An implantable therapy lead is disclosed herein. The lead includes an elongated lead body having a suture sleeve. The suture sleeve is supported on the lead body and has each of an outer surface and an inner surface radially inward of the outer surface. The inner surface defines a lumen through which the elongated lead body extends. The suture sleeve further includes a structure projecting radially inward and/or outward from the inner surface. The suture sleeve is compressible from a first state into a second state by applying a constrictive force to the outer surface of the suture sleeve such that, when in the second state, the structure contacts the elongated lead body, at least in part, to resist movement of the elongated lead body relative to the suture sleeve.

Cardiac lead with suture sleeve

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.

Implantable therapy lead including bi-directional rotary blood ring seal

An implantable therapy lead is disclosed herein. In one embodiment, the therapy lead includes an elongated lead body and a suture sleeve. The elongated lead body has a proximal region and a distal region opposite the proximal region. The suture sleeve is supported on the lead body and has a proximal end, a distal end opposite the proximal end, an outer surface extending between the proximal end and distal end, and an inner surface radially inward of the outer surface and extending between the proximal end and distal end. The inner surface defines a lumen through which the elongated lead body extends. A helical structure helically extends about a longitudinal center axis of the lumen and along the inner surface.
