    摘要： Methods and systems for treating patients requiring tissue ablation for volumetric tissue reduction rely on the injection of ethanol and other tissue-ablating agents into the perivascular space surrounding body lumens, particularly blood vessels or vessels of the alimentary canal, reproductive system and urinary tract. Injection of tissue-ablating agents is intended treat conditions such as hypertrophic cardiomyopathy, benign and malignant tumors, benign prostatic hyperplasia, and uterine fibroids, for example. Injection may be achieved using intravascular catheters which advance needles radially outward from a body vessel lumen or by transmyocardial injection from an epicardial or endocardial surface of the heart.

    摘要： A torque mechanism for interventional catheters provides direct control over rotary positioning of the distal end of a catheter by rotating a proximal handle of the catheter. The torque mechanism comprises a stiff tube within and running the length of a flexible catheter body tube. The stiff tube is bonded at its distal end to the catheter body tubing and at its proximal end to a rotary handle. Catheter body tubing is bonded at its proximal end to a catheter hub. The catheter hub and rotary handle rotate independently, thus torque and position are transmitted by the torque tube while the catheter tube acts as a torsional spring.
