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.
Claims10
An adhesive patch applicator kit, comprising:
- a housing having a rotatable cap, said housing having a chamber therein, said cap rotatable about a longitudinal axis of the housing;
- an applicator within the chamber, said applicator removably connected to one of the housing or the rotatable cap;
- a reservoir in the chamber, said reservoir connected to the other of the housing or the cap;
- a tip on the reservoir for expressing adhesive from the reservoir;
- and
- an adhesive patch removably attached to the applicator in between the applicator and the tip;
- wherein rotation of the cap relative to the housing about the longitudinal axis expresses adhesive from the reservoir through the tip and on to the patch.
A method of closing a vascular perforation of the type produced during a percutaneous transluminal catheterization procedure, comprising the steps of:
- providing an adhesive patch applicator kit of the type having a housing with a first portion that is rotatable with respect to a second portion, said housing having an applicator therein with an adhesive patch on the applicator, said housing further having an adhesive reservoir therein with an applicator tip for expressing adhesive from the reservoir onto the patch;
- rotating the first portion of the housing with respect to the second portion of the housing to express an annular bead of adhesive from the reservoir and onto the patch;
- removing the applicator having the patch thereon from the housing;
- advancing the applicator percutaneously to position the patch against the vascular perforation;
- and
- removing the applicator while leaving the patch adhered to the vascular perforation.
