  • Publication number: 20020049440
    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: 5553379
    Abstract: A malleable penile prosthesis adapted to be implanted in a corpus cavemosum of a penis comprising an elongated core which is bendable about its longitudinal axis with the capability of holding the configuration to which it is bent and is substantially rigid when in the unbent straight configuration, a sleeve of braided biocompatible material, having an inner surface and an outer surface, enveloping the core with the inner surface of the sleeve in contact with the core and the sleeve and core being accommodated within an outer tube of elastomeric material, which tube has a substantially rounded smooth outer surface and an inner surface having a profile formed of alternate grooves and ribs in a substantially helical arrangement. A method of forming a malleable prosthesis is also disclosed.
