The bipolar screw-in pacing lead assembly is adapted to be mechanically secured to tissue of a body in an electrically conductive manner. The pacing lead assembly comprises an insulative tubular sheath having a distal end and a proximal end. First and second conductive members each having a distal end and a proximal end are received in and extend substantially the length of the tubular sheath. The first conductive member is insulated from the second conductive member. The pacing lead assembly further includes a distal electrode assembly at the distal end of the tubular sheath comprising a corkscrew attachment device which is electrically and mechanically connected to the second conductive member. A proximal terminal electrode assembly is coupled to the tubular sheath and includes (a) a cathode terminal pin/attachment member which is coupled by a brush contact to the second conductive member and which can be rotated to operate the corkscrew attachment device to secure the distal electrode assembly to tissue of the body and (b) a ring electrode having a brush contact adapted to make contact with the rotatable proximal end of the first conductive member.

The cardiac mapping lead comprises a main body portion and a tip portion having a tip. The main body portion is relatively flexible longitudinally and relatively stiff in a rotational sense so as to be torque transmitting when rotated. The tip portion includes a relatively flexible body having a preformed "pigtail" shape and one or more sleeve electrodes thereon. The torque transmitting main body portion can be rotated a predetermined amount at the proximal end thereof to effect like rotation of the tip portion in the heart chamber for placing the one or more pairs of sleeve electrodes against different, rotationally selected, inner wall surfaces of the heart chamber.

A ventricular catheter and a method for making same are provided wherein the catheter comprises a tubing assembly including a porous portion and a non-porous portion. The porous portion has a high surface density of very fine pores which are substantially resistant to blockage under in vivo conditions yet allow cerebrospinal fluid to pass therethrough when the assembly is attached to a cerebrospinal fluid pressure relief system for the treatment of hydrocephalus. The porous portion is generally formed by extruding a fiber forming polymer which is wound directly onto a mandrel.
