Appl. No.:

12/106652

Inventors:

Seth A. Foerster - San Clemente CA, US

Assignee:

ArthroCare Corporation - Austin TX

International Classification:

A61B 17/04

US Classification:

606232

Abstract:

A knotless bone anchor and method for securing soft tissue, such as tendons, to bone, includes a plurality of discrete components. In one variation of the invention, the bone anchor includes a proximal toggle component, an intermediate plug component, and a distal sleeve component. Suture is looped around the plug component and once the anchor is actuated, the suture is compressed between the plug and the sleeve components. Advantageously, one or more of the components may be made of a biocompatible polymer. The polymeric components may be detachably joined to a drive shaft using a plurality of sacrificial fills. The sacrificial fills are broken or severed during deployment of the anchor. Related instruments and methods are also described.

US Classification:

606 74

Abstract:

A surgical tensioning device for holding separated tissues in contact with one another. The device comprises a frame having two opposing first and second sides and a lower surface and an upper surface, and a band for extending around said separated tissues to be held together in conjunction with said frame. The band has two ends attached to the sides of the frame releasably. When the ends are secured to the sides of the frame, the band establishes a path of tension along its length that extends linearly between the two ends of the band.

International Classification:

A61B 18/04

US Classification:

606 28

Abstract:

A device for creating an arteriovenous (AV) fistula comprises an elongate member, a distal member connected to the elongate member and movable relative to the elongate member, and a heating member disposed on at least one of the movable distal member and the elongate member. The distal member comprises structure for capturing tissue to be cut to create the fistula, and the heating member is adapted to cut through the tissue to create the fistula. The elongate member comprises an elongate outer tube. A shaft connects the distal member to the elongate member, and is extendable and retractable to extend and retract the distal member relative to the elongate member.

International Classification:

A61B 18/04
A61B 18/08

US Classification:

606 29, 606 28

Abstract:

A catheter-based device tracks over a guidewire which has been placed from a first blood vessel into a second blood vessel. The distal tip of the catheter is advanced into the second vessel while a proximal member remains in the first vessel. Matching blunt tapered surfaces on each of the distal tip and the proximal member are clamped together, with adjacent walls of each vessel between them, after which a known, controlled pressure is applied between the two surfaces. Heat energy is then applied to the blunt surfaces for approximately 1-30 seconds to weld the walls of the two vessels together. After coaptation of the vessel walls, the heat is increased to then cut through the vessel walls to create a fistula of the desired size.

Assignee:

DALLEN MEDICAL, INC. - San Clemente CA

International Classification:

A61B 17/82

US Classification:

606 74

Abstract:

A tensioning device comprises an elongate member, preferably a band, and a frame having first and second sides. The band has a first end that is attachable to the first side of the frame and a second end that is releasably securable to the second side of the frame. A movable clamping member on the frame secures the second end of the band to the second side of the frame by cinching the second end of the band between an engagement surface on the band and a mating engagement surface on the second side of the frame. A restraining member is provided for restraining the clamping member to a first position spaced from the mating locking surface on the second side of the frame, when the restraining member is in a restraining orientation. The restraining member is movable out of the restraining orientation after the band is tensioned to a predetermined level using the second end. The band is tensioned to the aforementioned predetermined level and is secured to the second side of the frame, so that the band establishes a path of tension along its length that extends linearly between the two ends of the band.

Assignee:

DALLEN MEDICAL, INC. - San Clemente CA

International Classification:

A61B 17/03

US Classification:

606151

Abstract:

A method for repairing separated tissues utilises a tissue tensioner including a locking member, a band, a frame, and a restraining member. One end of the band is attached to a first end of the frame. Tension is applied to the band so that it moves freely between spaced engaging surfaces on the locking bar and a second end of the frame, while a restraining member restrains the locking member to a non-engaging position. Application of a predetermined level of tension on the band causes the restraining member to move to a non-restraining orientation, thereby in turn causing the locking member to move so that its engaging surfaces engage the engaging surfaces of the frame, clamping the band. An alarm is triggered to notify a practitioner that the predetermined level of tension has been achieved and that the restraining member has thus moved to the non-restraining orientation.

International Classification:

A61B 18/04

Abstract:

A device and method for creating an arteriovenous (AV) fistula includes a proximal base having a distal diagonal end surface and a distal tip connected to the proximal base and movable relative to the proximal base. The distal tip has a proximal diagonal end surface. A heating assembly, including an energized heating element, is disposed one of the distal diagonal end surface and the proximal diagonal end surface. A passive heating assembly is disposed on the mating diagonal end surface. The distal diagonal end surface and the proximal diagonal end surface are adapted to contact opposing sides of a tissue portion to create a fistula. The angle of the proximal diagonal end surface matches the angle of the distal diagonal end surface, so that the two surfaces match one another during deployment.
