Abstract: A steerable multi-polar lead shaft assembly includes a core member extending longitudinally through the shaft assembly, a plurality electrically conductive elements disposed within the core member, a plurality of steering wires circumferentially distributed about the core member. A control mechanism for a steerable catheter, such as the steerable multi-polar lead assembly, includes a mounting portion adapted to engage a steerable shaft, a stem extending from the mounting portion, a swivel joint arranged at a proximal end of the stem, a control yoke rotatably mounted on the swivel joint, adapted to engage a plurality of steering wires of the steerable catheter, and a handle connected with the yoke, adapted for direct manipulation by a user.

Abstract: An electrical connector is disclosed that includes an annular housing having a central aperture for receiving a connector pin and an annular contact spring disposed concentrically within the annular housing and including a plurality of circumferentially spaced apart spring arms, each spring arm having a radially inwardly extending contact pad for resiliently contacting a connector pin inserted into the central aperture of the housing.

Abstract: A peelable vascular introducer including an elongated tubular sheath having opposed proximal and distal ends and at least three circumferentially spaced peel lines extending from the proximal end to the distal end. The peelable vascular introducer also includes spreadable handles associated with the proximal end of the sheath configured to split the sheath along the peel lines.

Abstract: A vascular introducer assembly is disclosed that includes a dilator, a sheath having an axial lumen for accommodating the dilator, a locking collar for securing the dilator and the sheath to one another and an adjustable hemostatic seal for preventing fluid egress from the axial lumen and restricting insertion of instruments through the axial lumen.
