A venous valve prosthesis includes a frame and a prosthetic valve coupled to the frame. With the venous valve prosthesis implanted in a vein, the prosthetic valve includes a closed configuration wherein an outer surface of the prosthetic valve is in contact with a wall of the vein around a circumference of the prosthetic valve to prevent blood from flowing past the prosthetic valve between the wall of the vein and the outer surface of the prosthetic valve. The prosthetic valve is configured to move to an open configuration such that at least a portion of an outer wall of the prosthetic valve partially collapses away from the wall of the vein in response to antegrade blood flow through the vein to enable blood flow between the outer surface of the prosthetic valve and the wall of the vein.

A prosthetic valve including a wire frame having a generally tubular body portion, an interior area, a longitudinal axis, a first end comprising a plurality of crowns, and a second end comprising a greater number of crowns than the first end. The wire frame includes a plurality of adjacent rows of modified diamond-shaped structures extending between the first and second ends. The prosthetic valve further includes a valve structure that includes a plurality of leaflets and that is attached within the interior area of the wire frame.


Patent
Medtronic Inc. | Date: 2017-06-28

A delivery device (72) for implanting a prosthetic heart valve. The device includes an inner shaft assembly (82), an outer sheath (80) and a connector assembly (86). The inner shaft assembly defines a guide wire (74) lumen. The outer sheath is slidably received over the inner shaft assembly, and forms an exit port (92) proximate a distal end thereof. The connector assembly establishes a guide wire passageway between the guide wire lumen and the exit port. The connector assembly is configured to permit sliding movement of the outer sheath relative to the inner shaft assembly when deploying the prosthetic heart valve. The connector assembly can include first and second tubes that are slidable relative to one another in facilitating movement of the outer sheath relative to the inner shaft assembly.

Medtronic Inc. | Date: 2017-03-01

A paravalvular leak resistant prosthetic heart valve system (20) including a stent frame (22), a valve structure (24) and a sealing mechanism (30). The stent frame has a surface. The valve structure is associated with the stent frame. The sealing mechanism at least partially extends over the surface of the stent frame. The sealing mechanism includes at least one semi-permeable membrane and an osmotic gradient driving material.

A delivery system (100) for delivering a prosthesis includes a sheath (106), a slide shaft (128) having a threaded outer surface (130), and a handle (110). The handle includes an internal spring assembly (116) for selectively engaging and disengaging the handle with the threaded outer surface of the slide shaft. The internal spring assembly includes at least one spring arm (120), a head (122) coupled to the spring arm and having a circumferentially rounded threaded inner surface (124), and a ring (118) slidably disposed over the spring arm. When the ring is in a first longitudinal position, the threaded inner surface of the head is spaced apart from the threaded outer surface of the slide shaft. When the ring is in a second longitudinal position, the threaded inner surface of the head is threadedly engaged with the threaded outer surface of the slide shaft. The handle may include a resilient cover (1312) to provide the internal spring assembly with a biased or nominal operational position.

A bioerodible stent includes an inner member of a first biocompatible metal, an intermediate member of a second biocompatible metal, and an outer member of a third biocompatible metal. The first biocompatible metal, second biocompatible metal, and third biocompatible member are selected such that galvanic corrosion occurs between the members. A biodegradable polymer coating may surround the members.


Patent
Medtronic Inc. | Date: 2017-08-02

A method for forming a stent with hollow struts is disclosed, comprising the steps of: providing a first tube made from a first material; placing a second tube made from a second material over the first; after a removing step of removing portions of the wall of the first tube, placing a third tube made from the second material inside the first tube; pressing the first, second, and third tubes together; removing portions of the walls of the second tube and the third tube; and processing the remaining material such that material of the first tube is removed without damaging remaining material of the second and third tubes.


Patent
Medtronic Inc. | Date: 2017-07-26

A package (30) for a medical device having an elongated shaft and a proximal luer fitting, the package includes a one-piece body (32) formed as a single structure. The one-piece body includes at least a spiral casing formed therein, the spiral casing defining a spiral lumen (34) configured to receive the elongated shaft of the medical device. The package includes a luer retaining portion (36) at one end of the spiral casing with barrier film (60) sealed to the luer retaining portion to maintain the sterility of the medical device. The package further including a cap (100) placed over the luer retaining portion and barrier film to protect the integrity of the barrier film and prevent perforation of the barrier film which would compromise the sterility of the medical device.


Patent
