[0003] Hospital-acquired infections remain a problem in patient care facilities due to compromised sterility. They typically lead to prolonged hospital stays, increased complications, and higher healthcare costs. Drapes are commonly used as a sterile barrier between sterile and non-sterile environments. Medical procedures often involve connecting non-sterile medical devices to sterile medical equipment. In cases where a sterile medical device must be physically connected to a non-sterile device, the connection extends across or through the sterile barrier. Therefore, compromised sterility resulting from connections that cross the sterile barrier is often a concern. This paper discloses systems and methods for addressing the aforementioned problems.

[0032] Before disclosing some specific embodiments in more detail, it should be understood that the specific embodiments disclosed herein do not limit the scope of the concepts provided herein. It should also be understood that the specific embodiments disclosed herein may have features that can be easily separated from the specific embodiments, and these features may optionally be combined with or replace features of any of the many other embodiments disclosed herein.

[0033] Regarding the terminology used herein, it should be understood that these terms are for the purpose of describing certain specific embodiments and do not limit the scope of the concepts presented herein. Ordinal numbers (e.g., first, second, third, etc.) are generally used to distinguish or identify different features or steps in a set of features or steps and do not provide for a sequence or numerical limitation. For example, the features or steps “first,” “second,” and “third” do not necessarily appear in that order, and a particular embodiment including such features or steps is not necessarily limited to these three features or steps. For convenience, labels such as “left,” “right,” “top,” “bottom,” “front,” “back,” etc., are used, and these labels are not intended to imply, for example, any particular fixed position, orientation, or direction. Rather, such labels are used to reflect, for example, relative position, orientation, or direction. The singular forms “a,” “an,” and “the” include plural references unless the context clearly specifies otherwise.

[0034] The phrases “connected to,” “linked with,” and “connected to” refer to any form of interaction between two or more entities, including but not limited to mechanical, electrical, magnetic, electromagnetic, fluid, and thermal interactions. Two components can be connected to each other even if they are not in direct contact. For example, two components can be connected to each other through an intermediate component.

[0035] The terms "proximal" and "distal" refer to opposite ends of a medical device, including the device disclosed herein. More specifically, the proximal end of a medical device is the end closest to the practitioner during use, and the distal end of a medical device is the end or portion closest to the patient during use. For example, the distal or distal portion of a heart needle is the end or portion of the heart needle that is furthest from the patient's body. Conversely, the proximal or proximal portion of a heart needle is the end or portion located outside the patient's body.

[0036] The terms “tubular,” “tubular portion,” “tubular cavity,” etc., used herein are not intended to necessarily refer to a circular diameter or cross-section, although in certain embodiments they may refer to a circular diameter or cross-section. That is, other suitable geometries also fall within the scope of the terms used herein, such as square profiles or cross-sectional shapes, teardrop profiles or cross-sectional shapes, etc.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. Throughout the specification, approximations are referenced, such as by using the term “substantially.” For each such reference, it should be understood that in some embodiments, values, features, or characteristics may be specified without approximation. For example, in the use of qualifiers such as “about” and “substantially,” these terms, within their scope, include cases where the qualifier is absent. For example, in the use of the term “substantially straight” relative to a description of a feature, it should be understood that in other embodiments, the feature may have a precisely straight configuration.

[0038] Any method disclosed herein includes one or more steps or actions for performing the described method. These method steps and / or actions are interchangeable with each other. In other words, the order and / or use of a particular step and / or action may be modified unless proper operation of the embodiment requires a particular order of steps or actions. Furthermore, a subroutine or only a portion of the method described herein may be a separate method within the scope of the disclosed text. In other words, some methods may include only a portion of the steps described in the more detailed methods. Additionally, all embodiments disclosed herein are composable and / or interchangeable unless otherwise stated, or such combination or interchange would be contrary to the operability of any embodiment.

[0039] The disclosed text relates to a connectivity system for use in a medical environment in which it is desired to maintain a sterile environment near a patient's skin. The connectivity system includes a non-sterile instrument portion and a sterile device portion. The connectivity system also includes a sterile barrier separating the sterile environment from the non-sterile environment, wherein the instrument portion resides in the non-sterile environment and the sterile device portion resides in the sterile environment. An instrument connector is a component of the medical device, and a device connector is a component of the medical device. The medical device and medical device define a medical system. The medical device includes an elongated member configured for insertion into a patient's body, such as along the patient's vascular system. The medical system includes an end-effector positioning system configured to determine the location of a distal end of the elongated member within the patient's body.

[0060] The proximal portion 145 of the DC further defines a DC rib 431 projecting outward from the outer surface 416B of the circumferential wall 416 (i.e., generally the proximal portion 145 of the DC), wherein the DC rib 431 extends longitudinally along the proximal portion 145 of the DC. The DC rib 431 extends proximally away from the DC shoulder 446 toward the proximal end 141B. In the illustrated embodiment, the DC rib 431 extends substantially the entire length of the proximal portion 145 of the DC, i.e., from the DC shoulder 446 to the proximal end 141B. In other embodiments, the DC rib 431 extends only partially from the DC shoulder 446 toward the proximal end 141B.

[0061] DC 140 includes a Device Electrical Connector (DEC) 420 configured to electrically engage with EEC 220 when the connector system 100 arrangement is in a connected state. Although not specifically shown, DEC 420 is electrically connected to at least electrode 144A via one of one or more conductive elements of an elongated member 144. In the illustrated embodiment, DEC 420 extends along a DC recess 432 (included within the recess 432) between a DC cavity 415 and a DC shank cavity 445. The proximal portion of DEC 420 may be shaped to extend radially inward from the DC recess 432 and further in a distal direction within the DC cavity 415, thereby defining an angled contact surface 420A configured to electrically engage EEC 220 in the connected state. More specifically, the angled contact surface 420A is configured to deflect radially outward when engaging with EEC 220. DEC 420 is formed from any suitable conductive material, such as gold, brass, copper, or any combination thereof.

[0062] DC 140 also includes a device optical connector (DOC) 430 disposed within DC cavity 415. DOC 430 includes an optical connector protrusion 431 extending proximally from a closed distal end 415B into DC cavity 415. Optical connector protrusion 431 may extend along a central axis 417. Optical connector protrusion 431 includes a protrusion length 434 between approximately 50% and 70% of the length 414 of DC cavity 415. In some embodiments, optical connector protrusion 431 may define a male optical connector. DOC 430 may be directly coupled to optical fiber 144B of elongated member 144. The proximal end 430A of DOC 430 may be disposed distally inside open proximal end 415A to prevent clinicians from touching DOC 430, i.e., to prevent clinicians' fingers 205 from contacting DOC 430 and / or DEC 420.

[0063] Figure 5 This is a detailed cross-sectional side view of a portion of the connection system 100 in a fully connected state. A tubular member 310 is inserted into an EC cavity 215, which corresponds to a flange 320 disposed near the distal end 215B of the EC housing 111 of EC 110. An EC protrusion 221, together with an EOC 230 and an optical connector protrusion 231, extends distally into the tubular cavity 315 of the connection member 180. Ribs 331 are disposed within an EC recess 232 such that the connection member 180 is arranged for rotational alignment (i.e., bonding) relative to EC 110, and such alignment prevents rotation of the connection member 180 relative to EC 110.

[0064] The proximal DC portion 145 is inserted into the tubular cavity 315 to complete the connection between DC 140 and EC 110. The tubular cavity corresponds to the DC shoulder 446 disposed near the flange 320 of the connecting member 180. The EC protrusion 221, together with the EOC 230 and the optical connector protrusion 231, extends distally into the DC cavity 415 of the proximal DC portion 145. The DC rib 431 is disposed within the recess 332 such that the proximal DC portion 145 is arranged for rotational alignment relative to the connecting member 180, and such alignment prevents rotation of the proximal DC portion 145 relative to the connecting interface member 180. Therefore, the proximal DC portion 145 is rotationally aligned with EC 110, and rotation of the proximal DC portion 145 relative to EC 110 is prevented.

[0065] EC protrusion 221, together with EOC 230 and optical connector protrusion 231, extends distally into the DC cavity 415 of the connecting member 180. EEC 220, as part of EC protrusion 221, engages with the angled surface 420A of DEC 420 to complete the electrical connection between DC 140 and EC 110. Therefore, electrical connection 520 is established within (i) the DC cavity 415, (ii) the tubular cavity 315, and (iii) the EC cavity 215. By establishing electrical connection 520 within the DC cavity 415, tubular cavity 315, and EC cavity 215, electrical connection 520 is isolated from the environment, for example, protected from fluid contact, touch contact, or any other contamination.

[0066] The DOC 430, together with the optical connector protrusion 431, extends proximally into the protrusion cavity 222 to establish an optical connection with the EOC 230. Due to the bonding relationship between EC 110 and DC 140, the DOC 430 is positioned and maintained in rotational alignment with the EOC 230. The optical connector protrusion 431 is inserted through the alignment opening 226 to ensure lateral alignment of the DOC 430 and the EOC 230. Therefore, the alignment opening 226 is configured to define a tight-tolerance sliding fit with the optical connector protrusion 431. When the optical connector protrusion 431 is positioned within the protrusion cavity 222, an optical connection 530 is established within (i) the protrusion cavity 222, (ii) the DC cavity 415, (iii) the tubular cavity 315, and (iv) the EC cavity 215. Optical connections 530 are established within protrusion cavity 222, DC cavity 415, tubular cavity 315 and EC cavity 215. Optical connections 520 are isolated from the environment, for example, protected from fluid contact, touch contact or any other contamination.

[0067] In some embodiments, the connection system 100 may include a locking mechanism 540 configured to maintain the connection system 100 in a connected state and / or provide tactile feedback during connection. The locking mechanism 540 includes a first portion and a corresponding second portion, wherein the locking mechanism is configured to at least (i) provide tactile feedback to the user / clinician when the DC is connected to the EC or (ii) secure the DC to the EC in the connected state. In the illustrated embodiment, the locking mechanism 540 includes a locking protrusion 541 and a corresponding locking recess 542 arranged to interfere with the locking protrusion 541. In the illustrated embodiment, the locking protrusion 541 extends radially inward from the inner surface 416A of the circumferential wall 416 of the proximal portion 145 of the DC, and the locking recess 542 extends radially inward from the outer surface of the EC protrusion 221. The locking protrusion 541 and locking recess 542 are arranged such that when DC 140 is fully connected to EC 110, the locking protrusion 541 is positioned within the locking recess 542. Therefore, during insertion of the proximal portion 145 of DC into EC cavity 215, the locking protrusion 541 engages with the locking recess 542, providing tactile feedback. Similarly, the arrangement of the locking protrusion 541 within the locking recess 542 requires a separating force to disconnect DC 140 from EC 110. As will be understood by those skilled in the art, locking features other than the locking protrusion 541 and locking recess 542 can be incorporated into the connection system 100 to define the functionality of the locking mechanism 540.

[0068] Figure 6 This is a block diagram of a method for establishing a connection between a non-sterile medical device and a sterile medical device across a sterile barrier. The method may include all or any subset of the following steps, actions, or processes. Method 600 may include positioning a device connector of the non-sterile medical device relative to a sterile barrier such that the device connector is located on the non-sterile side of the sterile barrier (box 610). The sterile barrier separates a sterile environment from a non-sterile environment and includes a connection interface member attached to the sterile barrier on its non-sterile side. Method 600 further includes positioning the device connector of the medical device on the sterile side of the sterile barrier opposite the non-sterile side (box 620) such that the device connector is arranged together with the sterile environment. Method 600 further includes inserting a proximal portion of the device connector into an aperture through the sterile barrier (box 630), wherein the aperture extends from the sterile side through the sterile barrier to the non-sterile side. Inserting the proximal portion of the device connector further includes inserting the proximal portion into a tubular portion of the connection interface member, wherein the tubular portion extends away from the non-sterile side. Method 600 further includes inserting the proximal portion of the device and the tubular portion of the sterile barrier into the instrument connector cavity (frame 640) of the instrument connector to operatively connect the device connector to the instrument connector.

[0069] Method 600 may include, as part of operably connecting the device connector to the instrument connector, establishing at least one of an electrical connection or an optical connection between the device connector and the instrument connector. Method 600 may further include, as part of operably connecting the device connector to the instrument connector, establishing both an electrical connection and an optical connection between the device connector and the instrument connector.

[0070] According to method 600, the instrument connector may include an instrument connector protrusion extending distally into the instrument connector cavity from a closed proximal end, and the device connector may include a device connector cavity having an open proximal end and a closed distal end. Therefore, inserting the proximal portion of the device connector may include inserting the instrument connector protrusion into the device connector cavity.

[0071] According to method 600, the tubular portion may include ribs extending outward from the outer surface of the tubular portion and longitudinally extending along the outer surface of the tubular portion, and the instrument cavity may include an instrument recess extending outward from the inner surface of the instrument cavity and longitudinally extending along the inner surface of the instrument cavity. Therefore, inserting the tubular portion into the instrument connector cavity may include inserting the ribs into the instrument recess such that the tubular portion is arranged to be rotatably aligned with the instrument connector.

[0072] According to method 600, the proximal portion may include a device rib extending outward from the outer surface of the proximal portion and longitudinally along the outer surface of the proximal portion, and the tubular portion may include a groove extending outward from the inner surface of the tubular portion and longitudinally along the inner surface of the tubular portion. Therefore, inserting the proximal portion into the tubular portion may include inserting the device rib into the groove, such that the proximal portion is arranged to be rotatably aligned with the tubular portion.

[0073] According to method 600, the device cavity may include a device recess extending outward from and longitudinally along the inner surface of the device cavity, and the device connector may include a device electrical connector disposed within and extending along the device recess. Further according to method 600, the outer surface of the instrument connector protrusion may include the instrument electrical connector. Therefore, establishing an electrical connection may include making the device electrical connector and the instrument electrical connector electrically contact each other. Thus, an electrical connection can be established within the tubular portion, the instrument connector cavity, and the device connector cavity.

[0074] According to method 600, the electrical connector protrusion may include a protrusion cavity having an open distal end and a closed proximal end, and a medical device optical connector disposed at the distal end of the medical device connector protrusion, wherein the medical device connector protrusion extends distally into the protrusion cavity from the closed proximal end. Further according to method 600, the device connector may include a device optical connector located at the proximal end of the device connector protrusion, wherein the device connector protrusion extends proximally into the device connector cavity from the closed proximal end. Therefore, inserting the proximal portion into the medical device connector cavity includes operatively engaging the device optical connector with the medical device optical connector to define an optical connection. Thus, the optical connection can be established within the tubular portion, the medical device connector cavity, the medical device connector cavity, and the protrusion cavity.

[0075] According to method 600, the instrument connector may include a first portion of a locking mechanism disposed on the outer surface of an instrument connector protrusion, and a proximal portion of a corresponding second portion of the locking mechanism disposed on the inner surface of an instrument connector cavity. Therefore, inserting the proximal portion into the instrument connector cavity may include engaging the first portion with the second portion, such that the locking mechanism provides tactile feedback to the user / clinician.

[0079] The patient interface component 7710 is communicatively connected to the EC 7110, enabling electrical signals from the sensor 7730 to be transmitted to the medical device 7105. The patient interface component 7710 can be communicatively connected to the EC 7110 via a direct electrical connection. In some embodiments, the patient interface component 7710 can be communicatively connected to the medical device 7105 directly (i.e., without via the EC 7110).

[0080] SB 7170 includes a cover cloth 7171, which may be formed from woven fabric, non-woven fabric, plastic sheet, or any other suitable sheet material. SB 7170 is sterilized before use.

DC proximal portion 7145 is configured to be inserted, in the connected state, through a cover hole 7175 and into an EC opening 7115. Thus, cover hole 7175 is configured to receive DC proximal portion 7145 through which it passes, and EC opening 7115 is configured to receive DC proximal portion 7145 therein.

[0084] DC 7140 includes an elongated member 7144 extending distally away from the distal end. In some embodiments, the elongated member 7144 may include one or more conductive elements (e.g., wires, not shown) extending along the elongated member 7144, wherein these conductive elements may be configured to transmit, for example, ECG signals. In some embodiments, the elongated member 7144 may include components and functionality of the elongated member 144.

[0085] The connection system 700 includes an attachment mechanism 7182 configured to attach the connection interface member 7180 to the patient interface member 7710 and allow detachment of the connection interface member 7180 from the patient interface member 7710. As shown, the attachment mechanism 7182 can secure the EC 7110 to the patient interface member 7710. In some embodiments, the attachment mechanism 7182 may include a pair of deflectable members 7182A, for example, one deflectable member on each side of the connection interface member 7180. Each deflectable member 7182A includes a locking protrusion 7182C. The attachment mechanism 7182 includes a corresponding pair of locking recesses (or openings) 7182B in a frame 7720. Each locking recess 7182B is configured to receive the locking protrusion 7182C therein when the connection interface member 7180 is engaged with the patient interface member 7710. Therefore, the attachment mechanism 7182 secures the connection interface component 7180 to the patient interface component 7710.

[0086] The connection interface member 7180 includes a tubular member 7310 defining a tubular cavity 7315, and when DC 7140 is coupled to EC 7110, the proximal portion 7145 of DC is inserted into the tubular cavity 7315.
