Abstract: An implantable device includes an adjustable spacer and at least one anchor. The adjustable spacer is configured to be positioned between native heart valve leaflets to reduce regurgitation therebetween. The adjustable spacer can comprise a first side and a second side opposite the first side. Each side can be adjustable between a first width and a second width. Each side can be independently moved between the first width and the second width. The adjustable spacer can be made from a sponge material.

Abstract: Disclosed herein are catheter control handles that include various mechanisms for controlling the circumferential angle and radial magnitude of flexion of an attached catheter. Control handles can comprise a housing. Control wires extend from a distal end of the housing and into a steerable transluminal device. A flex control member is operable to control tension on the pull wires to adjust a magnitude of radial flexion of the steerable transluminal device. A position control member is operable to control tension on the pull wires to adjust a circumferential angle in which the radial flexion of the steerable transluminal device is directed.

Abstract: A stabilizing apparatus for a transcatheter delivery system includes a housing having an aperture to receive the transcatheter delivery system. An engagement member is disposed in the housing. A biasing element urges the engagement member against a surface of the transcatheter delivery system when the transcatheter delivery system is placed in the housing.

Abstract: A valve repair delivery handle includes a housing, an actuation control mechanism, and a clasp control mechanism. The actuation control mechanism includes a knob and an actuation tube. The knob is rotatably coupled to the housing. The actuation tube is coupled to the knob such that rotation of the knob in a first direction moves the actuation tube distally relative to the housing and rotation of the knob in a second direction moves the actuation tube proximally relative to the housing. The clasp control mechanism is coupled to the housing.

Abstract: A valve repair system for repairing a native valve of a patient includes a catheter and a valve repair device. The valve repair device is disposed in the catheter. The valve repair device comprises a compressible spacer and a pair of paddles. The pair of paddles are moveable between an open position and a closed position. The valve repair device can transition to a compressed configuration with the compressible spacer between the pair of paddles in the closed position.

Abstract: An exemplary valve repair device for repairing a native valve of a patient has a pair of paddles, a pair of gripping members, and at least one latch member. The paddles are movable between an open position and a closed position. The paddles and/or the gripping members are configured to attach to the native valve of the patient. When the paddles are in the closed position, the latch members latch the paddles in the closed position.

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 base assembly, a pair of paddles, and a pair of gripping members. The base assembly includes a shaft and a coupler attached to the shaft such that the coupler can be moved along the shaft. The paddles are movable between an open position, a closed position and a bailout position. The paddles and the gripping members are configured to attach to the native valve of the patient. Movement of the coupler along the shaft causes the paddles to move between the open position, the closed position, and the bailout position. When the paddles are in the bailout position, a bailout angle between each paddle of the pair of paddles and the shaft is greater than or equal to 120 degrees.

Abstract: An implantable prosthetic device can include a spacer member, a plurality of anchors, and a plurality of clasps. The spacer member can be configured to be disposed between native leaflets of a heart. The anchors can be coupled to the spacer member and configured to secure the native leaflets against the spacer member. The clasps can be coupled to a respective anchor and configured to secure the native leaflets to the anchors. The clasps can be independently movable between an open configuration and a closed configuration.

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 surgical delivery instrument, a valve repair device, and a gripper control mechanism. The surgical delivery instrument has at least one lumen. The valve repair device is configured to be delivered through the lumen of the surgical delivery instrument and to be attached to a native valve of a patient. The valve repair device has a pair of paddles, and first and second gripping members. The paddles are movable between an open position and a closed position. The paddles and the first and second gripping members are configured to attach to the native valve of the patient. The gripper control mechanisms each include a suture and a wire having a loop at a distal end. The suture extends from the surgical delivery instrument and through the loop of the wire. The suture is removably attached to the gripping member. The loop of the wire is configured to engage the gripping member to move the gripping member between one or more positions.
