The present invention provides an apparatus and a method for quickly and effectively sealing an arteriotomy site in a patient. In particular, the invention provides an apparatus and a method for sealing an arteriotomy site which can be performed by a single operator. The arteriotomy can be sealed by delivery of a patient specific autologous fibrin glue to a debrided, synthesized area adjacent to the extravascular opening of the arteriotomy.
An apparatus for sealing an arteriotomy site in a patient comprising: a. a first elongated flexible catheter having a proximal end, a distal end, an external surface, and a wall portion defining at least one lumen extending substantially the entire length of said first catheter, and at least one ope
An apparatus for sealing an arteriotomy site in a patient comprising: a. a first elongated flexible catheter having a proximal end, a distal end, an external surface, and a wall portion defining at least one lumen extending substantially the entire length of said first catheter, and at least one opening through the external surface of said first catheter located adjacent the distal end, whereby a proximal end of at least one lumen is in fluid communication with the external surface of said first catheter via said opening; b. means located adjacent the distal end of said first catheter for temporarily occluding an intravascular opening of the arteriotomy site when said occluding means is positioned in an intravascular space of the patient\s artery proximate to the arteriotomy site; c. a second elongated flexible catheter having a front end, a rear end, an outer surface a body portion, and a central bore defined by the body portion extending through the length of said second catheter communicating the front end with the rear end; d. means located on said second catheter for debriding subcutaneous tissue from an exterior surface of the anterior arterial wall proximate to the arteriotomy site; and e. means located on a selected one of said catheters for delivering a material to the arteriotomy site that is capable of forming a substantially fluid tight seal of the arteriotomy site.
