Vascular sealing apparatus
First Claim
1. A method for closing of an aperture in a patient'"'"'s blood vessel through an introducer predisposed in the blood vessel aperture, the introducer being of a type having an axial lumen opening to a distal insertion end adapted for location in the blood vessel aperture, and a fluid injection port being communicatively connected to the introducer lumen;
- comprising the steps of;
a. providing a medical sealing apparatus, comprising;
i. a thin, elongated conduit having a central lumen, said conduit having proximal and distal ends, said conduit distal end being insertable into the patient body aperture and having an inflation segment including an external orifice which is communicatively connected to said lumen;
ii. an expandable member sealingly disposed at said conduit distal end inflation segment, said expandable member being inflatable to a predetermined diameter; and
iii. means to connect said conduit lumen to an external inflation source, said means to connect being disposed at said proximal end of said conduit;
b. inserting said apparatus through the introducer lumen and into the blood vessel aperture, said apparatus conduit being extended through said introducer lumen so that said apparatus expandable member is disposed outwardly beyond said introducer distal insertion end;
c. inflating said expandable member;
d. moving said expandable member into contact with the blood vessel aperture; and
e. introducing procoagulant into said introducer lumen via said fluid injection port and distributing said procoagulant out said distal insertion end.

Abstract
A device for sealing an opening or puncture in the wall of a blood vessel or other percutaneous openings. The device includes a shaft section member of a small diameter, with an expandable balloon and atraumatic tip at its distal end. The proximal end of the device has an inflation/deflation port which is utilized to inflate the balloon once it is in place within the blood vessel or other body cavity. The entire device is placed through a hemostasis vascular introducer or sheath, which is used during invasive percutaneous vascular procedures. The balloon is inflated and withdrawn until it engages the inner surface of the blood vessel. A procoagulant is injected via the introducer to the puncture. After a predetermined time period, the balloon is deflated and the device is withdrawn.
