Abstract
An implantable endocardial defibrillation lead having an elongated lead body with multiple lumens therein. Windows, cut through the lead body, provide access to selected ones of the lumens at selected locations along the lead body. In addition, a method and an apparatus for forming windows in a multilumen lead body are disclosed. A ferromagnetic stylet is inserted into a selected lumen. The lead body is oriented in a jig by application of an electromagnetic field. A grinder or punch cuts a window into the selected lumen.
Claims8
An apparatus for cutting windows into at least one lumen of a lead body having multiple lumens therein, the apparatus comprising
- a jig for supporting an elongated, flexible lead body;
- a magnetic field generator mounted at a selected orientation with respect to said jig, where the magnetic field generator is adapted to attract a stylet in one of the multiple lumens of the lead body;
- and
- a cutter mounted at a selected orientation with respect to said jig for cutting said window.
