Medical grade Silicones for manufacturing catheters

Silicone elastomers have been used for decades to manufacture catheters, which can be inserted into the body to remove or deliver fluids. The urethral catheter, which can be made entirely out of various medical grade silicones, is an indwelling catheter that resides in the bladder and used to drain urine from the bladder to external bag. A tiny balloon at the end of the catheter is inflated with water to prevent the tube from sliding out of the body. Veinous catheters are another type catheter which are used to delivery medication or fluids into the body.

Materials used in the manufacturing of catheters need to be biocompatible, hypoallergenic and sterilizable  in order to be well tolerated by the patient. They should also allow for efficient manufacturing as catheters are typically single use devices. Elkem Silicones provides a complete product portfolio and wide range of Silbione medical grade silicones to answer the needs of catheter manufacturers and increase the quality of life for the patient.
