Material 1: Polyurathane in Ventricular Assist Device
4.1 Basic characteristics of the material: e.g., molecular structure and connectivity, molecular weight range of the polymer for typical use, etc. as relevant to the device design and function (device is ventricular assist device)
4.2. Manufacturing process: how the material is synthesized and refined, stating clearly what the input raw materials are, what the processing steps are, including processing
conditions, and what the final product is, including the form in which the final product is
produced.
4.3. Mechanical, thermal and chemical properties of the material: Mention properties of the material relevant to the device’s manufacturing or function. Discuss the relationship between the molecular structure of the polymer and its mechanical, thermal, and chemical properties. How are these properties structure/processing
dependent?
4.4. Medical grade, suppliers and cost: Is there a medical grade for the particular material,
and if so, what factors make the material medical grade? Which companies are the
primary manufacturers and suppliers of the material? Please note that there is a
difference between a manufacturer and supplier. What is the unit cost of the material?
4.5. Suitability of the material for the device. Why was the particular material selected for
that particular component/device? Which properties of the material are relevant for its
use in the medical device/component?
Material 2: PTFE in Ventricular Assist Device
4.2. Manufacturing process: how the material is synthesized and refined, stating clearly what the input raw materials are, what the processing steps are, including processing
conditions, and what the final product is, including the form in which the final product is
produced.
4.4. Medical grade, suppliers and cost: Is there a medical grade for the particular material,
and if so, what factors make the material medical grade? Which companies are the
primary manufacturers and suppliers of the material? Please note that there is a difference between a manufacturer and supplier. What is the unit cost of the material?
4.5. Suitability of the material for the device. Why was the particular material selected for
that particular component/device? Which properties of the material are relevant for its use in the medical device/component?
(3 and half pages for polyurethane and 1 and half pages for PTFE)
