  • Publication number: 20030045774
    Abstract: An apparatus and method of use are disclosed to treat urological disorders. The biocompatible device includes a handle, needle, dilator and sling assembly configured to be minimally invasive and provide sufficient support to the target site. In addition, the configuration of the sling assembly also allows the sling to be adjusted during and/or after implantation. The device and treatment procedure are highly effective and produce little to no side effects or complications. Further, operative risks, pain, infections and post operative stays are reduced, thereby improving patient quality of life.

  • Publication number: 20030028076
    Abstract: This invention provides an artificial sphincter including a component coated on at least one contacting surface with a polymeric material, the polymeric coating adapted to expand and return to an original configuration and to prevent or inhibit wear or abrasion of the contacting surface. The polymeric material is parylene in some embodiments. The component adapted for inflation and deflation may be a cuff formed from silicon and adapted to surround a urethra or a rectum. Also provided by the present invention is a method of depositing a coating to a surface of an inflatable component by providing a vacuum chamber system having an inner chamber positioned within an outer chamber. At least one coating material is introduced into at least one of the inner and outer chambers to deposit a coating onto an exposed surface of the component. This invention also provides methods of masking portions of surfaces of an inflatable component to prevent a coating from being deposited on the masked portion.

  • Publication number: 20020183827
    Abstract: A stent delivery system and method for intraluminal delivery and deployment of a self-expanding prosthesis at a site within a body canal is provided. The delivery system comprises a housing removably attached to a delivery tool. The housing stores the self-expanding prosthesis in an expanded state. The delivery tool has a catheter assembly with a capture zone. The capture zone receives and contains the self-expanding prosthesis in a compressed state. A securing mechanism couples the catheter assembly to the self-expanding prosthesis, wherein the securing mechanism transfers the self-expanding prosthesis from the housing to the capture zone immediately prior to the delivery and deployment procedure.

  • 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.

  • Publication number: 20020099259
    Abstract: An apparatus and method of use are disclosed to treat urological disorders. The invention is a repositionable handle for an arcuate needle configured to be minimally invasive. The invention is for use with a sling assembly that allows a sling to be controllably implanted in a therapeutically effective position. The device and treatment procedure are highly effective and produce little to no side effects or complications. Further, operative risks, pain, infections and post operative stays are reduced.

  • Publication number: 20020091302
    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.

  • Publication number: 20020082619
    Abstract: Surgical apparatus and associated methods of use are provided for enhancing the functional life-span of medical implants and for facilitating their implantation, particularly for medical devices designed to support anatomical structures. The apparatus comprises a reinforcing fastener guide for fixedly mounting or interlocking onto the surface of a medical device such as a urethral sling or the like. Formed of surgical grade metals or plastics, the attached reinforcing fastener guide defines an easily identified location for the implanting surgeon to position one or more surgical fasteners, such as a suture, to the patient's body in order to permanently position the medical implant. This greatly simplifies and shortens the implantation protocol while substantially reducing undesirable mechanical stresses within the implant at these attachment points, thereby increasing the useful life of the implanted medical device.

  • Publication number: 20020072694
    Abstract: The present invention relates to a sling, methods of making and using a sling, and kits comprising a sling for treating urinary incontinence. The sling has multiple elongation properties that serve to improve the support of the urethra. The sling may comprise a coated material adapted for urethral suspension. The coated sling has properties that appear to enhance the sling elongation characteristics. The coated sling further includes properties that reduce its susceptibility to bacterial infections. The sling further includes properties to enhance the proper tensioning of the sling.
