A stent delivery system including an elongate shaft of a medical device, a stent selectively coupled to a distal portion of the elongate shaft, and a coupling mechanism for selectively coupling the stent to the elongate shaft by inserting a tab on one of the stent or the elongate shaft into an opening in the other of the stent or the elongate shaft. The tab may be deflected from a first position to a second position to disengage the tab from the opening.

An intravascular delivery device is disclosed comprising a delivery wire having a proximal and a distal end and an interior lumen extending there between and wherein said distal end comprises a connection interface adapted to matingly interlock with a proximal end portion of a medical implantable device, wherein said delivery device comprises a locking unit arranged to secure said connection interface in a locking position in which said medical implant is pivotably locked before a controlled release.

The present embodiments provide systems and methods for improved retention of stents on a delivery system. In one embodiment, a delivery system comprises a catheter and a balloon. A proximal end of the balloon is secured to an exterior surface of the catheter at a first location, and a distal end of the balloon is secured to the exterior surface of the catheter at a second location. A plurality of bands are disposed in a circumferential space situated between the exterior surface of the catheter and an interior surface of the balloon. The plurality of bands may comprise at least four bands that are discretely spaced-apart in an axial direction from one another along a length of the catheter. At least one stent is secured to the exterior surface of the balloon in a compressed delivery state.

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.

This invention provides a stent graft transport device that can perform not only automatic rotational angle adjustment by means of self-alignment, but also smooth and easy transportation. The stent graft transport device transports a stent graft to a lesion part along a guide wire that is inserted into the inside of a blood vessel beforehand. The stent graft transport device includes a posture control member that is provided with a through bore through which the guide wire slidably passes in a curved state in one direction. The stent graft transport device is also characterized in that the posture control member is shorter than the stent graft and is mounted on a distal end part of the stent graft.

The present embodiments provide systems and methods for treating a medical condition. In one embodiment, the system comprises a stent having proximal and distal regions, and further having a delivery state and an expanded state. A therapeutic agent is disposed on a segment of the stent. The stent is disposed around an exterior surface of a core assembly in the delivery state. A coupling assembly releasably secures the proximal region of the stent to the exterior surface of the core assembly. The coupling assembly secures the stent to the core assembly for a predetermined period while the stent is in the expanded state and during release of the therapeutic agent at a target site. The coupling assembly further enables the stent to be disengaged from the core assembly and deployed in a bodily passageway.

A method for implanting a prosthesis centrally within a curved lumen includes loading a prosthesis into a delivery sheath, advancing the sheath in a patient towards the curved lumen to place at least the proximal end of the prosthesis within the curved lumen, and centering the proximal end of the prosthesis and/or the distal end of the sheath within the curved lumen. In a first advancing step, the outer catheter containing the inner sheath is advanced together towards the curved lumen to a location proximal of the curved lumen and, in a second advancing step, the inner sheath containing the prosthesis is advanced into the curved lumen to place at least the proximal end within the curved lumen while the outer catheter substantially remains at the location. After centering, the proximal end of the prosthesis is deployed centered within the curved lumen.

A heart valve delivery system may include a handle, a shaft having a proximal end fixedly connected to the handle and extending distally along an axis away from the handle to a free end, and a tube surrounding the shaft. The tube may have a proximal end connected to the handle and extend distally along the axis away from the handle to a distal end. The tube may be axially movable relative to the shaft and the handle between a fully extended position at which the tube extends distally farther than the shaft, and a fully retracted position at which the shaft extends distally farther than the tube. The system may include an inserter for guiding insertion of the tube. In addition or in alternative to the inserter, the system may include a funnel for loading the prosthetic valve into the tube.

Embodiments of an implantable frame are disclosed. The frame can have a plurality of struts interconnected to each other to form a mesh structure that is radially expandable and compressible. The frame can have a connecting post extending from an end of the frame. The connecting post can have a body portion and a head portion affixed to an end of the body portion. The head portion can have a first edge extending outwardly of the body portion. The first edge can have a substantially flat portion that is substantially perpendicular to the body portion.

A docking station for a prosthetic heart valve includes a radially expandable and collapsible frame with a first plurality of struts, an inflow end portion, an outflow end portion, and a longitudinal axis. A sealing member is disposed on the outflow end portion and configured to form a seal between the docking station and a body lumen. The docking station further includes a valve seat coupled to the frame and configured to receive an expandable prosthetic valve. The valve seat includes a second plurality of struts coupled to the frame and extending in a downstream direction and angled inwardly toward the longitudinal axis of the frame.
