Patent ID: 8852229

Claim:
A locator and closure device comprising an elongate member, said elongate member having a lumen, a distal opening and a proximal opening which are connected by the lumen and a distal portion with a substantially uniform outer diameter wherein said distal opening is located within said distal portion, said elongate member being adapted to be advanced through an introducer member to extend into a blood vessel of a patient such that said distal opening is located in the lumen of the blood vessel, and said device being provided with a bioabsorbable occlusion member releasably attached by an attachment formed by contact between said occlusion member and said elongate member at a specific position of said elongate member, in contact with said lumen of said elongate member and located distally of said distal opening, said occlusion member comprising an unrestrained maximal outer diameter configured to correspond to a diameter of a tissue passageway opening into said blood vessel lumen, said occlusion member configured to substantially block blood flow out of said blood vessel when released into the tissue passageway opening, wherein when said distal opening is located in the lumen of the blood vessel, blood can enter said distal opening without passing through said occlusion member, flow through said lumen, exit through said proximal opening and be visible outside of the patient's body.
