The patent application (Publication Number: US20240032937A1) describes an embolic device designed for placement in a body lumen. The device includes an elongated member that can change shape from a first configuration at room temperature to a three-dimensional structure at body temperature. This structure consists of segments that transition between martensitic and austenitic states based on temperature, with a softer segment between them. The device can form loops or multiple loops, with each segment playing a role in the loop formation.

Furthermore, the embolic device's elongated member comprises segments with different material properties, lengths, and temperature-dependent characteristics. The first and third segments change shape in response to body temperature, while the second segment remains martensitic throughout. The lengths of the segments are designed to create a specific configuration when the device transitions to its three-dimensional structure. Additionally, the device can form loops or multiple loops based on the configuration of the segments, providing versatility in its application within the body lumen. These features highlight the innovative design and functionality of the embolic device, offering potential benefits in medical procedures requiring precise and customizable embolization techniques.
