V-Wave Interatrial Shunt Patent Granted for Adjustable In Vivo Devices
Summary
USPTO granted Patent US12599756B2 to V-Wave Ltd. on April 14, 2026. The patent covers interatrial shunt devices for placement at a patient's atrial septum with dimensions that can be reduced and increased in vivo. The device includes first and second regions coupled by a malleable neck region, using shape-memory materials where the regions are superelastic at body temperature while the flow area through the neck is adjustable in vivo.
What changed
USPTO granted Patent US12599756B2 to V-Wave Ltd. for an interatrial shunt device with dimensions that can be reduced and increased in vivo. The patent covers a body with first and second regions connected by a neck region, using shape-memory material where the regions exhibit superelasticity at body temperature while the neck region is malleable, allowing in vivo adjustment of the flow area through the passageway.
Medical device manufacturers developing cardiac implants or interatrial shunt devices should monitor this patent for potential licensing requirements or design-around considerations. Competitors in the heart failure device space may need to evaluate whether their products fall within the scope of the 14 claims granted.

Abstract
Devices are provided with an internal dimension that can be reduced and increased in vivo. In one example, an interatrial shunt for placement at an atrial septum of a patient's heart includes a body. The body includes first and second regions coupled in fluid communication by a neck region. The body includes a shape-memory material. The body defines a passageway through the neck region for blood to flow between a first atrium and a second atrium. The first and second regions are superelastic at body temperature, and the neck region is malleable at body temperature. A flow area of the passageway through the neck region may be adjusted in vivo.
