  • Patent number: 7288096
    Abstract: Surgical procedure and surgical instruments include an electrode structure for insertion through tissue superiorly of a subxiphoid incision to a position posterior of an aspect of the sternum and anterior of the pericardium. The electrode structure may be expanded, for example, including an inflatable member to position a number of electrodes of the electrode structure in contact with the pericardium. Alternatively, an electrode structure on an insertion cannula may be retained in contact with the pericardium by the cannula positioned within the dissected tissue. Electrical conductors from the contacting electrodes are routed through the tract of dissected tissue toward the subxiphoid incision for attachment to a generator that is implanted in a subcutaneous pocket near the subxiphoid incision.

  • Patent number: 6953465
    Abstract: This is directed to containers and methods for holding and delivering vaso-occluding materials such as hydrogel particles and filaments. The vaso-occlusive materials may be held in the container in a hydrated or unhydrated state. The container includes a fluid ingress port and a fluid egress port that are respectively fluidly connectable with a fluid source and a delivery catheter. The container further includes at least one chamber or passageway extending therebetween. The passageway may be straight, curved, spiral, helical, narrow or otherwise shaped. The chamber may also have sections of varying cross section such as a ramped section. The shapes of the passageways of the container help organize ejection of the vaso-occluding materials minimizing contamination and clumping. Methods for holding and introducing the materials are also provided.

  • Patent number: 6884255
    Abstract: A pneumatic system consists of an inflatable/deflatable article, for example, a compression garment (21) connected to a pump (20) by connectors (12 and 11), respectively. The connector (12) attached to the garment (21) carries an RFID transponder (30) and a corresponding radio circuit (31) is located within the pump (20). In use, the transponder (30) transmits and receives information to and from the pump radio circuit (31). The information exchanged is used by the pump control system to activate the pump and to operate the pump to provide the particular operating parameters for that garment, for example, pressure, inflation/deflation cycle, duration of treatment, etc.

  • Patent number: 6863073
    Abstract: Featured is a device for puncturing tissue of a body, such as the lamina cribosa and methods for treating a CVRO with such a puncturing device. The puncturing device includes a puncture member being generally configured and arranged to locally disrupt tissue proximal an area of the puncture site, to minimize the potential for damage to body parts or tissue immediately adjacent to this area of the puncture site and to facilitate perforation of the tissue at the puncture site. When the lamina cribosa is being punctured, the puncture member is more particularly configured and arranged to locally disrupt connective tissue of the lamina cribosa proximal to and surrounding the central retinal vein while minimizing the potential for structural damage to the central retinal vein. In an exemplary embodiment, the lamina cribosa is repeatedly punctured to strip/locally disrupt connective tissue surrounding the central retinal vein.

  • Patent number: 6852119
    Abstract: The invention of the present disposable adjustable lancet involves an assembly which has a body and a cap. A lancet holder fits in the body and has a base portion having a pair of upstanding retainer-disabling tines, one of the tines is longer than the other to block the reinsertion of the lancet. A selector tip assists in engaging a clicker position in the selector tip. The method involves selecting positions by means of a female and a male position clicker which provide an audible signal. The position of the lancet can be determined in three manners: visually observing the degree of rotation, audibly denoting the click, and physically rotating the member which, in turn, results in a reaction on the finger while the adjustment is being made.

  • Patent number: 6827086
    Abstract: The invention provides for treating deleterious body tissue located within healthy body tissue by isolating the deleterious tissue from blood, air, and fluid communication. The device includes two structures, each having a corresponding circumferential surface arranged to circumscribe the deleterious body tissue. When the first and second circumferential surfaces are brought together in an aligned relationship with the deleterious body tissue between the structures, the two circumferential surfaces co-act to isolate the deleterious body tissue from communication with the healthy body tissue. The deleterious tissue is resected according to the invention by allowing it to become ischemic and necrotic, or by excision.

  • Patent number: 5069203
    Abstract: A soft hand or hand and wrist splint for controlling and reducing hand and/or hand and wrist flexion contractures. The splint has a soft flexible body member such as polyurethane foam having a density of 1.1 to 2.0 pounds per cubic foot and an indentation load deflection on the order of 33 for a medium firm foam. The body member is sized so that its length extends from the fingertips to a region intermediate the thumb and the wrist or, if desired, to a region intermediate the wrist and the elbow depending upon whether just metacarpal flexion contratures are to be controlled or metacarpal and wrist flexion contractures are to be controlled, respectively. The body member is preferably covered with a soft stretch material such as a stretch terry cloth. A plurality of strap means are positionable over the body member and, if desired, may be secured or coupled to the terry cloth covering.

  • Patent number: 5058576
    Abstract: An adjustable wrist and hand splint employs four rigid aluminum stays for providing support for the forearm, fourth and fifth fingers and the outer portion of the hand. The aluminum stays are bendable for accommodating particular needs of the user. The splint also employs a sleeve that encompasses and provides further support for the forearm, fourth and fifth fingers and outer portion of the hand. The sleeve also provides padding between the stays and the forearm, hand and fingers. In addition, the splint includes pockets that are secured to the sleeve. The aluminum stays are housed within the pockets. Further, the splint may be readily put on or removed using a set of adjustable straps. The straps normally include "Velcro" type material that engage the mating "Velcro" type material on the surface of the sleeve. The fastening straps also help to further immobilize the wrist, fourth and fifth fingers and outer portion of the hand.
