  • Patent number: 7083638
    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 compressing the suture against the bone anchor. The bone anchor may be a tubular body having a lumen with a locking plug that compresses the suture therein. The pulley may be a pin located near a distal end of the tubular body around which the length of suture is looped. Alternatively, a pulley may be a bridge portion of the tubular body between two spaced apertures in the wall of the body. The locking plug may include a shaft and an enlarged head that interferes with the tubular body to provide a positive stop.

  • Patent number: 6953468
    Abstract: A method as provided for occluding the vasculature of a patient. The method comprises the steps of providing a plurality of embolic coils having a textured surface. The embolic coils are introduced into the patient's vasculature. In this manner, the textured surface provides improved platelet adhesion compared to a non-textured surface, to promote clotting. In the illustrative embodiment, the embolic coil comprises a platinum-tungsten alloy wire and the texturing is performed by abrasion or sandblasting to provide substantially uniform roughness comprising pockets having diameters of about 0.125 microns to about fifty microns and depths of about 0.25 microns to about twenty microns.

  • Patent number: 6916327
    Abstract: A surgical staple for use in creating an everted anastomosis of at least two anatomical structures includes a bendable staple body. At least two evening elements protrude from the staple body. Spacing elements and a penetrating element also are provided. In use, the evening elements and spacing elements are apposed, and inner layers of the anatomical structures are held together to form an evened anastomosis. The evening platforms are disposed on an outer radius of the closed staple, and the penetrating element is disposed on a different, inner radius, to ensure that the penetrating element is excluded from the lumen of the anastomosis. Embodiments of the invention substantially ensure intima-to-intima approximation completely circumferentially at the anastomotic site, with no portion of cut tissue edges, suture or staple exposed to the lumen of the anastomosis. Cut tissue edges, as well as the staple, are completely extra-lumenal. Related methods provide similar advantages.

  • Patent number: 6890338
    Abstract: Anastomosis devices, methods and apparatus for installing the devices in the performance of an anastomosis. One example of a device includes a central ring portion from which malleable tines and optionally also fastener elements extend. Each tine may have a weakened section at which it preferentially folds or buckles when subjected to bending force. Each tine can grab and evert tissue around an orifice in which it is installed, as it is moved from an initial to a final configuration. To install a device, the tines are advanced against an anvil to cause them to grab tissue around the orifice and curl radially. The anvil is then retracted to fold the tines so their curled ends move radially outward.

  • Patent number: 6818001
    Abstract: The intralumenal material removal system includes a cutter assembly positionable in the lumen of a mammalian subject and operably connected to system controls. The cutter assembly is axially advanceable by translating the drive shaft and rotatable by rotating the drive shaft. One cutter assembly comprises an adjustable cutter that is adjustable between a smaller diameter condition and a larger diameter condition by rotation of the drive shaft in opposite directions. The cutter may thus be introduced to and withdrawn from the material removal site in a retracted, smaller diameter condition that facilitates translation and navigation of the device through various lumens. The adjustable cutting assembly may be selectively expanded at the material removal site to facilitate cutting, removal and aspiration of the occlusive material. One composite cutter assembly comprises both a distal, fixed diameter cutter and a proximal adjustable diameter cutter.
