摘要: A lead has a helix at a distal end of a rotatable shaft. Prior to implantation of the lead, the helix has a first configuration comprising an electrically active surface coated with an electrically insulative layer of a biologically dissolvable material to render the helix electrically inactive. Upon fixation of the helix into an organ, the helix has the first configuration and a pin is in electrical contact with the organ to detect proper fixation of the helix into the organ. Subsequent to fixation of the helix into the organ, the helix has a second configuration comprising an electrically active surface exposed upon dissolving of the electrically insulative layer of the biologically dissolvable material to render the helix electrically active.

摘要: A lead has an electrically controlled switch at a proximal end of a rotatable shaft. The electrically controlled switch has a first configuration to electrically connect a first electric conductor to a second electric conductor for electrically activating the pin and has a second configuration to electrically connect the first electric conductor to the rotatable shaft for electrically activating the helix. Proper fixation of the helix to an organ is determined by switching the electrically controlled switch to the first configuration to render the pin electrically active and to electrically deactivate the helix. Upon determination of proper fixation of the helix to the organ, the electrically controlled switch is switched to the second configuration to render the helix electrically active and to electrically deactivate the pin.

摘要: A lead comprises a mechanical switch at a proximal end of a rotatable shaft. The mechanical switch has a first position to electrically connect a first electric conductor to a second electric conductor for electrically activating a pin and has a second position to electrically connect the first electric conductor to the rotatable shaft for electrically activating a helix. Proper fixation of the helix to an organ is determined by inserting a stylet into the mechanical switch to render the pin electrically active and the helix electrically inactive. Upon determination of proper fixation of the helix to the organ, the stylet is removed from the mechanical switch to render the helix electrically active and the pin electrically inactive.
