US 9,872,976 B2 · Assembly and method for stabilizing a percutaneous cable

Abstract

A percutaneous cable is attached to a mechanical cardiac pump and is passed through the skin. Sutures can be used to stabilize the cable against movement to prevent disturbing tissue surrounding cable and thereby reduce the incidence of infection. A funnel-shaped tubular device can be used where the cable exits the skin to allow the cable to flex below or near the skin surface as may be desired to accommodate physical activity of a patient. An anchor can be attached to the cable and implanted below the skin surface to stabilize the cable against movement. The anchor can include any one or a combination of a flat mesh material, a bundle of ultrafine filaments, and a barbed filament.

Dependent claims

An assembly comprising:

a percutaneous cable including a power line for powering a mechanical cardiac pump and a communication line for data communication with the mechanical cardiac pump;
an anchor attached to the percutaneous cable, the anchor comprising a mesh in a collapsed state, the mesh configured to engage biological tissue by tissue growth in the mesh, there being a slit formed through an outer edge of the mesh;
a split ring connecting the anchor to the percutaneous cable, the split ring configured to slide axially along the percutaneous cable and to clamp onto or be crimped onto a selected position on the percutaneous cable;
and
a wrapper fixedly attached to and disposed around the anchor to keep the anchor in the collapsed state.
