Blood conduit with stent
11612475 · 2023-03-28 · ·

A blood conduit with stent has a flexible conduit body and an expandable stent structure. The conduit body has a first opening end through which only an inflow of a blood enters and a second opening end through which only an outflow of the blood leaves. The stent structure includes a plurality of threads adhered to the conduit body and expands in directions intersecting an axial direction of the conduit body. A boundary of one of the threads of the stent structure closest to the second opening end is away from the second opening end with a predetermined distance, thereby preventing blood back flow into the false lumen via a new tear.

Systems and methods for heart valve therapy

Prosthetic heart valves described herein can be deployed using a transcatheter delivery system and technique to interface and anchor in cooperation with the anatomical structures of a native heart valve. Some embodiments of prosthetic valves described herein include an anchor portion that couples to the anatomy near a native valve, and a valve portion that is mateable with the anchor portion. In some such embodiments, the anchor portion and/or the deployment system includes one or more prosthetic elements that temporarily augment or replace the sealing function of the native valve leaflets.

Methods and devices for tissue grasping and assessment

Devices, systems and methods are provided for stabilizing and grasping tissues such as valve leaflets, assessing the grasp of these tissues, approximating and fixating the tissues, and assessing the fixation of the tissues to treat cardiac valve regurgitation, particularly mitral valve regurgitation.

Intravascular implants

A radially expandable, tubular stent, includes a first section having a first crush resistance force and a second section have a second crush resistance force, wherein the first crush resistance force is less than the second crush resistance force. The first section is connected to the second section to form a tube, connection of the first and second sections extending in an axial direction of the tube.

Prosthetic heart valve having leaflet inflow below frame
11484406 · 2022-11-01 · ·

Embodiments of a prosthetic heart valve are disclosed. An implantable prosthetic valve can include an annular frame having an inflow end, an outflow end and a central longitudinal axis extending from the inflow end to the outflow end. The valve can include a valvular structure including two or more leaflets, each of the two or more leaflets having a leaflet inflow edge positioned at least partially outside of the frame and a leaflet outflow edge positioned within the frame, wherein at least a portion of each of the leaflet inflow edges is unsupported by the frame.

Stent graft with pockets
11484399 · 2022-11-01 · ·

The present invention relates to a stent graft for implantation in vessels of a patient, wherein the stent graft has a hollow cylindrical main body made of a first prosthesis material, with a proximal end and a distal end, with a longitudinal axis c and a circumference u, at least one pocket element which is made of a second prosthesis material and which is mounted circumferentially on the outer face and/or inner face of the main body in order to form a circumferential closed pocket on a longitudinal portion of the main body, and at least one stent element which extends in a meandering formation around the main body and is received inside the pocket element.

MEDICAL DEVICE DELIVERY
20230029736 · 2023-02-02 ·

A stent delivery system includes a core member and an expandable member coupled to the core member distal segment. A stent extends along the core member distal segment such that an inner surface of the stent is positioned over the expandable member. The stent has a primary heat-set configuration where the stent is radially expanded, and a secondary heat-set configuration where the stent is radially compressed. The expandable member is adapted to radially expand at least a portion of the stent from a radially compressed configuration toward a radially expanded configuration.

Mitral Heart Valve Replacement

A prosthetic heart valve includes a collapsible and expandable stent extending along a longitudinal axis and having an inflow end and an outflow end, the stent including a plurality of cells annularly arranged around the stent in at least one row, the plurality of cells having a first nesting cell adjacent the outflow end of the stent, a first engaging arm disposed within the first nesting cell and being pivotally movable between a loaded condition, a partially-released condition, and a fully-released condition, the first engaging arm and the first nesting cell having a synchronous pivoting movement, and a collapsible and expandable valve assembly disposed within the stent and having a plurality of leaflets.

ADJUSTABLE FLOW GLAUCOMA SHUNTS HAVING NON-LINEARLY ARRANGED FLOW CONTROL ELEMENTS, AND ASSOCIATED SYSTEMS AND METHODS

In particular, some embodiments provide shunts having a plurality of individually actuatable flow control elements that can control the flow of fluid through associated ports and/or flow lumens. For example, each individually actuatable flow control element can be actuated to modify a flow of a corresponding port and/or flow lumen. The individually actuatable flow control elements may be actuated along a given actuation axis. A flow control assembly may include a plurality of flow control elements arranged about a collection region. Accordingly, the shunts described herein can be manipulated into a variety of configurations that provide different drainage rates based on a degree to which the ports and/or flow lumens are blocked or unblocked, therefore providing a titratable glaucoma therapy for draining aqueous from the anterior chamber of the eye.
