Abstract: A surgical simulation device is disclosed that allows a structural heart disease (SHD) team, including a surgeon and an imaging specialist to perform a simulated cardiac intervention procedure using a patient-specific model that replicates biomechanical and echogenic properties of a specific patient to be operated on. The surgical simulation device can include a station with a tank for receiving a patient-specific cartridge with the patient-specific model. The device can also include an esophageal access system in the station and a vascular access system that couples to an access port of the station.

Abstract: A multi-material three-dimensional printed portion of the heart configured to mimic an anatomical shape and a mechanical behavior of the portion of the heart, comprising: a first layer including a plurality of polygons, each said polygon having a plurality of vertices composed of a first material, each said polygon defining an interior portion filled with a second material different that the first material; and second and third layers sandwiching the first layer, the second and third layers composed of a third material; wherein the first material has a first Young’s modulus of between 1 and 2 Gpa; wherein the second and third materials each have a second Young’s modulus of between 0.5 and 5 Mpa.

Abstract: An echogenic organ replica and method of manufacture using an additive manufacturing system are provided. The echogenic organ replica includes at least one lower acoustic impedance material and a higher acoustic impedance material distributed within the at least one lower acoustic impedance material. The resulting echogenicity of the echogenic organ replica varies in three dimensions across each of the one or more locations to substantially replicate an echogenicity associated with corresponding locations of in vivo organ tissue.
