Insertion assembly and method of inserting a vessel plug into the body of a patient
DC CAFCFirst Claim
1. A closure device for sealing an incision formed in the body of a patient wherein the incision extends from the skin of the patient through the lumen of a blood vessel and into a blood vessel of the patient, said closure device including a plug means comprising:
- an elongate and generally cylindrical vessel plug having distal and proximal ends, and said vessel plug has a length sufficient to be received in the incision such that said distal end is positioned at a first predetermined position in the incision proximally of the lumen of the blood vessel of the patient, and said proximal end is positioned adjacent to the outer surface skin of the patient to obstruct the flow of blood from the blood vessel into the incision; and
wherein said distal end of said vessel plug is oriented at an angle of approximately 25 to 45 degrees with respect to the lengthwise dimension of said vessel plug.

Abstract
A device and method of closing an incision or puncture in a patient by inserting a vessel plug into the incision or puncture until the distal end of the vessel plug is adjacent to the outer lumen of the blood vessel or target organ so that the vessel plug does not obstruct the flow of fluid through the blood vessel or target organ. The precise positioning of the vessel plug in the incision or puncture is accomplished through the use of a balloon catheter or a cylindrical insertion assembly having a proximal plunger member associated therewith.

6. An insertion assembly for sealing an incision formed in the body of a patient wherein the incision extends generally from the skin of the patient through the lumen of the blood vessel and into a blood vessel of the patient, said insertion assembly comprising in combination:
-
a vessel plug having distal and proximal ends and being formed of a material which is absorbable in the body of the patient, said vessel plug being dimensioned to be inserted into the incision of the patient such that sad distal end of said vessel plug is positioned along the outer surface of the blood vessel of the patient and said proximal end is positioned generally adjacent to the outer surface of the skin of the patient; a removable insertion member having proximal and distal ends wherein said distal end is dimensioned to facilitate the identification of the location of the lumen of the blood vessel adjacent to the incision and assist in the placement of said distal end of said vessel plug along the outer surface of the blood vessel; and wherein said vessel plug is an elongate and generally cylindrical member, and said distal end of said vessel plug is oriented at an angle of approximately 25 to 45 degrees with respect to the lengthwise dimension of said vessel plug. - View Dependent Claims (7, 8)

9. A method of sealing an incision formed in the body of a patient wherein the incision extends generally from the skin of the patient;
- through the lumen of a blood vessel and into the blood vessel of a patient, the method including the steps of;
forming a vessel plug of a material which is absorbable in the body of the patient and wherein the vessel plug is formed to include distal and proximal ends therein and is dimensioned to be received in the incision; and positioning the vessel plug in the incision such that the distal end of the vessel plug is located proximally of the blood vessel to seal the incision from the flow of blood passing through the blood vessel. - View Dependent Claims (10, 11, 12, 13, 14, 15)
