摘要： Devices and methods for reinforcing a regenerative heart valve are provided. A reinforcing element can provide structure and rigidity to withstand stresses that occur within the aortic root. In some instances, a support ring is attached to a regenerative heart valve. In some instances, a tubular wall is provided surrounding a regenerative heart valve.

摘要： A method of shunting blood involves accessing a left atrium of a heart with a surgical instrument, advancing the surgical instrument into a pulmonary vein fluidly coupled to the left atrium, forming an opening in a wall portion of the pulmonary vein, and shunting blood from the pulmonary vein into a right-side structure of the heart through the opening in the wall portion of the pulmonary vein.

摘要： An annuloplasty ring prosthesis comprising a frame having an outer surface; and a cover surrounding the frame. The cover comprises a bioprosthetic tissue that can be regenerative or fixed and non-regenerative. The frame can be bioabsorbable or non-degradable. A ring prosthesis and a method of manufacturing a ring prosthesis is also provided. The ring prosthesis comprising an elongated rod member formed into a substantially ring shape, the elongated rod member being formed substantially from a flat bioprosthetic tissue.

摘要： The present disclosure is directed to embodiments of automated crimping systems, methods of crimping prosthetic valves, and methods of using automated crimping systems to crimp prosthetic valves. In some embodiments, an automated crimping system includes a crimper controller, a rotary actuator, an outer crimper housing, and a crimper mechanism mounted within the outer crimper housing. In some embodiments, an automated method of crimping a prosthetic valve includes inserting a prosthetic valve into an automated crimping system, activating the automated crimping system, and removing the crimped prosthetic valve from the automated crimping system. In some embodiments, a method of crimping a prosthetic valve comprises partially crimping the prosthetic valve at a first speed to a partially crimped configuration and further crimping the prosthetic valve at a second speed.

摘要： Artificial heart valves, their manufacture, and methods of use are described. Generally, artificial heart valves can be deployed to replace or supplement defective heart valves in a patient. These artificial heart valves can comprise a frame with an inner skirt and leaflets. These inner skirt and leaflets can be generated from regenerative tissue to allow integration of the tissue with the body of a patient, while the frame can be generated from bioabsorbable material to allow dissolution of the frame over time. This combination of materials may allow for the artificial valve to grow with a patient and avoid costly and potentially dangerous replacement for patients receiving artificial valves.

摘要： A method of applying fibrous material to a medical device component involves coupling a medical device component a holder device, rotating a reservoir device containing a liquid polymeric solution to expel at least a portion of the liquid polymeric solution from an orifice of the reservoir device, the expelled at least a portion of the liquid polymeric solution forming one or more strands of fibrous material in a deposition plane, and rotating the holder device at least partially within the deposition plane to apply at least a first portion of the one or more strands of fibrous material to one or more surfaces of the medical device component, thereby forming a fibrous covering on the one or more surfaces of the medical device component.
