A removable vena cava filter configured for reduced trauma and enhanced visualization of anchoring hook placement relative to the vessel wall is disclosed. The filter includes a plurality of struts, each having an anchoring hook and a stop member proximate the anchoring hook. The stop members are configured to engage the vessel wall to prevent excessive penetration of the anchoring hooks into the vessel wall and to aid in the identification of anchoring hook placement relative to the vessel wall.

An occlusion device () includes at least one self-expanding frame () and graft material (). Occlusion occurs by constricting the graft material () at a substantially central point or at an end of the device. The constriction is sized such that a guide wire () is able to pass therethrough. A valve mechanism () includes a screen () made from a resilient material and which includes a closable opening (). The valve mechanism () allows a guide wire to pass through the occlusion device () while an effective physical barrier is maintained after removal of the guide wire ().

The filter includes a plurality of struts (-), each having an anchoring hook () and a stop member () proximate the anchoring hook. The stop members are configured to engage the vessel wall to prevent excessive penetration of the anchoring hooks into the vessel wall and to aid in the identification of anchoring hook placement relative to the vessel wall.

An introducer for use in the implantation and retrieval of a device in a patient includes a catheter () within which a stylet () is slidably carried, the stylet () being biased to a retracted position by a spring () and deployable by depression of an actuator (). A locking device () locks the stylet () relative to the catheter () such that the locking device () must be disengaged prior to operation of the actuator (). In the preferred embodiment, both the locking device () and the actuator () must be actuated by movement thereof in a direction substantially perpendicular to the direction of motion of the stylet (). In an alternative embodiment, it is the catheter () which moves relative to the stylet ().

Method and apparatus for introducing intraluminal prostheses

An assembly comprising: a protective sheath and a loading device for loading a self-expandable prosthesis into the sheath, the loading device having a conical distal section, which radially compresses the prosthesis and an annular lip that engages with the interior of the distal end of the sheath to guide the prosthesis into the sheath while protecting the sheath from damage.
