Abstract

This invention relates to apparatus and methods for use in sealing a vascular puncture site and to apparatus and methods for properly locating and deploying a sealing device. The locating apparatus comprises a lumen which extends from an opening in the distal region of the apparatus but located proximally of the sealing device, which lumen extends to another opening in the proximal region of the device. When the distal opening is in communication with blood in a blood vessel, blood flow through the lumen and out of the proximal opening signifies such location to the user. When the sealing device is withdrawn such that the sealing device is deployed such that it blocks the blood flow into the distal port, the user will know the location of the sealing device. In a preferred embodiment, the sealing device is then withdrawn proximally a predetermined distance to assure that no part of the sealing device extends into the blood vessel lumen. The sealing device is then detached from the delivery device.

Claims

1. A locator device comprising

an elongate member, said elongate member having a distal opening and a

proximal opening which are connected by a lumen,

said elongate member being adapted to extend into a blood vessel of a patient such that said distal opening is located in the lumen of the blood vessel and such that blood flow through said proximal opening is visible outside of the patient'"'"'s body, and

said device being provided with an occlusion member located distally of said distal opening, said occlusion member being capable of substantially blocking blood flow out of said blood vessel when it is withdrawn from said blood vessel lumen.

2. The device of claim 1 wherein said occlusion member is releasably coupled to said elongate member.

3. The device of claim 2 wherein said occlusion member is expandable.

4. The device of claim 2 wherein said occlusion member is bioabsorbable.

5. The method of installing a closure device adjacent to, but outside of a puncture in a blood vessel wall comprising the steps of

introducing an elongate member through a tract extending from said puncture to the patient'"'"'s skin, said elongate member having a first opening in its distal region, a second opening in its proximal region and a lumen extending between said first opening and said second opening,

said elongate member being provided with an occlusion member located distally of said first opening,

advancing said elongate member until said first opening is located within the lumen of said blood vessel such that blood flows into said first opening and not out of said second opening, and

withdrawing said elongate member until the flow of blood into said first opening is substantially prevented.

6. The method of claim 5 wherein said occluding member is releasably coupled to said elongate member and said occluding member is released from said elongate member.

7. The method of claim 6 wherein said occluding member is released of substantially the same time that blood flow into said first opening is substantially prevented.
