LivaNova Roller Pump, Adjustable Rollers, Perfusion System
Summary
LivaNova Deutschland GmbH has filed USPTO patent application US20260110295A1 for a roller pump with electronically adjustable roller positions for use in extracorporeal perfusion systems. The invention includes a rotor with first and second roller arms, each having rollers rotatably coupled, a raceway disposed around the rotor, and an electronic actuator configured to change the radial position of the rollers. An extracorporeal perfusion system incorporating this pump would include a fluid reservoir, oxygenator, and flexible tubing disposed within the raceway, with the motor configured to rotate the rotor to cause fluid flow within the tubing.
“The actuator may be couplable to the motor such that the motor is capable of rotating the rotor and changing the radial position of the first and second rollers.”
About this source
USPTO classification A61M covers devices that introduce or withdraw fluids from the body: infusion pumps, catheters, syringes, inhalers, wound drainage, dialysis equipment, and fluid-handling microfluidics. Every newly published application in A61M lands in this feed, around 205 a month. Applications publish 18 months after filing. Watch this if you compete in infusion therapy or drug delivery, file freedom-to-operate analyses for medical device startups, scout acquisition targets in cardiovascular or respiratory devices, or track hospital R&D arms that are quietly patenting clinical innovations.
What changed
LivaNova Deutschland GmbH has filed a patent application with the USPTO for a roller pump designed for use with perfusion systems. The pump features a rotor with two roller arms, each with rollers that can be electronically adjusted in their radial position relative to the rotor via an electronic actuator disposed on the rotor. The actuator may be couplable to the motor, allowing the motor to simultaneously rotate the rotor and change the radial position of the rollers. An extracorporeal perfusion system incorporating this pump includes a fluid reservoir, oxygenator, and flexible tubing disposed within the raceway.
Medical device manufacturers developing perfusion systems, cardiac surgery devices, or roller pump technology should note this filing as it may indicate LivaNova's direction in adjustable-flow pumping systems. Competitors in the ECMO or cardiopulmonary bypass device space should review their own technologies for potential intellectual property overlap.

Abstract
A roller pump includes a roller pump rotor including a first roller arm having a first roller rotatably coupled thereto and a second roller arm having a second roller rotatably coupled thereto, a raceway disposed around the rotor, a pump motor configured to rotate the rotor relative to the raceway, and an electronic actuator disposed on the rotor, wherein the actuator is configured to change a radial position of the first and second rollers. The actuator may be couplable to the motor such that the motor is capable of rotating the rotor and changing the radial position of the first and second rollers. An extracorporeal perfusion system includes a fluid reservoir, an oxygenator, flexible tubing coupling the reservoir to the oxygenator, and the roller pump, wherein the flexible tubing is disposed within the raceway. The motor is configured to rotate the rotor to cause fluid to flow within the tubing.
