Abstract
A prosthetic implant, such as a tissue expander, includes a silicone shell having an anterior wall and a posterior wall, and a needle stop patch secured over an inner surface of the posterior wall of the silicone shell. The needle stop patch has two or more layers of a textile material that are stacked atop one another. The textile material is flexible and includes woven threads or fiber. A bonding material bonds together the two or more layers of the textile material that are stacked atop one another. The outer edges of the respective layers are feathered for minimizing step effects between adjacent ones of the layers. A self-sealing membrane covers the anterior wall of the silicone shell. The dernier level of the textile layers increases between top and bottom layers for progressively increasing resistance tom a needle passing through the needle stop patch.
