Adjustable medical electrode lead
First Claim
1. An implantable electrical lead, comprising:
- an elongated lead body carrying a conductor therein;
an elongated electrode extending from said lead body and coupled to said conductor within said lead body; and
an insulative tubular sheath mounted around said elongated electrode and slideable thereon, said sheath having a length less than that of the electrode and provided with means for facilitating its removal from the elongated electrode, said removal facilitating means comprising a weakened zone formed in said sheath.

Abstract
An implantable electrical lead having an elongated lead body carrying a conductor therein and an elongated electrode extending from the lead body and coupled to the conductor. The lead is provided with an insulative tubular sheath mounted around the electrode and slideable thereon, the sheath having a length less than that of the electrode. Optionally, the sheath is provided with a mechanism for facilitating its removal from the electrode, which may take the form of a weakened zone formed in the sheath. The lead may be provided with a plurality of insulative sheaths slidably mounted around the electrode, and each sheath is preferably provided with a mechanism for stabilizing the location of the sheath along the electrode, which mechanism may function to frictionally engage the sheath with the electrode or to compress the sheath around the electrode.
