  • Publication number: 20240024351
    Abstract: A topical composition that destroys an external hyperplastic tissue, while preserving a basic architecture of the external hyperplastic tissue rather than dissolution of hydrolysis of protein peptide bonds of the external hyperplastic tissue, thereby providing a timely regeneration of healthy skin tissue after the external hyperplastic tissue has been treated with the topical composition, and thereby contributing to less damage to surrounding healthy skin tissue, as a result of, destructive potential of the topical composition being effectively neutralized and penetration of the topical composition into the surrounding healthy tissue being effectively blocked. The topical composition includes a caustic portion and a detoxifying and cleansing portion. The caustic portion has a caustic effect on the external hyperplastic tissue.

  • Patent number: 9474887
    Abstract: Features of guides and surgical implements, which may be utilized together in various assemblies, are disclosed. Surgical implements or other devices within the scope of this disclosure may include a circumferentially grooved knob. The knob may be configured to receive a portion of a guide. Further, a clip may be configured to releasably secure the guide to the surgical implement. The clip may be coupled to the knob, for example, by a strap rotatably coupled to the knob. The knob may also define a stop-ledge configured as an abutment for the guide. The knob may also define a central passageway, which may also be surrounded by a hollow hub, for receiving an additional surgical implement or device.

  • Patent number: 7013928
    Abstract: A peritoneal dialysis catheter having an inflow conduit and an outflow conduit. Each conduits are linearly mated and contoured to cooperatively define a substantially circular cross sectional profile along a medial, trans-abdominal segment, but separating perhaps in radial fashion on either end of the medial, trans-abdominal segment, on a distal end to join fluted fluid transport branches and on proximal ends to join fittings for fluid delivery and collection external of the patient.

  • Patent number: 6589212
    Abstract: The present invention comprises a surgical implement guide sized for insertion into and compatible with tissues. The invention includes a hollow shaft formed of a flexible material with memory to return to a predetermined configuration, where the shaft defines a central passageway of variable inside diameter and is adapted to receive a catheter or other surgical tool or instrument. The central passageway terminates in an access opening and allows for insertion and removal of the catheter or tool An elongated tab member having at least one surface or portion thereof which is textured extends from the shaft, and positioned adjacent the access opening, acting as a handle to assist the user in removing the catheter. A tip is included opposite the tab to assist in the insertion of the guide, and thus the catheter or tool.

  • Patent number: 5676159
    Abstract: A flexible polyurethane cover with a closed end that is contact clear for establishing sterility while using an ultrasound probe. The cover has gel prepositioned inside the contact clear polyurethane closed end. A drape can be attached to the contact clear cover. A method of making such a cover including folding a contact clear polyurethane sheet over itself and securing the side edges to form a compartment with a closed end, inverting the cover as necessary to position the seams inside the cover, applying a gel into the closed end portion of the cover, and sterilizing the cover without affecting the gel by applying a dry heat in a slow persistent manner after the gel is already in the cover.
