20110098804 | STENTED TRANSCATHETER PROSTHETIC HEART VALVE DELIVERY SYSTEM AND METHOD - 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. | 04-28-2011 |
20110264201 | Transcatheter Prosthetic Heart Valve Post-Dilatation Remodeling Devices and Methods - A system and method for restoring (e.g., replacing) a defective heart valve of a patient. A delivery system is manipulated to percutaneously deliver and implant a stented prosthetic heart valve to a native heart valve. A post-dilatation balloon is percutaneously delivered to the implantation site, and a compliant segment thereof is arranged within a region of the implanted prosthesis. The balloon is inflated such that the compliant segment expands and contacts the prosthesis, expanding a remodeling region of the prosthesis to a remodeled state. With these and related techniques, remodeling of an implanted, stented prosthetic heart valve to better match the native valve shape is possible, providing many benefits such as reducing the risk of paravalvular leaks. | 10-27-2011 |
20120022628 | Attachment Mechanism for Stent Release - An attachment mechanism for coupling a stent to a delivery system is disclosed. The attachment mechanism is configured to pivot relative to an inner shaft assembly of the delivery system in order to release the stent from the delivery system. | 01-26-2012 |
20120103985 | SINGLE UNIT DISPENSING CAP - A cap for a container configured for dispensing single items, such as pills, held in said container. The cap channel extends from an upper surface to a lower end providing a passageway through the cap to allow for a predetermined quantity of items to be transferred through a port in an upper portion of the cap. The cap has a lid moveable from a closed position to an open position. In its closed position dispensing of items is prevented; in its open position at least one item is dispensed through the port. A gate is operable, in a first orientation to partially block the passageway and, in a second orientation, to unblock the passageway to allow a preset number of items, to pass through. Alternatively, a diverter is incorporated to control flow of the contents. | 05-03-2012 |
20120303111 | Attachment Mechanism for Stent Release - An attachment mechanism for coupling a stent to a delivery system is disclosed. The attachment mechanism is configured to pivot relative to an inner shaft assembly of the delivery system in order to release the stent from the delivery system. | 11-29-2012 |
20130274855 | Transcatheter Prosthetic Heart Valve Delivery Device With Release Features - A delivery system for percutaneously delivering and deploying a stented prosthetic heart valve. The delivery device includes a delivery sheath slidably disposed over an inner shaft, and a capture assembly. The capture assembly includes at least one release feature for releasing the stented prosthetic heart valve from the delivery device. | 10-17-2013 |
