An optical stimulation lead includes a lead body including a distal end, a distal portion, and a proximal portion; and an optical assembly attached to the distal end of the lead body. The optical assembly includes a light emitter; a feedthrough assembly including at least one ceramic block, at least one feedthrough pin extending through the at least one ceramic block and electrically coupled to the light emitter, and a metal housing attached to the at least one ceramic block; a metal tube attached to the feedthrough assembly and disposed around the light emitter; and an emitter cover disposed over the light emitter and coupled to the metal tube.

Implantable optical stimulation lead and methods of making and using

An Implantable Pulse Generator (IPG) operable as a Deep Brain Stimulator (DBS) is disclosed which is mountable to the skull of a DBS patient, and which therefore is much closer to the site of intended therapy. The IPG includes an electronics section, a charging coil section, a connector block section configured to connect to the proximal end of implanted leads, and an electrode wire section connecting the connector block section to the electronics section. The electronic section includes a housing that is positionable into a hole formed in the patient's skull. Once so positioned, the housing may be affixed to the skull via bone screws. The charging coil section may be separate from and non-overlapping with the electronics section, or the charging coil section may encircle the electronics section.

An electrical stimulation lead includes a stimulation cuff having an exterior surface and an interior surface that defines a nerve channel having a nerve channel axis. A plurality of electrodes are disposed on the interior surface of the cuff. A longitudinal opening extends through the cuff and further extends along an entire length of the cuff, wherein the opening is operable to receive a target nerve from a region outside of the cuff to within the nerve channel. A mount is disposed on the exterior surface of the cuff and radially offset from the nerve channel axis. A lead body is radially offset from the nerve channel axis and a plurality of conductors extend through the lead body, mount and cuff, with the plurality of conductors electrically coupled to the electrodes. The electrical stimulation lead may include a plurality of slots to permit tissue ingrowth.

Electrical stimulation cuff devices and systems

An implantable medical device for providing phototherapy to a patient's brain is disclosed. The device includes a housing containing a light source for providing phototherapy to a patient. A light path is attached to the housing. The implantable medical device is configured to be positioned between a patient's skull and scalp with the light path extending into the patient's brain, such that light from the light source can irradiate a target position within the patient's brain. The implantable medical device is powered and controlled by an implantable pulse generator (IPG) that may be implanted into a patient's tissue remotely from the device and connected to the device by wire leads.

Optical stimulation implant

An implantable pulse generator (IPG) allowing for trial stimulation in a fully implanted solution is disclosed. At the time the leads are implanted, a micro IPG having lead connection block(s) is also implanted and connected to the leads. To keep the micro IPG suitably small, it preferably does not include a battery, and is instead powered continuously via magnetic induction using a magnetic field produced by an external charger, such as a charging patch. A coil in the micro IPG picks up and rectifies this magnetic field to provide power to stimulating electronics in the IPG. Because of its small size (e.g., &#x2264;10 cm), implantation of the micro IPG can occur at the same time the leads are implanted in the patient without inconvenience. Should stimulation therapy with the micro IPG prove effective, a larger, permanent IPG can later be implanted and connected to the implanted leads.

A skull-mountable medical device is disclosed. The device includes a housing containing a light source for providing phototherapy to a patient. A light pipe is attached to the housing. The device is configured to be positioned on a patient's skull with the light pipe extending into the patient's brain, such that light from the light source can irradiate a target position within the patient's brain. Once so positioned, the housing may be affixed to the skull via bone screws. The device is powered and controlled by an implantable pulse generator (IPG) that may be implanted into a patient's tissue remotely from the device and connected to the device by wire leads.

A method of making a stimulation lead includes attaching multiple segmented electrodes to a carrier. Each of the segmented electrodes has a curved form extending over an arc in the range of 10 to 345 degrees. The method further includes attaching conductors to the segmented electrodes; forming the carrier into a cylinder with segmented electrodes disposed within the cylinder; molding a lead body around the segmented electrodes disposed on the carrier; and removing at least a portion of the carrier to separate the segmented electrodes.

Methods for making leads with radially-aligned segmented electrodes for electrical stimulation systems

A method of making an electrical stimulation lead method includes attaching a pre-electrode to a lead body. The pre-electrode is a single, unitary, undifferentiated construct with a ring-shaped exterior. The method further includes attaching a plurality of conductor wires to the pre-electrode; and, after coupling to the lead body, removing an outer portion of the pre-electrode to separate remaining portions of the pre-electrode into a plurality of segmented electrodes spaced around the circumference of the lead body. When separated, each of the segmented electrodes includes a body and at least one leg extending inwardly from the body. The body defines an external stimulating surface and each of the at least one leg has an outer surface. For at least one of the at least one leg, the outer surface of the leg forms a non-perpendicular angle with the external stimulating surface of the body.

Leads containing segmented electrodes with non-perpendicular legs and methods of making and using

Exemplary insertion tools for facilitating insertion of an electrode array into a bodily orifice include a stylet assembly having a stylet configured to be inserted into a lumen of the electrode array, a slide assembly configured to at least partially house the stylet assembly, and a handle assembly configured to engage at least a portion of the slide assembly. The slide assembly may be configured to selectively disengage from the handle assembly. The stylet assembly may be configured to selectively disengage from the slide assembly while the stylet is still inserted into the lumen of the electrode array. Corresponding systems and methods are also described.

Implantable or insertable medical devices

An implantable electrical stimulation lead includes a lead body, electrodes disposed along a distal end of the lead body, terminals disposed along the proximal end of the lead body, and conductors coupling the terminals to the electrodes. The electrodes include a tip electrode having an electrode body with an outer stimulating surface. An internal lumen is defined in the electrode body and extends inwardly from an opening in a proximal end of the electrode body. Side apertures are formed between the outer stimulating surface and the internal lumen. A portion of the lead body is disposed within the internal lumen and side apertures through the opening in the proximal end of the electrode body. That portion of the lead body facilitates retention of the tip electrode on a distal tip of the lead body.

Systems and methods for making and using tip electrodes for leads of electrical stimulation systems

A lead anchor includes an anchor body having a pin lumen and spaced-apart lead lumens extending along an entire length of the anchor body. The pin lumen receives an anchoring pin with a diameter that is larger than a diameter of the pin lumen. The pin lumen has flexible walls that exert a radially-outward-directed force away from the anchoring pin when the anchoring pin is received by the pin lumen. The lead lumens each have flexible walls and receive a different lead body of at least one lead. The radially-outward-directed force exerted by the walls of the pin lumen when the anchoring pin is received by the pin lumen causes corresponding radially-inward-directed forces along the flexible walls of the lead lumens that retain portions of the lead bodies within the anchor body when the portions of the lead bodies are received by the lead lumens.
