摘要： Described here are systems, devices, and methods for delivery of an implant to a bodily cavity. The implant may include a hub and a plurality of legs, and may be moveable between a low-profile and expanded configuration. The systems may include a crimping device having a crimping member with a plurality of arms. The plurality of arms may engage the plurality of legs of the implant, and may move the legs to move the implant to the low-profile configuration. In some instances a delivery device may aid in crimping and/or delivery of the implant.

摘要： A method of using a self-adjusting stent assembly includes estimating body lumen diameter(s) associated with a portion of a body lumen in which a stent assembly will be placed; determining, based on the estimated diameter(s), target expanded stent diameter(s) of the stent assembly which is to be placed in the portion of the body lumen; selecting the stent assembly for stenting the portion of the body lumen, wherein the stent assembly is configured to: expand from an initial to expanded diameters within a range of expanded diameters; wherein the range of expanded diameters is from about 9 mm to about 5.5 mm; and wherein the target expanded stent diameter(s) is/are within the range of expanded diameters; and apply a chronic radial force to a wall that forms the portion of the lumen, wherein the radial force is less than about 0.33 N/mm; and implanting the stent assembly in the portion of the body lumen.

摘要： Apparatuses, systems, and methods for crimping prosthetic implants onto a delivery apparatus are disclosed. In some examples, a system for crimping a prosthetic valve to a delivery apparatus includes a support body having a central channel and a support surface that extends around the central channel, the support surface configured to receive the prosthetic heart valve thereon and the central channel configured for the delivery apparatus to extend therethrough. The system further includes a crimping device including a channel configured to receive the prosthetic heart valve and a first opening to the channel on a first side of the crimping device, the first opening configured to receive the support body therethrough.

摘要： A system includes a medical device for implanting in a valve of a subject, the implantable medical device having a self-expanding frame; and a holder configured to retain the frame of the implantable medical device in a constricted configuration and to control expansion of the frame. The holder has a controllably constrictable and expandable loop, wherein the loop is disposed about at least a portion of the self-expanding frame such that constriction or expansion of the first loop controls constriction or expansion of the frame.

摘要： A crimping device for a prosthetic heart valve can comprise an annular outer frame and an inner frame extending through the outer frame, the inner frame comprising first and second axial end portions and a plurality of jaw guides extending therebetween, where the inner frame defines a central opening extending therethrough. The crimping device can comprise a plurality of jaws operatively coupled to the inner and outer frames, each jaw having an inner portion positioned within the central opening of the inner frame and an engagement portion configured to slide along a respective jaw guide, each jaw guide comprising an inclined guiderail extending between the first and second axial end portions. Relative axial motion between the outer and inner frames causes radial motion of the jaws for crimping a prosthetic device positioned within the central opening.

摘要： A system for percutaneous delivery of a stented prosthetic heart valve. The system includes a delivery device with a self-expanding prosthetic heart valve attached thereto and a delivery sheath with an opening on a distal end thereof. The delivery sheath includes a funnel on a proximal end thereof. The delivery device is inserted into the funnel of the delivery sheath. As the delivery device is advanced into the funnel, the expanded heart valve is compressed by the shape of the funnel into a crimped arrangement. The delivery device further advances the heart valve distally within the delivery sheath past the delivery sheath opening. The delivery device is advanced relative to the delivery sheath in transitioning the heart valve from a crimped arrangement to the expanded and deployed arrangement.
