Patent ID: 8864822

Claim:
A method of delivering respective anchors into spaced apart locations along an annulus of a mitral valve using a catheter device including at least first and second catheter members that respectively include at least first and second lumens, the method comprising: directing a first removable guide wire through the vascular system and into tissue of the heart of a patient; introducing the at least first and second catheter members through the vascular system and into the heart of the patient with the first guide wire received in the first lumen, thereby allowing the catheter device to move along the first guide wire, and while the at least first and second catheter members are in a collapsed state relative to one another; positioning distal end portions of the at least first and second catheter members proximate the annulus; expanding the distal end portions of the at least second catheter member laterally away from the first catheter member; delivering at least a second removable guide wire through the at least second lumen into tissue proximate the annulus while the distal end portions of the at least second catheter member remains expanded laterally away from the first catheter member; removing the catheter device from the heart while leaving the first and second removable guide wires in place within the heart; and subsequently delivering at least first and second anchors along the first and second removable guide wires, respectively, into the spaced apart locations along the annulus of the mitral valve; wherein the at least first and second anchors are delivered into the spaced apart locations along the annulus of the mitral valve after the first and second removable guide wires are positioned into the tissue of the heart of the patient.
