An insertion kit for percutaneously implanting an electrical stimulating paddle lead into a patient includes a paddle lead introducer. The paddle lead introducer facilitates percutaneous implantation of a paddle lead into the patient. The paddle lead introducer includes a sheath and a dilator. The sheath is insertable into the patient. The sheath is configured and arranged to receive a paddle lead during implantation of the paddle lead into the patient. The sheath can divide into at least two parts for removal of the sheath from the paddle lead upon implantation of the paddle lead. The dilator is insertable into the sheath. A first end of the dilator defines an aperture at a tip of the first end. The first end of the dilator has a transverse circumference that increases from the tip towards a second end.

A method for manufacturing a lead includes pre-forming at least one relief section along a length of an elongated conductor having a first end and an opposing second end. The conductor with the pre-formed relief section is inserted into a conductor lumen defined along a length of an elongated lead body. The lead body has a first end and an opposing second end. An electrode is disposed at the first end of the lead body. The first end of the conductor is electrically coupled to the electrode. A terminal is disposed at the second end of the lead body. The second end of the conductor is electrically coupled to the terminal.

A multi-lead introducer for facilitating implantation of stimulation leads includes a needle assembly for concurrently implanting multiple leads into a patient. The needle assembly includes a first needle with a first needle lumen configured to receive a first lead. A first sharpened tip is disposed along a first end of the first needle for piercing patient tissue. A second needle defines a second needle lumen configured to receive a second lead. A second sharpened tip is disposed along a first end of the second needle for piercing patient tissue. A hub is coupled to second ends of both the first needle and the second needle. The hub defines a hub lumen that is in communication with both the first needle lumen and the second needle lumen. The hub lumen is configured to concurrently receive both the first lead and the second lead.

An implantable lead assembly for providing electrical stimulation to a patient includes a lead body; a terminal disposed along a proximal end of the lead body; and an orthopedic implant coupled to a distal end of the lead body. The orthopedic implant is configured and arranged for anchoring to a bony structure. At least one mounting region is disposed along the orthopedic implant. The at least one mounting region is configured and arranged for anchoring the orthopedic implant to the at least one bony structure. An electrode is disposed along a stimulation region of the orthopedic implant. A conductor electrically couples the terminal to the electrode.

An exemplary steerable stylet handle assembly includes a housing having first and second side walls defining a channel therebetween, a button in communication with the first and second side walls and configured to move distally and proximally within the channel, and a stylet subassembly having an inner stylet wire located at least partially within an outer tubing. The inner stylet wire has a pre-curved portion and is coupled to a proximal portion of the housing. The outer tubing is coupled to the button. Movement of the button within the channel is configured to selectively expose and cover at least a portion of the pre-curved distal portion of the inner stylet wire with the outer tubing.
摘要:
A lead anchor includes a body defining a lead lumen having a first opening and a second opening through which a lead can pass. The body further defines a transverse lumen that intersects the lead lumen. An exterior member is disposed around at least a portion of the body. The exterior member is formed of a biocompatible material. A fastener anchors the lead to the body through the transverse lumen by deforming a portion of the lead. The transverse lumen is configured and arranged to receive the fastener. At least one suture element is defined by the exterior member and is configured and arranged for receiving a suture to suture the lead anchor to patient tissue.
