Abstract:

A steerable multi-lumen catheter is provided which can be used in cardiology procedures where the catheter allows clinicians to access the small pulmonary arteries for monitoring and performing interventional procedures. The catheter allows precise changes in direction and simplifies challenging navigation procedures such as crossing a thick and calcified aortic valve with a wire. A bendable tip aids navigation during interventional radiology and neurology procedures to enter tortuous vessels or aneurysms.
