摘要:
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.
摘要:
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.

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.

摘要:
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.

摘要:
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.

A male urinary incontinence device comprises a cylindrical sheath with an open first end to receive the penis and a tubular connector at a second end for discharge of collected urine, the sheath having a longitudinal opening along at least one side to allow ready placement of the penis therein. A viscous gel strip is applied to the upper inner circumference of the sheath and an elastic strap is applied to the upper outer circumference of the sheath the gel strip and strap acting cooperatively to retain the sheath on the penis and to render the sheath leak proof in use. The sheath also includes a connector assembly for attachment of tubing and a urine collection vessel. Placement of the device may also include a mounting ring and a strap assembly.
