Variable stiffness magnetic catheter United States Patent 06524303

06524303 is referenced by 136 patents and cites 1 patents.

A steerable magnetic catheter having a proximal end, a distal end, and a lumen therebetween. The catheter has regions of different flexibility along its length. There is a magnetic body adjacent the distal end, which is responsive to an applied magnetic field. The magnetic body is sized and the flexibility of the distal end portion of the catheter is selected so that the distal end of the catheter can be manipulated with a magnetic field of a practical strength, eliminating the need for a guidewire.
