Abstract: A neurostimulation lead for stimulating neural tissue of a patient. The neurostimulation lead includes a lead body comprising insulative material, a plurality of electrodes, a plurality of terminals, a plurality of conductors. The plurality of electrodes may be electrically coupled to the plurality of terminals through coupling of the plurality of conductors which are disposed along a length of the lead body.

Abstract: A device and method consisting of conductive, non-conductive, and support materials. These materials when dispensed or extruded onto a multitude of temporary structures will create an implantable conductive and non-conductive structure suitable for neurological electrical stimulation and neurological electrical recording. This structure may also be suitable for delivering fluid and/or contain optical structures suitable for physiological sensing.

Abstract: An inflatable central distractor is inserted in to a disc space between two vertebral endplates. A perimeter balloon is inserted into the disc space in such a manner as to surround the central inflatable distractor. The perimeter balloon and the central inflatable distractor are simultaneously expanded such that as the central inflatable distractor expands the perimeter balloon surrounds the central inflatable distractor and such that the central inflatable distractor and the perimeter balloon, when expanded, contribute to forcing adjacent vertebral endplates apart.

Abstract: An apparatus for an image guided medical device, in at least one embodiment, provides uniform and continuous positioning of anchoring members to minimize or eliminate undesired tissue cutting or tearing. The apparatus includes a housing (40), a needle casing at least partially disposed in the housing and an anchor casing disposed at least partially disposed within the housing. A wheel (60) is disposed within the housing and is operatively engaged with and positioned between the needle casing and the anchor casing. An anchor assembly includes a tube with a proximal end coupled to the anchor casing and a distal end having an anchoring device (27). As the wheel (60) is rotated, the needle casing is drawn towards the wheel thereby retracting the needle and, simultaneously, the anchor casing is drawn toward the wheel thereby pushing the anchor assembly through the needle. The relative movement of the needle and the anchor assembly exposes an anchor member (27) in a uniform and continuous fashion.

Abstract: In various embodiments, a medical device includes an instrument head that includes a needle and two or more electrodes disposed on the needle; an impedance bridge coupled to the two or more electrodes; and a processor coupled to the impedance bridge. In various embodiments, a method for determining one or more tissue types present at a location associated with a needle of a medical device comprises recording, at one or more frequencies, one or more impedance measurements, wherein each impedance measurement is associated with two or more electrodes disposed on the needle of an instrument head of the medical device; comparing the one or more impedance measurements to one or more characteristic impedances associated with one or more tissue types; and determining, based on the one or more impedance measurements and the one or more characteristic impedances, one or more tissue types at the location associated with the needle.

Abstract: In various embodiments, a medical device includes an instrument head that includes two or more electrodes and a medical device tool, an impedance bridge selectively coupled to the two or more electrodes, and a processor coupled to the impedance bridge. In various embodiments, a method for controlling medical device tools comprises recording, at one or more frequencies, two or more impedance measurements, wherein each impedance measurement is associated with two or more electrodes included in an instrument head of a medical device; and determining, based on the two or more impedance measurements, a tissue type map at a location associated with the instrument head.
