Catheter, sheath or dilator for heart valve decalcification treatment and method of use thereof

A deflectable sheath or dilator or catheter used for cardiac procedures comprising:

• a shaft with a proximal end and a distal end comprising one or more lumens running along a length of said shaft;
• an optical fiber located in one of said one or more lumens for use in channeling light used for visualization of calcification, heart tissue architecture or the progress of the cardiac procedure by performing 3D depth penetrating optical coherence tomography;
• wherein:
• said sheath or dilator or catheter further comprises an additional optical fiber for use as part of an ultrafast laser for calcium removal on or in heart valve tissue or for performing surgical intervention of the heart, said additional optical fiber running along a length of another of said one or more lumens;
• or
• said optical fiber is configurable for propagating a photon beam as part of an ultrafast laser for removing calcium on or in heart valve tissue or for performing surgical intervention of the heart;
• and
• a controller that is configured to:
• generate calcium density data by said performing optical coherence tomography, said calcium density data providing information on a location of a site for the surgical intervention or of the calcium deposit;
• and
• cause an adjustment of one or more of pulse duration, wavelength, focal distance, laser source of the ultrafast laser based on the calcium density data.
