  • Publication number: 20090228041
    Abstract: An arthroscopic meniscal tear repair device comprises a catch needle and a transfer needle. which are pierced into a torn meniscus and advanced past the tear. Suture is transferred by a suture needle from the transfer needle through the meniscus and into the catch needle. The catch needle has an internal mechanism that retains the suture. The suture needle is then retracted back to its home position inside the transfer needle, leaving the free end of the suture across the meniscus and in the catch needle. The device is then retracted out of the meniscus, leaving behind a stitch across the meniscal tear inside the meniscus. A pre-tied knot of suture is then slid down the device and cinched up using a knot pusher having a dilation tip, thus completing the repair.

  • Publication number: 20080081942
    Abstract: Devices and methods for treating degenerative, congestive heart disease and related dysfunction are described. Passive and active cardiac support structures mitigate changes in ventricular structure (i.e., remodeling) and deterioration of global left ventricular performance related to tissue damage precipitating from ischemia, acute myocardial infarction (AMI) or other abnormalities. Cardiac efficiency is improved by providing reinforcement that restores or maintains an elliptical ventricular shape and mimics the position and positive inotropic effects of helical wound myofibrils to provide active contraction of the ventricle in synchrony with the metabolically required cardiac pace or output. In addition, the cardiac support structures compensate or provide therapeutic treatment for congestive heart failure and/or reverse the remodeling that produces an enlarged heart.

  • Publication number: 20080077162
    Abstract: A system and method for repairing soft tissue comprises introducing an instrument having a shaft into an operative site, such as a human shoulder. Then, a flexible grasper is advanced from the instrument to capture a portion of soft tissue. The flexible grasper is then retracted so that the captured tissue lies in a pathway for a needle in the instrument. The needle is advanced along the pathway through the captured tissue, and then a portion of suture is captured with the needle, distally of the captured tissue. The needle is retracted proximally through the captured tissue, to thereby pass the suture therethrough and plicate the tissue. The plicated tissue is then released from the grasper.

  • Publication number: 20080058864
    Abstract: Apparatus for sealing a puncture includes an elongate occlusion member having a balloon attached to distal ends of telescoping inner and outer members. A housing on the proximal end of the outer member includes a piston coupled to the inner member and slidable within a chamber communicating with a fluid reservoir. A switch on the housing is actuated to direct fluid from the reservoir through the outer member into the balloon to expand the balloon and into the chamber to move the piston and pull the inner member, shortening the balloon as it expands. During use, the distal end of the occlusion member is introduced into a puncture communicating with a vessel until the collapsed balloon is disposed within the vessel. The balloon is expanded, and a tensioner is connected to the housing to apply a proximal force holding the balloon against the vessel wall to seal the puncture.

  • Publication number: 20070186933
    Abstract: A method and system for catheter-based delivery of implants in the body. Implants can include stents, plugs, coils, baskets, filters, valves, grafts, prosthesis', drugs, drug reservoirs, biologics, or pumps. The catheter system comprises a uniquely configured grasper mechanism that allows holding the implant during the unsheathing delivery step prior to full release. With this delivery system, the implant can be unsheathed, positioned, and the position can be evaluated prior to releasing the implant from the catheter. Upon evaluation of the position of the implant, if it is found to be inaccurately placed, then removal of the implant can be done easily and without a device exchange. If the implant is found to be positioned correctly, the grasper mechanism can be actuated to release the implant from the catheter.

  • Patent number: 7144363
    Abstract: Described are devices and methods for treating degenerative, congestive heart disease and related valvular dysfunction. Percutaneous and minimally invasive surgical tensioning structures offer devices that mitigate changes in the ventricular structure (i.e., remodeling) and deterioration of global left ventricular performance related to tissue damage precipitating from ischemia, acute myocardial infarction (AMI) or other abnormalities. These tensioning structures can be implanted within various major coronary blood-carrying conduit structures (arteries, veins and branching vessels), into or through myocardium, or into engagement with other anatomic structures that impact cardiac output to provide tensile support to the heart muscle wall which resists diastolic filling pressure while simultaneously providing a compressive force to the muscle wall to limit, compensate or provide therapeutic treatment for congestive heart failure and/or to reverse the remodeling that produces an enlarged heart.

  • Publication number: 20060155287
    Abstract: Devices, systems and methods for fixation of tendon to bone are described. An exemplary surgical implant is a modified bone anchor that is able to grasp the tendon and hold it firmly in a bone tunnel. Once deployed, the anchor delivers lateral compression to the tendon, providing direct tendon to bone compression to facilitate healing. The anchor has different versions which allow it to be attached to the tendon prior to insertion into the bone tunnel, or be inserted between tendon arms when the surgical procedure dictates. The resulting tendon to bone compression allows for the firm fixation in a manner markedly simpler than traditional techniques. A modification of this anchor can also allow the anchor to grasp and hold suture. This variation facilitates the technique for knotless rotator cuff repair.
