Abstract
Disclosed is a device for delivering tissue adhesives to a surface which covers or surrounds a lumen, cavity or organ, or potential lumen or cavity, within a human or animal. Also disclosed is a method of delivering tissue adhesives to a surface which covers or surrounds a lumen, cavity or organ, or potential lumen or cavity, within a human or animal. 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.
Claims8
A device for percutaneously delivering a tissue adhesive to a surface of a vascular wall surrounding a perforation in the vascular wall, comprising:
- a tubular housing having a proximal control end and a distal delivery end;
- a reservoir in the housing for containing a volume of tissue adhesive;
- an applicator on the distal delivery end of the housing, said applicator further comprising a guidewire lumen extending axially therethrough;
- and
- a control on the proximal control end of the housing for controllably expressing adhesive from the reservoir to the applicator;
- wherein said applicator comprises at least one, substantially smooth, atraumatic delivery surface facing in the distal direction in fluid communication with the reservoir for applying tissue adhesive to the surface of the vascular wall surrounding the perforation in the vascular wall.
