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.

Transcatheter prosthetic heart valve post-dilatation remodeling devices and methods

Systems and methods for delivering and implanting heart valves are disclosed. The delivery systems can include an integrated introducer. The integrated introducer can include a sheath having an inner diameter that is smaller than the outer diameter of a delivery capsule of the delivery system and an outer diameter that is approximately equal to the outer diameter of the delivery capsule. The integrated introducer can include a hub having a hemostatic seal. The hub can have a locking mechanism configured to fix the integrated introducer in place on the delivery system.

Delivery system with inline sheath

A fluid infusion device and related operating methods are disclosed. The fluid infusion device has a housing, a fluid pump mechanism having an inlet and an outlet, a first flow path in fluid communication with the inlet and at least partially defined by structure compatible with fluid cartridge modules containing medication fluid, a second flow path in fluid communication with the outlet and terminating at a subcutaneous conduit for a body, and a drive motor that actuates the pump mechanism. An exemplary operating method detects a first installation of a fluid cartridge module in the housing. The detecting occurs after the housing has been affixed to the body and after the subcutaneous conduit has been inserted into the body. In response to the detecting, the operating method initiates an automatic priming operation to prepare the device for delivery of the medication fluid to the body.

Fluid infusion patch pump device with automatic fluid system priming feature

A fluid infusion device and related operating methods are disclosed. The fluid infusion device has a housing, a fluid pump mechanism, a transcutaneous conduit assembly having a fluid conduit coupled to the pump mechanism, and an insertion mechanism for inserting the conduit into the body. An exemplary method begins by detecting a first installation of a fluid cartridge module in the housing, wherein the detecting occurs after the housing has been affixed to the body. In response to the detecting, the operating method automatically activates the insertion mechanism to insert the fluid conduit into the body.

Fluid infusion patch pump device with automatic startup feature

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. Methods of deploying the stent with the delivery system are also disclosed.

Attachment mechanism for stent release

A fluid infusion device and an insertion mechanism are disclosed. The insertion mechanism actuates an assembly having a fluid conduit and a needle. An embodiment of the insertion mechanism includes a first sliding block, a second sliding block, a torsion spring, and a living hinge. The first block is coupled to the conduit to move the conduit in an insertion direction. The second block is coupled to the needle to move the needle in the insertion direction and in a retraction direction, wherein movement of the second block in the insertion direction pushes the first block in the insertion direction. The living hinge is coupled between the torsion spring and the second block. Rotation of the torsion spring during an insertion action actuates the living hinge to move the second block in the insertion direction and, thereafter, in the retraction direction.

Transcutaneous conduit insertion mechanism with a living hinge for use with a fluid infusion patch pump device

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.

Transcatheter prosthetic heart valve delivery device with release features

An attachment mechanism for coupling a stent to a delivery system is disclosed. The delivery system includes an inner shaft assembly. The attachment mechanism is configured to pivot relative to the inner shaft assembly of the delivery system in order to release the stent from the delivery system upon retraction of a delivery sheath capsule compressively containing the stent.

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.

Stented transcatheter prosthetic heart valve delivery system and method

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.

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.
