Radiation resistant silicone formulations and medical devices formed of same
View Patent ↗The disclosure is directed to a sterilized medical device including a non-polymerized blend including a silicone matrix material and a radiation resistant component.
1. A method of forming a medical device, the method comprising:
preparing a mixture of polyalkylsiloxane precursors and a radiation resistant component to a loading about 0.1 wt % to about 20 wt % of the resistant component based on the weight of the polyalkylsiloxane precursors;
filling a mold with the mixture; and
curing the polyalkylsiloxane precursors to form the medical device.
2. The method of claim 1 , wherein the radiation resistant component remains non-polymerized with the polyalkylsiloxane precursors after curing.
3. The method of claim 1 , wherein the radiation resistant component is fluorosilicone oil or phenylsilicone oil.
4. The method of claim 1 , further comprising forming an opening defined by two separably contacting surfaces in the medical device.
5. The method of claim 1 , further comprising sterilizing the medical device.
