IMPLANTABLE MEDICAL LEAD WITH BLOOD SEAL |
摘要 |
An implantable medical lead comprises an insulating tubing with a channel housing a conductor electrically connected to a shaft present in a lumen of a bearing. The shaft is also connected to a fixation helix present in a lumen of a lead header. A clot-inducing structure of a thrombogenic material is present in a distal portion of the channel and/or in the lumen of the bearing to trigger formation of a clot when blood enters the implantable medical lead and thereby inhibit blood from entering further into the channel. |

1. An implantable medical lead comprising:
an insulating tubing having a channel with a distal channel portion and an opposite proximal portion; a lead header having a lumen; a bearing having a lumen; a fixation helix at least partly present in the lumen of the lead header and having a first end; a shaft at least partly present in the lumen of the bearing and having a first end mechanically connected to the first end of the fixation helix and a second end; and a conductor at least partly present in the channel and having a first end electrically connected to the second end of the shaft, wherein a first clot-inducing structure of at least one thrombogenic material is present i) in the distal channel portion or ii) in the lumen of the bearing to trigger formation of a blood clot when blood enters the implantable medical lead and thereby inhibit blood from entering further into the channel towards the opposite proximal portion. |
