Abstract: A prosthetic implant delivery assembly can include a prosthetic implant and an elongate catheter. The prosthetic implant can include an expandable stent portion having a longitudinal axis extending from a first end portion of the stent to a second end portion of the stent. The catheter can include a longitudinal axis extending from a proximal end portion of the catheter to a distal end portion of the catheter and a plurality of arms extending axially from the distal end of the catheter. The first end portion of the stent can be releasably and pivotably coupled to at least one the arms of the catheter such that the stent can pivot about the at least one of the arms so that the longitudinal axis of the stent is tilted relative to the longitudinal axis of the catheter.

IPC: A61F2/24

Abstract: A system for implanting a repair device onto a native valve of a natural heart to repair the native valve of a patient during a non-open-heart procedure. The system includes a pair of paddles and a pair of gripping members. The paddles are movable between an open position and a closed position. The paddles and the gripping members are configured to attach to the native valve of the patient. The paddles are biased to the closed position, latched to the gripping members in the closed position, maintained in the closed position by a threaded connection, or otherwise maintained in the closed position.

Abstract: A pair of paddles are moved laterally away from one another in an exemplary method of repairing a native valve of a patient during a non-open-heart procedure. After the paddles are moved laterally away from one another, first and second gripping members are moved from an open position to a closed position to grasp valve leaflets. The paddles are then moved laterally toward one another. A cam can be used to move the paddles away from one another.

Abstract: An exemplary valve repair device is released from tissue of a valve of a patient by applying tension to a movable arm of a clasp in a retraction direction. A fixed arm of the clasp is attached to an inner paddle portion of a paddle of the valve repair device. The inner paddle portion is connected to an outer paddle portion of the paddle of the valve repair device. Pulling the moveable arm of the clasp flexes the inner paddle portion to allow the moveable arm to move in the retraction direction and thereby release the clasp from the valve tissue.

Abstract: An exemplary implantable prosthetic device has a paddle frame, an inner paddle, and an outer paddle. The outer paddle is connected to the inner paddle. The inner and outer paddles are connected to the paddle frame at a connection between the inner paddle and the outer paddle. The paddle frame can be positioned inside the inner paddle, outside the outer paddle, or between the inner and outer paddles.

Abstract: A system for implanting a repair device onto a native valve of a natural heart to repairing the native valve of a patient during a non-open-heart procedure. The system includes a pair of paddles and a pair of gripping members. The paddles are movable between an open position and a closed position. Each of the gripping members has a barbed portion for securing the gripping members to the native valve of a patient. Each gripping member is slidably attached to a corresponding paddle. Each gripping member can be moved in a first direction along the paddle before the barbed portion of the gripping member pierces the native valve of the patient. Each gripping member can be moved in a direction substantially opposite the first direction after the barbed portion pierces the native valve of the patient such that the gripping members create a tensioning force on the native valve of the patient.

Abstract: A valve repair device for repairing a native valve of a patient includes a pair of paddles and an expanding spacer. The paddles are movable between an open position and a closed position. The expanding spacer is disposed between the pair of paddles. The expanding spacer is configured to be expanded between the paddles when the paddles are moved from the open position to the closed position. The expanding spacer is configured to fill at least a portion of a gap in the native valve of the patient when the valve repair device is attached to the native valve and the expanding spacer is expanded.

Abstract: Certain embodiments of the present disclosure provide a prosthetic valve (e.g., prosthetic heart valve) and a valve delivery apparatus for delivery of the prosthetic valve to a native valve site via the human vasculature. The delivery apparatus is particularly suited for advancing a prosthetic heart valve through the aorta (i.e., in a retrograde approach) for replacing a diseased native aortic valve. The delivery apparatus in particular embodiments is configured to deploy a prosthetic valve from a delivery sheath in a precise and controlled manner at the target location within the body.
