US 2010/0076408 A1 · DEFLECTING GUIDE CATHETER FOR USE IN A MINIMALLY INVASIVE MEDICAL PROCEDURE FOR THE TREATMENT OF MITRAL VALVE REGURGITATION

Abstract

A deflecting guide catheter for use in minimally invasive medical procedures such as the treatment of mitral valve regurgitation by reshaping the mitral valve annulus using one or more plications of annular or adjacent tissue each fixed by a retainer is described. The catheter includes an elongated tubular portion having various durometers along its length and at least one puller wire attached to an anchor band near the distal end. The deflecting guide catheter is used to provide a means for guiding a plication device or other medical instrument into a desired position within the vasculature or heart chambers of a patient.

Dependent claims

A deflecting guide catheter for guiding a medical device through a lumen of a patient during a medical procedure comprising:

an elongated tubular body portion having a lumen and a distal end and proximal end;
an anchor band near the distal end of the elongated tubular body portion;
a handle assembly attached to the proximal end of the elongated tubular body portion wherein the handle assembly comprises an actuator assembly;
and,
a puller wire connected from the actuator assembly to the anchor band wherein movement of the actutator assembly in a proximal direction causes proximal movement of the puller wire and deflection of the distal end of the deflecting guide catheter.
