An occlusion device has a covering attached to a support frame that includes a disc-shaped member and a crossbar that extends across a central opening defined by the disc-shaped member. The occlusion device has a first, or deployed, configuration in which the crossbar defines a curve that extends from the disc-shaped member, and a second, or resting, configuration in which the disc-shaped member and the crossbar lie substantially in a single plane. Each of the disc-shaped member and the crossbar include a core wire that extends through a lumen of a coil multiple times.

Multi-stage occlusion devices

A multiple-sided medical device comprises a frame comprising wire or other resilient material and having a series of bends and interconnecting sides. The device has both a flat configuration and a second, folded configuration which a generally serpentine shape. The device is pushed from a delivery catheter into the lumen of a duct or vessel and may include one or more barbs for anchoring purposes. A full or partial covering of fabric or other flexible material such as DACRON, PTFE, or a collagen-based material such as small intestinal submucosa (SIS), may be sutured or attached to the frame to form an occlusion device, a stent graft, or an implantable, intraluminal valve such as for correcting incompetent veins in the lower legs and feet.

Implantable vascular device

A multiple-sided medical device comprises a frame comprising wire or other resilient material and having a series of bends and interconnecting sides. The device has both a flat configuration and a second, folded configuration which a generally serpentine shape. The device is pushed from a delivery catheter into the lumen of a duct or vessel and may include one or more barbs for anchoring purposes. A full or partial covering of fabric or other flexible material such as DACRON, PTFE, or a collagen-based material such as small intestinal submucosa (SIS), may be sutured or attached to the frame using heat or pressure welding crimping, adhesive, or other techniques to form an occlusion device, a stent graft, or an implantable, intraluminal valve such as for correcting incompetent veins in the lower legs and feet.

A multiple-sided valve for implantation within a body vessel comprising a frame comprising a bioabsorbable material is provided. The devices can be pushed from a delivery catheter into the lumen of a duct or vessel and may include one or more barbs for anchoring purposes. A full or partial covering of fabric or other flexible material, or a bioabsorbable material, including a collagen-based material such as small intestinal submucosa (SIS), may be attached to the frame to form an occlusion device, a graft, or an implantable, intraluminal valve such as for correcting incompetent veins in the lower legs and feet.

Implantable vascular device comprising a bioabsorbable frame

A stent graft () with a stent frame () having a plurality of stents () connected together with monofilament line (). A covering () of collagen having an extracellular matrix (ECM), such as small intestine submucosa (SIS), is disposed through the inside and over the outside of the stent frame. The covering () is affixed to the stent frame () such as by being sutured onto the stent frame at the ends of the stent frame and also at the connections of the stent bodies, such as at eyelets ().

Endovascular stent graft

A multiple-sided medical device comprises a closed frame of a single piece of wire or other resilient material and having a series of bends and interconnecting sides. The device has both a flat configuration and a second, folded configuration that comprises a self-expanding stent. The stent is pushed from a delivery catheter into the lumen of a duct or vessel. One or more barbs are attached to the frame of the device for anchoring or to connect additional frames. A covering of fabric or other flexible material such as DACRON, PTFE, or collagen, is sutured or attached to the frame to form an occlusion device, a stent graft, or an artificial valve such as for correcting incompetent veins in the lower legs and feet. A partial, triangular-shaped covering over the lumen of the device allows the valve to open with normal blood flow and close to retrograde flow.

Multiple-sided intraluminal medical device

An endovascular graft prosthesis for arrangement at an aneurysm positioned in the vicinity of a bifurcation in an arterial system having a main lumen and a first and a second branch lumen. The endovascular graft prosthesis includes a prosthetic device with at least one expandable tubular frame body for arrangement in the main lumen and a first and a second graft limb. The frame body is contractible into a first shape with a smaller diameter for introduction to a vascular site upstream of the aneurysm and is radially expandable into a second shape having a larger diameter and an inner lumen. The frame body is provided with a covering which extends across the inner lumen of the tubular frame body and has two apertures each of which has a diameter of less than half the larger diameter of the frame body. The first and second limbs have a cranial end for mounting at one of the apertures and a caudal end for arrangement in one of the branch lumens. The covering is a hindrance to blood flowing past the frame body except for blood flowing into the first and second graft limbs mounted at the two apertures.
