A connection system which has particular advantages in medical devices such as electrophysiology catheters, and which minimizes the potential for unwanted electrical connections. A cable of the invention has a plurality of leads, with each lead terminated by a pin connector having a retractable insulative sheath so that the chance of unwanted electrical connections is minimized when the pin connector is not connected. The metal pin of the pin connector also has a nonconducting tip member to minimize the chance of short circuits.

[ What is claimed is:] [1.] An improved method of performing a medical procedure using an electrophysiology device, which minimizes the potential for an electrode on the device to accidentally become electrically energized, comprisinga) providing an electrophysiology system comprisingan elongated electrophysiology device having a proximal end and a distal end, at least one electrode disposed about the distal end of the device;a cable with at least one electrical conductor extending through the cable, a distal end having a plug configured to mate with and provide electrical connection to the electrophysiology device, and a proximal end having at least one lead, the at least one lead being terminated by a pin connector having a housing with an opening and a lip, a conducting pin extending from the housing opening, a displaceable insulative sheath in surrounding relation to the conducting pin with a flange configured to intercept the housing lip, and a nonconductive tip member on the conducting pin; andan electronic interface having at least one receptor configured to mate with the pin connector;b) inserting at least a section of the pin in the receptor and thereby at least in part displacing the sheath so that the pin is in electrically conductive contact with the interface; andc) insulating the pin from electrical contact outside of the receptor by biasing the sheath to extend over the pin and a part of the nonconductive tip member which is less than the entire lengh of the nonconductive tip member when the pin and nonconductive tip member thereon are removed from the receptor so that the sheath extends over an electrically conductive portion of the pin when the portion of the pin is outside of the receptor.
