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.
Claims51
An anchor device configured to anchor an electrode lead to a fascia, the electrode lead configured to deliver electrical stimulation to a patient, the anchor device comprising:
- an anchor body, having a first lead fixing surface and a set of claws;
- a lead channel, extending through the anchor body, adjacent the first lead fixing surface;
- an endcap, having a second lead fixing surface, removably secured in the anchor body;
- whereby, the first lead fixing surface and the second lead fixing surface engage and prevent axial movement of the electrode lead;
- and,
- wherein the claws are adapted to secure the anchor body in the fascia.
A system for implanting an anchoring device for an electrode lead in a fascia, the system comprising:
- a barrel, having an interior surface and an exit portal adjacent the interior surface;
- a plunger, slidingly disposed within the interior surface;
- an anchor body, having a lead channel, positioned adjacent the exit portal;
- an endcap, positioned adjacent the interior surface and the plunger;
- wherein advancing the plunger in the barrel forces the endcap into the anchor body, thereby fixing the electrode lead in the lead channel and moving the anchor body through the exit portal.
An anchoring device configured to anchor an electrode lead to a fascia, the electrode lead configured to deliver electrical stimulation to a patient, the anchor device comprising:
- an anchor body, having a longitudinal passage;
- a first latitudinal lead channel formed in the anchor body;
- a barbed tube, positioned in the longitudinal passage, having a downwardly oriented set of anchor hooks;
- a lead stabilizer, positioned in the barbed tube, having a second latitudinal lead channel;
- an anchor cap, positioned adjacent the barbed tube and the lead channel;
- and,
- wherein the anchor cap compresses the second latitudinal lead channel.
A system for implanting an anchoring device for a percutaneous lead for an electrode in a fascia, the system comprising:
- a barrel, having an external surface, an internal surface and a storage bay;
- a plunger, slidingly disposed adjacent the internal surface, and adjacent the storage bay;
- a cartridge, slidingly disposed on the external surface;
- and,
- a lead anchor assembly, contained in the cartridge.
A method for implanting an anchoring device configured to secure an electrode lead to a fascia using a deployment tool, the deployment tool having a plunger and a barrel, the plunger having a spline, a lead access slot, a first detent ring and a second detent ring, the barrel having a third detent ring, and an exit portal, and housing the anchoring device and a locking cap, the anchoring device having a set of claws, a lead channel, a first lead fixing surface, and a set of interior threads, and the locking cap, attached to the plunger, having a second lead fixing surface, and a set of exterior threads, the method comprising:
- positioning the lead in the deployment tool against the fascia;
- inserting the lead through the lead access slot and the lead channel;
- advancing the plunger to move the locking cap into the lead channel, whereby the locking cap applies a force to secure the lead between the first lead fixing surface and the second lead fixing surface;
- and,
- inserting the anchoring device into the fascia.
A method of implanting a lead anchor assembly for an electrode lead in a fascia comprising the steps of:
- providing a barrel, having an external surface, an internal surface and a storage bay;
- providing a plunger, slidingly disposed adjacent the internal surface, and adjacent the storage bay;
- providing a cartridge, slidingly disposed on the external surface;
- providing a lead anchor assembly, having a lead channel, contained in the cartridge;
- positioning the electrode lead in the lead channel;
- positioning the barrel on the fascia;
- depressing the barrel toward the fascia, thereby advancing the cartridge on the barrel and deploying a set of hooks on the lead anchor assembly into the fascia;
- and,
- depressing the plunger toward the barrel thereby fixing the electrode lead in the lead anchor assembly.
