section 120 of intravascular device 102 is shown, according to aspects of the present disclosure. In some embodiments, connecting portion 114 includes three conductive portions 132, 134, and 136 separated from each other and from the body of the flexible elongate member by insulating portions 138, 140, and 142. Because conductive portions 132, 134, and 136 and insulating portions 138, 140, and 142 are annular ring-shaped around the circumference of the flexible elongate member, their cross-sections appear on opposite sides of connecting portion 114. One, more, or all of conductive portions 132, 134, and 136 are electrically coupled to respective conductors or conductive elements (e.g., conductive wires 30, 40, 50). 5 , conductive portion 132 is electrically connected to conductive wire 30, conductive portion 134 is electrically connected to conductive wire 40, and conductive portion 136 is electrically connected to conductive wire 50. In some examples, conductive wires 30, 40, and 50 are disposed within an open space 182 defined by a hypotube 184 that forms part of the flexible elongate member. Conductive wires 30, 40, and 50 are electrically coupled to sensors and extend proximally through the flexible elongate member. In some embodiments, the flexible elongate member includes a metal core 150 that extends through connecting portion 114. In some implementations, locking section 118 and knob or retention section 120 are part of a single component called locking core 160. Locking core 160 is separate from metal core 150 and is attached by soldering to the proximal end of connecting portion 114 at interface 10 with conductive portion 136 and interface 20 with the proximal end of metal core 150.

[0033] Referring now to FIG. 6 , a schematic top view of an intravascular device 102 according to an aspect of the present disclosure is shown. The intravascular device 102 may be an intravascular guidewire sized and shaped for placement within a patient's blood vessel. The intravascular device 102 may include a sensor 112. For example, the sensor 112 may be a pressure sensor configured to measure the pressure of blood flow within the patient's blood vessel. The intravascular device 102 includes a flexible elongate member 106. The sensor 112 is disposed at a distal portion 107 of the flexible elongate member 106. The sensor 112 may be attached to the distal portion 107 within a housing 280 in some embodiments. A flexible tip coil 290 extends between the housing 280 and the distal end 108. A connecting portion 114 is disposed at a proximal portion 109 of the flexible elongate member 106. The connecting portion includes conductive portions 132, 134, 136 separated from each other and from the body of the flexible elongate member 106 by insulating portions 138, 140, 142, and 144. In some embodiments, the conductive portions 132, 134, 136 may be conductive ink printed and / or deposited around the flexible elongate member. In some embodiments, the conductive portions 132, 134, 136 are conductive metal rings disposed around the flexible elongate member. The locking section 118 and the knob or retaining section 120 are disposed on the proximal portion 109 of the flexible elongate member 106.

[0034] 6 includes a distal core 210 and a proximal core 220. The distal core 210 and the proximal core 220 are metal components that form part of the body of the intravascular device 102. For example, the distal core 210 and the proximal core 220 are flexible metal rods that provide structure for the flexible elongate member 106. The diameters of the distal core 210 and the proximal core 220 may vary along their lengths.

[0035] In some embodiments, intravascular device 102 has a distal assembly and a proximal assembly that are electrically and mechanically joined together to provide electrical communication between sensor 112 and conductive portions 132, 134, 136. For example, pressure data acquired by sensor 112 (in this example, sensor 112 is a pressure sensor) may be transmitted to conductive portions 132, 134, 136. Control signals from a computer in communication with intravascular device 102 may be transmitted to sensor 112 via conductive portions 132, 134, 136. The distal subassembly may include a distal core 210. The distal subassembly may also include sensor 112, conductive member 230, and / or one or more layers 240 of polymer / plastic that surround conductive member 230 and core 210. For example, the polymer / plastic layer may protect conductive member 230. The proximal subassembly may include a proximal core 220. The proximal subassembly may also include one or more layers of polymer layer 250 (hereinafter polymer layer 250) surrounding proximal core 220 and / or conductive ribbons 260 embedded within one or more layers of polymer layer 250. In some embodiments, the proximal subassembly and distal subassembly may be manufactured separately. During the assembly process for intravascular device 102, the proximal subassembly and distal subassembly may be electrically and mechanically joined together. As used herein, flexible elongate member may refer to one or more components along the length of intravascular device 102, one or more components of the proximal subassembly (e.g., including proximal core 220), and / or one or more components of the distal subassembly 210 (e.g., including distal core 210).

[0036] In various embodiments, the intravascular device 102 may include one, two, three, or more core wires extending along its length. For example, a single core wire may extend along substantially the entire length of the flexible elongate member 106. In such embodiments, the locking section 118 and the knob or retaining section 120 may be integrally formed on a proximal portion of the single core wire. The sensor 112 may be secured to a distal portion of the single core wire. In other embodiments, such as the embodiment shown in FIG. 6, the locking section 118 and the knob or retaining section 120 may be integrally formed on a proximal portion of the proximal core 220. The sensor 112 may be secured to a distal portion of the distal core 210. The intravascular device 102 includes one or more conductive members 230 in communication with the sensor 112. For example, the conductive members 230 may be one or more electrical wires in direct communication with the sensor 112. In some examples, the conductive member 230 is electrically and mechanically coupled to the sensor 112, for example, by soldering. In some examples, the conductive member 230 has two or three electrical wires (e.g., a bifilar cable or a trifilar cable). The individual electrical wires may include a bare metal conductor surrounded by one or more insulating layers. The conductive member 230 may extend along the length of the distal core 210. For example, at least a portion of the conductive member 230 may be helically wrapped around the distal core 210.

[0037] Intravascular device 102 includes one or more conductive ribbons 260 at a proximal portion of flexible elongate member 106. Conductive ribbon 260 is embedded within polymer layer 250. Conductive ribbon 260 is in direct communication with conductive portions 132, 134, and / or 136. In some examples, conductive member 230 is electrically and mechanically coupled to sensor 112, for example, by soldering. In some examples, conductive portions 132, 134, and / or 136 have a conductive ink (e.g., a metal nanoink, such as a silver or gold nanoink) deposited or printed on conductive ribbon 260.

[0038] As described herein, electrical communication between the conductive member 230 and the conductive ribbon 260 may be established at a connection region 270 of the flexible elongate member 106. By establishing electrical communication between the conductive member 230 and the conductive ribbon 260, the conductive portions 132, 134, 136 may be in electrical communication with the sensor 112.

[0039] In some embodiments, represented by FIG. 6, intravascular device 102 includes locking section 118 and knob or retaining section 120. Unlike locking core 160 of FIG. 5 (including locking section 118 and knob or retaining section 120), which is soldered to a metal core, locking section 118 and section 120 of FIG. 6 are integral with proximal core 220. To form locking section 118, a machining process is required to remove polymer layer 250 and conductive ribbon 260 within locking section 118 and to shape proximal core 220 within locking section 118 to the desired shape. As shown in FIG. 6, locking section 118 includes a reduced diameter, and knob or retaining section 120 has a diameter substantially similar to the diameter of proximal core 220 at connecting portion 114. In some examples, because the machining process removes the conductive ribbon in the locking section 118, the proximal end of the conductive ribbon 260 is exposed to moisture and / or liquids, such as blood, saline, disinfectant, and / or enzymatic cleaning solutions, and an insulating layer 158 is formed over the proximal end portion of the connecting portion 114 to insulate the exposed conductive ribbon.

[0040] FIG. 7 is a schematic side view of an intraluminal (e.g., intravascular) sensing system 100 including an intravascular device 102 having a conductive member 230 (e.g., a multifilar conductor bundle) and a conductive ribbon 260, according to an embodiment of the present disclosure. The intravascular device 102 may be an intravascular guidewire sized and shaped for placement within a patient's blood vessel. The intravascular device 102 includes a distal tip 108 and a sensor 113. For example, the sensor 113 may be a pressure sensor and / or a flow sensor configured to measure the pressure of blood flow within the patient's blood vessel, or another type of sensor, including, but not limited to, a temperature sensor or an imaging sensor, or a combination sensor measuring more than one characteristic. For example, flow data acquired by the flow sensor may be used to calculate a physiological variable, such as coronary flow reserve (CFR). The intravascular device 102 includes a flexible elongate member 106. The sensor 113 is disposed on a distal portion 107 of the flexible elongate member 106. In some embodiments, the sensor 113 may be mounted at the distal portion 107 within the housing 280. A flexible tip coil 290 extends distally from the housing 282 at the distal portion 107 of the flexible elongate member 106. The connecting portion 114, located at the proximal end of the flexible elongate member 106, includes conductive portions 132, 134. In some embodiments, the conductive portions 132, 134 may be conductive ink printed and / or deposited around the connecting portion 114 of the flexible elongate member 106. In some embodiments, the conductive portions 132, 134 may be metal bands or rings that are conductive and disposed around the flexible elongate member. A locking region is formed by a collar or locking section 118, and a knob or retention section 120 is disposed on the proximal portion 109 of the flexible elongate member 106.

[0041] The intravascular device 102 of FIG. 7 includes a core wire having a distal core 210 and a proximal core 220. The distal core 210 and the proximal core 220 are metal components that form part of the body of the intravascular device 102. For example, the distal core 210 and the proximal core 220 may be flexible metal rods that provide structure for the flexible elongate member 106. The distal core 210 and / or the proximal core 220 may be made from a metal or metal alloy. For example, the distal core 210 and / or the proximal core 220 may be made from stainless steel, nitinol, a nickel-cobalt-chromium-molybdenum alloy (e.g., MP35N), and / or other suitable materials. In some embodiments, the distal core 210 and the proximal core 220 are made from the same material. In other embodiments, the distal core 210 and the proximal core 220 are made from different materials. The diameters of the distal core 210 and the proximal core 220 may vary along their respective lengths. The junction between the distal core 210 and the proximal core 220 is surrounded and housed by a hypotube 215. The sensor 113 may optionally be located at the distal end of the distal core 210.

[0042] In some embodiments, the intravascular device 102 has a distal subassembly and a proximal subassembly that are electrically and mechanically joined together, creating electrical communication between the sensor 113 and the conductive portions 132, 134. For example, flow data acquired by the sensor 113 (in this example, the sensor 113 is a flow sensor) may be transmitted to the conductive portions 132, 134. In an exemplary embodiment, the sensor 113 is a single ultrasonic transducer element. The transducer element emits an ultrasonic signal and receives echoes. The transducer element generates an electrical signal representing the echo. Signal-carrying filers carry this electrical signal from the sensor in the distal portion to a connector in the proximal portion. The processing system 306 processes the electrical signal to extract the fluid flow rate.

[0043] Control signals from a processing system 306 (e.g., a processor circuit of the processing system 306) in communication with the intravascular device 102 may be sent to the sensor 113 via a connector 314 attached to the conductive portions 132, 134. The distal subassembly may include a distal core 210. The distal subassembly may also include one or more layers of insulating polymer / plastic 240 surrounding the sensor 113, the conductive members 230, and / or the conductive members 230 and the core 210. For example, the polymer / plastic layer may insulate and protect the conductive members of the multifilar cable or conductor bundle 230. The proximal subassembly may include a proximal core 220. The proximal subassembly may also include one or more polymer layers 250 (hereinafter polymer layers 250) surrounding the proximal core 220 and / or the conductive ribbons 260, which are embedded within one or more insulating and / or protective polymer layers 250. In some embodiments, the proximal subassembly and the distal subassembly are manufactured separately. During the assembly process for the intravascular device 102, the proximal subassembly and the distal subassembly may be electrically and mechanically joined together. As used herein, a flexible elongate member may refer to one or more components along the entire length of the intravascular device 102, one or more components of the proximal subassembly (e.g., including the proximal core 220), and / or one or more components of the distal subassembly (e.g., including the distal core 210). Thus, a flexible elongate member may refer to the combined proximal and distal subassemblies described above. The junction between the proximal core 220 and the distal core 210 is surrounded by a hypotube 215.

[0044] In various embodiments, intravascular device 102 may include one, two, three, or more core wires extending along its length. For example, a single core wire may extend along substantially the entire length of flexible elongate member 106. In such embodiments, locking section 118 and section 120 may be integrally formed at a proximal portion of the single core wire. Sensor 113 may be secured to a distal portion of the single core wire. In other embodiments, such as the embodiment shown in FIG. 7, locking section 118 and section 120 may be integrally formed at a proximal portion of proximal core 220. Sensor 113 may be secured to a distal portion of distal core 210. Intravascular device 102 includes one or more conductive members 230 (e.g., a multifilar conductor bundle or cable) in communication with sensor 113. For example, conductive member 230 may be one or more electrical wires in direct communication with sensor 113. In some examples, the conductive member 230 is electrically and mechanically coupled to the sensor 113, for example, by soldering. In some examples, the conductor bundle 230 has two or three electrical wires (e.g., a bifilar or trifilar cable). The individual electrical wires may include bare metal conductors surrounded by one or more insulating layers. The conductive member 230 may extend along the length of the distal core 210. For example, at least a portion of the conductive member 230 may be helically wrapped around the distal core 210 to minimize or eliminate whipping of the distal core in tortuous anatomical structures.

[0045] Intravascular device 102 includes one or more conductive ribbons 260 in a proximal portion of flexible elongate member 106. Conductive ribbon 260 is embedded within polymer layer 250. Conductive ribbon 260 is in direct communication with conductive portions 132 and / or 134. In some examples, multifilar conductor bundle 230 is electrically and mechanically coupled to sensor 113, for example, by soldering. In some examples, conductive portions 132 and / or 134 have conductive ink (e.g., a metal nano-ink such as a copper, silver, gold, or aluminum nano-ink) deposited or printed on conductive ribbon 260.

[0046] As described herein, electrical communication between the conductive member 230 and the conductive ribbon 260 may be established at the connecting portion 114 of the flexible elongate member 106. By establishing electrical communication between the conductor bundle 230 and the conductive ribbon 260, the conductive portions 132, 134 may be in electrical communication with the sensor 113.

[0047] 7, the intravascular device 102 includes a locking section 118 and a knob or retaining section 120. To form the locking section 118, a machining process is used to remove the polymer layer 250 and the conductive ribbon 260 at the locking section 118 and to form the proximal core 220 at the locking section 118 into a desired shape. As shown in FIG. 7, the locking section 118 includes a reduced diameter, and the knob or retaining portion has a diameter substantially similar to the diameter of the proximal core 220 at the connecting portion 114. In some examples, because the machining process removes the conductive ribbon at the locking section 118, the proximal end of the conductive ribbon 260 is exposed to moisture and / or liquids, such as blood, saline, disinfectant, and / or enzymatic cleaning solutions, and an insulating layer 158 is formed over the proximal end portion of the connecting portion 114 to insulate the exposed conductive ribbon 260.

[0048] In some embodiments, the connector 314 provides electrical connectivity between the conductive portions 132, 134 and the patient interface monitor 304. The patient interface monitor (PIM) 304 may optionally connect to a console or processing system 306 that includes or communicates with a display 308.

[0049] The system 100 may be located in a catheterization lab having a control room. The processing system 306 may be located in the control room. Optionally, the processing system 306 may be located elsewhere, such as in the catheterization lab itself. A catheterization lab may include a sterile field, while its associated control room may or may not be sterile depending on the procedure to be performed and / or the medical facility. In some embodiments, the device 102 may be controlled from a remote location, such as a control room, so that an operator does not need to be in close proximity to the patient.

[0050] The intraluminal device 102, PIM 304, and display 308 may be communicatively coupled directly or indirectly to the processing system 306. These elements may be communicatively coupled to the medical processing system 306 via a wired connection, such as a standard copper multifilar conductor bundle 230. The processing system 306 may be communicatively coupled to one or more data networks, for example, a TCP / IP-based local area network (LAN). In other embodiments, a different protocol, such as a synchronous optical network (SONET), may be utilized. In some cases, the processing system 306 may be communicatively coupled to a wide area network (WAN).

[0051] The PIM 304 forwards the received signals to a processing system 306, where the information is processed and displayed on a display 308 (e.g., as physiological data in graphical, symbolic, or alphanumeric format). The console or processing system 306 may include a processor and memory. The processing system 306 may be operable to facilitate the functionality of the intravascular sensing system 100 described herein. For example, the processor may execute computer-readable instructions stored on a non-transitory, tangible, computer-readable medium.

[0052] The PIM 304 facilitates communication of signals between the processing system 306 and the intraluminal device 102. The PIM 304 may be communicatively disposed between the processing system 306 and the intraluminal device 102. In some embodiments, the PIM 304 performs pre-processing of the data before relaying the data to the processing system 306. In an example of such an embodiment, the PIM 304 performs amplification, filtering, and / or aggregation of the data. In one embodiment, the PIM 304 also provides high-voltage and low-voltage DC power to support operation of the intraluminal device 102 via the conductive members 230.

[0053] A multifilar cable or transmission line bundle 230 can include multiple conductors, including one, two, three, four, five, six, seven, or more conductors. In the example shown in FIG. 7 , the multifilar conductor bundle 230 includes two straight sections 232 and 236, which are positioned parallel to the longitudinal axis of the flexible elongate member 106 and include a helical section 234. The multifilar conductor bundle 230 is wrapped around the exterior of the flexible elongate member 106 and then overcoated with an insulating and / or protective polymer 240. Communication along the multifilar conductor bundle 230 may be via a number of methods or protocols, including serial, parallel, etc., with one or more filers of the bundle 230 carrying signals, if any. One or more filers of the multifilar conductor bundle 230 may also carry direct current (DC) power, alternating current (AC) power, or function as a ground connection.

[0054] The display or monitor 308 may be a display device such as a computer monitor or other type of screen. The display or monitor 308 may be used to display selectable prompts, instructions, and visualization of imaging data to the user. In some embodiments, the display 308 may be used to provide the user with a procedure-specific workflow for completing an endoluminal imaging procedure.

[0055] FIG. 8 is a schematic perspective top view of an intravascular system showing a connector in an open position according to the present disclosure. As shown in FIG. 8 , an embodiment of an intravascular system 800 having an intravascular device 102 and a connector 104 according to the present disclosure is shown therein. Connector 104 includes a component 804 and a component 806. Component 804 includes a recess 808 sized and shaped to receive intravascular device 102. Component 806 is movable relative to component 804. In particular, component 806 is slidable relative to component 804 to facilitate insertion of intravascular device 102 into connector 104 and subsequent engagement of the connector with the received intravascular device resulting in one or more electrical connections between the intravascular device and the connector. The sliding movement of component 806 relative to component 804 can be parallel to the longitudinal axis of component 804 and / or the longitudinal axis of the intravascular device received within connector 104. The communication cable 105 extends from the connector 104 such that the communication cable 105 is coaxial or parallel to the intravascular device 102 received within the connector 104 .

[0056] 9 shows a schematic cross-sectional view of connector 104. In some embodiments, component 806 includes split open-comb electrical contacts 932A, 932B, 934A, 934B, and 936. Component 804 includes locking clip 200. Locking clip 200 includes slit 201 sized and shaped to receive locking section 118, with section 120 proximal to locking clip 200. When connecting portion 114 is received within recess 208 and locking section 118 is received within slit 201, conductive portion 132 is aligned with electrical contacts 932A and 932B along the direction of relative movement between components 204 and 206. Similarly, conductive portion 134 is aligned with electrical contacts 934A and 934B, and conductive portion 136 is aligned with electrical contact 936 along the same direction of movement. In some embodiments, conductive portions 132, 134, and 136 are separated by insulating portions 138, 140, and 142. In some examples, connecting portion 114 also includes insulating portion 144 distal to locking section 118. Because locking section 118 has a reduced diameter compared to section 120 and insulating portion 144 (or conductive portion 136 if insulating portion 144 is not present), connecting portion 114 is prevented from moving in either a distal or proximal direction along its length.

[0057] Furthermore, the open comb electrical contacts are particularly well-suited to facilitate proper electrical connection between the connector 104 and the intravascular device 102 disposed within the recess 808 of the component 804 when the component 806 is translated from an open position toward a closed position relative to the component 804. Furthermore, the open comb configuration allows the intravascular device to be rotated relative to the connector while maintaining proper electrical connection. Thus, the open comb configuration allows a user (e.g., a surgeon) to keep the connector 104 connected to the intravascular device while the intravascular device is moved or advanced through the vasculature with little resistance to the rotational movement of the intravascular device. In other words, the intravascular device can be moved through the vasculature, undergoing various twists and turns, without the connector 104 having to move with the rotation of the intravascular device. The open comb configuration also helps ensure good electrical contact due to the multiple fingers on each of the contacts. Additionally, the open ends of the open comb configuration provide good guides to ensure accurate placement of the intravascular device when the component 806 is closed. Although various advantages of the open comb configuration have been described, it will be appreciated that any suitable size electrical contacts may be utilized, including single contacts or multiple contacts.

[0058] Before proceeding, please note that the above examples are provided for illustrative purposes and are not intended to be limiting. Other devices and / or device configurations may be utilized to perform the operations described herein.

[0059] 10 is a schematic cross-sectional view of the connecting portion 114, locking section 118, and knob or retaining section 120 of the flexible elongate member 106, according to aspects of the present disclosure. In some embodiments, the connecting portion 114 includes three conductive portions 132, 134, and 136 separated from each other and from the body of the flexible elongate member by insulating portions 138, 140, 142, and 144. Because the conductive portions 132, 134, 136 and the insulating portions 138, 140, 142, and 144 are annular ring-shaped around the circumference of the flexible elongate member, their cross-sections appear on opposite sides of the connecting portion 114. In some embodiments, one or more magnets may be embedded within the polymer layer of the connecting portion 114. For example, magnet 1012 may be embedded in polymer layer 180 of insulating portion 138, magnet 1014 may be embedded in polymer layer 180 of insulating portion 140, magnet 1016 may be embedded in polymer layer 180 of insulating portion 142, and magnet 1018 may be embedded in polymer layer 180 of insulating portion 144. In some embodiments, magnets 1012, 1014, 1016, and 1018, when combined with magnets in connector 104 described below, pull flexible elongate member 106 down into recess 208, such that flexible elongate member 106 is positioned within recess 208 of connector 140, locking section 118 is aligned with slot 201, and conductive portions 132, 134, and 136 are longitudinally aligned with split open comb electrical contacts 932A, 932B, 934A, 934B, and 936 of connector 104. In some embodiments, the magnets 1012, 1014, 1016, and 1018 are attracted to the metal in the connector 104 and pull the flexible elongate member 106 down into the recess 208, such that the flexible elongate member 106 is positioned within the recess 208 of the connector 140, the locking section 118 is aligned with the slot 201, and the conductive portions 132, 134, and 136 are longitudinally aligned with the split open comb electrical contacts 932A, 932B, 934A, 934B, and 936 of the connector 104.In some examples, insulating portions 138, 140, 142, and 144 can be segments or regions (not separate components) of polymer layer 180, such as a polymer layer in which conductive ribbons are embedded.

[0060] 11 illustrates a cross-sectional view of the connecting portion 114 of the flexible elongate member 106 of FIG. 10 taken along cross section line AA, in accordance with aspects of the present disclosure. In some embodiments, the connecting portion 114 includes a metal core 150, a conductive ribbon 260, and a polymer layer 180 that insulates the conductive ribbons 260 from each other and from the metal core 150. In some embodiments, one or more magnets may be embedded within the polymer layer 180 of the connecting portion 114. For example, a magnet 1012 may be embedded within the polymer layer 180.

[0061] 12A and 12B are schematic cross-sectional views of the connecting portion 114, locking section 118, and knob or retaining section 120 of the flexible elongate member 106 according to an embodiment of the present disclosure. FIG. 13 shows a cross-sectional view of the connecting portion 114 of the flexible elongate member 106 of FIG. 12A and / or FIG. 12B taken along line BB according to an embodiment of the present disclosure. FIG. 12A, FIG. 12B, and FIG. 13 include similar features to those described in FIG. 10 and FIG. 11. In the embodiment of FIG. 12A, FIG. 12B, and FIG. 13, the magnets 1212, 1214, 1216, and 1218 are formed in an annular ring shape around the circumference of the connecting portion 114. In some embodiments, when magnet 1212 is combined with magnets 1214, 1216, and 1218, and with magnets in connector 104 described below, it pulls flexible elongate member 106 down into recess 208, such that flexible elongate member 106 is positioned within recess 208 of connector 140, locking section 118 is aligned with slot 201, and conductive portions 132, 134, and 136 are longitudinally aligned with split open comb electrical contacts 932A, 932B, 934A, 934B, and 936 of connector 104. In some embodiments, the magnets 1012, 1014, 1016, and 1018 are attracted to the metal in the connector 104 and pull the flexible elongated member 106 down into the recess 208, such that the flexible elongated member 106 is positioned within the recess 208 of the connector 140, the locking section 118 is aligned with the slot 201, and the conductive portions 132, 134, and 136 are longitudinally aligned with the split open comb electrical contacts 932A, 932B, 934A, 934B, and 936 of the connector 104.

[0062] Figure 12B differs from Figure 12A in that connecting portion 114 in Figure 12B is longer (e.g., greater longitudinally) than connecting portion 114 in Figure 12A. Figure 12B may be advantageous in situations where space is not available at the outer diameter of intravascular device 102 for additional components, such as magnets 1212, 1214, 1216, and 1218. By extending the length of intravascular device 102 (e.g., connecting portion 114), additional space is created in the length of intravascular device 102 for magnets 1212, 1214, 1216, and 1218 (while the outer diameter of intravascular device 102 remains the same). Magnets 1212, 1214, 1216, and 1218 can be directly adjacent to insulating portions 138-144, respectively. Insulating portions 138-144 can be spaced apart from magnets 1212, 1214, 1216, and 1218 and from conductive portions 132, 134, and 136. In some examples, magnets 1212, 1214, 1216, and 1218 can be directly adjacent to conductive portions 132, 134, and 136. The outer surfaces of magnets 1212, 1214, 1216, and 1218, the outer surfaces of conductive portions 132, 134, and 136, and the outer surfaces of insulating portions 138-144 can be continuous with one another.

[0063] Although typically a plurality of magnets 1212, 1214, 1216, and 1218, connecting portion 114 can include one, two, three, four, or more magnets.

[0064] In some examples, the magnet can directly surround the core wire 150 of FIG. 13 such that the magnet directly contacts the core wire 150 .

[0065] 14 , a schematic top view of connector 104 of intravascular system 100 while the connector is in an open position is shown, according to an embodiment of the present disclosure. The exemplary connector 104 shown in FIG. 14 includes a component 204 and a component 206. Component 204 includes a recess 208 sized and shaped to receive connecting portion 114 of flexible elongate member 106. Component 206 is movable relative to component 204. In particular, component 206 is slidable relative to component 204 to facilitate insertion of intravascular device 102 into connector 104 and subsequent engagement of connector 104 with the received intravascular device 102, resulting in one or more electrical connections between intravascular device 102 and connector 104. The sliding movement of component 206 relative to component 204 can be parallel to the longitudinal axis of component 204 and / or the longitudinal axis of intravascular device 102 received within connector 104. Component 204 includes locking clip 200. Locking clip 200 includes slit 201 sized and shaped to receive locking section 118, with section 120 proximal to locking clip 200.

[0066] In some embodiments, one or more magnets may be disposed within connector 104. For example, magnets 1412, 1414, 1416, and 1418 may be disposed beneath the respective regions where insulating portions 138, 140, 142, and 144 of connecting portion 114 of flexible elongate member 106 will be disposed when intravascular device 102 is inserted into connector 104. In some embodiments, magnets 1412, 1414, 1416, and 1418 are advantageously disposed adjacent to or in close proximity to conductive portions 132, 134, and 136. In some embodiments, magnets 1412, 1414, 1416, and 1418 have polarities opposite to those of magnets 1012, 1014, 1016, and 1018 within connecting portion 114 of flexible elongate member 106. Thus, in some embodiments, the magnetic attraction between magnets 1412, 1414, 1416, and 1418 and magnets 1012, 1014, 1016, and 1018 pulls flexible elongate member 106 down into recess 208, such that flexible elongate member 106 is positioned within recess 208 of connector 140, locking section 118 is aligned with slot 201, and conductive portions 132, 134, and 136 are longitudinally aligned with split open comb electrical contacts 932A, 932B, 934A, 934B, and 936 of connector 104. In some embodiments, magnets 1412, 1414, 1416, and 1418 attract metal within intravascular device 102 and pull flexible elongate member 106 down into recess 208, such that flexible elongate member 106 is positioned within recess 208 of connector 140, locking section 118 is aligned with slot 201, and conductive portions 132, 134, and 136 are longitudinally aligned with split open comb electrical contacts 932A, 932B, 934A, 934B, and 936 of connector 104.

[0067] FIG. 15 is a schematic cross-sectional side view of connector 104 according to aspects of the present disclosure. FIG. 15 illustrates how the conductive portion engages with split open comb electrical contacts 232A, 232B, 234A, 234B, and 236 and how locking section 118 is received within slit 201 of locking clip 200. In some examples, each of the electrical contacts has two arms that bend upward and two arms that bend downward. Also, each of the electrical contacts can have more or fewer arms that bend in different directions. For example, each of the electrical contacts may have one or three arms that bend upward and one or three arms that bend downward. In some embodiments, slit 201 extends halfway up the height of locking clip 200. Advantageously, engagement of locking section 118 of locking clip 200 with slit 201 ensures a reliable electrical connection between conductive portions 132, 134, and 136 of connecting portion 114 and split open comb electrical contacts 232A, 232B, 234A, 234B, and 236 in connector 104. In some embodiments, magnets 1412, 1414, 1416, and 1418 have polarities opposite to those of magnets 1012, 1014, 1016, and 1018 in connecting portion 114 of flexible elongate member 106. Thus, in some embodiments, the magnetic attraction between magnets 1412, 1414, 1416, and 1418 and magnets 1012, 1014, 1016, and 1018 pulls flexible elongate member 106 down into recess 208, such that flexible elongate member 106 is positioned within recess 208 of connector 140, locking section 118 is aligned with slot 201, and conductive portions 132, 134, and 136 are longitudinally aligned with split open comb electrical contacts 932A, 932B, 934A, 934B, and 936 of connector 104.In some embodiments, magnets 1412, 1414, 1416, and 1418 attract metal within intravascular device 102 and pull flexible elongate member 106 down into recess 208, such that flexible elongate member 106 is positioned within recess 208 of connector 140, locking section 118 is aligned with slot 201, and conductive portions 132, 134, and 136 are longitudinally aligned with split open comb electrical contacts 932A, 932B, 934A, 934B, and 936 of connector 104.

In some embodiments, when magnet 1612 is combined with magnets 1614 and 1616, and with the magnets in connector 104 described below, it pulls flexible elongate member 106 down into recess 208, such that flexible elongate member 106 is positioned within recess 208 of connector 140, locking section 118 is aligned with slot 201, and conductive portions 132, 134, and 136 are longitudinally aligned with split open comb electrical contacts 932A, 932B, 934A, 934B, and 936 of connector 104. In some embodiments, when magnet 1612 is combined with magnets 1614 and 1616, it is attracted to the metal in connector 104 and pulls flexible elongate member 106 down into recess 208, such that flexible elongate member 106 is positioned within recess 208 of connector 140, locking section 118 is aligned with slot 201, and conductive portions 132, 134, and 136 are longitudinally aligned with split open comb electrical contacts 932A, 932B, 934A, 934B, and 936 of connector 104.

Magnet 1812 may be positioned between split open comb electrical contacts 932A and 932B, magnet 1814 may be positioned between split open comb electrical contacts 934A and 934B, and magnet 1816 may be positioned offset from split open comb electrical contact 936. In some embodiments, magnets 1812, 1814, and 1816 have polarities opposite to the polarities of magnets 1612, 1614, and 1616 in connecting portion 114 of flexible elongate member 106. Thus, in some embodiments, magnetic attraction between magnets 1812, 1814, and 1816 and magnets 1612, 1614, and 1616 pulls flexible elongate member 106 down into recess 208 such that flexible elongate member 106 is positioned within recess 208 of connector 140, locking section 118 is aligned with slot 201, and conductive portions 132, 134, and 136 are longitudinally aligned with split open comb electrical contacts 932A, 932B, 934A, 934B, and 936 of connector 104.

In some embodiments, magnets 2420 and 2422 have polarities opposite to the polarities of magnets 2020 and 2022 within connecting portion 114 of flexible elongate member 106. Thus, in some embodiments, the magnetic attraction between magnets 2420 and 2422 and magnets 2020 and 2022 pulls flexible elongate member 106 down into recess 208 such that flexible elongate member 106 is positioned within recess 208 of connector 140, locking section 118 is aligned with slot 201, and conductive portions 132, 134, and 136 are longitudinally aligned with split open comb electrical contacts 932A, 932B, 934A, 934B, and 936 of connector 104. In some embodiments, magnet 2422 has a polarity opposite to that of magnet 2224 in connecting portion 114 of flexible elongate member 106. Thus, in some embodiments, the magnetic attraction between magnet 2422 and magnet 2224 pulls flexible elongate member 106 down into recess 208, such that flexible elongate member 106 is positioned within recess 208 of connector 140, locking section 118 is aligned with slot 201, and conductive portions 132, 134, and 136 are longitudinally aligned with split open comb electrical contacts 932A, 932B, 934A, 934B, and 936 of connector 104.

[0074] FIG. 25 is a schematic cross-sectional side view of connector 104 according to aspects of the present disclosure. FIG. 25 includes similar features as those described in FIG. 15. In some embodiments, magnets 2420 and 2422 have polarities opposite to those of magnets 2020 and 2022 in connecting portion 114 of flexible elongate member 106. Thus, magnetic attraction between magnets 2420 and 2422 and magnets 2020 and 2022 pulls flexible elongate member 106 down into recess 208 such that flexible elongate member 106 is disposed within recess 208 of connector 140, locking section 118 is positioned in alignment with slot 201, and conductive portions 132, 134, and 136 are longitudinally aligned with split open comb electrical contacts 932A, 932B, 934A, 934B, and 936 of connector 104. In some embodiments, the magnets 2420 and / or 2422 are attracted to the metal within the intravascular device 102 and pull the flexible elongate member 106 down into the recess 208, such that the flexible elongate member 106 is positioned within the recess 208 of the connector 140, the locking section 118 is aligned with the slot 201, and the conductive portions 132, 134, and 136 are longitudinally aligned with the split open comb electrical contacts 932A, 932B, 934A, 934B, and 936 of the connector 104.

[0075] To further illustrate details of locking clip 200, a proximal portion of connector 104, according to aspects of the present disclosure, is enlarged and shown in FIG. 26 . In some embodiments, locking clip 200 includes an upper portion 205 that slopes proximally at an oblique angle. The oblique angle is defined between a plane in which upper portion 205 resides and a plane in which the remainder of locking clip 200 resides. In some embodiments, the oblique angle is between 10 and 90 degrees. When locking section 118 is received within slit 201 of locking clip 200, proximally sloped upper portion 205 prevents locking section 118 from sliding upwardly out of slit 201. Advantageously, engagement of locking section 118 with slit 201 of locking clip 200 ensures a reliable electrical connection between conductive portions 132, 134, and 136 of connecting portion 114 and split open comb electrical contacts 232A, 232B, 234A, 234B, and 236 within connector 104. Again, magnet 2420 is positioned below locking clip 200 and magnet 2422 is positioned proximate to locking clip 200, and in some embodiments, magnets 2020 and 2022 and / or magnet 2224 are attracted to magnet 2420 and / or magnet 2422, pulling flexible elongate member 106 down into recess 208 and positioned within recess 208 of connector 140, locking section 118 is positioned in alignment with slot 201, and conductive portions 132, 134, and 136 are longitudinally aligned with split open comb electrical contacts 932A, 932B, 934A, 934B, and 936 of connector 104. In some embodiments, metal within intravascular device 102 is attracted to magnet 2420 and / or magnet 2422, pulling flexible elongate member 106 down into recess 208 and positioning it within recess 208 of connector 140, with locking section 118 aligned with slot 201 and conductive portions 132, 134, and 136 longitudinally aligned with split open comb electrical contacts 932A, 932B, 934A, 934B, and 936 of connector 104.

[0076] 27 is a schematic top view of locking clip 200 from direction T shown in FIG. 26 according to aspects of the present disclosure. In some embodiments, locking section 118 includes distal subsection 168, central subsection 170, and proximal subsection 178. When locking section 118 is received within slit 201 of locking clip 200, movement of locking section 118 relative to locking clip 200 is limited to the length of central subsection 170. Proximally sloping upper portion 205 can engage proximal portion 178 and section 120 to prevent locking section 118 from sliding out of slit 201. Again, magnet 2420 is positioned below locking clip 200 and magnet 2422 is positioned proximate to locking clip 200, and in some embodiments, magnets 2020 and 2022 and / or magnet 2224 are attracted to magnet 2420 and / or magnet 2422, pulling flexible elongate member 106 down into recess 208 and positioned within recess 208 of connector 140, locking section 118 is positioned in alignment with slot 201, and conductive portions 132, 134, and 136 are longitudinally aligned with split open comb electrical contacts 932A, 932B, 934A, 934B, and 936 of connector 104. In some embodiments, metal within intravascular device 102 is attracted to magnet 2420 and / or magnet 2422, pulling flexible elongate member 106 down into recess 208 and positioning it within recess 208 of connector 140, with locking section 118 aligned with slot 201 and conductive portions 132, 134, and 136 longitudinally aligned with split open comb electrical contacts 932A, 932B, 934A, 934B, and 936 of connector 104.

[0077] FIG. 28 is a schematic proximal view of locking clip 200 from direction P shown in FIG. 26 , according to aspects of the present disclosure. In some examples, locking section 118 is received within slit 201 of locking clip 200. Upper portion 205 slopes proximally at an oblique angle. In some embodiments, slit 201 extends partway up the height of locking clip 200. In some embodiments, magnet 2020 within flexible elongate member 106 is attracted to magnet 2420 disposed below locking clip 200, such that flexible elongate member 106 is pulled down into recess 208 and positioned within recess 208 of connector 140, locking section 118 is positioned in alignment with slot 201, and conductive portions 132, 134, and 136 are longitudinally aligned with split open comb electrical contacts 932A, 932B, 934A, 934B, and 936 of connector 104. In some embodiments, metal within the intravascular device 102 is attracted to a magnet 2420 positioned below the locking clip 200, resulting in the flexible elongate member 106 being pulled down into the recess 208 and positioned within the recess 208 of the connector 140, with the locking section 118 aligned with the slot 201 and the conductive portions 132, 134, and 136 longitudinally aligned with the split open comb electrical contacts 932A, 932B, 934A, 934B, and 936 of the connector 104.

[0078] FIG. 29 is a schematic cross-sectional view of the connecting portion 114, locking section 118, and knob or retaining section 120 of the flexible elongate member 106, according to an embodiment of the present disclosure. FIG. 29 can include similar embodiments as those described with respect to FIGS. 10, 12A, 12B, 16, 20, and / or 22. FIG. 30 shows a cross-sectional view of the connecting portion 114 of the flexible elongate member 106 of FIG. 29 taken along line FF, according to an embodiment of the present disclosure. FIG. 30 can include similar embodiments as those described with respect to FIGS. 11, 13, 17, 21, and / or 23. FIGS. 29 and 30 illustrate that the conductive portions 138, 140, 142, 144 and the magnets 1012, 1014, 1016, 1018 can be the same respective components. For example, a conductive band used to transmit an electrical signal is a magnet. That is, conductive portion 138 and magnet 1012 are one and the same component, conductive portion 140 and magnet 1014 are one and the same component, conductive portion 142 and magnet 1016 are one and the same component, and / or conductive portion 144 and magnet 1018 are one and the same component. In some examples, as shown in FIG. 30 , one and the same component (conductive portion 144 and magnet 1018) completely surrounds and contacts core wire 150. In some examples, a space is provided radially between one and the same component (conductive portion 144 and magnet 1018) and core wire 150.

[0079] Thus, incorporating magnets at strategic locations within the connector and / or the connecting portion of the flexible elongate member of the intravascular device can be seen to pull the flexible elongate member down into the recess of the connector and position the flexible elongate member so that the locking section is aligned within the slot and the conductive portion is longitudinally aligned with the split open comb electrical contacts of the connector. This provides for proper use of the locking core mechanism within the connector, thus tending to reduce the risk of misconnection and damage to the proximal end of the flexible elongate member.
