    • An apparatus and method for an electrical stimulation lead having a selectively variable length. In an embodiment of the invention, an apparatus includes a conducting element, a stimulating electrode, a pickup electrode and a sheath. The conductive element has a proximal end, a distal end and a length which is defined between the proximal and distal ends. The stimulating electrode is coupled to the distal end of the conductive element and the pickup electrode is coupled to the proximal end of the conductive element. The sheath of the apparatus is configured to enclose at least a portion of the conductive element. The sheath has a reconfigurable portion that is able to move between a first configuration and a second configuration. The sheath has a first length when in the first configuration and a second length when in the second configuration.
    • 一种具有选择性可变长度的电刺激引线的装置和方法。 在本发明的实施例中,一种装置包括导电元件,刺激电极,拾取电极和护套。 导电元件具有近端,远端和限定在近端和远端之间的长度。 刺激电极耦合到导电元件的远端,并且拾取电极耦合到导电元件的近端。 装置的护套被构造成包围导电元件的至少一部分。 护套具有能够在第一配置和第二配置之间移动的可重新配置部分。 当处于第一构造时,护套具有第一长度,并且当处于第二构造时具有第二长度。
