Patent number: 6860895Abstract: A tool (101) is provided for inserting and mating two plug members (2, 3) of a sealing device (1) for closing a wound in the wall of a vessel by placing the distal plug member (2) of the sealing device inside the vessel and the proximal plug member (3) on the outside of the vessel. The distal plug member is provided with an elongated retracting means (6) extending from the distal plug member. The tool comprises a gear mechanism (32) coupled to the retracting means for converting a movement of the tool in a proximal direction away from the wound (22), when the distal plug member is anchored in the vessel (20), to a pushing movement for moving the proximal plug member in a direction towards the distal plug member in response to a stretching force in the retracting means.Type: GrantFiled: June 18, 1999Date of Patent: March 1, 2005Assignee: Radi Medical Systems ABInventors: Dan Akerfeldt, Per Egnelov, Fredrik Preinitz

Publication number: 20040267309Abstract: The invention discloses a device and technique for a sutureless wound closure, which limits the risks of rupture and scarring. The device comprises a two-part strap having short hooks or barbs on the ventral surface. The barbs are curved and flexible such that, when urged in one direction, the barbs do not engage while when urged in the opposite direction, the barbs are pushed downward and engage the tissue of the wound. By deploying one strap on each side of the wound, fastening the two straps in the middle of the wound and tightening the ends, the wound is closed. The tension required to close the wound is distributed along the length of the straps, thus resulting in a cleaner, safer closure.Type: ApplicationFiled: June 27, 2003Publication date: December 30, 2004Inventor: Dennis D. Garvin

Patent number: 6669713Abstract: A system including an implantable fastener for fastening layers of tissue is disclosed. In one embodiment, the fastener includes a proximal anchor member and a distal anchor member each being movable from a reduced profile position to a deployed position. The anchor members are mesh structures capable of moving to the deployed position by reducing the axial spacing between opposite ends of the anchor members. Methods of treating gastroesophageal reflux disease (GERD) are also disclosed. One of the methods includes placing the distal anchor member through a hole formed in the wall of the esophagus and through a hole formed in the gastric wall. The distal anchor member and the proximal anchor member are then placed in their deployed positions to fasten the wall of the esophagus and the gastric wall together between the anchor members.Type: GrantFiled: July 23, 2002Date of Patent: December 30, 2003Assignee: SciMed Life Systems, Inc.Inventor: Ronald Adams

Patent number: 6471715Abstract: The present invention relates to a suture tightening wound closure device for use on mammals including humans. This device is comprising a smooth suture (to be sewn across an open wound through the skin and underlying tissue) and a suture loop tension means (for closing the wound). This tension means is by grasping one end of the suture, and pulling back its second end, forming a tensioned suture loop, enclosing the wound. Specifically, the device of the present invention is characterized by the tension means having a manual control mechanism (for pulling or releasing said second end). The smooth suture according to the preferred embodiment of the present invention is a suture band, which is flexible for bending along it's length and is resistant to bending along it's width. The device of the present invention also relates to embodiments having in addition a pair of suture supporting skin reinforcing means.Type: GrantFiled: July 21, 2001Date of Patent: October 29, 2002Assignee: Wisebands LtdInventor: Jerry Weiss

Patent number: 6423087Abstract: An internal organ walls joining instrument for an endoscope is used for endoscopically joining two internal organ walls spaced apart from each other, and for endoscopically forming a fistula between the two internal organ walls. The instrument has at least a first stationary part, a second stationary part, a first line member, a second line member, and a stopper. Each of the first and the second line members is respectively coupled to the first stationary part, the second stationary part, and the stopper. The two internal organ walls are pinched between the first stationary part and the second stationary. The stopper keeps the two internal organ walls in the pinched state. In this state, the fistula is made by an electro-knife. The instrument remains for a certain time until fistula becomes strong, after which it is endoscopically removed.Type: GrantFiled: July 21, 2000Date of Patent: July 23, 2002Assignee: Olympus Optical Co., Ltd.Inventor: Muneo Sawada

Patent number: 6254624Abstract: An external tissue expansion device applies constant continuous low grade force to skin to obtain additional tension free skin and subcutaneous tissue prior to a surgical procedure. The device consists of two suture plates each being laminated structure of steel and an adhesive attached foam cushion. On the each end of one suture plate is a housing that contains a constant force spring placed over a post. The ends of the constant force spring protrude from the housing and there is a hook attached to the end of the constant force spring. On each end of the other suture plate there is a housing, with a opening that can accept the hook of the opposite suture plate. These suture plates are constructed so that they can be manually shaped to conform to the topography of the body part to be corrected and are attached to skin near the defect to be corrected prior to a surgical procedure.Type: GrantFiled: October 6, 1999Date of Patent: July 3, 2001Assignee: Progressive Surgical ProductsInventors: Robert Oddsen, Ralph Ger

Patent number: 6024756Abstract: A catheter delivered device to close a septal defect, the device comprising a cylindrical shaft of metal or polymeric material with concentric parallel cuts through the wall of the device which create flattened support struts. The center of the support struts move radially away from the axis in a hinge like fashion in response to the movement of the device's proximal and distal ends toward the center of the device. This movement is reversibly effected through mechanical means. The device can be coated with growth factors, mitogenic factors or other determinants which can improve tissue growth such that tissue ingrowth can occur over a period of time. The catheter itself may be an ultrasonic imaging catheter.Type: GrantFiled: December 22, 1998Date of Patent: February 15, 2000Assignee: SciMed Life Systems, Inc.Inventors: Joseph Huebsch, Paul J. Buscemi, Thomas J. Holman, Danney Langanki

Patent number: 5893879Abstract: An apparatus for closing wide skin defects may be used with two long interdermal needles configured for insertion underneath skin close to margins of a skin defect. The skin closing apparatus may include two retaining members (70, 71) configured as a flange connecting two legs (20) and forming a U-shaped profile. Each of the legs may include either a sharp book (23) or a blunt skin insertion element at the end of the leg adapted for percing the skin and engaging one of the long interdermal needles. Alternatively, the retaining members may include topical engagement elements for engaging portions of the interdermal needles which are located above the skin surface. A contracting mechanism such as a screw (82) may connect the retaining members and approximate the interdermal needles, while bringing the skin margins together until final closure of the skin defect results.Type: GrantFiled: July 12, 1995Date of Patent: April 13, 1999Assignee: MedChem Products, Inc.Inventors: Bernard Hirshowitz, Amnon Levy, Alexander R.
