MEDICAL LEAD ANCHORING

摘要

Various embodiments concern a lead system for anchoring a lead, the lead system comprising a lead and an anchor. The anchor can comprise a ring and a flange extending from the ring. The anchor can be mounted on the lead such that the lead extends through the ring and the flange extends over an electrode of the lead. The lead system can further comprise a tether having a proximal portion and a distal portion. The proximal portion of the tether can attached to the lead while the distal portion of the tether can be attached to a needle. During an implantation procedure, the tether can be cut to remove the needle. The tether can then be attached to the flange. The lead, the anchor, and the tether can form a loop around a section of tissue to anchor the lead to the tissue.

主权项

1. A lead system comprising:
an implantable lead, the lead comprising a proximal portion, a distal portion, a distal tip located on the distal portion, and at least one electrode located on the distal portion proximal of the distal tip; and an anchor, the anchor comprising a ring and a flange extending from the ring, the ring comprising a lumen, the anchor configured to be mounted on the lead such that the lead extends through the lumen while the ring is located proximally of the at least one electrode and the flange extends distally of the distal tip.
