A prosthetic implant transfer device is provided that may be used to insert a prosthetic implant through a surgical opening. In some embodiments, the device may comprise a flexible sheet of material that may be formed into an elongated hollow structure. The flexible sheet of material includes a plurality of fasteners that may be selected and engaged to define a desired size distal opening.

Apparatus, systems, and methods for inserting prosthesis implants into surgically-created implant pockets in a subject and for preventing capsular contracture resulting from surgical insertion of prosthesis implants. The apparatus includes a base having an upper surface and a lower surface and having an aperture formed therein which extends through the upper surface and the lower surface of the base. The apparatus also includes a tubular member that is coupled to the base. The inner bore of the tubular member is operable to receive the implant and has a substantially uniform cross-sectional width over the predetermined length. The apparatus is capable of shielding the implant from microbial contamination, including contamination by the endogenous flora of the subject, during insertion of the implant into the surgically-created implant pocket.

Provided is an embolic protection device with dual-layer filter meshes, including an elastic base frame, a first filter mesh and a second filter mesh. The two ends of the first filter mesh are the first open end and the first closed end respectively. The distance between the first closed end and the elastic base frame is greater than the distance between the first open end and the elastic base frame. The first open end is connected with the elastic base frame, and the first filter mesh is provided with a plurality of first filtering holes. The second filter mesh is provided with a plurality of second filtering holes.

The present invention relates to an anti-reflux valve for preventing gastro-esophageal reflux disease and includes a body formed in a ring shape and fixed to an upper end of a gastro-esophagus; a reflux blocking plate coupled to an inner circumferential surface of the body to be rotatable in one direction; and a fixing clip coupled to an outer circumferential surface of the body to fix the body to the upper end of the gastro-esophagus.

An embolic protection system may include a delivery catheter, a core wire slidably disposed within a lumen of the delivery catheter, an expandable support frame, and a filter element coupled to the expandable support frame. The filter element is a material configured to allow blood flow therethrough while blocking a passage of embolic debris. The embolic protection device may be positioned within the ascending aorta with a distal end located between the aortic valve and the coronary arteries.

A method for treating a native valve of a human heart having a native annulus and native leaflets includes positioning a capsule of a delivery device proximate a native heart valve. The method further includes partially deploying a prosthetic heart valve device from the capsule such that an inflow region of a valve support and an inflow region of a fixation structure are radially expanded. A portion of the prosthetic heart valve device remains coupled to the delivery device while a gap exists between a downstream end of a prosthetic valve disposed within the valve support and a distal terminus of the capsule such that fluid can flow through the prosthetic valve with the prosthetic heart valve device partially deployed. The method may further include recapturing the prosthetic heart valve device within the capsule.

Devices, systems, and methods for treating a blood flow passage are disclosed herein. For example, expandable devices of the present technology may comprise a stent having a collapsed configuration for delivery through a delivery device to a treatment site in a body conduit and an expanded configuration. The stent may comprise a plurality of struts and longitudinally extending first and second spines configured to move in opposing axial directions as the stent expands. Each of the struts may extend between and connect one of the first spines and one of the second spines. Moving the first spines axially relative to the second spines may cause the struts to push circumferentially adjacent spines to move away from one another, thereby increasing a diameter of the stent.

The present invention relates to an anchoring system for attaching a prosthesis to a human body, comprising: an anchoring element, an abutment, an abutment screw for attaching the abutment to the anchoring element, the anchoring element comprises a connection area for the abutment, the connection area comprising a press-fit portion such that the abutment is attached to the anchoring element in the connection area by a press-fit connection, wherein the connection area comprises an anti-rotation geometry and the abutment comprising a corresponding mating anti-rotation geometry proximal to the press-fit portion, and where in the connection area comprises a conical portion proximal to the anti-rotational geometry forming a mating geometry for a corresponding conical portion in the through-hole of the abutment.

A percutaneous heart valve prosthesis including a collapsible valve body frame has a first end and a second end. The valve body frame is formed by a plurality of sub-frame members, each sub-frame member having a general form of a diamond with acute-angled vertices and oblique-angled vertices, wherein adjacent sub-frame members are joined at the oblique-angled vertices. A flexible skirt made from pericardial material extends around a periphery of the valve body frame. A one-way valve including a plurality of flexible valve leaflets is positioned within the valve body frame. The first end of the valve body frame is sized to pass through a valve orifice associated with a heart valve to be replaced and the second end of the valve body frame is sized so as not to pass through a valve orifice.

A luminal endoprosthesis assembly (1) at least partially delimits a prosthesis lumen (2), for implantation in an anatomical structure (3) that at least partially defines at least one cavity (4) and includes at least one pathological portion (13). The luminal endoprosthesis (1) has two or more layers (5, 6, 7). At least one layer (5, 6, 7) includes a threadlike element (8) forming an armor (9). The luminal endoprosthesis (1) includes an anchoring portion (10) for anchoring to an anatomical portion (11) of the walls of the cavity (4) of the anatomical structure (3), and a working portion (12) for facing the pathological portion (13) of the anatomical structure (3). The two or more layers (5, 6, 7) are separated from each other in the working portion (12) of the luminal endoprosthesis (1), avoiding connecting elements between one layer (5, 6, 7) and at least one adjacent layer.
