Assignee:

Depuy Mitek, Inc. - New Brunswick NJ

International Classification:

A61B 17/04

US Classification:

606139, 606144

Abstract:

A suturing apparatus comprises a pair of jaws. A bendable needle housed in one of the jaws is adapted to carry a suture. An optional suture receiver may be disposed adjacent to the opposite jaw. A transition block curves the needle and directs it in a direction generally unparallel to an axis of the carrying jaw. The needle may also be configured to retrieve a suture. A retaining mechanism holds a suture in place to be engaged by the needle. The jaw housing the needle may include a lateral opening through which the suture may be inserted. The needle may also include a lateral notch which may be aligned with lateral opening to receive the suture. An actuator coupled to the needle enables the user to move the needle proximally to align the notch with the lateral slot.

US Classification:

417417000, 417416000

Abstract:

A pump cartridge for use in a high pressure fluid jet system is provided. In an exemplary embodiment, the pump cartridge can be adapted to couple to a drive mechanism for driving fluid from a fluid source, through the pump cartridge, to a fluid jet delivery device, and the pump cartridge can be reusable to allow the pump cartridge to be sterilized between uses.

Assignee:

DEPUY MITEK, INC. - Norwood MA

International Classification:

B26D 1/00

US Classification:

083013000

Abstract:

A fluid jet cutting system that provides more consistent cutting jet performance is disclosed. The system includes a fluid pump for pressurizing fluid having a fluid inlet and a fluid outlet. The pump delivers pressurized fluid to a delivery tube that is in fluid communication with an end effector. The end effector includes an orifice for delivering pressurized fluid to tissue. The power delivered to the pump is controlled to produce a desired fluid cutting jet.

US Classification:

606232

Abstract:

A suture anchor assembly includes a suture anchor having a body, the body having a path for threading a suture therethrough. It also includes a suture threader received within the body through the path. The suture threader is an elongated tube having an expanded first end outside of the body adapted to receive suture therein and a closure mechanism for closing the expanded end about the suture whereby to allow the suture to be held by the tube and pulled through the path the load the suture into the body.

US Classification:

606 80, 606 86 R, 606232

Abstract:

Methods and devices are provided for forming bone tunnels. In general, the methods and devices allow multiple converging tunnels to be formed in bone, such as in an arthroscopic surgical procedure, e.g., a rotator cuff repair surgical procedure. One or more sutures can be advanced through the converging tunnels, and the suture(s) can be coupled to tissue. The suture(s) with the tissue coupled thereto can be tensioned, thereby helping to maximize an amount of the tissue in contact with the bone. In an exemplary embodiment, a guide device is provided that can be configured to allow a first tunnel to be formed in bone and to allow a plurality of additional tunnels to be formed in the bone at predetermined angular positions relative to the first tunnel such that each of the additional tunnels can extend transverse to the first tunnel and intersect the first tunnel.
