Multilayer self-healing membrane for septal closure of medical devices

Abstract

The membrane for the medical device includes a first portion having a first material and a second portion having a second material, the first material being an ionomer and the second material being at least one of a thermoplastic elastomer, a thermoplastic polyurethane, and a thermoplastic olefin. At least one of the first material and the second material can include a lubricant additive.

Claims

1. A first part containing the first material, A second part containing a second material, A membrane for medical devices, including The first material comprises an ionomer configured to have self-healing properties to minimize fragmentation when the needle passes through the membrane, The second material comprises at least one of thermoplastic elastomers, thermoplastic polyurethanes, and thermoplastic olefins. The aforementioned medical device is a patient connector, The patient connector is for connecting one component of a closed-system transport device or closed-system transport system to a patient's venous line. The membrane is a membrane for a medical device, characterized in that it is used in any component of the closed-system transport device or the closed-system transport system.
