  • Publication number: 20060064116
    Abstract: The present invention is directed to an apparatus and method for the stabilization and fastening of two pieces of tissue. A single device may be used to both stabilize and fasten the two pieces of tissue, or a separate stabilizing device may be used in conjunction with a fastening device. The stabilizing device may comprise a probe with vacuum ports and/or mechanical clamps disposed at the distal end to approximate the two pieces of tissue. After the pieces of tissue are stabilized, they are fastened together using sutures or clips. One exemplary embodiment of a suture-based fastener comprises a toggle and suture arrangement deployed by a needle, wherein the needle enters the front side of the tissue and exits the blind side. In a second exemplary embodiment, the suture-based fastener comprises a needle connected to a suture. The needle enters the blind side of the tissue and exits the front side. The suture is then tied in a knot to secure the pieces of tissue.

  • Publication number: 20050267493
    Abstract: The present system is directed to a method and system to stabilize and repair tissue. At least two opposing devices may be used to stabilize and repair the tissue, with the two devices cooperatively engaging the tissue interposed therebetween. Stabilization may be accomplished by opposing force, vacuum force, or mechanical devices disposed at the distal portion of one or both devices. After the tissue has been stabilized, fasteners may be deployed into the tissue. Fasteners include sutures, clips, and staples. Also disclosed is a minimally invasive method of accessing tissue located within a body and conducting a repair of the area using the system disclosed herein.

  • Publication number: 20050085746
    Abstract: An introducer assembly for inserting a medical device into a body passage. The introducer assembly includes an elongate, tubular and retractable inner sheath formed of a deformable and flexible material. The introducer assembly further includes an inner core removably inserted through and secured to the inner sheath. A lumen within the inner core may serve as a channel for accommodating a guidewire. The introducer assembly is configured with a minimized outer diameter that avoids sheath kinking during insertion in the body passage while utilizing a thin flexible inner sheath capable of accommodating large-diameter catheters. A method for inserting a medical device through the introducer assembly is disclosed.
