  • Patent number: 11185407
    Abstract: The invention describes a stent of the aortic valve which is self-expandable and also repositionable and preferably made from nitinol. It consists of two parts: the upper part and the lower part. The lower part is a mesh (1) laid out so that it creates a kind of cylinder wall on the entire height of the element. Also other shape of the mesh is acceptable, for example partially conical, or partially resembling flattened side wall of the cylinder. However, the upper part of the stent consists of derived from the mesh (1) upwards and arranged at equal intervals three arms (2) the height of which is slightly larger than the height of the mesh (1), a bit less than the height of the mesh (1) or equal to its height. The stent arms (2) are shaped in such a way that they form together a kind of an oval chalice bowl, and their end, peripheral part is preferably straight and also inclined to the middle. Space between the arms (2) always ensures free access to patient's coronary arteries.

  • Patent number: 11179238
    Abstract: A valved conduit including a bioprosthetic valve, such as a heart valve, and a tubular conduit sealed with a bioresorbable material. The bioprosthetic heart valve includes prosthetic tissue that has been treated such that the tissue may be stored dry for extended periods without degradation of functionality of the valve. The bioprosthetic heart valve may have separate bovine pericardial leaflets or a whole porcine valve. The sealed conduit includes a tubular matrix impregnated with a bioresorbable medium such as gelatin or collagen. The valved conduit is stored dry in packaging in which a desiccant pouch is supplied having a capacity for absorbing moisture within the packaging limited to avoid drying the bioprosthetic tissue out beyond a point where its ability to function in the bioprosthetic heart valve is compromised. The heart valve may be sewn within the sealed conduit or coupled thereto with a snap-fit connection.

  • Patent number: 11173027
    Abstract: A side-deliverable prosthetic valve includes an outer frame, a flow control component mounted within the outer frame, and an anchoring element coupled to a distal side of the outer frame. The prosthetic valve is foldable along a longitudinal axis and compressible along a central axis to a compressed configuration for side delivery via a delivery catheter and is expandable to an expanded configuration when released from the delivery catheter. An end portion of the anchoring element is configured to engage a guide wire. The anchoring element is extended during deployment to allow the anchoring element to capture at least one of native leaflet or chordae and, in response to the guide wire being disengaged from the end portion, transitions to a folded configuration to secure at least one of the native leaflet or the chordae between the anchoring element and the distal side of the outer frame.

  • Patent number: 11141270
    Abstract: A prosthetic heart valve for replacing a defective aortic valve includes a self-expandable annular frame made of shape-memory material. A one-way valve structure is disposed within an interior of the frame. The frame includes a plurality of posts projecting axially from an outflow end portion of the frame, wherein each of the posts includes an axial post portion and a terminal post portion. The terminal post portions have greater circumferential dimensions than the axial post portions. The terminal post portions are preferably formed with concave inner surfaces and convex outer surfaces for conforming to the shape of a delivery catheter. Each of the posts is shaped for placement within a corresponding recess along a distal end portion of the delivery catheter for ensuring that the prosthetic heart valve remains coupled to the delivery catheter while the prosthetic heart valve is expanded within the defective aortic valve.

  • Patent number: 11135051
    Abstract: A device for inserting a pre-filled or silicone prosthesis into a surgical pocket is formed from a sleeve formed of a bottom layer and a top layer attached to the bottom layer along longitudinal edges of the bottom layer and top layer. The top layer has a greater width than the bottom layer so as to form a half-cylinder shape when the sleeve is filled. The sleeve has a constant cross-sectional area along a length of the sleeve. This device reduces the chances for the implant to rotate in an unintended manner due to the non-circular cross-section of the sleeve.

  • Patent number: 11135055
    Abstract: This invention relates to the design and function of a compressible valve replacement prosthesis, collared or uncollared, which can be deployed into a beating heart without extracorporeal circulation using a transcatheter delivery system. The design as discussed focuses on the deployment of a device via a minimally invasive fashion and by way of example considers a minimally invasive surgical procedure preferably utilizing the intercostal or subxyphoid space for valve introduction. In order to accomplish this, the valve is formed in such a manner that it can be compressed to fit within a delivery system and secondarily ejected from the delivery system into the annulus of a target valve such as a mitral valve or tricuspid valve.

  • Patent number: 11129710
    Abstract: A method of implanting a prosthetic heart valve within a patient can comprise inserting a distal end portion of a delivery apparatus and a prosthetic heart valve into the patient and advancing the prosthetic heart valve to a deployment location within the heart of the patient and inflating one or more of a plurality of differently-sized balloons in a balloon-assembly on the distal end portion of the delivery apparatus. The prosthetic heart valve can be mounted on the balloon assembly in a crimped state and the inflating of the one or more of the plurality of differently-sized balloons can expand the prosthetic heart valve from the crimped state to a radially expanded state having a non-cylindrical shape.

  • Patent number: 11129701
    Abstract: The embodied invention is a lip implant that includes small eyelets on either end of a small diameter rod located inside, and extends beyond, the cosmetic volume of the implant. Sutures connected to eyelets on the rod ends, allow the implant to be pulled into a minimal lip cavity that is created for the implant. The implant is readily positioned by using the sutures. Only two small incisions are needed as well as the creation of a small cavity needed for the implant. The use of the embodied invention is also extended to vein implants to enhance the appearance of veins on arms, legs, or to other surfaces.
