A medical assembly can include a radially expandable prosthetic heart valve and a delivery apparatus. The delivery apparatus can include a handle, an actuation member, and a force limiting mechanism within the handle including a pivot arm coupled to a base portion. The actuation member can apply a proximally directed force to the prosthetic valve to cause the valve to expand. The actuation member can be coupled to the pivot arm such that a force applied to the actuation member causes the pivot arm to pivot. The force limiting mechanism can pinch the actuation member between the pivot arm and the base portion when the force applied to the actuation member exceeds a predetermined force to prevent proximal movement of the actuation member and can allow proximal movement of the actuation member to produce radial expansion of the prosthetic valve when the force applied is less than the predetermined force.

Force limiting mechanism for prosthetic heart valve delivery apparatus

An implantable prosthetic device can include a frame that is radially expandable and compressible between a radially compressed configuration and a radially expanded configuration. The frame can have a first set of a plurality of struts extending in a first direction, and a second set of a plurality of struts extending in a second direction, and each strut of the first set of struts can be pivotably connected to at least one strut of the second set of struts. Each strut can be curved helically with respect to a first, longitudinal axis of the frame, and each strut can be curved with respect to a second axis that is perpendicular to the first, longitudinal axis of the frame.

Prosthetic heart valve having non-cylindrical frame

A system includes a lock and release connector, an implantable medical device, and an outer tube. The lock and release connector includes a connector body defining a recess having planar lateral head portions extending to and intersecting with a cylindrical surface of the connector body, and a longitudinal neck portion extending from the head portion. The implantable medical device has an extension including a neck portion receivable in the longitudinal neck portion of the recess and a head portion receivable in the lateral head portions of the recess. The outer tube extends over the recess to retain the extension in the recess.

Lock and release mechanisms for trans-catheter implantable devices

Valvular implants and blood vessel closure devices herein are configured to be positioned in the heart and to block regurgitant blood flow from the heart into blood vessels supplying blood to the heart. The valvular implants can have a cover, a membrane, a valve, a resilient frame, and/or other features. Some valvular implants can have anchors to be positioned in the blood vessels, such as in pulmonary veins, and can anchor the implant to the heart wall. Various embodiments of covers and/or membranes act as valves contracting and expanding, to alternately permit and block blood flow. The valvular implants can cover one or more blood vessels, such as one, two, three, or four pulmonary veins, and can also be configured and implanted to block an appendage to the heart, such as the left atrial appendage.

Unidirectional valvular implant

An expandable docking station includes an annular valve seat having an end, an annular outer wall comprising struts disposed around the valve seat, and links that connect the end of the annular valve seat to the annular outer wall. Each of the links extends from the struts of the annular outer wall directly toward a longitudinal axis that runs longitudinally through a center of the docking station, and to a corresponding one of a plurality of circumferentially spaced axially extending legs at least partially defining the annular valve seat. The outer wall is configured to conform to an interior shape of a blood vessel, when expanded inside the blood vessel, such that the outer wall can expand in multiple locations to conform to multiple bulges of the blood vessel and can contract in multiple locations to conform to multiple narrowed regions of the blood vessel.

Docking stations for transcatheter valves

Devices, systems and methods are described herein to provide improved steerability for delivering a prosthesis to a body location, for example, for delivering a replacement mitral valve to a native mitral valve location. The delivery system can include a number of advantageous steering and delivery features, in particular for the transseptal delivery approach.

Steerable delivery system for replacement mitral valve and methods of use

Systems and methods usable in delivering a docking device to a native valve of a patient's heart. A distal region of a delivery catheter can be positioned in an atrium of the heart and a distal tip can be positioned at or near a commissure of the native valve. The docking device can be located within the delivery catheter. A pusher, such as a pusher wire or tube, of a pusher tool can be advanced distally through the delivery catheter, wherein the pusher can push the docking device along within the delivery catheter. The docking device can be connected to the pusher tool by a line, such as a suture. A member of the pusher tool can be rotatable to change the amount of the suture extending from the pusher tool.

Systems and mechanisms for deploying a docking device for a replacement heart valve

Delivery systems and catheters including lock and release connectors for implantable devices and methods for retaining, positioning, and deploying a medical device are disclosed. The lock and release connectors can include a body and at least one door engaged with the body, wherein the door is moveable from a first position to a second position. The lock and release connectors can further include at least one fastener connecting at least one end of the door to the body. The door can be integral with the body or connected and can comprise a shape memory material and/or other materials.

Docking stations for transcatheter valves are described. The docking stations can include an expandable frame, at least one sealing portion, and a valve seat. The expandable frame can be configured to conform to an interior shape of a portion of the circulatory system when expanded inside the circulatory system. The sealing portion can be configured to contact an interior surface of the circulatory system to create a seal. The valve seat can be connected to the expandable frame and can be configured to support an expandable transcatheter valve. The docking stations are adaptable to different anatomies/locations to allow implantation of a transcatheter valve in a variety of anatomies/locations.
