EndoRotor® Features

Determine your resection limits – instead of your instruments imposing their limitations on you. The EndoRotor® allows you to simultaneously dissect, resect and collect tissue. This 3-in-1 endoscopic interventional tool provides features that complement today’s GI toolkit.
  • Endoluminal preservation – EndoRotor enables resection of scarred lesions without removing muscle, maintaining lumen patency and avoiding surgery
  • Non-thermal mechanical resection of persistent adenoma
  • Used clinically to facilitate EMR lateral margins and tissue bridges
  • Potential to replace multiple instruments and eliminate instrument exchange time

FAQs

How does the EndoRotor work? . . .

The EndoRotor is an endoluminal surgical tool for debriding tissue not amenable to conventional instrument resection. Tissue is aspirated into the catheter and cut simultaneously. Aspirated tissue is available for histopathologic analysis.

How does the EndoRotor help me? What are the advantages over how I perform resection today? . . .

The incidence of incomplete resection during EMR is well documented throughout clinical literature. Because of combined suction and rotation, the instrument allows the user to remove residual tissue without the need to lift, including post-EMR scarred lesions and lateral margins in primary resections. The EndoRotor® is a versatile tool that is not limited by tissue morphology.

What about pathological specimens? . . .

The EndoRotor has FDA clearance for use by gastroenterologists to resect and remove residual tissue from the peripheral margins following Endoscopic Mucosal Resection (EMR). Procedures completed by physicians globally routinely involve specimens evaluated by pathologists without challenge.

What about margins? . . .

In a recent series (Emmanuel et al.) following wide field EMR, physicians used magnification chromoendoscopy in to confirm negative margins. Using the EndoRotor to resect the margins, pathology revealed a 13% residual tissue in the margins and base previously shown as negative by magnification chromoendoscopy. There were no recurrences at follow up. 1

What about perforation or bleeding? . . .

The EndoRotor has been in use globally since 2016. Prophylactic epinephrine helps to mitigate bleeding risk. Perforation risk is within the standards of reported literature.

Where can I use the device? . . .

The EndoRotor is cleared for use by a trained gastroenterologist to resect and remove residual tissue, not intended for biopsy, of the gastrointestinal (GI) system including post-endoscopic mucosal resection (EMR) tissue persistence with a scarred base and residual tissue from the peripheral margins following EMR.

Are there any studies being done? . . .

For investigational use for these indications: The EndoRotor is currently under investigation for the removal of walled-off pancreatic necrosis during direct endoscopic necrosectomy and for refractory Barrett’s mucosa. View Ongoing Clinical Studies | View Completed Clinical Trials
