SYSTEMS AND METHODS FOR IMPLANTING A MEDICAL ELECTRICAL LEAD

摘要

Implant tools and techniques for implantation of a medical lead, catheter or other implantable component are provided. The implant tools and techniques are particularly useful in implanting medical electrical leads in implant locations such as substernal spaces or subcutaneous locations. The implant tools include a sheath coupled to a sealing device. The sheath includes a continuous lumen that is in fluid communication with a passage of the sealing device. The lead is advanced through the passage and the lumen for placement of the distal end of the lead at the implant location.

主权项

1. A method of delivering an implantable medical system, comprising:
providing a delivery system comprising a sheath having a lumen and a sealing assembly having a passage that is in fluid communication with the lumen, and an elongate tool disposed within the lumen and the passage; creating an access point into a substernal space of a patient; inserting the delivery system through the access point into the substernal space; orienting a distal portion of the delivery system towards a sternum of the patient; advancing the delivery system through the substernal space to a predetermined implant site; generating with the distal terminal end a signal indicative of a location of the distal portion relative to the sternum during the task of advancing; removing the elongate body from the lumen and the passage and inserting a lead through the passage into the lumen; advancing the lead of the implantable medical system to position a distal end of the lead at the predetermined location; and positioning an electrode coupled to the distal end of the lead in a predetermined orientation within the substernal space.
