  • Patent number: 4976718
    Abstract: A forceps for removing a parasite such as a tick from a human or animal host where the parasite has attached itself to the host at its head and the parasite contains fluids which can be expelled into the host upon the application of an external squeezing force, particularly a squeezing force applied to the body of the parasite. The forceps includes first and second arms each having a distal end and a proximal end and secured so that they are movable in opposition to one another between an open position and a closed position. A gripping section for engaging the parasite is mounted on the distal end of the forceps. The gripping section includes first and second sets of interdigitating teeth mounted on each of the opposed arms that are sized to closely surround the body of the parasite without crushing or squeezing any part of the parasite's body when the arms are in the closed position.

  • Patent number: 4888015
    Abstract: A method of replacing a human or animal lens is disclosed, along with a tool for use in such procedure and a flexible lens for use as an implant or transplant. The procedure includes the use of a horizontal capsulotomy incision to allow for the removal of the lens from the lens capsule without destruction or removal of any portion of the capsule. No sutures or other unnatural materials are required. A special tool for use in this procedure is disclosed which includes saucer-shaped gripping members which can grip and loosen the lens from the lens capsule and keep the capsule open during the transplant. The implanted lens, which may be of a soft material having a variable focus, is formed from an inert, non-toxic material. When a natural lens or a flexible artificial lens is utilized in the procedure, the natural constriction and relaxation of the ciliary muscles allows for the variation of the focus of the lens in a manner which closely approximates that of the original natural lens.
