MEDICAL DEVICE ANCHORING SYSTEMS AND METHODS

摘要

An anchor assembly (500) includes an anchoring member (510) having a body portion. The anchoring member defines a longitudinal lumen in the body portion to slidably receive a portion of an electrode assembly. The anchor assembly also includes a shell assembly (520) having first and second mating shell portions (580, 590) to be disposed on opposites sides of the anchoring member and to be coupled together to anchor the electrode assembly within the anchoring member. Each of the first and second mating shell portions includes a center portion (595,600) and two lateral portions (596,597,602,603). The center portion fits over the anchoring member. The lateral portions of the first mating shell portion each have a prong member (605,608) and the lateral portions of the second mating shell portion each have an aperture (598,599). The prong members and apertures mate to form a locking arrangement.
