  • Patent number: 6533799
    Abstract: A design and method of manufacture are disclosed for a cavity measurement device used during surgical procedures. The cavity measurement device includes an inflation tube assembly comprising an elongated tube having a distal end and a proximal end and a balloon mounted at the distal end of the elongated tube. The elongated tube and the balloon comprise dissimilar materials and include an adhesive free seal between the elongated tube and the balloon. The inflatable balloon is inserted into a cavity and inflated with a volume of fluid, whereby the balloon volume represents the cavity volume. The mechanical attachment of the balloon onto the tube is substantially leakproof and has an attachment strength greater than the balloon material tensile strength. The mechanical attachment of the present invention substantially eliminates the potential for bond separation and preparatory operations typically associated with adhesive bonds.

  • Patent number: 6533719
    Abstract: A pump assembly for a penile implant is provided having a mechanism which prevents spontaneous inflation of the cylinders implanted within the user. The preventative mechanism uses overpressure generated by the reservoir during unintentional compression to effectively seal the pump assembly from unintended fluid flow. The prevention mechanism itself creates all necessary forces to prevent the undesired fluid flow to the cylinders. This is accomplished by incorporating appropriate mechanisms within the pump itself.

  • Patent number: 6461355
    Abstract: A design and method of manufacture is disclosed for an insulated electrode used during surgical procedures. The electrode includes a durable electrical insulation element that can withstand the range of temperatures generated during an electrosurgical procedure. Such insulation characteristics include resistance to meltback and manufacturability to ensure the device is biocompatible and non-toxic so as to prevent adverse reactions in both patients and users of the device. The insulated electrode further includes properties that reduce the incidence of scope damage caused by the intensity of heat generated during the cutting and coagulation cycles.

  • Patent number: 6460262
    Abstract: An apparatus and method for measuring the size of a body passage is provided. The apparatus comprises a flexible strip having first and second ends. At least one aperture is disposed on the strip between the first and second ends. An indicia of body passage circumference is disposed on the strip in association with the at least one aperture. The body passage may be measured by inserting the strip into a dissected tunnel around the body passage, manipulating the strip such that the strip substantially surrounds the body passage, and observing the indicia on the strip to generally determine the circumference of the body passage.

  • Patent number: 6461291
    Abstract: A device for treating leakage from an external orifice in the body of a patent which comprises a first member having a body-contacting first surface and an opposing second surface about an aperture, which first surface is attachable to the patient with said aperture positioned over said orifice, and a second member integral with said second surface, which second member comprises a valve mounted over said aperture, which valve has a closed position which prevents leakage of fluid through the device and an open position which allows fluid to flow through said aperture when desired, the closed and open positions being achievable without removing the device from the body of the patient.

  • Patent number: 6391142
    Abstract: A substrate is permanently bonded to a thermoplastic member by applying a sufficient degree of heat and pressure. Thermoplastic is notoriously non-receptive to even the most aggressive adhesives. As such, it has been extremely difficult to attach non-plastic components to thermoplastic products. To avoid this problem, the thermoplastic product is heated, on one side, to a temperature just below its melting point. A substrate, made of a material such as polyethylene, is placed against the non-heated side of the thermoplastic. As heat passes through the thermoplastic, it heats and eventually melts a portion of the substrate. Ideally pressure is applied to force the melted material against the substrate. The materials are then allowed to cool and harden, thus forming a permanent bond between them. Additional materials may be coupled to the substrate, as desired.
