  • Patent number: 6936210
    Abstract: A method of making a cannula includes providing a plurality of polymer reservoirs with each reservoir containing a polymer material and providing a nozzle mounted within each reservoir of the plurality of reservoirs. The method further includes one or more of preheating the mandrel, generating a polymer material wave from each nozzle, rotating the mandrel over the nozzles to form an initial coat on the mandrel, curing the initial coat, depositing a reinforcing material around a selected section of the mandrel and ensuring that the reinforcing material is held in place at the selected section of the mandrel. The method further includes rotating each section of the mandrel over a selected nozzle to form an additional coat, curing the additional coat, and removing the tubular structure from the mandrel.
    Type: Grant

  • Patent number: 6929766
    Abstract: A method of making a cannula utilizing dispense molding includes providing at least one dispense nozzle that dispenses a polymer material, providing a mandrel, moving at least one of the mandrel and at least one dispense nozzle relative to one another to produce an alternating pattern of polymer material along a longitudinal axis of the mandrel to form a tubular structure, and removing the tubular structure from the mandrel.

  • Patent number: 6231601
    Abstract: A method of surgery including bending a multi-purpose surgical implement handle that has proximal and distal ends. A gripping section is located toward the proximal end, and an attachment section is located toward the distal end. An adjusting section is interposed between the gripping section and the attachment section. The adjusting section may be bent by a human user at virtually any discrete location along the section. The adjusting section may include an increased-adjustability portion which is easier to bend than other portions of the adjusting section. The method includes attaching a surgical implement to the attaching section of the handle, and bending the adjusting section at least once prior to inserting the implement through a surgical opening to a surgical field. The method further may include bending the adjusting section more than once to form multiple bends therein.
