Abstract
Official abstract text for this publication.
A fixation member of an electrode assembly for an implantable medical device includes a tissue engaging portion extending along a circular path, between a piercing distal tip thereof and a fixed end of the member. The circular path extends around a longitudinal axis of the assembly. A helical structure of the assembly, which includes an electrode surface formed thereon and a piercing distal tip, also extends around the longitudinal axis and is located within a perimeter of the circular path. The tissue engaging portion of the fixation member extends from the distal tip thereof in a direction along the circular path that is the same as that in which the helical structure extends from the distal tip thereof. The electrode assembly may include a pair of the fixation members, wherein each tissue engaging portion may extend approximately one half turn along the circular path.
First claim
Opening claim text (preview).
The invention claimed is: 1. An implantable medical device comprising a pulse generator, a power source, an hermetically sealed capsule that contains the pulse generator and the power source, and an electrode assembly, the electrode assembly comprising a longitudinal axis, a helical structure coupled to the capsule and extending distally from the capsule and around the longitudinal axis, a first electrode surface formed on the helical structure, and a second electrode surface elect…
