Abstract
Abstract A vessel plug having a handle which include a proximal end and a distal end, a flange attached to the distal end of the handle, and a tip extending distally beyond the flange. In use, the flange and the tip are shaped to engage an opening of a blood vessel, provide occlusion to the opening of the vessel to block the blood flow, thereby achieving hemostasis. The plug may be sutureless, providing a seal by the operation of a flange which includes vacuum ports or adhesive material. Alternatively, sutures may be placed around the flange. Methods of using the sutureless vessel plug are also disclosed herein.

Claims Analysis
Total Claims: 32
Claim 1
Independent Claim
85 words
A vessel plug for maintaining hemostasis of a vessel having an opening, comprising: a handle having a proximal end, a distal end, and a vacuum tube; a flange attached to the distal end of the handle, the flange having a plurality of suction ports communicating with the vacuum tube; a vacuum source connected to the vacuum tube; and a tip that extends distally beyond the flange, the tip shaped to engage the opening in the vessel to block the flow of blood through the opening.
Claim 2
Dependent Claim
85 words
A vessel plug for maintaining hemostasis of a vessel having an opening, comprising: a handle having a proximal end, a distal end, and a vacuum tube; a flange attached to the distal end of the handle, the flange having a plurality of suction ports communicating with the vacuum tube; a vacuum source connected to the vacuum tube; and a tip that extends distally beyond the flange, the tip shaped to engage the opening in the vessel to block the flow of blood through the opening.
Claim 3
Dependent Claim
20 words
The vessel plug of claim 1, wherein the handle further includes a lumen which is closed at the distal end.
Claim 4
Dependent Claim
30 words
The vessel plug of claim 2, further comprising a preformed mandrel adapted for insertion into the lumen of the handle to adjust the angle of the tip relative the handle.
Claim 5
Dependent Claim
11 words

Claim 6
Dependent Claim
11 words
The vessel plug of claim 1, wherein the flange is H-shaped.
Claim 7
Dependent Claim
19 words
The vessel plug of claim 1, wherein the tip is deformable to engage an interior wall of the vessel.
Claim 8
Dependent Claim
22 words
The vessel plug of claim 1, wherein the tip operates to expand radially outward to engage an interior wall of the vessel.
Claim 9
Dependent Claim
21 words
The vessel plug of claim 1, wherein the flange has a curved profile to conform to the surface of a vessel.
Claim 10
Dependent Claim
16 words
The vessel plug of claim 6, wherein the deformation is actuated by struts and a spring.
Claim 11
Dependent Claim
15 words
The vessel plug of claim 6, wherein the deformation is actuated by an inflatable member.
Claim 12
Dependent Claim
29 words
The vessel plug of claim 6, wherein the tip comprises a shape memory material, and wherein the deformation is actuated by a phase transition within the shape memory material.
Claim 13
Dependent Claim
23 words
The vessel plug of claim 1, wherein the flange further comprises an adhesive on the surface which engages the wall of the vessel.
Claim 14
Independent Claim
86 words
A method for maintaining hemostasis of a blood vessel having an opening, comprising the steps of: providing a vessel plug comprising a handle, a flange attached to a distal end of the handle, and a tip that extends distally beyond the flange; inserting the tip into the opening on the vessel so that the flange engages the wall of the vessel, thereby blocking the flow of blood through the opening; suturing the vessel adjacent the flange; and removing the tip from the opening on the vessel.
Claim 15
Independent Claim
86 words
A method for maintaining hemostasis of a blood vessel having an opening, comprising the steps of: providing a vessel plug comprising a handle, a flange attached to a distal end of the handle, and a tip that extends distally beyond the flange; inserting the tip into the opening on the vessel so that the flange engages the wall of the vessel, thereby blocking the flow of blood through the opening; suturing the vessel adjacent the flange; and removing the tip from the opening on the vessel.
Claim 16
Dependent Claim
11 words
The method of claim 13, wherein the vessel is an artery.
Claim 17
Dependent Claim
11 words
The method of claim 14, wherein the artery is the aorta.
Claim 18
Dependent Claim
12 words
The method of claim 14, wherein the artery is a carotid artery.
Claim 19
Dependent Claim
27 words
The method of claim 13, further comprising the step of inserting a preformed mandrel into the handle to adjust the angle of the tip relative the handle.
Claim 20
Independent Claim
88 words
A method for maintaining hemostasis of a blood vessel having an opening, comprising the steps of: providing a vessel plug comprising a handle, a flange attached to a distal end of the handle, and a tip that extends distally beyond the flange; inserting a preformed mandrel into the handle to adjust the angle of the tip relative the handle; and inserting the tip into the opening on the vessel so that the flange engages the wall of the vessel, thereby blocking the flow of blood through the opening.
Claim 21
Independent Claim
