A clamp has a handle assembly, a gripping assembly having a pair of jaws that can be opened and closed to grip an element, and a shaft assembly. The shaft assembly has a flexible shaft having a proximal end that is coupled to the handle assembly and a distal end that is coupled to the gripping assembly. The flexible shaft also defines a bore that retains a cable which is operatively coupled to the handle assembly and to the gripping assembly. The shaft assembly also includes a retractable generally rigid covering which can be oriented in a first position where the covering exposes a portion of the flexible shaft, and in a second position where the covering completely covers the flexible shaft.

The catheter of claim 10, wherein the third lumen is defined by a third wall, where the third wall has a lubricious coating. 15. A catheter comprising: an elongate catheter body having a proximal end and a distal end, where the elongate catheter body includes a first section, a second section and a tapered region between the second section and the first section, the first section extending between the tapered region and the distal end and the second section extending between the proximal end and the tapered region, the tapered region positioned between the proximal and the distal ends of the elongate catheter body; a first lumen adapted to pass a cardiac lead, the first lumen extending between a first inlet at the proximal end of the catheter body to a first outlet at the distal end of the catheter body; a second lumen adapted to pass a cardiac lead, the second lumen extending through the second section of the elongate catheter body between a second inlet at the proximal end of the elongate catheter body to a second outlet in the tapered region; and wherein the elongate catheter body is adapted to separate into three or more segments. 16. The catheter of claim 15, wherein the three or more segments of the elongate catheter body are defined by slits extending longitudinally along the catheter body. 17. A system comprising: a catheter, the catheter including: an elongate catheter body having a proximal end and a distal end, where the elongate catheter body includes a first section, a second section and a tapered region between the second section and the first section, the first section extending between the tapered region and the distal end and the second section extending between the proximal end and the tapered region, the tapered region positioned between the proximal and the distal ends of the elongate catheter body; a first lumen adapted to pass a cardiac lead, the first lumen extending through the first section of the elongate catheter body between a first inlet at the proximal end of the catheter body to a first outlet at the distal end of the catheter body; and a second lumen adapted to pass a cardiac lead, the second lumen extending through the second section of the elongate catheter body between a second inlet at the proximal end of the elongate catheter body to a second outlet in the tapered region; a first cardiac lead, where at least a portion of the first cardiac lead is located in and passes through the first lumen of the elongate catheter body; and a second cardiac lead, where at least a portion of the second cardiac lead is located in and passes through the second lumen of the elongate catheter body. 18. The system of claim 17, wherein the first lumen is defined by a first wall and the second lumen is defined by a second wall, where the first and second wall each have a lubricious coating. 19. The system of claim 17, wherein the elongate catheter body is made radiopaque. 20. The system of claim 17, wherein the elongate catheter body is adapted to separate into two or more segments. 21. The system of claim 20, wherein the two or more segments of the elongate catheter body are defined by slits extending longitudinally along the catheter body. 22. The system of claim 17, including a third lumen extending through the first section between a third inlet at the proximal end to a third outlet at the distal end of the catheter body; and a third cardiac lead, where at least a portion of the third cardiac lead is located in and passes through the third lumen of the elongate catheter body. 23. The system of claim 22, wherein the third lumen is defined by a third wall, where the third wall has a lubricious coating. 24. The system of claim 22, wherein the elongate catheter body is adapted to separate into three or more segments. 25. The system of claim 24, wherein the three or more
