An organ model comprises a polymer body formed from one or more selectively deposited substructures of a printable polymer-based ink composition, wherein the one or more selectively deposited substructures form a printed geometrical structure that corresponds to at least a portion of an anatomical structure of an organ, wherein a formulation of the printable polymer-based ink is selected such that the printed geometrical body has one or more material properties that match or substantially match one or more corresponding tissue material properties of an organ tissue, and an electronic device integrated onto a surface or into a structure of the printed geometrical structure.

A system for assessing performance of a procedure comprises a tissue model or a tool comprising assessment indicators applied thereto, one or more image-capturing devices for capturing one or more assessment images of the assessment indicators while or after a user performs the medical procedure, and a processor configured to analyze the assessment indicators in the one or more assessment images and provide feedback to the user. A system can also comprise a tissue model, one or more image-capturing devices each configured to capture one or more images of the tissue model, and a processor configured to analyze the one or more images from the one or more image-capturing devices to determine a deformation of the tissue model and determine a force exerted on the tissue model based on the determined deformation of the tissue model.

Systems and methods for analyzing surgical techniques

A method of making a tissue model comprises determining one or more material properties of a tissue, wherein the one or more material properties include at least one of mechanical properties, electroconductive properties, optical properties, thermoconductive properties, chemical properties, and anisotropic properties, creating an anatomical structure of the tissue, selecting an artificial tissue material having one or more material properties that substantially correspond to the one or more material properties of the tissue, and coupling the artificial tissue material to the anatomical structure.
