The present disclosure relates to a stent delivery component, a stent delivery system and a stent system. In particular, a stent delivery component including a base and at least two clamping wings which are rotatably connected with the base, respectively, is provided. In one aspect, the stent delivery component can effectively enclose the stent to complete delivery. In another aspect, the stent delivery component is kept in line contact with an inner wall of a delivery catheter to reduce the contact area, thereby reducing the frictional resistance and being beneficial to reduce the operation difficulty and increasing the delivery efficiency.

A system for implanting a medical implant in the human or animal body, comprising: a wire-like element for connecting the system to the medical implant, a double-lumen guide tube for the wire-like element, and a handle for handling the system, wherein the medical implant is arranged at the proximal end of the guide tube and the handle is arranged at the distal end of the guide tube, and wherein the wire-like element is fixed with a first end to the handle, is guided through a first lumen of the double-lumen guide tube to the medical implant, engages with a connecting device of the medical implant and is guided through a second lumen of the double-lumen guide tube to the handle and is detachably fixed to the handle with a second end.

Various examples address support structures (e.g., prosthetic valve support structures or frames) that incorporate a frame that, upon transitioning to a deployed configuration, include a proximal section has increased stiffness, or resistance to deformation in a transverse plane to a longitudinal axis of a device, including resistance to a change in shape, size, or both. Such an increase in transverse deformation resistance may be measured as an increase in radial compressive resistance or an increase in flat plate stiffness, for example, or both. Such increases in transverse deformation resistance may be realized through a reduction in length of the increased stiffness region of the support structure, such as through longitudinal compression of the region following an initial radial expansion of the region.

A stent configured to change in length while maintaining a constant inner diameter is disclosed. The stent includes an elongated tubular member comprising at least one knitted filament forming a plurality of twisted knit stitches with rungs extending circumferentially between adjacent twisted knit stitches, wherein each twisted knit stitch is interconnected with a longitudinally adjacent twisted knit stitch forming a series of linked stitches. The tubular member is configured to be stretched from a first length to a second length while in a radially expanded configuration without substantially changing the inner and/or outer diameter of the tubular member.

A medical device system may include an elongate shaft having a lumen extending from a proximal end to a distal end, a proximal release wire, and a distal release wire. The proximal release wire may extend distally from a proximal end configured to remain outside the body to a distal end and may be slidably disposed within the lumen of the elongate shaft. The distal release wire may extend distally from a proximal end to a distal end and may be slidably disposed within the lumen of the elongate shaft. The proximal end of the distal release wire may be slidably coupled to the distal end of the proximal release wire. The distal release wire may be configured to releasably attach a medical device to the distal end of the elongate shaft.

The invention relates to an endoprosthesis (60), in particular a vascular stent or a heart stent. The endoprosthesis comprises a stent structure (2) with a stent surface (3) and has at least one fiber (1) arranged on the stent surface (3). The stent structure (2), preferably the stent surface (3), comprises an attachment mechanism (4,5,6,7) to directly attach a fiber (1) on the stent.

The present disclosure relates to numerous delivery devices and methods for transcatheter prosthetic heart valve loading, deployment and delivery utilizing at least one suture. Disclosed delivery devices utilize improved suture routing methods and configurations that reduce suture tangling and also provide the ability to adjust the prosthetic heart valve expansion and contraction prior to the final release of the prosthetic heart valve from the delivery device.

A prosthetic valve delivery apparatus can comprise a handle, a gearbox, an input torque shaft and a plurality of output torque shafts. The input torque shaft can extend distally from the handle and can have a distal end portion operatively connected to the gearbox. The output torque shafts can be operatively connected to and extend distally from the gearbox. Rotation of the input torque shaft can cause rotation of the output torque shafts via the gear box.

A stent delivery system includes a core member and a coupling assembly rotatably coupled to the core member distal segment. The coupling assembly includes first and second plates and first and second spacers. The first plate is rotatably coupled to the core member and includes an outer surface having three or more projections separated by recesses. The first spacer is coupled to the core member and disposed between the first plate and a proximal restraint. The second plate is rotatably coupled to the core member and includes an outer surface having three or more projections separated by recesses. The second spacer is coupled to the core member and disposed between the first plate and the second plate. A stent extends along the core member distal segment such that an inner surface of the stent is engaged by one or more projections of the first plate or the second plate.

Delivery systems for expandable elements, such as stents or scaffolds having spikes, flails, or other protruding features for penetrating target tissue and/or delivering drugs within a human patient are described along with associated methods for using such systems. The delivery systems can be provided with a stent that is positioned over an inflatable balloon for expansion and delivery of the stent to a target delivery location. By positioning the stent over and about the inflatable balloon, the stent is ready to be expanded by the balloon immediately upon unsheathing with respect to the outer shaft. Additionally or alternatively, a stent can be positioned in an axially offset arrangement with respect to a balloon to reduce the need for space required by overlapping components.
