INTRALUMINAL MEDICAL DEVICE
First Claim
Patent Images
1. An intraluminal medical device, the intraluminal device comprising:
- a self-expanding frame having a plurality of side elements interconnected by a plurality of oppositely facing bends;
the frame configured to move between a collapsed state in which the bends are compressed into near proximity with the side elements for delivery and retrieval and an expanded state in which the frame expands allowing the side elements to engage the body vessel; and
a pair of guide bars located on opposites ends of the frame;
the guide bars configured to couple with the oppositely facing bends such that the bars enable the frame to be retracted for delivery or retrieval from either end.

Abstract
A multi-sided intraluminal medical device having a self-expanding frame and a pair of guide bars located on opposite ends of the frame and adapted to enable the frame to be retracted for delivery or retrieval from either end is provided. The intraluminal device may further include a partial or full covering that is circumferentially attached to the frame. Such a medical device may be used as a stent to maintain an open lumen in a vessel (e.g., a vein, artery, or duct), as a valve, or as an occlusion device.

19. A method for delivering an intraluminal device to a targeted location in a body vessel for use as a stent, an occlusion device, or a valve;
- the method comprising the steps of;
introducing a delivery catheter having a proximal and distal end into the body vessel;
the distal end being located proximate to a targeted location in the body vessel;providing an intraluminal device;
the intraluminal device comprising;a self-expanding frame having a plurality of side elements interconnected by a plurality of oppositely facing bends;
the frame configured to move between a collapsed state in which the bends are compressed into near proximity with the side elements for delivery and retrieval and an expanded state in which the frame expands allowing the side elements to engage the blood vessel; andfirst and second guide bars located on opposites ends of the frame;
the first and second guide bars configured to couple with the oppositely facing bends;inserting the intraluminal device in the collapsed state into the proximal end of the delivery catheter; inserting an end of a pushing mechanism into the proximal end of the delivery catheter;
the end of the pushing mechanism adapted to make contact with one of the first or second guide bars;
the pushing mechanism adapted to move the intraluminal device through the delivery catheter;delivering the intraluminal device to the targeted location in the body vessel; and allowing the intraluminal device to move to the expanded state for engagement with the body vessel. - View Dependent Claims (20, 21)
