V-Wave Interatrial Shunt Patent US12599756B2 Granted April 14
Summary
USPTO granted patent US12599756B2 to V-Wave Ltd. covering interatrial shunt devices with in vivo adjustable dimensions. The patent includes 14 claims for a body with shape-memory material defining a passageway through a neck region between atria, where first and second regions are superelastic at body temperature and the neck region is malleable for flow adjustment.
What changed
USPTO granted patent US12599756B2 to V-Wave Ltd. for an interatrial shunt device designed for placement at a patient's atrial septum. The device features a body with first and second regions connected by a neck region, constructed from shape-memory material where the outer regions remain superelastic at body temperature while the neck region is malleable, allowing in vivo adjustment of the blood flow passageway.
For medical device manufacturers developing cardiovascular implants, this patent establishes intellectual property protection around adjustable-flow interatrial shunt technology. Competitors entering this space should evaluate whether their designs may infringe V-Wave's claims or consider designing around the patented configurations.

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.
