Abstract: An implantable coaxial lead includes a cable with male and female connectors. The cable includes inner and outer helical coils separated by an inner insulator tube, with an outer insulator tube surrounding the outer helical coil. The male connector includes an outer conductive cylinder, a conductive pin and an insulator molded in between. For increased strength, a braided cylinder, infused with rubber, is included at the juncture of the male connector and the cable. The female connector includes a cylinder formed by two conducting body elements and an intervening insulating body element. The female connector includes respective conductive tension elements configured to engage the male connector. A first seal is provided between the conductive tension members for electrical isolation and tactile feedback. An insertion tool includes a cylinder with a hollow bore and detachable head, and a rod for pulling the lead through the cylinder.

Abstract: A sensing apparatus with a connector, a sensor lead and a sensor module with a spacer placed over electrodes that have been deposited on a substrate. The spacer may have a space for receiving an enzyme. End portions of the sensor module may be encapsulated, such as with molded beads. A sensor lead may attach to the sensor module and may have an outer tubing that passes over the module and attaches to the beads at the end of the sensor module. The sensor lead may also attach to the connector such that the sensing apparatus may be electrically coupled to a pump, electronics or other devices. The sensing apparatus may be implanted into a vein or artery.

Abstract: An in-line, multipolar proximal connector assembly for an implantable stimulation lead is provided which incorporates at least one sensor. Advantageously, the present invention uses straight conductive rods, or wires, to electrically connect the proximal terminals to a multilumen lead body. The straight conductive rods enable the diameter of the lead assembly to remain small. Additional terminals can easily be added by simply decreasing the spacing between terminals and adding additional conductive rods. In one embodiment, insulating spacers are premolded to include protruding portions which interlock with the ring terminals. Recesses within the insulating spacers are dimensioned to self-position the ring terminals a precise distance from the pin terminal according to precise dimensions defined by the VS-1 (or other) standards. In another embodiment, the terminals are injection molded.

Abstract: A universally mountable motor comprises an armature and first and second bearing brackets fitted to the armature at opposite faces thereof respectively and spanning a bore formed therein. A rotor is fitted in the bore and is supported to rotate in the bore by bearings mounted in the bearing brackets. The bearing brackets are secured to the armature by bolts, each of which has a threaded end which projects from one of the brackets. The first bracket is formed with wings which extend parallel to one another on opposite sides of the axis of rotation of the rotor and are formed each with at least one undercut slot. A screw can be fitted in the slot with a threaded portion projecting from the bracket to receive a stand-off.

Abstract: A universally mountable motor comprises an armature having first and second opposite faces and defining a cylindrical bore. First and second bearing brackets which span the bore are secured to the armature at the first and second faces respectively. Bearings mounted in the brackets define a common axis of rotation which is coaxial with the bore. A rotor is fitted in the bore and is supported by the bearings to rotate in the bore. The first bracket is formed with wings which extend over the first face of the armature on opposite sides of the axis of rotation. Each wing is formed with an elongate retaining slot defining a central axis and having a first region whereby a mounting member can be removably inserted into the slot and at least first and second additional regions which are spaced apart along the central axis of the slot and into which the mounting member can be selectively displaced from the first region to be captively retained in one of the additional regions.

Abstract: Integral posts on the molded base limit rotation of a lower contact carrier, and a contact guide limits rotation of an upper contact carrier, the carriers being spring biased for slidable movement on a lifter post attached to the armature of the relay.
