Heart valve sealing devices and delivery devices therefor
An exemplary valve repair system for repairing a native valve of a patient during a non-open heart procedure includes a delivery device and a valve repair device. The valve repair device includes a pair of gripping members that are configured to attach to the native valve of the patient. A gripper control mechanism is configured to independently engage and move each of the gripping members.
Heart valve sealing devices and delivery devices therefor
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.
Device and method for treating vascular insufficiency
Embodiments of a leaflet clip device and method of reducing regurgitation through a native heart valve are disclosed. A leaflet clip device can include an elongated clipping member having a first end portion and a second end portion and a tensioning mechanism coupled to the clipping member. The leaflet clip device can further include one or more tensioning members disposed within a lumen of the clipping member, wherein the one or more tensioning members are operatively connected to the tensioning mechanism to transform the clipping member from a delivery configuration to an implantation configuration.
Heart valve sealing devices and delivery devices therefor
An exemplary valve repair device for repairing a native valve of a patient includes a pair of paddles, a coaption element, and a covering. The coaption element has a first end portion and a second end portion. The coaption element is connected to the pair of paddles. The covering is disposed over the caption element. The covering prevents blood from flowing through the caption element.
Implantable prosthesis having acellular tissue attachments
Improved prostheses comprising a tissue expander and a graft material are disclosed herein. Also disclosed are methods of making prostheses and methods of treatment using the prostheses.
STENTS WITH INCREASED FLEXIBILITY
Stents that are adapted to be balloon expanded and include adjacent supports connected by connecting portions. The configurations, materials, and/or dimensions of at least one of the supports and connection portions allows the stents to be expanded to a greater extent, and optionally with reduced foreshortening.
Heart valve sealing devices and delivery devices therefor
An implantable prosthetic device includes a coaption portion, paddles, and clasps. The paddles are extendable from a folded closed position to an open position. A clasp is attached to each of the paddles. Each clasp has a fixed arm attached to the inner portion of the paddle and a moveable arm having a barbed portion. A hinge portion connects the fixed arm to the moveable arm. A cover wraps around at least a portion of the moveable arm of the clasp. At least one actuation suture is attached to the cover.
Heart valve sealing devices and delivery devices therefor
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.
Native valve repair devices and procedures
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 having a plurality of pivoting links, a pair of paddles attached to the base assembly, a pair of gripping members attached to the base assembly, and at least one coaptation or spacer element disposed between the pair of gripping members. Movement of the pivoting links of the base assembly causes the paddles to move between an open position and a closed position. The paddles and the gripping members are configured to attach to valve leaflets of the patient. The coaptation or spacer element is configured to fill at least a portion of a gap between the valve leaflets of the patient.
Heart valve sealing devices and delivery devices therefor
An implantable prosthetic has a coaption portion, paddles, and clasps. The paddles are extendable from a folded closed position to an open position. A clasp has a fixed arm attached to the paddle. The clasps also have a moveable arm having a barbed portion and an end that is rounded. A hinge portion connects the fixed arm to the moveable arm.
