Abstract
Methods, devices and assemblies for anchoring implanted medical electrical leads employed in the stimulating and/or sensing of signals in tissue are disclosed. The devices include a lead anchoring clip having a central hub portion, an anchoring portion for coupling to tissue and a lead engagement mechanism that couples the clip to a medical electrical lead.
Claims5
A lead anchoring clip, comprising:
- a central hub portion having a circular shaped perimeter defined around a central axis;
- a hollow tubular-like structure centrally positioned within the circular shaped perimeter and having an internal diameter sized to engage around an external diameter of a medical electrical lead;
- and
- an anchoring portion including a first leg member extending around the central axis and outwardly from a first point of departure at the perimeter of the hub portion to a terminal tip thereof, and a second leg member extending around the central axis and outwardly from a second point of departure at the perimeter of the hub portion to a terminal tip thereof, the first and second leg members extending in the same direction, either clockwise or counterclockwise, partially circumferentially overlapping one another, and each of the first and second leg members forming an expanding diameter helical coil;
- wherein the tips of the first and second leg members are coplanar with one another, and each of the first and second leg members having a tapered distal end;
- and
- the first and second points of departure, from which the first and second leg members extend, respectively, are located opposite one another and offset along the central axis from the coplanar tips of the first and second leg members.
