Abstract
An implantable catheter lead or electrode lead includes an elongated flexible lead body with the fixation means attached to the lead body, for the purpose of effecting fixation of the catheter lead or electrode lead in a predetermined position within a vessel or a bodily cavity of a patient. A releasable attachment is provided between the lead body and the fixation means such that an explantation of the catheter lead or electrode lead is possible after the attachment is released while the fixation means remains in place within the body of the patient.

14. An implantable lead for a catheter and/or an electrode, the lead including:
-
a. an elongated flexible lead body, and b. a fixator situated about at least a portion of a circumference of the lead body, wherein at least a portion of the fixator; (1) deploys circumferentially outwardly from the lead body, thereby engaging the walls of a vessel or cavity wherein the lead body and fixator are inserted; (2) is releasable from the lead body after deployment by falling from the circumference of the lead body, whereby release of the fixator from the lead body allows withdrawal of the lead body from any vessel or cavity wherein the lead body and fixator are inserted, without interference from the fixator. - View Dependent Claims (15, 16, 17, 18)

19. An implantable lead for a catheter and/or an electrode, the lead including:
-
a. an elongated flexible lead body, b. a fixator situated on the lead body, the fixator; (1) being movable between; (a) an undeployed state wherein one or more deployable portions of the fixator are situated in an initial location nearer an outer circumference of the lead body, and (b) a deployed state wherein the deployable portions are situated in a deployed location radially spaced from the outer circumference of the lead body, wherein the lead body is adapted, when situated within a human body, to have the fixator deployed to engage the human body, and thereby engage the lead body to the human body; (2) including an attachment to the lead body wherein the attachment destructs to release the fixator from the lead body, thereby allowing the lead body to be removed from the human body without interference from the fixator. - View Dependent Claims (20, 21, 22)
