Description

FIELD OF THE TECHNOLOGY

[0001] The field of the present application relates to medical devices, and more particularly, to embolization devices and delivery systems for delivering embolization devices. BACKGROUND OF THE INVENTION

[0002] An aneurysm is a blood vessel dilation that can lead to rupture, blood clotting, or dissection, posing a risk to health. Rupture of a cerebral aneurysm can cause a stroke, and rupture of an abdominal aneurysm can cause shock. Cerebral aneurysms are typically detected in patients due to seizures or bleeding, and cerebral aneurysms can lead to a relatively high morbidity or mortality rate.

[0003] A variety of materials and devices have been used to treat aneurysms, including platinum and stainless steel microcoils, polyvinyl alcohol sponges (Ivalone), and other mechanical devices. For example, an embolization (or vascular occlusion) device is a surgical instrument or implant that is typically placed within the vascular system of a human body through a catheter to block blood flow through the blood vessels that make up that portion of the vascular system by the formation of an embolus, or to form such an embolus within an aneurysm originating from that blood vessel.

[0004] Embolization devices or implants are used for a variety of reasons (including the treatment of intracranial aneurysms). Commonly used embolization devices include soft, helically wound coils formed by winding strands of platinum (or platinum alloy) wire around a "primary" mandrel. The coil is then wound around a larger "secondary" mandrel and heat treated to impart the secondary shape. For example, U.S. Patent No. 4,994,069 issued to Ritchart et al. (which is hereby incorporated by reference in its entirety as if fully set forth herein) describes a vascular occlusion device that assumes a linear, helical primary shape when stretched to be placed through the lumen of a delivery catheter and a folded, coiled secondary shape when released from the delivery catheter and placed in the vasculature.

[0005] To deliver an embolization device to a desired location within the vasculature (e.g., within an aneurysm sac), it is well known to first position a small-profile delivery catheter or "microcatheter" at that location using a steerable guidewire. Typically, the distal end of the microcatheter is provided by the attending physician or manufacturer with a selected preformed bend (e.g., 45°, 26°, "J-shaped", "S-shaped") or other curved shape, depending on the particular anatomy of the patient, such that once the guidewire is withdrawn, the distal end of the microcatheter will remain in the desired position to release one or more embolization devices into the aneurysm. A delivery or "pusher" assembly is then passed through the microcatheter until the embolization device secured to the distal end of the pusher assembly extends out of the distal opening of the microcatheter and into the aneurysm. The proximal end of the embolization device is typically secured to the distal end of the pusher assembly with an adhesive at a so-called "primary engagement" of the embolization device delivery assembly.

[0006] Another embolization device delivery assembly primary engagement portion design is disclosed in U.S. Patent No. 8,202,292 issued to Kellett, which is hereby incorporated by reference in its entirety as if fully set forth herein. The primary engagement portion includes a flat adapter that connects a delivery wire to an embolization (vascular occlusion) coil. The delivery wire has a hooked or "J" shaped distal end that is configured to be received in a hole in the proximal end of the adapter to attach the delivery wire to the adapter. The embolization coil has windings that define an opening that is configured to receive fingers in the distal end of the adapter to attach the embolization coil to the adapter. Thus, the adapter facilitates attaching the delivery wire to the embolization coil.

[0007] After the embolization device is delivered into an aneurysm, the embolization device is then released or "detached" from the end of the pusher assembly, typically by disassembling the distal end of the pusher assembly. The pusher assembly is then withdrawn through the catheter. One or more additional occlusion devices can be pushed through the catheter and released at the same site, depending on the specific needs of the patient.

[0008] A well-known way to release an embolization device from the end of a pusher assembly is by using an electrolysable separation joint, which is a small exposed section or disassembly zone located along the distal portion of the pusher assembly. The disassembly zone is typically made of stainless steel and is positioned just proximal to the embolization device. When the pusher assembly is charged in the presence of an ionic solution such as blood or other body fluid, the electrolysable separation joint is susceptible to electrolysis and disintegrates. Thus, once the disassembly zone exits the distal end of the catheter and is exposed in the patient's vascular blood pool, the current applied to the conductive pusher through the electrical contacts completes an electrolytic disassembly circuit with a return electrode, and the disassembly zone disintegrates due to electrolysis. Other disassembly mechanisms for releasing an embolization device from a pusher assembly include mechanical, thermal, and hydraulic mechanisms.

[0009] Although the primary engagement portions fixed with adhesives and those including flat adapters perform well, the connection between the delivery wire, the embolization coil, and the adapter can be improved. Thus, there is still a need for other systems and methods for fixing an embolization device to a pusher assembly at the primary engagement portion. Overview

[0053] Various embodiments are described below with reference to the accompanying drawings. It should be noted that the drawings are not drawn to scale, and in all the drawings, elements of similar structure or function are denoted by the same reference numerals. It should also be noted that these figures are only intended to facilitate the description of the embodiments. They are not intended as an exhaustive description of the present invention or a limitation on the scope of the present invention. In addition, the illustrated embodiments do not necessarily have all the aspects or advantages shown. Aspects or advantages described in connection with a particular embodiment are not necessarily limited to that embodiment and may be practiced in any other embodiment even if not so illustrated or not so explicitly described.

[0054] Figure 1 Illustrates a medical device 10 having a catheter 20 for delivering an embolization device 100 into a body cavity. The catheter 20 has a distal end 22, a proximal end 24, and a catheter body 26 extending between the distal end 22 and the proximal end 24. The embolization device 100 is received within a lumen 28 of the catheter 20. The catheter 20 further includes a delivery wire (e.g., a shaft) 30 located within the lumen 28 for pushing the embolization device 100 out of the lumen 28 of the catheter 20.

[0055] As Figure 1 shown, the embolization device 100 is made of an elongate member 102 having a distal end 104, a proximal end 106, and a body 108 extending between the distal end 104 and the proximal end 106. The embolization device 100 has a first section 110 that has a first linear configuration when located within the catheter 20. The first section 110 is configured to form a first three-dimensional structure 112 when the first section 110 is delivered outside the catheter 20 ( Figure 2A ).

[0056] Also as Figure 1 shown, the embolization device 100 has a second section 120 extending from the first section 110. The second section 120 is proximal to the first section 110. The second section 120 has a second linear configuration when located within the catheter 20. The second section 120 is configured to form a second three-dimensional structure 122 when the second section 120 is delivered outside the catheter 20 ( Figure 2B). In some embodiments, the first segment 110 and the segment 120 can be part of a single structure formed to have the first segment 110 and the second segment 120. In other embodiments, the first segment 110 and the second segment 120 can be separate components connected together, for example, via adhesives, welding, fusing, mechanical connectors, etc. In either case, the first segment 110 and the second segment 120 can be considered to have or form an overall configuration. In other cases, the embolization device 100 can have only one segment or more than two segments.

[0057] As Figure 2A shown, after the first segment 110 forming the first three-dimensional structure 112 is delivered out of the catheter 20, the first three-dimensional structure 112 defines a chamber 118. Thus, after the first segment 110 has been delivered from the catheter 20 into the body cavity, the first three-dimensional structure 112 provides the chamber 118 for accommodating the remainder of the embolization device 100 (e.g., at least most of the second segment 120 forming the second three-dimensional structure 122).

[0058] In other cases, the segments 110, 120 of the embolization device 100 may not form the corresponding three-dimensional structures 112, 122 in a nested configuration. Instead, the embolization device 100 can have one or more segments forming multiple rings, where the rings form a three-dimensional structure to occupy the chamber of the aneurysm. In additional cases, the embolization device 100 can be any implant capable of forming a three-dimensional structure for occupying the body cavity.

[0059] Figures 3A - 3B Illustrated is a method of treating an aneurysm 700 using a Figure 1 medical device 10. When using the medical device 10, the catheter 20 is first inserted through an incision into the patient's blood vessel 702. Then the catheter 20 is advanced distally until the distal end 22 of the catheter 20 is located at the aneurysm.

[0060] In some embodiments, the catheter 20 can be steerable. For example, the catheter 20 can include one or more steering wires configured to steer the distal end 22 of the catheter 20 in one or more directions. In other embodiments, the catheter 20 may not be steerable. Instead, a guide wire can be first used to approach the target site. Then, the catheter 20 can be disposed on the guide wire and advanced distally using the guide wire. In this case, the catheter 20 can include a separate channel for accommodating the guide wire.

[0061] After the distal end 22 of the catheter 20 is ideally positioned, then the shaft 30 (shown in Figure 1 is advanced to push the embolization device 100 distally until the first segment 110 of the embolization device 100 is outside the catheter 20 ( Figure 3A). As shown, when the first segment 110 is unrestricted outside the catheter 20, the first segment 110 forms a first three-dimensional structure 112. The first three-dimensional structure 112 has a shape corresponding to the inner wall of the aneurysm such that the first three-dimensional structure 112 is positioned adjacent to the wall of the aneurysm (e.g., against the wall of the aneurysm or within 0.5 mm of the wall of the aneurysm). The first three-dimensional structure 112 (schematically represented by the dashed line in Figure 7 A) provides a framework defining a chamber 118 for receiving the second segment 120 of the embolization device 100. As shown, the first three-dimensional structure 112 also provides a stent across the neck 704 of the aneurysm 700 that facilitates receiving the second-dimensional structure 122 to be delivered into the chamber 118.

[0062] Next, the shaft 30 can be further advanced to push the second segment 120 of the embolization device 100 until the second segment 120 exits the catheter 20 ( Figure 3B ). As shown, when the second segment 120 is unrestricted outside the catheter 20, the second segment 120 forms a second three-dimensional structure 122. The second three-dimensional structure 122 has a shape that allows it to fill at least some of the space in the chamber 118 defined by the first three-dimensional structure 112. As shown, the stent across the neck 704 of the aneurysm provided by the first three-dimensional structure 112 prevents the second-dimensional structure 122 from escaping or detaching from the chamber 118 of the first three-dimensional structure 112 and the aneurysm.

[0063] In other cases, the embolization device 100 may not be configured to form multiple three-dimensional structures in a nested configuration. In such cases, when the shaft 30 is advanced to push the embolization device 100 out of the catheter 20, the embolization device 100 may form one or more three-dimensional structures that fill the chamber of the aneurysm in a non-nested configuration. For example, one or more three-dimensional structures formed by the embolization device 100 may fill the aneurysm cavity from the distal end of the aneurysm towards the proximal end of the aneurysm, or may fill the aneurysm cavity in a random configuration.

[0064] In some embodiments, the distal end of the shaft 30 may be mechanically connected to the proximal end of the second segment 100 via a decomposable linkage, such as a linkage that decomposes in response to the application of an electric current.

[0065] In some embodiments, multiple embolization devices 100 may be provided with different respective lengths. In such cases, before selecting one of the embolization devices 100 for treating an aneurysm, a doctor may measure the size of the aneurysm to be treated. For example, the doctor may perform measurements using one or more images of the aneurysm to determine the size of the aneurysm. The size may be the cross-sectional dimension of the aneurysm, the cross-sectional area of the aneurysm, the volume of the aneurysm, etc. After the size of the aneurysm has been determined, one of the embolization devices 100 may then be selected based on the size of the aneurysm. For example, a longer embolization device 100 may be selected to occlude a larger aneurysm.

[0066] Figure 4 illustrates an Figure 1 example of an embolization device. The embolization device 100 is a braided structure made of multiple braided wires. The embolization device 100 is removably coupled to a portion of the delivery wire 30 via a junction 400. In some cases, the embolization device 100 may optionally include coils coupled between the braided wires of the braided structure and the delivery wire 30. In other cases, the embolization device 100 may not include such coils. In additional cases, the embolization device 100 may not include a braided structure. Alternatively, the embolization device 100 may have coils configured to form a three-dimensional structure for occupying an aneurysm. Additionally, in some cases, the junction 400 may be considered a part of the delivery wire 30 and / or may be formed of the same material as the delivery wire 30.

[0067] In different embodiments, the delivery wire 30 may be coupled to the embolization device 100 using different techniques. For example, in some cases, the embolization device 100 may include components that connect the braided wires of the embolization device 100 to the delivery wire 30.

[0068] Figure 5 and Figures 6A - 6C illustrates an Figure 1 example of components 500 of the embolization device 100. The components 500, which may be considered examples of medical devices, are configured to interface between the braided wires of the embolization device 100 and the delivery wire 30. The components 500 include a socket 502 having one or more sidewalls 510 that define a chamber 520 sized to receive multiple braided wires 530. The socket 502 also has an end wall 540 coupled to and / or extending from the one or more sidewalls 510. The socket 502 also has a first anchor 580a on an inner surface of the one or more sidewalls 510 of the socket 502. The first anchor 580a is configured to press against at least one of the braided wires 530 after the socket 502 has received the braided wires 530.

[0069] In the illustrated example, receptacle 502 has two side walls 510 that define a chamber 520 for receiving braided wire 530. In other cases, receptacle 502 may have more than two side walls 510 that define chamber 520. In another example, one or more side walls 510 may include only a single circumferential side wall 510 that defines chamber 520.

[0070] In some cases, braided wire 530 may be inserted into chamber 520 of receptacle 502 with an insertion force Fi, and receptacle 502 is configured to grip braided wire 530 such that receptacle 502 can resist a removal force Fr to prevent braided wire 530 from being removed from the receptacle. In some cases, removal force Fr may be higher than insertion force Fi.

[0071] Optionally, component 500 may further include one or more additional anchors 580 (e.g., anchor 580b and / or anchor 580c), wherein first anchor 580a and the one or more additional anchors are configured to allow braided wire 530 to be inserted into receptacle 502 with an insertion force and resist a removal force to prevent braided wire 530 from being removed from receptacle 502. In some cases, the removal force may be higher than the insertion force.

[0072] As Figure 5 and Figure 6C shown, anchors 580a - 580c are oriented in a row in a direction parallel to the longitudinal axis of receptacle 502. In other cases, anchors 580a - 580c may be aligned in a row that is not parallel to the longitudinal axis of receptacle 502. Additionally, in other cases, anchors 580a - 580c may not be aligned in a row (e.g., a straight row). Instead, anchors 580a - 580c may have a staggered configuration. Additionally, in other cases, receptacle 502 may have more than three anchors 502, or fewer than three anchors 502. For example, in other cases, receptacle 502 may have two anchors 502 or only a single anchor 502 (e.g., first anchor 502a).

[0073] In some cases, first anchor 580a, second anchor 580b, or third anchor 580c may include struts or barbs. However, anchors 580a - 580c should not be limited to these examples. In other cases, each of anchors 580a - 580c may be any structural component that allows braided wire 530 to be inserted into chamber 520 of receptacle 502 while contributing to resisting a removal force applied to pull braided wire 530.

[0074] The braided wire 530 is part of the braided structure of the embolization device 100. The braided structure of the embolization device is sized for insertion into an aneurysm. In some cases, the braided wire 530 can include at least three braided wires. In other cases, the braided wire 530 can include more than three braided wires or less than three braided wires. For example, in other cases, the braided wire 530 can include 4, 5, 6, 7, 8, 9, 10, 11, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30 braided wires.

[0075] As Figure 5 and Figures 6A - 6C shown, the component 500 further includes a ring 590 coupled to the end wall 540 of the socket 502. The ring 590 defines a ring opening 592 that is sized to receive the distal portion 602 of the delivery wire 30. The distal portion 602 of the delivery wire 30 has a curved structure and is anchored to the ring 590 when the distal portion 602 is received within the ring opening 592. As shown in the figure, the ring 590 and the chamber 520 are on opposite respective sides of the end wall 540.

[0076] In some cases, the socket 502 and the ring 590 can be formed together during the manufacturing process. For example, the socket 502 and the ring 590 can be formed together via a molding process or a printing process. Alternatively, the socket 502 and the ring 590 can be formed separately and then connected to each other via an adhesive.

[0077] The socket 502 and the ring 590 can be made of the same material or different respective materials. For example, the socket 502 and / or the ring 590 can be made of a polymer, a metal, or an alloy (such as HTL, biopolymer, palladium, etc.). In some cases, the socket 502 and / or the ring 590 can be made of a biocompatible material or a 3D printing material. Figure 7 Illustrated is Figure 5 a variant of the component 500, particularly showing the component 500 made of a polymer. Figure 7 Illustrated is Figure 5 another variant of the component 500, particularly showing the component 500 made of a metal.

[0078] In some cases, the delivery wire 30 or at least the distal portion 602 of the delivery wire 30 can be considered part of the component 500. The distal portion 602 of the delivery wire 30 is connected to the remainder of the delivery wire 30 via a detachable link 400. In some cases, the detachable link 400 can also be considered part of the component 500. In other cases, the distal portion 602 and / or the detachable link 400 are not part of the component 500.

[0079] In addition, in some cases, the component 500 may optionally include a braided wire 530. In such cases, the braided wire 530 is part of the component 500. In other cases, the braided wire 530 is not part of the component 500. Because the braided wire 530 is part of the braided structure forming the embolization device 100, in some cases, the component 500 may optionally include the braided structure or the embolization device 100.

[0080] In some cases, the (one or more) side walls 510 and the end wall 540 of the socket 502 may be integrally formed together such that they have an integral or one-piece configuration. In addition, in some cases, the ring 590 may also be integrally formed with the end wall 540 and the (one or more) side walls 510 such that they have an integral or one-piece configuration. In other cases, the (one or more) side walls 510, the end wall 540, the ring 590, or any combination of the foregoing may be formed separately and may be fixed to each other via an adhesive.

[0081] In addition, in some cases, the component 500 may optionally further include an adhesive connecting the socket 502 and the braided wire 530. The adhesive may be disposed between the (one or more) walls 510 of the socket 502 and the braided wire 530. Alternatively, the adhesive may be a blob surrounding the ends of the socket 502 and the braided wire 530.

[0082] As described above, the component 500 may be considered a medical device. The medical device may include only the socket 502 and the ring 590. Alternatively, the medical device may optionally include the braided wire 530, the braided structure formed by the braided wire 530, the embolization device including the braided structure, the distal portion 602 of the delivery wire 30, the delivery wire 30, the detachable link 400, or any combination of the foregoing. Thus, as used in this specification, the term "medical device" is not limited to a finished or completed commercial product and may refer to one or more components of a product.

[0083] It should be noted that the component / medical device 500 is advantageous because it provides a structural interface that connects the braided wire 530 to the distal portion 602 of the delivery wire 30. The component / medical device 500 eliminates any need to use a coil as an interface between the braided wire 530 and the delivery wire 30. In addition, the component / medical device 500 allows the braided wire 530 to be easily and effectively connected to the delivery wire 30 via a few simple steps. In one example, the braided wire 530 can be inserted into the chamber 520 of the socket 502. (One or more) anchors 580 at (one or more) inner walls of the socket 502 help to fix the braided wire 530 relative to the socket 502. Optionally, an adhesive can be applied to enhance the fixation between the braided wire 530 and the socket 502. Then, the distal portion 602 of the delivery wire 30 can be inserted into the ring opening 592 of the ring 590 and can be anchored on the ring 590. In some cases, the adhesive can be applied after the distal portion 602 of the delivery wire 30 is anchored to the ring 590. The adhesive may be a mass that surrounds or encloses the hub 502, the ring 590, a portion of the braided wire 530, a portion of the distal portion 602 of the delivery wire 30, any combination of the foregoing, or all of the foregoing.

[0084] It should be noted that component 500 is not limited to having the configuration shown in the above examples, and in other cases, component 500 may have other configurations. For example, in other cases, ring 590 may have a thicker configuration and may have the same width as end wall 540. Furthermore, in other cases, end wall 540 may not have a planar configuration similar to that shown in the above examples, and may instead have a block-like configuration. Therefore, as used in this specification, the term "wall" is not limited to a structure having a thin planar configuration, and may cover structures having other shapes, and / or may cover any structure between two spaces.

[0085] On top Figure 5 In the example of FIG. 5 , the component 500 is specifically configured to be coupled to an embolic device 100 having a braided wire 530 and without any coils coupled to the proximal end of the braided wire 530. In other cases, the embolic device 100 may have a coil coupled to the proximal end of the braided wire 530. In such a case, a component that interfaces between the coil and the delivery wire 30 may be provided.

[0086] Figure 9 , Figure 10A and Figure 10B Pictured Figure 1Another example of component 900 of embolization device 100. Component 900, which can be considered an example of a medical device, is configured to dock between the coils (if the embolization device 100 includes coils) of the embolization device 100 and the delivery wire 30. Component 900 includes a rod 910 sized to be inserted into the lumen 922 of the coil 920. Component 900 further includes a stop 950 coupled to and / or extending from the rod 910, where the stop 950 is adjacent to the proximal end 924 of the coil 920 when the rod 910 is inserted into the lumen 922 of the coil 920. The stop 950 is configured to prevent the rod 910 from being inserted too deeply into the lumen 922 of the coil 920. The stop 950 may have a surface configured to abut the end loop of the coil 920 at the proximal end 924 of the coil 920. Alternatively, the stop 950 may not abut the end loop of the coil 920. Instead, the stop 950 may be spaced from the end loop or may be indirectly coupled to the end loop via another structural component (such as a disk, adhesive, etc.). Component 900 further includes a structure 932 located outside the lumen 922 of the coil 920. The structure 932 is adjacent to the rod 910 and the stop 950. The structure 932 defines an opening 934 sized to receive the distal portion 602 of the delivery wire 30. The rod 910 includes a channel 960 configured to receive the first portion 972 of the tensile member 970 when the second portion 974 of the tensile member 970 is disposed around the structure 932 that defines the opening 934.

[0087] In the example shown, component 900 has one channel 960 to receive the first portion 972 of the tensile member 970, and the tensile member 970 forms a hook that terminates at ends 1442 / 1444 that are closer to the proximal end 924 of the coil 920 than to the distal end 926 of the coil 920 (as Figure 10A and Figure 14A shown). The tensile member 970 may extend to the distal end 926 of the coil 920, form a loop there, and then extend back to the proximal end 924 of the coil 920. In this case, the two opposite ends 1442, 1444 of the tensile member 970 are positioned closer to the proximal end 924 of the coil 920 than to the distal end 926 of the coil 920 (as Figure 10A and Figure 14A shown).

[0088] In other cases, the tensile member 970 forms a loop 1446 around the structure 932 and may extend back towards the distal end 926 of the coil 920 (as Figure 14BAs shown). In such a case, the component 900 may optionally include, at the stem 910, a second channel for receiving another segment (return portion) of the tensile member 970. Alternatively, the same channel 960 may accommodate two segments of the tensile member 970. As another alternative, the return segment of the tensile member 970 may be accommodated between the outer surface of the stem 910 and the inner surface of the coil 920.

[0089] Figure 10A A perspective view of a portion of the component 900 is shown. Figure 10B is Figure 10A A perspective view of the component 900, particularly showing the coil 920, the tensile member 970, and the guide wire 30 coupled thereto.

[0090] As Figures 10A - 10B shown, the component 900 may optionally further include a cover 980 that covers at least a portion of the tensile member 970 disposed around the structure 932. The cover 980 may provide some protection for the tensile member 970.

[0091] In some cases, the stem 910 and the structure 930 may be integrally formed together such that they have a unitary or single-piece configuration. Additionally, in some cases, the stop 950 may also be integrally formed with the stem 910 and the structure 930 such that they have a unitary or single-piece configuration. If the component 900 includes a cover 980. The cover 980 may also be integrally formed with the stem 910 and / or the stop 950 such that they have a unitary or single-piece configuration. In other cases, the stem 910, the stop 950, the structure 932, the cover 980, or any combination of the foregoing may be formed separately and may be fixed to each other via an adhesive.

[0092] During the manufacturing process, the stem 910 of the component 900 may be inserted into the lumen 922 of the coil 920. Then, the tensile member 970 may be inserted into the channel 960 of the stem 910. The tensile member 970 is guided around the structure 932 to form an anchor (e.g., a hook). Next, the distal portion 602 of the delivery wire 30 may be inserted into the opening 934 defined by the structure 932 and anchored to the component 900. In another variant, the tensile member 970 may first be inserted into the channel 960 of the stem 910 and guided around the structure 932 to form an anchor, i.e., before the stem 910 of the component 900 is inserted into the lumen 922 of the coil 920. Optionally, an adhesive may be applied to fix the component 900 to the coil 920, thereby fixing the tensile member 970 to the component 900, fixing the distal portion 602 of the delivery wire 30 to the component 900, or any combination of the foregoing. In one embodiment, an adhesive mass may be disposed around the structure 932, the stop 950, and the proximal end 924 of the coil 920.

[0093] The rod 910, the stopper 950, and the structure 932 may be made of the same material or different respective materials. For example, the rod 910, the stopper 950, the structure 932, or any combination of the foregoing may be made of a polymer, metal, or alloy (such as HTL, biopolymer, palladium, etc.). In some cases, the stopper 950, the structure 932, or any combination of the foregoing may be made of a biocompatible material or a 3D printing material.

[0094] In some cases, the delivery wire 30 or at least the distal portion 602 of the delivery wire 30 may be considered part of the component 900. The distal portion 602 of the delivery wire 30 is connected to the remainder of the delivery wire 30 via a detachable link 400. In some cases, the detachable link 400 may also be considered part of the component 900. In other cases, the distal portion 602 and / or the detachable link 400 are not part of the component 900.

[0095] In addition, in some cases, the tensile member 970 may be considered part of the component 900. In this case, the component 900 further includes the tensile member 970. In other cases, the component 900 does not include the tensile member 970.

[0096] In addition, in some cases, the component 900 may optionally include a coil 920. In this case, the coil 920 is part of the component 900. In other cases, the coil 920 is not part of the component 900.

[0097] Optionally, the component 900 may further optionally include a braided structure (formed by braided wires) coupled to the coil 920. The braided structure may be part of the embolization device 100, and the braided structure may be sized for insertion into an aneurysm. Thus, in some cases, the component 900 may optionally include the embolization device 100. In other cases, the braided structure is not part of the component 900. In additional cases, the coil 920 itself may be the embolization device 100. In this case, the component 900 does not include any braided structure.

[0098] As described above, the component 900 may be considered a medical device. The medical device may include only the rod 920, the stopper 950, and the structure 932. Alternatively, the medical device may optionally include the tensile member 970, the coil 920, a braided structure (formed by braided wires) coupled to the coil 920, an embolization device including the braided structure and the coil 920, the distal portion 602 of the delivery wire 30, the delivery wire 30, the detachable link 400, or any combination of the foregoing.

[0099] It should be noted that the component / medical device 900 is advantageous as it provides a structural docking for connecting the coil 920 to the distal portion 602 of the delivery wire 30. Additionally, the component / medical device 900 allows the coil 920 to be easily and effectively connected to the delivery wire 30 via several simple steps. Further, since the distal portion 602 of the delivery wire 30 and the anti-tensile member 970 are anchored to the same structure 932, the distal portion 602 of the delivery wire 30 and the anti-tensile member 970 are indirectly anchored to each other via the structure 932. This is advantageous because the anchoring strength between the anti-tensile member 970 and the delivery wire 30 does not depend on the structural strength (e.g., tensile strength) of the structure 932. In particular, as Figure 10A shown, the distal portion 602 of the delivery wire 30 is anchored on the inner surface of the structure defining the opening 934, while the anti-tensile member 970 is anchored on the outer surface of the structure 932. Thus, the distal portion 602 of the delivery wire 30 and the anti-tensile member are anchored on opposite surfaces of the structure 932. Accordingly, even if the structure 932 is damaged, the anti-tensile member 970 and the distal portion 602 of the delivery wire 30 will still be anchored to each other.

[0100] It should be noted that the component 900 should not be limited to having the Figure 9 configuration shown, and the component 900 may have other configurations in other cases. Figures 11A - 11E Illustrated is Figure 9 a variant of the component. As Figure 11A shown, the rod 910 may have a smooth edge or a rounded surface finish. As Figure 11B shown, the first portion 912 of the rod 910 may include threads 1120 that are configured to allow the first portion 912 of the rod 910 to be screwed into the opening 922 of the coil 920. Additionally, the opening 934 defined by the structure 932 may have a non-circular shape, such as an oval shape. As Figure 11C shown, in some cases, the stop 950 may not be a flange and may be any enlarged portion capable of preventing the rod 910 from being inserted too deeply into the lumen 922 of the coil 920. Figure 11D Illustrated is Figure 9 the component 900, particularly showing the component 900 having a finished external surface finish. Figure 11E Illustrated is the component 900 having the same configuration as Figure 11D shown, except that the component 900 is made by a printing process, where the component 900 has rough edges due to the printing process.

[0101] Figure 12 and Figures 13A - 13C Illustrated is Figure 1Another example of component 1200 of an embolization device. Component 1200, which can be considered an example of a medical device, is configured to dock between the coils (if the embolization device 100 includes coils) of the embolization device 100 and the delivery wire 30. Component 1200 includes a rod 1210 sized for insertion into the lumen 922 of the coil 920. Component 1200 also includes a stopper 1220 coupled to and / or extending from the rod 1210. When the rod 1210 is inserted into the lumen 922 of the coil 920, the stopper 1220 is adjacent to the proximal end 924 of the coil 920. Component 1200 also includes a ring 1240 adjacent to the stopper 1220. The ring 1240 defines a ring opening 1242 sized to receive the distal portion 602 of the delivery wire 30 and a portion 975 of the anti-tensile member 970.

[0102] Figure 12 Component 1200 is illustrated without the coil 920, the anti-tensile member 970, and the delivery wire 30. Figure 13A is Figure 12 A perspective view of component 1200, particularly showing the coil 920, the anti-tensile member 970, and the guide wire 30 coupled thereto.

[0103] As Figure 13B shown, the anti-tensile member 970 forms a hook terminating at ends 1442 / 1444 that are closer to the proximal end 924 of the coil 920 than to the distal end 926 of the coil 920 (as Figure 14A shown). The anti-tensile member 970 can extend to the distal end 926 of the coil 920, form a loop there, and then extend back to the proximal end 924 of the coil 920. In this case, the two opposite ends 1442, 1444 of the anti-tensile member 970 are positioned closer to the proximal end 924 of the coil 920 than to the distal end 926 of the coil 920 (as Figure 14A shown).

[0104] In other cases, the anti-tensile member 970 forms a loop 1446 around the rod 1210 and can extend back toward the distal end 926 of the coil 920 (as Figure 13C and Figure 14B shown).

[0105] As Figure 13B and Figure 13CAs shown, a portion of the anti-tensile member 970 is received on opposite sides of the rod 1210. Specifically, a first portion of the anti-tensile member 970 is received between the first side of the rod 1210 and the coil 920, and a second portion of the anti-tensile member 970 is received between the second side (opposite the first side) of the rod 1210 and the coil 920. In other cases, the rod 1210 may have one or more channels (defined on the outer surface of the rod 1210 or located inside the rod 1210) for receiving corresponding portions of the anti-tensile member 970.

[0106] In addition, as Figure 13B / Figure 13C shown, the rod 1210 may optionally include a recess 1280 for receiving another portion 1290 of the anti-tensile member 970. In other cases, the rod 1210 may not include the recess 1280.

[0107] In some cases, the rod 1210 and the stop 1220 may be integrally formed together such that they have a monolithic or single-piece configuration. In addition, in some cases, the ring 1240 may also be integrally formed with the rod 1210 and the stop 1220 such that they have a monolithic or single-piece configuration. In other cases, the rod 1210, the stop 1220, the ring 1240, or any combination of the foregoing may be formed separately and may be fixed to each other via an adhesive.

[0108] During the manufacturing process, the rod 1210 of the component 1200 may be inserted into the lumen 922 of the coil 920. Then, the anti-tensile member 920 may be inserted into the opening 1242 of the ring 1240 and wound around the rod 1210 (to form a hook) to anchor the anti-tensile member 920 to the rod 1210. Next, the distal portion 602 of the delivery wire 30 may be inserted into the opening 1242 of the ring 1240 and anchored to the component 1200. In another variant, before inserting the rod 1210 of the component 1200 into the lumen 922 of the coil 920, the anti-tensile member 970 may be inserted into the opening 1242 of the ring 1240 to anchor the anti-tensile member 970 around the rod 1210. Optionally, an adhesive may be applied to fix the component 1200 to the coil 920, thereby fixing the anti-tensile member 970 to the component 1200, fixing the distal portion 602 of the delivery wire 30 to the component 1200, or any combination of the foregoing. In one embodiment, an adhesive mass may be disposed around the ring 1240, the stop 1220, and the proximal end 924 of the coil 920.

[0109] Optionally, if the component 1200 includes a recess 1280 (shown in Figures 13A - 13B), after the anti-tensile member 970 has been anchored around the rod 1210 and the rod 1210 has been inserted into the lumen 922 of the coil 920, the proximal end 924 of the coil 920 can be crimped from the outside to press a portion 1290 of the anti-tensile member 970 into the recess 1280. This causes a bent or kinked portion of the portion 1290 of the anti-tensile member 970 to be anchored within the recess 1280, thereby further anchoring the anti-tensile member 970 to the rod 1210.

[0110] The rod 1210, the stopper 1220, and the ring 1240 can be made of the same material or different respective materials. For example, the rod 1210, the stopper 1220, the ring 1240, or any combination of the foregoing can be made of a polymer, a metal, or an alloy (such as HTL, biopolymer, palladium, etc.). In some cases, the rod 1210, the stopper 1220, the ring 1240, or any combination of the foregoing can be made of a biocompatible material or a 3D printing material.

[0111] In some cases, the delivery wire 30 or at least the distal portion 602 of the delivery wire 30 can be considered part of the component 1200. The distal portion 602 of the delivery wire 30 is connected to the remainder of the delivery wire 30 via a detachable link 400. In some cases, the detachable link 400 can also be considered part of the component 1200. In other cases, the distal portion 602 and / or the detachable link 400 are not part of the component 1200.

[0112] Furthermore, in some cases, the anti-tensile member 970 can be considered part of the component 1200. In this case, the component 1200 further includes the anti-tensile member 970. In other cases, the component 1200 does not include the anti-tensile member 970.

[0113] Furthermore, in some cases, the component 1200 can optionally include the coil 920. In this case, the coil 920 is part of the component 1200. In other cases, the coil 920 is not part of the component 1200.

[0114] Optionally, the component 1200 can also optionally include a braided structure (formed by braided wires) coupled to the coil 920. The braided structure can be part of the embolization device 100, and the braided structure can be sized for insertion into an aneurysm. Thus, in some cases, the component 1200 can optionally include the embolization device 100. In other cases, the braided structure is not part of the component 1200. In additional cases, the coil 920 itself can be the embolization device 100. In this case, the component 1200 does not include any braided structure.

[0115] As described above, the component 1200 may be considered a medical device. The medical device may include only the shaft 1210, the stop 1220, and the ring 1240. Alternatively, the medical device may optionally include a tensile member 970, a coil 920, a braided structure (formed of braided wires) coupled to the coil 920, an embolization device including the braided structure and the coil 920, a distal portion 602 of the delivery wire 30, the delivery wire 30, a detachable link 400, or any combination of the foregoing.

[0116] It should be noted that the component / medical device 1200 is advantageous because it provides a structural docking for connecting the coil 920 to the distal portion 602 of the delivery wire 30. In addition, the component / medical device 1200 allows the coil 920 to be easily and effectively connected to the delivery wire 30 via several simple steps. Further, since both the distal portion 602 of the delivery wire 30 and the tensile member 970 are inserted into the same opening 1242 of the ring 1240, the component 1200 does not require multiple different openings to separately accommodate the delivery wire 30 and the tensile member 970.

[0117] It should be noted that the component 1200 is not limited to having Figure 12 the illustrated configuration, and the component 1200 may have other configurations in other cases.

[0118] Figure 14A An example of a portion of the embolization device 100 is illustrated Figure 1 As shown, the embolization device 100 includes a coil 920 having a proximal end 924 and a distal end 926. The embolization device 100 further includes a braided structure 1400 coupled to the distal end 926 of the coil via a coupler 1400. In the illustrated example, the coupler 1400 includes a first coupler portion 1422 configured to be placed into the lumen of the coil 920 at the distal end 926 of the coil 920. The coupler 1400 further includes a second coupler portion 1424 that is larger than the first coupler portion 1422. The second coupler portion 1424 is a stop that prevents the first coupler portion 1422 from being inserted too deeply into the lumen of the coil 920. The coupler 1420 has an opening 1426 configured to receive and grip the braided wires of the braided structure 1400.

[0119] In the illustrated example, the anti-tensile member 970 has opposing ends 1442, 1444 that are closer to the proximal end 924 of the coil 920 than to the distal end 926 of the coil. In this case, the anti-tensile member 970 forms a loop 1446 that is closer to the distal end 926 of the coil 920 than to the proximal end 924 of the coil, and the loop is anchored distally. As shown, the loop 1446 formed by the anti-tensile member 970 extends through the braided wires of the braided structure 1400. The proximal ends of the braided wires are coupled to an end cap 1450 that prevents the loop 1446 of the anti-tensile member 970 from detaching from and / or moving proximally relative to the braided wires. Alternatively or additionally, an adhesive may be applied to secure the loop 1446 of the anti-tensile member 970 to the braided wires.

[0120] It should be noted that the coupler 1420 is not limited to having the illustrated configuration, and in other embodiments, the coupler 1420 may have other configurations. For example, in other cases, the first portion 1424 of the coupler 1420 may have a shape other than a tapered shape. Additionally, in other cases, the embolization device 100 may not require the end cap 1450. For example, in other cases, the proximal ends of the braided wires of the braided structure 1400 may form a knot that anchors the loop 1446 of the anti-tensile member 970. In other cases, the loop 1446 of the anti-tensile member 970 is not anchored to the braided wires. Instead, the loop 1446 of the anti-tensile member 970 may be anchored to the distal end 926 of the coil 920 and / or the coupler 1420.

[0121] Figure 14B An illustration of Figure 1 another example of a portion of the embolization device 100 is shown. The embolization device 100 is the same as Figure 14A except that the ends 1442, 1444 of the anti-tensile member 970 are closer to the distal end 926 of the coil 920 than to the proximal end 924 of the coil 920. In this case, the anti-tensile member 970 forms a loop 1446 that is closer to the proximal end 924 of the coil 920 than to the distal end 926 of the coil 920. In this case, the ends 1442, 1444 of the anti-tensile member 970 may be anchored to the coupler 1420, the distal end 926 of the coil, the proximal ends of the braided wires of the braided structure 1400, or any combination of the foregoing.
