International Classification:

A61F 224

US Classification:

623 237

Abstract:

Devices for repairing and replacing a heart valve in various embodiments, the devices include at least first and second support rings connected together in a coiled configuration to abut opposite sides of a valve annulus. A replacement valve may be secured to the coil-shaped device. Various alternative fastening systems include suture fastening systems, mechanical fastening systems, shape memory alloy fastening systems and other fastening systems relying only on the resilience between adjacent coils. A method generally includes inserting a first end of the coil-shaped member through a valve annulus, rotating a first ring of the coil-shaped member into position on one side of the valve annulus and positioning at least a second ring of the coil-shaped member on an opposite side of the valve annulus.

US Classification:

206 633, 206380

Abstract:

A suture package ( ) including a panel having a series of superimposed subpanels ( ). A suture ( ) loops back and forth on the subpanels ( ) such that adjacent loops are retained on adjacent subpanels ( ) and the adjacent subpanels separate the adjacent loops from one another. In the preferred embodiment, an accordion style panel ( ) is utilized and the series of subpanels ( ) are folded into a superimposed relationship. Various features are incorporated to reduce the instances or likelihood of kinking and tangling of the suture ( ) when pulled from the package ( ) by a user.

US Classification:

623 211, 606153, 623 241, 623 2368

Abstract:

A heart valve can be replaced using minimally invasive methods which include a sutureless sewing cuff that and a fastener delivery tool that holds the cuff against the patient's tissue while delivering fasteners to attach the cuff to the tissue from the inside out. The tool stores a plurality of fasteners and is self-contained whereby a fastener is delivered and placed all from inside a vessel. The fasteners are self-forming whereby they do not need an anvil to be formed. Anchor elements are operated from outside the patient's body to cinch a prosthesis to an anchoring cuff of the valve body. The cuff is releasably mounted on the tool and the tool holds the cuff against tissue and drives the fastener through the cuff and the tissue before folding over the legs of the fastener whereby secure securement between the cuff and the tissue is assured. Fasteners are placed and formed whereby fasteners are located continuously throughout the entire circumference of the cuff. A minimally invasive surgical method is disclosed, and a method and tool are disclosed for repairing abdominal aortic aneurysms in a minimally invasive manner.

US Classification:

606/151000, 606/139000

Abstract:

Wire fasteners having legs with lengths that can be one hundred times the width of the fastener are used to secure items, such as prosthesis valves to a patient during minimally invasive surgery. The fasteners are manipulated into position and then are immobilized by means of the legs thereof for tensioning, cutting and forming in situ. The fasteners are manipulated, tensioned and formed from the leg end of the fasteners. Tools for initially placing the fasteners and for immobilizing, tensioning, cutting and bending the fastener legs are disclosed. Once the fasteners are initially placed, the prosthesis is placed on the long legs of the placed fasteners and is guided into position on the legs. Once the prosthesis is in position, the legs of the fasteners are immobilized, tensioned, cut and bent into staple-like shapes to secure the prosthesis to the patient. A method for carrying out the procedure using the long fastener is also disclosed. Using the teaching of the present disclosure, a surgeon can customize a fastener to the particular surgery or even to the particular portion of surgery being performed during the surgery.

US Classification:

606/205000, 606/151000

Abstract:

A clamping and fluid delivery device () for occluding a vessel () during a surgical procedure. Generally, the device () includes an internal core portion () having a distal end () with a sealing surface and opposite side surfaces comprising sealing surfaces. The core portion () is inserted transversely into the vessel (). Opposed, external clamping arms () move together outside the vessel () and clamp the vessel () against the core portion (). Padding () the sealing surfaces on opposite sides of the core portion (), as well as on the distal end () engage the internal walls () of the vessel () and are opposed by padded clamping surfaces () of the arms (). The core portion moves distally simultaneously with the clamping action of the arms to provide a distal seal. A bypass cannula () and cardioplegia cannula () fluidly couple the core portion () to deliver blood and cardioplegia fluid to opposite sides of the core portion ().
