  • Patent number: 6994715
    Abstract: Intra-gastric fastening devices are disclosed herein. Expandable devices that are inserted into the stomach of the patient are maintained within by anchoring or otherwise fixing the expandable devices to the stomach walls. Such expandable devices, like inflatable balloons, have tethering regions for attachment to the one or more fasteners which can be configured to extend at least partially through one or several folds of the patient's stomach wall. The fasteners are thus affixed to the stomach walls by deploying the fasteners and manipulating the tissue walls entirely from the inside of the organ. Such fasteners can be formed in a variety of configurations, e.g., helical, elongate, ring, clamp, and they can be configured to be non-piercing. Alternatively, sutures can be used to wrap around or through a tissue fold for tethering the expandable devices. Non-piercing biased clamps can also be used to tether the device within the stomach.

  • Patent number: 6939364
    Abstract: Consistent with the present invention, tissue adhesive compositions and an associated laser exposure system are provided for bonding or sealing biological tissues. The compositions are comprised of chemically derivatized soluble collagen which is formulated to concentrations ranging from 300 mg/ml (30%) to 800 mg/ml (80%) collagen protein. In particular, Type I collagen, for example, is first prepared by extraction from bovine or porcine hide and purified. The collagen preparations are then chemically derivatized with sulfhydryl reagents to improve cohesive strength and with secondary derivatizing agents, such as carboxyl groups, to improve the adhesive strength of the solder to the tissue. The compositions are then formed into viscous solutions, gels or solid films, which when exposed to energy generated from an infrared laser, for example, undergo thermally induced phase transitions.

  • Patent number: 6936055
    Abstract: This is a device for bridging the neck of either a wide-necked or narrow-necked aneurysm in the vasculature. In general, it is a device used to stabilize the presence of vaso-occlusive devices (such as helically wound coils) in the aneurysm. The device preferably is delivered by a core wire which terminates in an electrolytically severable joint. The core wire will often be insulated. The retainer assembly itself is also attached to the electrolytic joint and typically has a number of array elements which are intended to be resident within the aneurysm after the device is deployed from the distal end of a catheter. After deployment of this retainer, the aneurysm is at least partially filled with a vaso-occlusive device such as helically wound coils.

  • Patent number: 6932824
    Abstract: The present invention relates to a three-needle type vascular closure system. The closure system utilizes three needles in the form of a guiding device, an expandable needle, and a hooking device. The guiding device is used to make the initial opening in the vessel, where the opening provides access for a sheath through which a medical procedure is to be performed. The expandable needle is inserted into the vessel in which it expands radially from the needle to form a target. The hooking device is also inserted into the vessel and is used to hook the expandable needle so as to form an internal union between the hooking device and the expandable needle. The needles can then be retracted thereby extending a suture from the hooking device and forming an internal suture pass that can be used to approximate the tissue surrounding the initial opening in the vessel. In one embodiment, the suture is passed across the vessel opening prior to dilation of the vessel opening.

  • Patent number: 6926727
    Abstract: A surgical blade is disclosed for use with a surgical tool for making incisions in the sclera of an eye to form a scleral pocket to receive a scleral prosthesis. The surgical blade comprises a rotatable support arm capable of being rotated by the surgical tool and a detachable curved cutting blade for making incisions in the sclera of an eye. The surgical tool causes the curved cutting blade to advance through the sclera to form an incision having dimensions to receive a scleral prosthesis. When the incision is complete the curved cutting blade is detached from the rotatable support arm. The curved cutting blade is then removed from the incision by pulling the curved cutting blade forward out of the incision. The incision has the exact dimensions to receive a scleral prosthesis.

  • Patent number: 6905504
    Abstract: A tool for performing anastomosis connects two tissue structures end-to-end. An end of each of the two tissue structures is sized to a known interface dimension with a tissue preparation device, and two or more cuts are made in that end to create at least two flaps. a clamp holds each tissue structure, and each clamp may be integrated with a tissue preparation device. The clamps are movable relative to one another, and are registered together such that the flaps of one tissue structure are pressed against the corresponding flaps of the other tissue structure when the clamps come together. Each flap of one tissue structure is connected to a corresponding flap on the other corresponding tissue structure with at least one connector such as a staple or other fastener.

  • Patent number: 6884251
    Abstract: An anastomosis is performed using a flexible mounting structure mounted on the outside of at least one vessel. Fasteners extend through the vessel and are bent towards the incision to attach the flexible mounting structure to the vessel in a manner that controls the edge of the vessel adjacent to the incision. The mounting structures are oriented on each vessel so fasteners on one mounting structure interdigitate with fasteners on the other mounting structure at the location of contact between the vessels when the two vessels are brought together. This creates two complementary sinusoidal-shaped vessel edges with peaks of one edge being accommodated in the valleys of the other edge. The peak-to-valley orientation forms a sinusoidal-shaped joint which is leak free. The fasteners are spaced so proper pressure is applied to the tissue to promote healing without leaking. Furthermore, the fasteners are sized and shaped to properly engage the tissue and bend in a desired manner.
