Questions

AI-generated answers, 28 Sep 2026

Written by a language model from registry data. Not verified by deviCERTS or the manufacturer. The registry data above is the record.

  • What clinical situation is the Residual Limb Lengthening System intended for?

    It is intended for orthopedic procedures that require lengthening of a residual femoral limb. The telescoping intramedullary nail is implanted in the bone and can be incrementally extended, allowing surgeons to restore length in cases such as post‑amputation reconstruction or congenital shortening.

  • How is the system supplied and what components are included?

    The system is supplied sterile as a complete kit. It includes the telescoping intramedullary nail, the necessary locking screws, a set of surgical instruments for implantation, and an external remote controller that enables the clinician to control the distraction process precisely.

  • Is the device single‑use or can it be reused?

    The kit is provided sterile for a single surgical implantation. While the nail remains in the patient for the duration of the lengthening course, the packaging and instruments are intended for one‑time use to maintain sterility and ensure consistent performance.

  • What regulatory pathway did the device follow for market entry?

    The Residual Limb Lengthening System received FDA 510(k) clearance (K141739) under the traditional clearance type, indicating it was found substantially equivalent to a legally marketed predicate device in the orthopedic category.
