  • Patent number: 6371124
    Abstract: A surgical method for loading ligament grafts into a joint. A longitudinal-socket formed in a bone is intersected by a transverse pin. A flexible strand is drawn with the pin through the bone. A looped portion of the strand is diverted so as to protrude out of the entrance to the longitudinal socket. The ends of the strand remaining accessible on either side of the bone. The ligament graft is captured within the strand loop protruding from the entrance to the socket. The strand is retracted into the socket, drawing the graft into the socket by pulling on the accessible ends of the flexible strand. The graft is fixed in the socket using a transverse implant.

  • Patent number: 6354297
    Abstract: The destruction of undesired fat cells is achieved by use of a device and method whereby apoptosis inducing factors are delivered to undesired fat cells. Adipose inducing factors, such as UV light, IL-1, TNF and dexamethasone are brought into contact with undesired fat cells through the use of an endoscopic device which facilitates conveyance of such factors to such cells. Repeated delivery of such adipose inducing factors can be achieved by having fiberoptic fibers and/or conveyance tubes left beneath a patient's skin in contact with undesired fat.

  • Patent number: 6347632
    Abstract: A method of creating a simulated aorta patterned from a natural aorta and having a preselected amount of compliance is disclosed. The dimensions of a simulated aortic root patterned according to the dimensions of a natural aorta are first selected and a mold provided. The amount of circumferential compliance desired in the simulated aorta is then selected, based on natural circumferential compliancies. A material such as silicone rubber formed of an elastomer and a filler is used to form the aorta, the durometer of the material being varied by varying the relative amount of the components, to provide the selected amount of circumferential compliance in a simulated aorta having the selected dimensions. The aorta is then formed curing the material in the mold for about 24 hours. Groups of simulated aortas so produced, sometimes having different sizes and/or compliancies are also disclosed. A method of testing non-stented valves using the aortas is included.

  • Patent number: 6325776
    Abstract: The apparatus for diverting blood from the retro hepatic inferior vena cava (IVC) and internally shunting renal and infra renal IVC blood into the right atrium during surgery on the liver, its vessels, or the retro hepatic IVC is described. It is symmetrical on its mid horizontal axis permitting similar utility whether venous access was above or below the liver. It is a hollow plastic tube with two sidewall openings, one at each end with four intervening completely encircling balloons. It is continuous with a proximal component which serves to remotely manipulate, infuse fluids and inflate the balloons in the distal component. Once introduced into the venous system by right atriotomy or infrarenally by venotomy, the distal component would be advanced and seated in the right atrium and supra renal IVC.

  • Patent number: 6305378
    Abstract: This invention is a method for treating a patient diagnosed with atrial arrhythmia by forming a circumferential conduction block along a circumferential path of tissue in a pulmonary vein wall that circumscribes the pulmonary vein lumen and transects the electrical conductivity of the pulmonary vein such that conduction is blocked along the longitudinal axis of the vein wall and into the left atrial wall. The method is performed to treat a patient with a focal arrythmogenic origin along the pulmonary vein wall by either ablating the focal origin or by isolating the focal origin from the atrial wall with the circumferential conduction block. The circumferential conduction block is also formed in a pulmonary vein in order to bridge the adjacent ends of two linear lesions, wherein each linear lesion is formed to extend between the pulmonary vein and another adjacent pulmonary vein in a less-invasive “maze”-type procedure.

  • Patent number: 6302917
    Abstract: An esophageal prosthesis (10) for preventing reflux of gastric fluids through the esophagus. The esophageal prosthesis process includes a tubular frame (11) with a sleeve (13) disposed around and longitudinally along the tubular frame as well as extending from the distal end (14) of the frame. The lower portion (28) of the sleeve has a readily collapsible lumen (15) that forms a one-way valve for preventing the reflux of gastric fluids in an antegrade manner through the esophagus. Fluids however readily flow through the sleeve in a antegrade direction. In response to a pressure build up in the stomach of a patient wanting to belch or vomit, the lower portion of the sleeve inverts through the passage (12) of the tubular frame, thereby relieving the pressure build up or voiding the patient's stomach.
