Apparatus and method for delivering surgical tissue connectors into an abdominal cavity and removing the surgical tissue connectors from the abdominal cavity

The present invention is directed to an apparatus and its method of use in delivering surgical tissue connectors into an area of the body and removing the surgical tissue connectors from the body area. Svlore specifically, the present invention is directed to a surgical tissue connector apparatus having at least two tissue connectors connected by a length of cord and a delivery and removal tube. At least one of the tissue connectors has a base with a tapered, beveled or chamfered surface projecting from one end of the base. A hook or other type of tissue connector projects from the opposite side of the base. The hook is positioned on the base where a peripheral side surface of the base shields the hook from unintentionally snagging objects. The base peripheral surface is also dimensioned to slide easily through an interior bore of the tube. This enables the base and the projecting hook to be easily delivered through the tube into an area of the body. The chamfered or tapered surface on the base is positioned to engage with the distal end opening of the tube and direct the base into the center of the tube as the surgical tissue connector is retracted info the tube from the body area in removing the apparatus from the abdominal cavity.

SUTURING DEVICES AND METHODS FOR SUTURING AN ANATOMIC STRUCTURE

20170304051 · 2017-10-26 · ·

A system for repairing an atrioventricular valve of a patient is provided. First and second tissue-engaging elements are configured for implantation at first and second implantation sites of the patient, respectively. First and second flexible longitudinal members are coupled at respective first end portions thereof to the first and the second tissue-engaging elements, respective. Each of the first and the second flexible longitudinal members comprises a braided polyester suture or a plurality of wires that are intertwined to form a rope structure. First and second flexible-longitudinal-member-coupling elements are coupled to respective second end portions of the first and the second flexible longitudinal members. The first and the second flexible-longitudinal-member-coupling elements are configured to be couplable together during an implantation procedure to couple together the first and the second flexible longitudinal elements.

COAPTATION ENHANCEMENT IMPLANT, SYSTEM, AND METHOD
20170265995 · 2017-09-21 ·

Implants, implant systems, and methods for treatment of mitral valve regurgitation and other valve diseases generally include a coaptation assist body which remains within the blood flow path as the leaflets of the valve move, the valve bodies often being relatively thin, elongate (along the blood flow path), and/or conformable structures which extend laterally from commissure to commissure, allowing the native leaflets to engage and seal against the large, opposed surfaces on either side of the valve body during the heart cycle phase when the ventricle contracts to empty that chamber of blood, and allows blood to pass around the valve body so that blood flows from the atrium to the ventricle during the filling phase of the heart cycle. Separate deployment of independent anchors near each of the commissures may facilitate positioning and support of an exemplary triangular valve body, with a third anchor being deployed in the ventricle. An outer surface of the valve body may accommodate tissue ingrowth or endothelialization, while a fluid-absorbing matrix can swell after introduction into the heart. The valve body shape may be selected after an anchor has been deployed, and catheter-based deployment systems may have a desirable low profile.

Systems and methods for introducing elements into tissue

A system is provided for delivering respective anchors into spaced apart locations along an annulus of a mitral valve. The system includes a first catheter member having a first lumen formed therein for receiving a first guide wire and also includes a second catheter member that is configured to move between an expanded position and a collapsed position relative to the first catheter member. The second catheter member has a lumen formed therein for receiving a second guide wire when the second catheter member is in the expanded position. The second catheter member is fixedly connected to the first catheter member by a first connector (that defines first and second living hinges) which is configured to deploy under a select condition to automatically cause the second catheter member to move to the expanded position.

Hand operated device for controlled deployment of a tissue anchor and method of using the same

A tissue anchoring system includes a tissue anchor member that is suitable for anchoring against tissue. The system also includes a tensioning member operatively connected to the anchor member such that the anchor member can slide relative to the tensioning member, the tensioning member capable of being pulled to cause the anchor member to move relative to the tensioning member into a position seated against the tissue. A hand operated deployment catheter is operable to extend and deploy the anchor member therefrom. The deployment catheter includes a rotatable member about which the tensioning member is routed and a clutch assembly for limiting tension within the tensioning member to prevent the deployed anchor from being pulled through the tissue.

TOOL FOR ACTUATING AN ADJUSTING MECHANISM

A method is provided including inserting into a heart a tissue-adjusting member selected from the group consisting of: one or more artificial chordae tendineae and an annuloplasty ring structure. An adjusting mechanism of the tissue-adjusting member adjusts tension of the tissue-adjusting member. The adjusting mechanism: (a) includes a locking mechanism configured to restrict adjusting of the tissue-adjusting member by the adjusting mechanism, and (b) is shaped to define a first coupling. The method further includes, using a tool reversibly coupled to the adjusting mechanism, restricting the adjusting of the tissue-adjusting member by the adjusting mechanism, by facilitating movement of the locking mechanism into a locked state. The tool is shaped to define a second coupling that mates with the first coupling of the adjusting mechanism. The first and second couplings are coupled together and remain mated during the restricting of the adjusting of the tissue-adjusting member.

DEVICES, SYSTEMS, AND METHODS FOR RESHAPING A HEART VALVE ANNULUS

Anchors for securing an implant within a body organ and/or reshaping a body organ are provided herein. Anchors are configured for deployment in a body lumen or vasculature of the patient that are curved or conformable to accommodate anatomy of the patient. Such anchors can include deformable or collapsible structures upon tensioning of a bridging element in a lateral direction, or segmented tubes that can be adjusted by tightening of one or more tethers extending therethrough. Such anchors can be used as a posterior anchor in a blood vessel in implant systems having a tensioned bridging element extending between the posterior anchor and an anterior anchor deployed at another location within or along the body organ. Methods of deploying such anchors, and use of multiple anchors or multiple bridging elements to a single anchor are also provided.
