EMBOLIC COIL DETACHMENT MECHANISM WITH FLEXIBLE DISTAL MEMBER AND RESISTIVE ELECTRICAL HEATING ELEMENT

摘要

PURPOSE: An embolic coil detaching device including a flexible distal member and a resistive electrical heating element is provided to easily treat an aneurysm by inserting coils to a target part through a catheter. CONSTITUTION: A flexible polymer tube includes a distal part. A long flexible pusher member (12) has a proximal part (20). An internal lumen (30) is extended through the flexible polymer tube. A resistive heating element (48) is adjacent to a score line and directly heats the distal part. [Reference numerals] (52) Power supply device; (54) Control unit
