Abstract: A length of tubing having an inside diameter equal to the diameter of a biomedical lead is slit along a direction parallel to its axis, with the length of the slits being equal to the desired circumference for lead anchor lobes. The tubing is slipped over the lead body and compressed so that the slit portions of the body expand into lobes, and while the tubing is compressed its ends are heated and compressed until they fuse to the lead body.

Abstract: A biomedical stimulation lead wherein the lead body is preformed into a helical configuration to assist in anchoring the lead. The lead includes a non-conducting member extending forward of the lead electrode along the axis of the lead body, and tines extending perpendicularly from the member. The tines are flat in a plane perpendicular to the axis of the lead.

Abstract: A body implantable connector for connecting a plurality of implantable devices, such as connecting an extension to a lead. There is a sheath having two open ends, one of which frictionally fits over the end of the lead and the other of which fits over the end of the extension. The sheath is of pliant material of sufficient strength to resist breaking under the forces normally exerted on the connector, but sufficiently pliable to deform and to contract about the lead and the extension under the frictional forces created between the sheath and the lead, and the sheath and the extension when the lead and the extension are urged in a direction tending to separate them. A wire extends longitudinally within the sheath and mates with lumens in the conductors of the lead and the extension to make electrical connection between the lead and the extension. There is a member within the sheath, intermediate the open ends of the sheath, and integrally formed with the sheath which supports the wire within the sheath.

Abstract: A circuit board is provided with a plurality of groups of connectors, so disposed and arranged in respect to each other that each group is capable of receiving a chip carrier. A fluid conduit, carrying a coolant, extends through each group so that when the contacts of a chip carrier are assembled to a group of connectors, a circuit chip, having a heat dissipating bar, is in close contact with the conduit. Conductors on each chip make electrical contact to the contacts on the chip carrier. A clip fastener is fastened to the carrier and includes bias means to bias the chip so that electrical connection is established between the chip contacts and the carrier contacts and thermal connection is established between the heat dissipating bar and the conduit.
