Tandem's Wearable Insulin Delivery Pumps Utilize TOPAS® Cyclic Olefin Copolymer (COC)

Precision Molded Cartridge Parts Deliver Drug Compatibility, High Purity, and Dimensional Control

FLORENCE, Ky., April 26, 2018 – Wearable insulin delivery pumps from Tandem Diabetes Care Inc., a San Diego, Calif.-based medical device manufacturer of the only touchscreen insulin pumps in the U.S., use disposable cartridges molded of TOPAS® 8007S-04 cyclic olefin copolymer (COC) from Polyplastics USA.

The simple-to-use t:slim X2 Insulin Pump is the smallest pump available and the only one capable of remote feature updates. It is the first CGM-enabled pump approved to let users make treatment decisions without pricking their finger. The t:flex® Insulin Pump has the largest insulin capacity available - up to 480 units, providing up to three days of insulin delivery with fewer interruptions for cartridge changes compared to other pumps.

The pumps carry precision-molded disposable cartridges which consist of several parts molded of TOPAS 8007S-04. The components are manufactured under strict performance qualifications including highly challenging tolerance levels and multi-cavity tooling. They are produced in complex geometries and tight tolerances of less than 0.001 in. (0.025 mm).

 The medical grade material was selected over competitive thermoplastics due to its purity, drug compatibility, biocompatibility, and dimensional stability. As a leading healthcare plastic, the drug-contact material delivers consistent, reproducible performance and facilitates miniaturization of drug delivery systems. TOPAS COC can also be molded with zero draft for maximum precision of drug delivery.

Plastikos Inc.a leading custom injection molder, and its sister mold making company, Micro Mold, worked closely with Tandem to develop the molds and manufacture the cartridge parts. Plastikos is one of the leading medical molders of precision COC components for drug delivery devices, with shipments of millions of parts during the past year.

Unlike other engineering thermoplastics or glass, TOPAS COC offers a non-ionic, minimally reactive surface. This non-polar substrate does not promote adsorption, denaturation, aggregation, or precipitation. With very low leachables and extractables, glass-clear TOPAS medical polymer preserves long-term drug purity, enabling better performance and patient safety.
