Patent ID: 6951557

Claim:
A device for guiding a percutaneous myocardial revascularization cutting wire distal region to a plurality of heart chamber wall sites comprising: an elongate outer tube having a tubular wall and a distal region, said distal region wall having a plurality of channels therethrough; an elongate shape member on said outer tube and secured to said outer tube wall over at least said outer tube distal region, said shape member having a performed shape such that said outer tube distal region is biased to assume said shape member performed shape, and; means for stabilizing the position of said outer tube distal region within said heart chamber from within the heart, wherein the stabilizing means is magnetically responsive to an externally-generated magnetic field, such that said percutaneous myocardial revascularization cutting wire distal region can be advanced through said outer tube distal region wall channels to said heart chamber wall sites.
