Abstract: This disclosure provides tools and implant techniques utilizing such tools to gain access to and implant a medical device, such as a medical electrical lead, within extravascular spaces. In one example, this disclosure provides a tool for creating a sub-sternal tunnel in a patient. The tool comprises a relatively straight guide member extending from a first end thereof to a second end thereof, a tunneling member extending from a first end thereof to a tip thereof, the tunneling member extending alongside and coplanar with the guide member, the first end of the tunneling member and the first end of the guide member being joined together, and a handle coupled to the guide member.

Abstract: 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 extravascular locations, including subcutaneous locations. An example implant tool for implanting a medical lead includes a rod and a sheath configured to be placed on the rod. The rod includes a handle, a shaft having a proximal end adjacent to the handle and a distal end, and an attachment feature toward the distal end of the shaft, the attachment feature configured to couple to the medical lead. The sheath is configured to be placed in multiple positions along the rod including a first position in which the sheath does not interact with the attachment feature and second position in which the sheath does interact with the attachment feature.
