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.

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.

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.

Apparatuses and methods for coating and/or loading a medical device with a therapeutic agent prior to or during the placement of the medical device within the patient's body. In one variation, the medical device is coated and/or loaded with a therapeutic agent while the device is positioned in a delivery apparatus. In another variation, the delivery apparatus comprises a reservoir for retaining a therapeutic agent. The user may release the therapeutic agent from the reservoir prior to or during the placement of the device to coat and/or load the device with the therapeutic agent.

A stent compression method for particular use in pre-surgical securing and conforming of a vascular stent upon an angioplasty balloon. One variation of the stent compression method comprises inflating an agioplasty balloon inside a vascular stent in order to secure the vascular stent upon the balloon; applying uniform compression pressure around the balloon/stent unit; and adjusting the internal balloon pressure and the compression pressure so that the balloon/stent unit is compressed. A pressure chamber with an elastic cylindrical membrane mounted inside the chamber may be used to provide the compression pressure. The inflated balloon provides the balancing pressure from inside the stent. The maintenance of internal balloon pressure during the stent compression process may provide uniform distribution of pressure along the stent and even radial compression rate around the circumferential surface of the stent.
