| titleOfInvention | Steerable catheter with preformed distal region and method for use |
| abstract | A catheter has a stylet formed of a shape-retentive and resilient material having a preformed curved shape at its distal end resulting in the catheter sheath having the preformed curved shape. The catheter sheath has a plurality of electrodes at its distal end for contacting selected biological tissue for imparting ablation energy thereto. The catheter sheath also has an axially mounted tendon for causing deflection of the distal end. The stylet material permits straightening the catheter sheath during insertion into the patient and advancing the electrodes to the target tissue. Upon removal of the straightening forces, such as by entry into a chamber of the heart, the stylet material resumes its preformed curved distal shape thereby forcing the catheter distal end withthe electrodes into the same preformed curved shape. The operator may place the curved distal end into contact with the target tissue and axially move the tendon as desired to gain greater control over the bend in the distal end of the catheter sheath to adjust the radius of curvature of the distal end to obtain greater contact of the electrodes with the heart tissue. Preferably, the stylet is formed of nitinol. |
