A method of treating mitral valve stenosis in a human heart includes advancing a delivery apparatus through a right femoral vein, across a septal wall, and through a calcified mitral valve. A prosthetic heart valve is provided along a distal end portion of the delivery apparatus, wherein the prosthetic heart valve includes a metallic frame having a plurality of tissue-engaging elements positioned along an exterior surface and a leaflet structure for replacing the function of the calcified mitral valve. The prosthetic heart valve is radially expanded within an annulus of the calcified mitral valve such that at least some of the tissue-engaging elements of the prosthetic heart valve embed into the annulus. After radial expansion, the prosthetic heart valve is retained in position within the annulus via the tissue-engaging element and the leaflet structure replaces the function of the native mitral valve.

Method of treating mitral valve stenosis

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

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

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.

A prosthetic heart valve is radially collapsible to a collapsed configuration and radially expandable to an expanded configuration. The heart valve includes an annular inner frame formed with a plurality of angled first strut members, the inner frame being configured to foreshorten from a first length corresponding to the collapsed configuration to a second length corresponding to the expanded configuration. A leaflet structure is situated at least partially within the inner frame. An outer frame is disposed radially outward of the inner frame and coupled to the inner frame. The outer frame is configured to collapse with the inner frame and radially expand with the inner frame, and includes a plurality of second strut members. Portions of the second strut members are configured to bend radially outwardly into a curved shape as the inner frame and the outer frame move from the collapsed configuration to the expanded configuration.
