Abstract: A tissue tunneling device is configured to be delivered within the body. The tunneling device includes a shaft with a blunt distal end to prevent coring or other damage to tissue during the delivery of the tunneling device. In some arrangements, the shaft includes one or more lumen, through which medication or another fluid may be administered. An anesthetic or other pain relieving medication may be delivered through the lumen to lessen the discomfort of delivering the tunneling device to the desired anatomical site. The shaft may also include a retractable needle for facilitating the advancement of the tunneling device through skin or other tissue. The shaft may also be provided with an outer sheath, which may be left within the anatomy after the tunneling device has been removed. The shaft may be malleable for custom-shaping the tunneling device prior to and/or during delivery.
