Abstract
Disclosed is a closure catheter, for closing a body cavity such as a vessel, or the left atrial appendage of the heart. The closure catheter includes a plurality of deployable tissue anchors, which may be laterally deployed into surrounding tissue. The anchors may thereafter be used to draw the tissue radially inwardly, to close the body cavity. Methods are also disclosed.
Claims6
A closure catheter for closing a body cavity, comprising:
- an elongate flexible catheter body, having a proximal end and a distal end, and a longitudinal axis extending therebetween;
- at least a first and a second anchor supports on the distal end, each comprising a tube, the anchor supports moveable between a first position in which they are substantially parallel with the axis, and a second position in which they are inclined laterally from the axis;
- at least a first and a second tissue anchors moveably positioned within the first and second tubes, respectively;
- and
- a control on the proximal end for moving the anchor supports from the axial orientation to the inclined orientation.
