  • Publication number: 20220160346
    Abstract: Disclosed is a system (100) for inserting an adapter. The system can include a docking station (104) and an adapter inserter (102). The docking station can include a handle block (108), a push assembly, and a linkage (320) connecting knob push handle (120) to an engagement tube pull block (324). The engagement tube pull block (324) can extend from the linkage through a portion of the handle bock. The adapter inserter (102) can include a handle body (112), an engagement assembly (116), and a clamp (412). The handle body can be sized to fit in a first recess (110) defined by the handle block body. The engagement assembly (116) can extend from a second end of the handle body (112) and can be configured to engage the adapter (132) at a tip of the engagement assembly. The clamp (412) can be located within and proximate a second end of the handle body so as to engage a portion of the engagement assembly.

  • Patent number: 10512531
    Abstract: A filter delivery device for implanting a vessel filter within a blood vessel of a patient's body. The filter delivery device includes a mechanism for preventing hooks and/or legs on a vessel filter from entangling with each other while the vessel filter is loaded within the delivery device. In one variation, the filter delivery device includes a delivery catheter with grooves at the distal end lumen opening. When a vessel filter with radially expanding legs is compressed and inserted into the distal end of the delivery catheter, the hooks on the distal end of the legs are received and separated by the corresponding grooves on the delivery catheter. In another variation, a pusher rod, with a receptacle for receiving the hooks, is positioned within a delivery catheter to prevent the entanglement of the hooks and/or legs of a filter loaded within the delivery catheter.

  • Publication number: 20180098838
    Abstract: A positioning and installation tool for a fixation implant is inserted through a single, simple drill hole and positioned in place. The device controls the degree to which the implant is deployed and prevents accidental disengagement of the device from the implant before deployment has completed. The device also guides the components of the implant involved in active tendon compression at the aperture of the bone tunnel. The implant is deployed simply by rotating a knob, thereby creating an anchor point of high stiffness and fixation strength. When deployment has completed, the inserter is disengaged from the affixed implant by simply pulling a release mechanism.

  • Patent number: 8465545
    Abstract: A material fixation system is particularly adapted to improve the tendon-to-bone fixation of hamstring autografts, as well as other soft tissue ACL reconstruction techniques. The system is easy to use, requires no additional accessories, uses only a single drill hole, and can be implanted by one person. Additionally, it replicates the native ACL by compressing the tendons against the aperture of the tibial tunnel, which leads to a shorter graft and increased graft stiffness. It is adapted to accommodate single or double tendon bundle autografts or allografts. It also provides pull out strength measured to be greater than 1000 N.

  • Patent number: 8267954
    Abstract: An implantable vessel filter having an integrated sensing capability for monitoring the condition of the vessel filter. In one variation, the vessel filter comprises a plurality of legs that would themselves perform as a sensor device for detecting distention, which would indicate the presence of a clot or thrombus therein. A passive electrical circuit may be implemented on the vessel filter to receive electromagnetic energy and transmit signals indicative of the condition of the implanted vessel filter. In another variation, a miniaturized sensor is adapted for measuring the strain and/or other physical parameters of the filter legs.
