Abstract: A rail and/or anchor system and method for transjugular intrahepatic portosystemic shunt procedures. The system includes a rail line that is anchorable to surrounding tissue and used as a rail to guide the displacement of at least one needle and an outer sheath. The rail line may include an inflatable balloon that is configured to selectively anchor the anchor line to surrounding tissue by the balloon being inflated and unanchor the anchor line to surrounding tissue by the balloon being deflated. The rail line is stiff. The rail line includes a lumen and is configured for executing wedge venography, and for measuring pressure at a tip of the rail line while a balloon of the balloon catheter is inflated. The anchor line may include one or more hooks for anchoring the anchor line to surrounding tissue. The one or more hooks may be selectively advanceable and retractable.

Abstract: The invention described is comprised of a system and method for rapid fixation of a lead anchor. The system includes a lead anchor and insertion device. The insertion device houses a lead anchor. A lead is threaded through the insertion device and the device is depressed against the fascia to insert the lead anchor and fix the lead in the desired position. This method produces repeatable amount of lead body compression grasp force, and controlled bend radius. This results in rapid lead anchoring, lowers the risk of lead migration, prevents mechanical damage to the lead due to over-compression and eliminates the need for tying a suture.
