Abstract
Disclosed is a device for delivering tissue adhesives and/or sealant patches to a surface which covers or surrounds a lumen, cavity or organ, or potential lumen or cavity, within a human or other animal. Also disclosed is a method of delivering tissue adhesives and/or sealant patches to a surface which covers or surrounds a lumen, cavity or organ, or potential lumen or cavity. The method is particularly suited to sealing perforations in vascular walls, such as after arterial access for Percutaneous Transluminal Coronary Angioplasty (PTCA), Percutaneous Coronary Angiography and Percutaneous Coronary Atherectomy and similar diagnostic and therapeutic procedures.
Claims5
An applicator for percutaneously delivering a sealant patch to a surface of a perforated vascular wall, comprising:
- a tubular housing having a proximal end and a distal, atraumatic delivery end, said housing defining a reservoir for containing a volume of tissue adhesive and a recess which removably receives a patch, said reservoir being positioned proximal of said recess;
- a valve positioned in said housing between said reservoir and said recess to selectively place said reservoir in fluidic communication with said recess;
- and
- a control at the proximal end of the housing, for controlling the expression of adhesive from said reservoir and through said valve.
A kit for sealing a perforated vascular wall, comprising:
- an applicator having a reservoir, an atraumatic delivery end, a valve adjacent said delivery end which selectively places said reservoir in fluidic communication with said delivery end, and an actuator to open said valve;
- a sealant patch adapted to be coupled to the delivery end of said applicator;
- and
- tissue adhesive in said reservoir.
