• The Grace Medical Eclipse Piston 467‑400 is a sterile, single-use ossicular prosthesis designed for stapedotomy or stapedectomy procedures to treat conductive hearing loss. It features a 0.5 mm diameter shaft and a 4.00 mm functional length, with a tip made from fluoroplastic and a shape memory zone constructed from nitinol. This combination enables gentle, 360° closure around the incus bone without manual crimping, promoting secure fixation while minimizing manipulation during surgery. The fluoroplastic tip reduces imaging artifacts, and the nitinol shape memory zone ensures consistent deployment and stable positioning once inserted.

• Grace Medical’s Eclipse design leverages the thermo-activated nitinol segment to ensure consistent deployment and stable positioning once inserted. The non-magnetic fluoroplastic component reduces imaging artifacts and helps maintain acoustic transmission. Catalog data positions the 467‑400 model among a series of Eclipse pistons available in varied lengths (3.75–6.00 mm) and diameters (shaft options in 0.4 mm, 0.5 mm, and 0.6 mm), offering surgeons flexibility in matching anatomical requirements.
