Abstract
An engagement catheter for use with a vacuum source for engaging a tissue. An embodiment of the engagement catheter includes a first lumen extending between a proximal end and a distal end, a skirt operatively connected to the distal end, the skirt having a distal end with a circumference larger than the outer circumference of the engagement catheter, a suction port located at or near the distal end of the engagement catheter, the suction port configured to allow the distal end of the skirt to removably engage a surface of a bodily tissue, and a vacuum port located at the proximal end of the engagement catheter and capable of operative connection to a vacuum source, wherein when a vacuum source is operatively attached to the vacuum port, the skirt is capable of forming a reversible seal with the surface of the bodily tissue.
