Mechanical Tissue Resuscitation (MTR) drainage after skull surgery

A Multi-center, Early Feasibility Study of Using the Mechanical Tissue Resuscitation™ (MTR®) Therapy System for Removal of Excess Fluid in Subjects Who Have Had a Portion of Their Skull Removed to Expose the Dura/Brain and Require Drainage for Fluid Removal.

Not applicable Interventional Renovo Concepts, Inc. · NCT06201429

This trial will try the Mechanical Tissue Resuscitation (MTR) device to drain excess fluid in adults 22–65 who have had part of their skull removed and need surgical drainage.

What this trial studies

This is a single-arm, multi-center early-feasibility trial testing the MTR device to externally drain excess fluid from craniotomy, craniectomy, or cranioplasty sites. Eligible adults (22–65) who would normally receive a Jackson Pratt or equivalent drain will be treated with MTR therapy for up to seven days. Enrollment is phased to include elective cases, patients with mild-to-moderate TBI (GCS ≥9), and patients with severe TBI (GCS 7–8), with a follow-up visit about one month after treatment. The study will collect safety, feasibility, and fluid-removal outcome data.

Who should consider this trial

Good fit: Adults aged 22–65 undergoing craniotomy, craniectomy, or cranioplasty who require placement of a Jackson Pratt (or equivalent) drain as part of their care are ideal candidates.

Not a fit: Patients outside the age range, those who are pregnant or lactating, those who do not have exposed dura or do not require a JP drain, or those meeting exclusionary acute severe TBI criteria may not receive benefit from this device.

Why it matters

Potential benefit: If successful, MTR could provide a short-term external drainage option to remove post-operative fluid and potentially reduce complications from fluid accumulation.

How similar studies have performed: Although external surgical drains are widely used, the MTR device represents a novel approach and has limited prior clinical experience in this exact setting.
