摘要：
A tissue tunneling device (20) is configured to be delivered within the body.The tunneling device (20) includes a shaft (24) with a blunt distal end (60) toprevent coring or other damage to tissue during the delivery of the tunnelingdevice (20). The shaft (24), in some arrangements, includes one or more lumen(26), through which medication or another fluid may be administered. An anestheticor other pain relieving medication may be delivered through the lumen (26) tolessen the discomfort of delivering the tunneling device (20) to the desiredanatomical site. The shaft (24) may also include a retractable needle (70) forfacilitating the advancement of the tunneling device (20) through skin or othertissue. The shaft (24) may also be provided with an outer sheath (40), which maybe left within the anatomy after the tunneling device (20) has been removed. Theshaft (24) may be malleable for custom-shaping the tunneling device (20) priorto and/or during delivery.
