  • Patent number: 5520701
    Abstract: In order to destroy vascular deformations in the human body, a clamp is provided which is made from titanium. The clamp is expanded in the relieved state and is transferable into the clamping position by a clamping ring, which is displaceable along the clamp in the attached state. The clamp is introduced into the body by a probe, which has a tubular casing and a positioning bar guided therein. The clamp is transferred into the region of the deformation and applied at the application location as a result of the clamping ring being transferred into the clamping position. The transfer is caused by a relative movement between tubular casing and positioning bar. The probe is then released from the positioned clamp.

  • Patent number: 5507798
    Abstract: A method for producing a detachable surgical needle-suture combination of the type incorporating a fluid swellable suture material is capable of producing needle-suture attachments which conform to the prescribed minimum pull-out forces for detachable needle-suture combinations as set forth in the U.S. Pharmacopeia. Generally, the method includes the steps of providing a surgical needle and a fluid swellable suture, immersing an end portion of the suture into a liquid solution whereby the suture end portion swells and assumes an expanded condition, positioning the suture end portion in its expanded condition into an aperture formed in the blunt end of the needle and swaging the blunt end of the needle to cause deformation of at least a portion of the blunt end and engagement with the suture end portion to effect needle-suture attachment.

  • Patent number: 5507754
    Abstract: A method and apparatus for elevating, approximating and/or restraining internal organs or structures, and more particularly for treating female urinary stress incontinence is provided. The invention includes an anchoring device having an elongated suture with an anchor at each end thereof and a cinching member therebetween for adjusting the length of the suture, an apparatus for applying the anchoring device, and an apparatus for drawing the suture relative to the cinching member after it has been emplaced. The method involves securing a first anchor to a first structure, such as the vaginal wall, securing a second anchor to a second structure, such as Cooper's ligament, and drawing the suture relative to the cinching member to approximate the first and second anchors, and thereby move the first structure and the second structure into juxtaposition so as to approximate them.

  • Patent number: 5503634
    Abstract: A device and method are provided for the surgical suturing of narrow incisions that penetrate through a plurality of tissue layers. An elongated, "J"-shaped needle, through which suture material is threaded, is inserted into the wound, bringing the tip through one or more layers of tissue on one side of the wound and pulling suture material up through the wound. After repeating these steps on the other side of the wound, the suture material is knotted. A slidable locking member serves the dual purpose of covering the tip of the suture needle when not in use and also of maintaining pneumoperitoneum.

  • Patent number: 5501692
    Abstract: An instrument for facilitating the use of sutures in laparoscopic surgical procedures includes a hollow housing defining an internal cavity. A plunger extends within the cavity of the housing and is supported therein for relative sliding movement between first and second axial positions. A spring disposed within the cavity urges the plunger to the first axial position relative to the housing. An introducer needle is secured to the housing and extends co-axially therefrom, terminating in an angled tip having a sharp point. An actuator tube is disposed within the introducer needle and is secured to the plunger for axial movement therewith relative to the housing. A flexible wire is disposed within portions of the actuator tube and is secured thereto for axial movement with the plunger. The wire is folded back over itself to form a looped end. When the plunger is in the first axial position, the looped end of the wire is withdrawn within the angled end of the introducer needle.

  • Patent number: 5497933
    Abstract: An apparatus is disclosed for endoscopic application of surgical staples to body tissue in laparoscopic hernia surgery, preferably with surgical mesh. The apparatus includes a staple storage cartridge supported on a pivotal support system at the distal end of the endoscopic section. An elongated pusher system extends from the frame to the endoscopic section and individually advances the staples distally. A pair of legs project distally from the pusher plate to engage the staple during closure to prevent unwanted roll or deformation of the staple. A trigger system actuates the pusher. An anvil structure having rounded anvil legs to match the configuration of the staples provides for individually closing each staple to encompass at least a portion of the surgical mesh and to penetrate the body tissue to attach the portion of the mesh to the body tissue.

  • Patent number: 5486187
    Abstract: In accordance with the present invention, there is provided new and improved apparatuses and methods for anastomosing living vessels. The preferred apparatus includes a ring-like body through which a first living vessel end is extended and everted back over and a second living vessel end which is drawn over the everted first living vessel end to place the lumen of these vessels in apposition. A plurality of fasteners are employed to clinch the vessel ends in sealed apposition at the ring-like body. These preferred fasteners are staple-like and have one leg located inside of the ring-like body but exterior of the first living vessel, and a second leg located exterior of the margin of the second living vessel at the ring-like body. The ring-like body may also be provided with at least one needle-like projection which may be adapted to either permanently impale and hold the vessel ends at the ring-like body or temporarily impale and hold the vessel ends until the fastener are employed.
