摘要：
A reservoir of a system for deploying an implantable lead to an extravascular location delivers a flow of fluid through a lumen of one or both of a tunneling tool and an introducer of the system. In some cases, the tunneling tool includes a pressure sensor assembly for monitoring a change in a pressure of the flow through the lumen thereof. Alternately, or in addition, a flow-controlled passageway, through which the flow of fluid from the reservoir is delivered to the lumen of the introducer, includes a compliant chamber to hold a reserve of the fluid. Fluid from the reserve may be drawn into the lumen of the introducer as the tunneling tool is withdrawn therefrom. Alternately, the introducer may include a chamber located between two seals, wherein fluid that fills the chamber is drawn distally into the lumen of the introducer, as the tunneling tool is withdrawn therefrom.
