Abstract
Devices are configured to be positioned within a native heart valve to impede regurgitation through the native heart valve. The devices can have a small size that allows the device to be inserted through a steerable catheter. The steerable catheter extend through a guide sheath. The devices can include adjustable spring closing force. The devices can include biasing members with variable loading and unloading. The devices can include gripping members or clasp members with hinge portions having reduced sizes.
Claims20
A valve treatment device for attaching to a native valve of a patient, the valve treatment device comprising:
- a base;
- one or more paddles pivotably coupled to the base such that one or more paddles are movable between an open position and a closed position;
- an actuation assembly coupled to the base, wherein the actuation assembly is configured to move of the one or more paddles relative to the base such that the one or more paddles move between the closed position and the open position;
- a bias member that engages the actuation assembly to maintain the actuation assembly in a desired position relative to a gap;
- and
- wherein, when the one or more paddles are in the closed position and attached to the native valve of the patient, movement of the valve during a diastolic phase causes the actuation assembly to linearly move within the gap.
A valve treatment device for attaching to a native valve of a patient, the valve treatment device comprising:
- a base;
- one or more paddles pivotably coupled to the base such that the one or more paddles are movable between an open position and a closed position;
- an actuation assembly coupled to the base, wherein the actuation assembly is configured to pivot the one or more paddles relative to the base between the open position and the closed position responsive to the actuation assembly receiving an input;
- one or more clasps coupled to the one or more paddles and having:
- a base portion connected to the one or more paddles,
- a movable arm portion;
- and
- a joint portion connected to the base portion and the movable arm portion, the joint portion comprising one or more joint elements and one or more gaps between the one or more joint elements, and wherein the one or more gaps comprise at least one tapered space.
A valve repair system, comprising:
- a steerable catheter;
- an implant catheter that extends through the steerable catheter;
- a valve repair device coupled to the implant catheter;
- wherein the valve repair device includes one or more paddles that are movable between an open position and a closed position;
- wherein the one or more paddles are each configured to be secured to a native valve leaflet by moving the one or more paddles from the open position to the closed position;
- and
- wherein a passage of the steerable catheter and a size of the valve repair device are configured to allow the valve repair device to slide through the steerable catheter.
