Patent number: 7331938Abstract: The present invention provides liquid injector 100 wherein syringe 210 sucks a liquid from liquid tank 200 in a suck state in which connection switch mechanism 105 connects syringe tube 103 to tank tube 102, and syringe 210 injects the liquid into a patient in an injection state in which connection switch mechanism 105 connects syringe tube 103 to patient tube 101. Since connection switch mechanism 105 blocks patient tube 101 in the suck state, the liquid does not flow back into syringe 210 from the patient. Since tank tube 102 is blocked in the injection state, the liquid does not flow back into liquid tank 200 from syringe 210. Therefore, it is possible to provide liquid injector 100 capable of preventing a backflow of the liquid from the patient to syringe 210 or liquid tank 200 in the structure in which syringe 210 sucks and injects the liquid from liquid tank 200 into the patient.Type: GrantFiled: August 6, 2003Date of Patent: February 19, 2008Assignee: Nemoto Kyorindo Co.

The intravascular device has an outer delivery member with a distal section which has an elongated opening and a support element coextending with the opening. An EP device having a plurality of electrodes on its distal section is slidably disposed within the inner lumen of the delivery member but it is secured by its distal end within the distal extremity of the delivery member at least while in operation. In this manner an axial force in the proximal direction on the proximal extremity of the EP device, which extends out of the patient during the procedure, will cause the distal shaft section of the EP device to arch outwardly out of and away from the distal section of the delivery shaft along an inner side of the curved distal section and engage the surface of the patient's heart chamber.Type: GrantFiled: November 3, 2004Date of Patent: February 19, 2008Inventor: Alan K Schaer

Patent number: 7331961Abstract: A bone plating system is provided that permits maintenance of a compression force while also accommodating bony subsidence, among other features. Methods of implantation are also provided that improve alignment and placement during implantation and avoid maneuvers that weaken the vertebral bodies. A modular distraction screw is placed during the initial stages of surgery when all relevant landmarks are still intact. After completion of the surgical bone work, a proximal end of the distraction screw is detached, leaving a protruding distal segment implanted in the centerline of the vertebral bodies above and below the newly fused disc space. A bone plate is guided into proper position relative to the upper and lower vertebra by attaching the bone plate to the protruding distal segments. The distal segments of the distraction screws are tightened onto the plate and the plate is held stationary while bone screws are placed.Type: GrantFiled: January 10, 2004Date of Patent: February 19, 2008Inventor: M. Samy Abdou

Patent number: 7331962Abstract: A fixture having an anchoring portion and an application portion intended for connection to a prosthesis. The application portion has an outer end and an end connected to the anchoring portion. The application portion includes a flared part whose outer dimensions widen from the end of that part connected to the anchoring portion in a direction toward the outer end of the application portion. This flared part is elastically resilient transversely to the longitudinal direction of the fixture.Type: GrantFiled: December 18, 2003Date of Patent: February 19, 2008Assignee: PIOS Biotech ABInventor: Per-Ingvar Brånemark

Patent number: 7331963Abstract: A drill head for preparing the bone of two opposing vertebral bodies to accept the concaval-convex shape of an endoprosthesis includes a form cutter having at least one predetermined milling surface, drive means, and a housing. The form cutter has a profile allowing the drill head to fit in the narrow space between two opposing vertebral bodies in the cervical spine of a patient. The drill head is used in a method for preparing the disc space between adjacent vertebrae of a human spine to receive an endoprosthesis therebetween, the method being performed by contacting at least one vertebral body with a movable form cutter.Type: GrantFiled: October 6, 1997Date of Patent: February 19, 2008Assignee: Warsaw Orthopedic, Inc.Inventors: Vincent Bryan, Alex Kunzler

Patent number: 7331964Abstract: The present invention provides for a laser therapy device for animals and methods of manufacturing and using the same. In one embodiment, the animal therapy device is comprised of (i) a hairbrush body housing a plurality of wide-pattern laser LEDs configured to cooperate to project a precision laser light pattern at a focal plane proximate an area to be irradiated; and (ii) bristles extending from the hairbrush body and terminating substantially at the focal plane. Laser light is used to treat different portions of the animal body.Type: GrantFiled: November 17, 2005Date of Patent: February 19, 2008Assignee: Sunetics International, L.P.Inventors: Charles E. Maricle, John F. Carullo, Jr.

Patent number: 7331966Abstract: Disclosed herein is a device (such as guidewire inserter) for easily and certainly inserting a medical long item having a curved tip into a tube such as catheter and sheath. The guidewire inserter is a tubular member having therein a bore for passage of a guidewire. The tubular member has a slit cutting across the wall thereof over the total length thereof. The tubular member has at the proximal end thereof an aperture, which results from the slit expanding toward the proximal end. The tubular member has at the proximal end of the aperture an open part and a connecting part adjacent thereto for the holder tube. There are a pair of wing-like protruded pieces projecting in the mutually opposite directions at both sides of the open part. The distal end of the tubular member has on its outer surface a pair of protruded rims, which project in the mutually opposite directions with respect to the central axis of the tubular member.Type: GrantFiled: March 1, 2005Date of Patent: February 19, 2008Assignee: Terumo Kabushiki KaishaInventors: Katsuaki Soma, Toshiaki Takagi, Hiroshi Yagi, Takayuki Mori, Katsuhiro Shirakawa, Hiraku Murayama

Patent number: 7331967Abstract: A surgical apparatus includes a slider mechanism, a surgical instrument coupled to the slider mechanism, and a single cable bundle that couples the slider mechanism and instrument to a driver. The single cable bundle includes a first cable that operates the slider mechanism and thus the instrument with one degree-of-freedom of movement, and a second cable that operates the instrument itself with another degree-of-freedom of movement. The cable bundle is attached to the slider mechanism at a location that is stationary.Type: GrantFiled: November 21, 2002Date of Patent: February 19, 2008Assignee: Hansen Medical, Inc.Inventors: Woojin Lee, Michael J. Mazzuca, Michael C. Gorhan

Patent number: 7331968Abstract: A flexible endoscopic clip applier includes a flexible coil with a manual actuator coupled to one end and a jaw assembly coupled to the other end. A store of clips is arranged adjacent to the jaw assembly and a clip pusher is arranged adjacent to the store of clips. The actuator includes a lever for opening and closing the jaws, a knob for rotating the jaw assembly, and a crank for dispensing clips. The knob and the lever are coupled to a single control member which extends through the coil to a joiner where it is joined to a pair of pull wires coupled to the jaws. The crank is coupled to a second control member which is threaded along a distal portion. The threaded portion engages a threaded member near the pusher and is coupled to the pusher such that rotation of the threaded control member by the crank causes the pusher to be moved distally.Type: GrantFiled: June 14, 2004Date of Patent: February 19, 2008Assignee: Ethicon Endo-Surgery, Inc.Inventors: Scott Arp, Kevin W. Smith
