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 The balloon is inflated and withdrawn until it engages the inner surface of the blood vessel.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 After a predetermined time period, the balloon is deflated and the device is withdrawn.

Vascular sealing apparatus

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 The balloon is inflated and withdrawn until it engages the inner surface of the blood vessel or body cavity. The sheath is withdrawn from within the blood vessel or other body cavity to the outside of the body.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.

Vascular sealing device

A procoagulant designed to effect hemostasis at a puncture site in a patient's vasculature without the aid of manual compression is comprised of lyoplilized thrombin that is reconstituted with a buffered diluent and collagen that is mixed with the reconstituted thrombin to produce a viscous mixture. The buffered diluent is preferably of sodium phosphate and water. The procoagulant is essentially isotonic and has a pH in the range of 5-10. The method of making the procoagulant is comprised of the steps of reconstituting the lyophilized thrombin with the buffered diluent and then, mixing the reconstituted thrombin with collagen to both reduce the size of the particles of the collagen and form a fluid mixture.

Thrombin and collagen procoagulant and process for making the same

A vascular sealing device for effecting closure of a puncture or other opening in a blood vessel, or other body cavity, which has been entered through percutaneous techniques. The device is useable with a standard percutaneous vascular introducer. The vascular sealing device generally comprises a body or shaft, an adapter disposed at a proximal end of the shaft, and a balloon portion disposed generally at a distal end of the shaft. A core wire is connected to the distal end and extends, internally, through a lumen of the device for deflation of the balloon. A procoagulant is introduced through the introducer, or alternatively through an additional lumen and associated apertures, and to the puncture sealed by the inflated balloon. Subsequently, the balloon is deflated and the device is removed from the sealing puncture, with or without the aid of a reaccess sheath.
