  • Publication number: 20200054452
    Abstract: A delivery system for percutaneously deploying a prosthetic heart valve. The system includes an inner shaft assembly, a delivery sheath capsule and a handle maintaining a first actuator and a second actuator. The capsule is configured to compressively retain the prosthetic heart valve over the inner shaft assembly. The first actuator is operated to proximally retract the delivery sheath capsule and expose the prosthetic heart valve relative to the capsule. The second actuator is operated to proximally retract the prosthetic heart valve by transmitting forces to the inner shaft assembly.

  • Publication number: 20190321160
    Abstract: A stent-graft prosthesis for implantation within a body vessel includes a graft material, a frame, and a channel. The graft material includes a proximal end, a distal end, and a graft lumen extending between the proximal and distal ends. The frame is coupled to the graft material. The channel is configured to relieve pressure associated with pulsatile blood flow during implantation of the stent-graft prosthesis within a body vessel. The channel permits blood to flow from an upstream side of the stent-graft prosthesis to a downstream side of the stent-graft prosthesis when the stent-graft prosthesis is in a partially expanded configuration in the body vessel. The channel may be a plurality of channels.

  • Publication number: 20170312484
    Abstract: A medical device includes an inflatable balloon defining an interior surface and an exterior surface, and a coating including a therapeutic agent disposed on the exterior surface of the inflatable balloon. The coating has a release transition temperature within a range from about 25° C. to about 50° C. When the temperature of the coating is below the release transition temperature, the coating retains at least a portion of the therapeutic agent on the exterior of the inflatable balloon. When the temperature of the coating is above the release transition temperature, the coating releases at least a portion of the therapeutic agent from the exterior of the inflatable balloon.

  • Publication number: 20160338862
    Abstract: Distal tips for use with delivery catheters are disclosed that are configured to maintain complete engagement between the distal tip and a distal opening of a sheath component of the delivery catheter so as to prevent separation therebetween and/or to prevent fish-mouthing of a distal leading edge of the sheath component during in vivo use. Distal tips so configured realize one or more of the objectives of safer tracking of the delivery catheter through the vasculature, safe crossing of the delivery catheter through structural components of the vasculature and heart, such as through native valves, and safe removal of the delivery catheter post deployment.

  • Patent number: 9456897
    Abstract: A method of preventing paravalvular leakage includes concurrent delivery of a heart valve prosthesis and an annular sealing component. During delivery, the sealing component is moved from a first position to a second position of the heart valve prosthesis which is longitudinally spaced apart from the first position of the heart valve prosthesis. The sealing component is secured around the heart valve prosthesis at the second position by a contoured outer surface of the heart valve prosthesis. The sealing component may be a flexible ring or may be a cylindrical flexible sleeve having a plurality of ribs longitudinally extending over the cylindrical sleeve. The ribs operate to deploy the sealing component such that at least a portion of the cylindrical sleeve buckles outwardly away from the outer surface of the heart valve prosthesis.

  • Patent number: 9173738
    Abstract: A delivery system for use with a prosthetic heart valve having a stent frame to which a valve structure is attached includes a shaft assembly including a distal end, an intermediate portion, and a first coupling structure disposed near the distal end and configured to be coupled to a distal end of the prosthetic heart valve via a first tether. A sheath assembly defines a lumen sized to slidably receive the shaft assembly. The delivery system is configured to transition from a loaded state in which the sheath assembly encompasses the prosthetic heart valve to a deployed state in which the sheath assembly is withdrawn from the prosthetic heart valve. The first coupling structure is configured to be manipulated in a first direction to provide a controlled expansion or contraction of the distal end of the prosthetic heart valve.

  • Patent number: 9132008
    Abstract: A delivery device for percutaneously deploying a prosthetic valve includes a sheath, an inner shaft, and a release assembly. The release assembly is disposed between the sheath and the inner shaft, and includes a retraction member, a release member, and a retention member. The retraction member can self-retract in length from an extended condition to a retracted condition. The release member can self-expand from a compressed condition to an expanded condition. The retention member is distal the release member. In a delivery state, the sheath end is distal the retention member, the release member is in the compressed condition and the retraction member in the extended condition to retain the prosthesis. In a deployment state, the sheath end is positioned to permit the release member to self-transition to the expanded condition, allowing the retraction member to self-transition to the retracted condition and release the prosthesis.

  • Publication number: 20150148898
    Abstract: A transcatheter valve prosthesis includes an expandable tubular stent, a prosthetic valve within the stent, and an anti-paravalvular leakage component coupled to and encircling the stent which includes a plurality of self-expanding struts and an annular sealing membrane. Each strut has a first end coupled to a distal end of the stent and a second end not coupled to the stent. Each anti-paravalvular leakage component is moveable between a compressed configuration and a deployed configuration. In the compressed configuration, each strut extends distally away from the distal end of the stent. In the deployed configuration, each strut extends proximally away from the distal end of the stent. In an embodiment hereof, the deployed strut has a C-shape and is twisted such that the C-shape lies in a plane substantially along or tangential with the outer surface of the stent. In another embodiment hereof, the deployed strut is rolled-up and extends radially away from the outer surface of the stent.

  • Patent number: 8974524
    Abstract: A percutaneous stented valve delivery device including an inner shaft, a sheath, and a delivery capsule. The sheath slidably receives the inner shaft. A capsule proximal zone is attached to the sheath. A capsule distal zone is configured to transition between normal and flared states. A diameter of the distal zone is greater in the flared state, and the capsule includes a shape memory component that naturally assumes the normal state. The device is operable to perform a reversible partial deployment procedure in which a portion of the prosthesis is exposed distal the capsule and allowed to radially expand. Subsequently, with distal advancement of the capsule, the distal zone transitions to the flared state and imparts a collapsing force onto the prosthesis, causing the prosthesis to radially collapse and become recaptured within the delivery capsule. The capsule can include a laser cut tube encapsulated by a polymer.
