TISSIUM's Nerve Coaptation Device First-in-Human Clinical Trial

A Prospective, Multicenter, Single-arm Clinical Trial Evaluating Safety and Performance of TISSIUMTM Nerve Coaptation Device for the Repair of Digital Nerve Discontinuities Where Gap Closure Can be Achieved by Flexion of the Extremity.

The purpose of this study is to collect initial safety and device performance data of the TISSIUM's nerve coaptation device for the sutureless repair of digital nerve injuries of the hand in which there has been no substantial loss of nerve tissue. Additional clinical measures that assess device performance, use, and patient reported outcomes will be collected to guide future study design and potential device modifications.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Cumulative incidence of complications (CIC) related to the investigational device	CIC includes the occurrence of any of the following complications: Infection; Chronic pain (defined as pain lasting more than 3 months) not otherwise specified; Excessive inflammation as determined by the investigator; Device extrusion; Symptomatic neuroma formation; Impaired wound healing (examples are dehiscence, pain, skin irritation, keloid, scar hypertrophy); Allergic reaction to the constituent polymer of the investigational device; Serious Adverse Device Effect (SADEs)	through 12-months post-procedure

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Semmes-Weinstein monofilament (SWMF) for nerve functional recovery	Product performance will be assessed as functional nerve repair based on nerve functional recovery using Semmes-Weinstein monofilament (SWMF) at 6-months post-surgery	at 6 months post-procedure
