Abstract: An implant tool system includes an implantable medical lead and a delivery catheter. The implantable medical lead is configured to be delivered through an access point on a body of a patient. The delivery catheter is configured to deliver the implantable medical lead along an implantation path in the body of the patient. A visual marker is positioned on a body of the implantable medical lead. The visual marker is positioned proximal a distal end of the implantable medical lead by a distance indicative of a length of lead to introduce into the body of the patient. The visual marker may be positioned such that introduction of the length of lead into the body of the patient provides lead slack that reduces the likelihood of one or more of dislodgment of the implantable medical lead from the implant point or damage to a tissue of the patient.

Abstract: A medical device having an echogenic region facilitate guiding the medical device to a selected location within a patient using ultrasound. The medical device includes a first layer having a first polymer. The first layer defines an elongate body extending along a longitudinal axis from a proximal end to a distal end and defines a lumen extending longitudinally within the elongate body. The medical device further includes a second layer having a second polymer. The second layer is disposed on and radially adjacent to the first layer and defines the echogenic region. The echogenic region includes the second polymer and an echogenic metallic or ceramic material dispersed in the second polymer. The echogenic region is detectable using ultrasound imaging.
