Appl. No.:

09/409332

Inventors:

Norman S. Gordon - Irvine CA

Richard L. Quick - Trabuco Canyon CA

Assignee:

Scimed Life Systems, Inc. - Maple Grove MN

International Classification:

A61B 1704

US Classification:

606144, 606139, 606147

Abstract:

A method and device for the placement of sutures and for the purpose of approximating tissue. The invention relates to devices for approximation, ligation and fixation of tissue using a suture, to various constituent parts comprising said devices, and particularly to the placement of sutures into certain difficult to access ligamental structures, to the approximation of tissue separated by means of an endosurgical trocar being inserted into a body cavity, and to approximation, ligation, and fixation of body tissue using both traditional open surgical and endosurgical techniques and instruments. The invention provides for the loading of suture material including needles into the device, introduction and placement of the device into the body cavity, with the distal end having deployable needle guides, extending the needle guides either simultaneously or individually to the periphery of the wound, engaging the wound with the needle guides, driving the needles and suture material through the tissue to be approximated into a catch mechanism, retracting the needle guides and withdrawing the device, leaving a loop of suture material in the margin of tissue. The suture may then be tied to approximate the wound and excess suture material cut off. The invention also provides for the placement of sutures for the endoscopic approximation, fixation, and ligation of tissues within a body cavity including the driving and retrieval of needle and suture combinations, and facilitating the tying of knots.

Assignee:

Opus Medical, Inc. - San Juan Capistrano CA

International Classification:

A61B 1704

US Classification:

606151, 606232

Abstract:

A bone anchor device for attaching connective tissue to bone comprises a disk adapted for insertion into a portion of bone to which the connective tissue is to be attached. The disk is movable between a bent orientation for presenting a smaller cross-section and an expanded orientation for presenting a larger cross-section. The bent orientation is utilized for inserting the disk through a small hole into a region of cancellous bone beneath the cortical bone layer, after which the disk is actuated to its expanded orientation so that it will be permanently anchored in the cancellous bone, as it will be too large to return proximally through the hole in the cortical bone layer. Two embodiments are disclosed. In a first embodiment, the disk is initially formed in the expanded orientation, of spring steel. In a second embodiment, the disk is initially formed in the bent orientation, and spring steel is not required.

Assignee:

Opus Medical, Inc. - San Juan Capistrano CA

International Classification:

A61B 1756

US Classification:

606 72, 411 34

Abstract:

A bone anchor and methods for using same to secure connective tissue, such as tendons, to bone are disclosed which permit a suture attachment that lies entirely beneath the cortical bone surface. The bone anchor of the invention incorporates a deformable body that creates an increased anchor body diameter after it is inserted into the cancellous bone and deployed beneath the cortical surface of the bone. The increased body diameter, by virtue of its intrinsic geometry, creates both axial and rotational fixation of the bone anchor or suture fixation point.

International Classification:

A61B 1704

US Classification:

606144

Abstract:

A suturing instrument for placing mattress stitches in soft tissue, such as a rotator cuff, includes an elongate shaft with both a stationary jaw and a movable jaw disposed at the distal end thereof. The shaft is coupled to a handle grip at the proximal end, which is configured to manipulate the jaws into open and closed positions. The jaws are configured to allow for atraumatic grasping of soft tissues. The stationary jaw may include a molded tip that holds and positions opposite ends of a single strand of suture material. The serrated upper jaw is configured to grasp and immobilize the tissue to be sutured. Hooked needles are movably positioned to pierce the grasped and immobilized tissues, and to engage and retrieve the opposite ends of the single strand of suture material. The handle is released to open the moveable jaw, whereupon the instrument may be withdrawn, trailing the suture, and leaving a mattress stitch in the grasped tissue.

International Classification:

US Classification:

606232, 606 72, 606 74

Abstract:

An innovative bone anchor and methods for securing soft tissue, such as tendons, to bone, which permit a suture attachment that lies entirely beneath the cortical bone surface. Advantageously, the suturing material between the soft tissue and the bone anchor is secured without the need for tying a knot. The suture attachment to the bone anchor involves the looping of a length of suture around a pulley within the bone anchor, tightening the suture and attached soft tissue, and clamping the suture within the bone anchor. The bone anchor may be a tubular body having a lumen containing a plurality of suture-locking elements that clamp the suture therein. The locking elements may be thin and C-shaped. One or more locking plugs attached to separable actuation rods displace axially within the lumen and act on the locking elements to displace them radially. A generally uniform passage through the locking elements in their first positions converts to a smaller irregular passage after the locking plug displaces the elements to their second positions, thus effectively clamping the suture.
