A valve implant includes an occlusive assembly and a frame coupled to the occlusive assembly. The frame transitions from a collapsed state to an expanded state about a central longitudinal axis and transitioning from the collapsed state to the expanded state causes a proximal end of the frame to expand radially outward from the central longitudinal axis. The valve implant further includes an outer sheet supported on a proximal portion of the frame. The occlusive assembly is supported on a distal portion of the frame such that the inner sheet extends about the central longitudinal axis and an annular opening is defined between the outer sheet and the inner sheet when the frame is in the expanded state.

System and method for cardiac valve repair

An intravascular device delivery system has an elongated member, a guidewire receiving member, and a distal cap longitudinally fixed to a guidewire receiving member. The distal cap includes an insert having an elongate member, a rim member radially separated from the elongate member, and a wall member supporting the rim member, the wall member being disposed between the rim member and the elongate member.

Insert for distal end cap

A system for delivery of cardiac implants includes a catheter having a handle assembly including a cable control assembly. The handle assembly further includes a tubular body assembly extending distally from the handle assembly and deflectable by operation of the cable control assembly. The system also includes a robot having a linear displacement platform and a carriage coupled to the linear displacement platform. The carriage includes a drive motor assembly and is at least one of linearly displaceable along the linear displacement platform and rotatable relative to the linear displacement platform. The handle assembly is coupled to the carriage such that the cable control assembly interfaces with the drive motor assembly of the carriage to facilitate operation of the cable control assembly by the robot.

Robotic delivery system for cardiac implants

A replacement heart valve comprises a unibody, folded, double-wall stent, with a stent cover and a leaflet valve attached to the inner lumen of the stent. The heart valve is delivered using a multi-pulley, suture-based stent restraint assembly provided by fixed guide openings or structures along the distal end of the delivery system that independently permits expansion of the distal and proximal ends of the outer wall of the stent, and control of the inner wall expansion simultaneously with or separately from the expansion of the outer wall.

Systems, devices and methods for folded unibody heart valve stents

A delivery device includes a handle, a central elongate member extending from the handle, a sheath configured to slide over and relative to the central elongate member, a distal tether retainer at a distal end of the central elongate member, a proximal tether restraining mechanism positioned along the central elongate member distal of the handle and proximal of the distal tether retainer, and a plurality of tethers. The tethers are configured to extend from the proximal tether restraining mechanism to the distal tether retainer.

Cardiac valve delivery devices and systems

Delivery systems for expandable and stented implants include adjustable tensioning members that control the expansion of the implant along the length of the implant. The tensioning members are wound onto one or more rotors located on the distal segment of the delivery system, which are rotated to unwind the tensioning members and incrementally expand the implant. Positioning mechanisms are also provided to adjust the position and orientation of the implant during delivery.

Systems, devices and methods for delivery systems

A delivery device for cardiac valve repair implants includes a delivery catheter and an extension member protruding from a distal end of the delivery catheter. The delivery device further includes a control arm assembly having pairs of control arms. Each pair includes a proximal control arm drivable from a handle assembly of the delivery device and a distal arm coupled to a distal end of the proximal control arm and a distal end of the extension member. Proximally driving each of the proximal control arms of the control arm assembly results in expansion of the control arm assembly and corresponding expansion of a cardiac valve repair implant coupled to the control arm assembly.

A prosthetic valve delivery device includes a handle and a delivery catheter. The delivery catheter includes a central elongate member extending from the handle and a proximal sheath configured to slide over and relative to the central elongate member. The proximal sheath is connected to a hollow helical strand, and the hollow helical strand is configured to rotate to retract the proximal sheath and expose at least a portion of the prosthetic valve.

A delivery device includes a central elongate structure including an annular member at the distal end, a sheath, a plurality of tethers extending through the central elongate structure, a handle, and a control on the handle. The handle is connected to the elongate structure, the sheath, and the plurality of tethers. The control is configured to move the sheath proximally and distally over the central elongate structure. The annular member includes a plurality of pockets extending radially therearound. Each tether includes a feature on a distal end thereof configured to fit within a pocket of the plurality of pockets to hold the tethers in place.

A prosthetic mitral valve includes an anchor assembly, an annular strut frame, and a plurality of replacement leaflets secured to the annular strut frame. The anchor assembly includes a ventricular anchor, an atrial anchor, and a central portion therebetween. The annular strut frame is disposed radially within the anchor assembly. An atrial end of the annular strut frame is attached to the anchor assembly such that a ventricular end of the annular strut frame is spaced away from the anchor assembly.

Replacement mitral valves

A delivery device includes a central elongate structure, a sheath, a plurality of tethers extending through the central elongate structure configured to hold a cardiac valve, a cutting mechanism, a handle, and a control. The sheath is configured to slide over the central elongate structure. The cutting mechanism is configured to cut the tethers upon activation to release the cardiac valve. The handle is connected to the central elongate structure. The control on the handle is configured to activate the cutting mechanism.

A cardiac valve repair implant, wherein the implant includes a central occluder, and frame and a thin sheet. The central occluder includes a central longitudinal axis. The frame extends proximally from the central occluder and is centered about and forms a circumference around the central longitudinal axis of the central occluder. The frame self-biases from a collapsed state to an expanded state. A proximal end of the frame projects proximally when the frame is in the collapsed state. The proximal end of the frame projects radially outward away from the central longitudinal axis of the central occluder when the frame is in the expanded state. The thin sheet is supported on a proximal portion of the frame. When the frame is in the expanded state, the thin sheet forms an annular surface defining an inner circular opening centered about the central longitudinal axis of the central occluder.
