Oklahoma Patent of the Month – February 2021

Devices like blood pumps and bypass valves need access to hollow cavities of organs. Usually this access is facilitated by a port or some sort of access point. The organ tissue is more malleable than these devices, however, and can lead to bodily fluid leakage at the connection point. They can also trigger foreign body immune responses and lead to further complications. VADovations, Inc. has designed a new tissue interface to reduce the risks imposed from these devices.

The device is designed to allow fluids to pass through and support the external device (e.g. bypass valve). The device acts as an intermediary between the organ and the required device so that the organ tissue has contact with the interface device instead of the required device. Shaped like a hollow cylinder, the device would also include a flat extension to sit flush against the external organ tissue and hold in place. The other end would include deployment extensions which are first pulled towards the core of the cylinder to slide through a hole in the organ. Once placed properly, the deployment extensions (which are now inside the organ) flare out to rest against the organ’s internal tissue. The interior of the core is smooth to prevent biological material from sticking and growing there, while the sleeve surrounding the core is made of fibrous materials such as bovine pericardium. The design and material prevent a foreign body immune response and ensure the organ does not experience adverse effects.
