Abstract: The medical device may comprise an elongate body having a proximal portion, a distal portion, and defining a lumen therethrough. Also, the medical device may include an expandable element coupled to the distal portion of the elongate body and in fluid communication with the lumen. The expandable element may define a first end and a second end, the second end being proximal to the first end. The medical device may further include a cannula surrounding at least a portion of the elongate body and the cannula may define a proximal end and a distal end. The distal end of the cannula may be disposed proximal and adjacent to the second end of the expandable element. An outer dimctcr diameter of the cannula may be substantially equal to or lesser than an outer diameter of the expandable element when inflated. The medical device may be maneuvered through a patient's body.

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: An implantable medical lead may include an electrode at a distal portion of the lead that is configured to monitor or provide therapy to a target site. The lead may include a visible indicator that is visible to the naked eye of a clinician at a medial portion of the lead that is configured to indicate when the electrodes of the lead are longitudinally and radially aligned properly to monitor or treat the target site. A clinician may insert the lead into the patient using an introducer sheath inserted to a predetermined depth into the patient and subsequently aligning the distal portion of the lead by orienting the indicator at an entry port of the introducer sheath.
