  • Patent number: 6685706
    Abstract: Disclosed is a bone fixation device of the type useful for connecting soft tissue or tendon to bone or for connecting two or more bones or bone fragments together. The device comprises an elongate body having a distal anchor thereon. An axially moveable proximal anchor is carried by the proximal end of the fixation device, to accommodate different bone dimensions and permit appropriate tensioning of the fixation device.

  • Publication number: 20040010257
    Abstract: Disclosed is a bone fixation device of the type useful for connecting soft tissue or tendon to bone or for connecting two or more bones or bone fragments together. The device comprises an elongate body having a distal anchor thereon. A proximal anchor is axially movably disposed with respect to the distal anchor, to accommodate different bone dimensions and permit appropriate tensioning of the fixation device. In one embodiment, the fixation device is optimized for construction from a biocompatible metal such as titanium, and the proximal anchor is removable to permit removal of the fixation device.

  • Publication number: 20030030542
    Abstract: Disclosed is a personalized security system for use with a PDA or other portable electronic device. An interrogator signal is transmitted from the portable electronic device, triggering a responsive transmission of a password from an electronic key carried by the wearer. Certain selected functions or all functions of the electronic device are therefore only enabled if the electronic device is within a predetermined operating proximity of the electronic key. Also disclosed is a personal preference monitoring system, for allowing personal preferences to be automatically implemented in response to a user passing within a predetermined distance of an interrogation signal transmitter.

  • Patent number: 6461347
    Abstract: Disclosed is a low profile catheter shaft configuration for incorporation into any of a variety of catheters. The shaft comprises first and second side-by-side lumens with a movable wall extending axially therebetween. The first lumen may occupy more than half of the inside diameter of the shaft such as during advancement along a guidewire, and the second lumen may occupy more than half of the inside diameter such as following withdrawal of the guidewire and during inflation of a balloon. Methods are also disclosed.

  • Publication number: 20020143334
    Abstract: Disclosed is a fracture fixation device, for reducing and compressing fractures in a bone. The fixation device includes an elongate body comprising a first portion and a second portion that are detachably coupled to each other. The first portion defines a helical cancellous bone anchor and the second portion defines a distal end. An axially moveable proximal anchor is carried by the proximal end of the fixation device and is rotationally locked to the first portion. The device is rotated into position across the femoral neck and into the femoral head, and the proximal anchor is distally advanced to lock the device into place. The second portion is then detached from the first portion.

  • Patent number: 6048299
    Abstract: Disclosed is a delivery catheter adapted for delivery of a dose of radiation to a vessel wall. A radiation source is enlargeable from a first, reduced cross-sectional profile to a second, enlarged cross-sectional profile by unwinding around a central core. Following delivery of a radiation dose to the vessel wall, the source is reduced in profile by wrapping around the core and removed from the treatment site.

  • Patent number: 5879324
    Abstract: Disclosed is a low profile catheter shaft configuration for incorporation into any of a variety of catheters. The shaft comprises an inner collapsible tube coaxially disposed within an outer tube. The outer tube may be collapsible or relatively noncollapsible. The effect of the structure is to provide first and second side-by-side lumens with a movable wall extending axially therebetween. The first lumen may occupy more than half of the inside diameter of the shaft such as during advancement along a guidewire, and the second lumen may occupy more than half of the inside diameter such as following withdrawal of the guidewire and during inflation of a balloon. Methods are also disclosed.
