TISSUE-CAPTURED ANCHORS AND METHODS OF USE

摘要

Devices, systems and methods are provided for anchoring implantable medical devices to maintain an implanted position. In some embodiments, the medical devices are stimulation leads which are implanted near a portion of the neural anatomy for providing stimulation thereto. To maintain position of the lead, the lead is anchored with the use of a tissue-captured anchor which is attached to the lead at a desired point of anchoring. The anchor maintains position of the lead by resisting movement of the anchor between tissue layers at the point of anchoring.

主权项

1. An anchor for anchoring an elongate device within a body of a patient comprising:
an anchor body suturelessly attachable to the elongate device at an anchoring point and contoured so as to a) be positionable between a first tissue layer and a second tissue layer within the body while the elongate device passes through the first and second tissue layers, and b) atraumatically resist movement through the tissue layers thereby anchoring the elongate device between the tissues at the anchoring point.
