Abstract
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 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 typically placed through a vascular 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 The balloon is inflated and withdrawn until it engages the inner surface of the blood vessel or body cavity. The sheath is withdrawn from within the blood vessel or other body cavity to the outside of the body. A fixation collar loaded onto the shaft of the device allows for securement in place, within the blood vessel or other body cavity.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
248 words
A vascular sealing system for closing a percutaneous puncture in a patient's vasculature, comprising: (a) a hemostasis valve-type vascular introducer member having a thin, substantially straight body with central lumen of a predetermined inside diameter; and (b) a vascular sealing member adapted for insertion into and retraction from said central lumen of said vascular introducer member, said vascular sealing member comprising: (i) a thin, straight elongated conduit having an outside diameter slightly less than said vascular introducer member central lumen inside diameter, and a central lumen, said conduit having proximal and distal ends, said outside diameter being uniform from said proximal end to said distal end whereby said vascular sealing member is slidable in said vascular introducer member internal lumen throughout its whole length for proximal withdrawal of said vascular introducer member over said vascular sealing member without splitting of said introducer, 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, said conduit proximal end having a cylindrical configuration of a uniform outside diameter; (ii) an expandable member sealingly disposed at said conduit distal end inflation segment, said expandable member being inflatable to a predetermined diameter; and (iii) a seal consisting of an elastomeric material continuously and adhereingly disposed in said conduit central lumen along a predetermined segment at said proximal end thereof, said seal permitting ingress and egress of fluid to and from said conduit lumen via a syringe.
