Claim 16

Independent Claim 151 words

A method for sealing a percutaneous incision or puncture in the wall of a blood vessel of a living being to preclude the flow of blood from said vessel through said incision or puncture by introducing plug means therein, said plug means having a shape which when said plug means is in place conforms to the arcuate inner surface of said vessel contiguous with said incision or puncture, said method comprising introducing said plug means into said vessel, with a portion of said plug means extending through said incision or puncture and causing said plug means to engage the arcuate inner surface of said vessel contiguous with said incision or puncture to seal said incision or puncture while not appreciably restricting the flow of blood through said vessel, and thereafter leaving said plug means in place therein, whereupon said incision or puncture is permanently sealed against the flow of blood therethrough.

Claim 17

Independent Claim 151 words

A method for sealing a percutaneous incision or puncture in the wall of a blood vessel of a living being to preclude the flow of blood from said vessel through said incision or puncture by introducing plug means therein, said plug means having a shape which when said plug means is in place conforms to the arcuate inner surface of said vessel contiguous with said incision or puncture, said method comprising introducing said plug means into said vessel, with a portion of said plug means extending through said incision or puncture and causing said plug means to engage the arcuate inner surface of said vessel contiguous with said incision or puncture to seal said incision or puncture while not appreciably restricting the flow of blood through said vessel, and thereafter leaving said plug means in place therein, whereupon said incision or puncture is permanently sealed against the flow of blood therethrough.
