A therapy lead has a distal header, a helix-shaft assembly, and a ring seal. The distal header has a cylindrical passage, and the helix-shaft assembly has a shaft and a helical anchor distally extending from the shaft. The shaft extends through the cylindrical passage. The ring seal circumferentially extends about the shaft and inside the cylindrical passage. The ring seal has a proximal face, a distal face, an outer circumferential surface, an inner circumferential surface, and a side wall. The distal face is opposite the proximal face. The outer circumferential surface extends between the proximal face and distal face. The inner circumferential surface is opposite the outer circumferential surface and extends between the proximal face and distal face. The inner circumferential surface defines a center hole of the ring seal that extends between the proximal face and distal face. A side wall extends in a continuous ring about the center hole and is defined by the proximal face, the distal face, the outer circumferential surface, and the inner circumferential surface. The side wall includes a radial cross section that is at least generally chevron-shaped.
