Breast tissue models, materials, and methods
First Claim
1. A polysiloxane mixture for simulating human biological tissue, the mixture comprising:
- a silicone foam, wherein the silicone foam comprises a closed cell silicone foam; and
a silicone oil, wherein the silicone oil comprises a low molecular weight silicone oil;
the silicone foam and the silicone oil combined in a manner such that the resulting mixture has physical material properties simulating a natural human biological tissue.

Abstract
Devices, systems, and methods appropriate for use in medical training that include materials that better mimic natural human tissue are disclosed. In one aspect a polysiloxane mixture for simulating human biological tissue, especially human breast tissue, is disclosed. In another aspect, a method of manufacturing a biological tissue phantom is disclosed. In another aspect, a human breast tissue models are disclosed. In one instances, the human breast tissue model comprises a simulated breast tissue comprising a mixture of a silicone foam and a silicone oil and a simulated skin layer covering the simulated breast tissue, where the simulated breast tissue and the simulated skin layer are sized and shaped to mimic a natural human breast. In some instances, the human breast tissue model includes at least one simulated pathological structure that simulates such pathologies as a cyst, a medullary carcinoma, a ductal carcinoma, an infiltrating scirrhus carcinoma, a lobular carcinoma, and a fibroadenoma.
