SUBCUTANEOUS LEAD GUIDANCE

摘要

An apparatus for subcutaneous lead guidance includes a flexible guide strap (130), a navigation catheter (150) and a tunneling tool (110). The guide strap includes an upper layer (134) having a plurality of retainer formations (136) and a substrate (132) attachable on a patient's skin extending between an incision (80) and a target site (84). The navigation catheter is coupled to the upper layer via the retainer formations from a first end (130a) to a second end (130b) of the guide strap. The navigation catheter includes a plurality of position sensors (140) for generating a subcutaneous navigation volume (170) between the incision and the target site when the navigation catheter is coupled to a navigation system (10). The tunneling tool has a distal portion (116) with a leading end (112) and at least one position sensor on the distal portion for viewing digital representation of the distal portion in relation to the navigation volume on a display (36) coupled to the navigation system.
