A Study to Expand the Use of Symani® Surgical System for Peripheral Nerve Repair

REGEN: A Prospective, Randomized, Open Label Study to Expand the Use of Symani® Surgical System for Peripheral Nerve Repair

Sponsor

MMI (Medical Microinstruments, Inc.)

Enrollment

100 participants

Start Date

Dec 18, 2025

Study Type

INTERVENTIONAL

Conditions

Nerve Injury Peripheral Nerve Injuries

Summary

The objective of this study is to evaluate the Symani System's safety and effectiveness for microsurgical nerve coaptation, following nerve injuries to the hand. This study will include participants with traumatic sensory nerve lesions of a finger nerve distal to the carpal tunnel who are treated with nerve suturing. The primary effectiveness endpoint is the two-point discrimination (2PD) test, at 6-months post index procedure. The primary safety endpoint is the intraoperative serious adverse event rate.

Eligibility

Min Age: 18 YearsMax Age: 70 Years

Complete loss of a nerve-specific receptive field of the finger
Patient with a clinical indication for a microsurgical nerve coaptation in nerve injury that can be repaired by end-to-end suturing
Patient with traumatic transection of one or more digit nerves distal to the carpal tunnel with sensory autonomous innervation areas on the finger or thumb tips
Investigator considers candidate acceptable for either conventional epineural suturing or robotic-assisted epineural suturing
The injury was treated within 10 days
Individuals will be included in the study if the following criteria are met intraoperatively:

Interventions

DEVICESymani® Surgical System

Robotic-assisted surgery consists of participants who undergo nerve coaptation with the Symani Surgical System, according to the Instruction for Use (IFU). In order for the surgery to be considered a robotic assisted surgery, the participants must be randomized to the RAS group which will include: * Participants where all nerve coaptations were performed entirely with Symani. * Participants who underwent a hybrid procedure, where a coaptation was commenced using Symani but a switch to manual suturing occurred during the procedure

PROCEDUREManual Surgery

Manual surgery consists of participants who undergo nerve coaptation through manual techniques by a surgeon using handheld instruments without robotic assistance. In order for the surgery to be considered a manual surgery, the participants must be randomized to the MS group which will include: * Participants where all nerve coaptations were performed entirely manually. * Participants who underwent a hybrid procedure, where a coaptation was commenced using manual suturing but a switch to Symani occurred during the procedure.
