New Materials for an Implantable Blood Pump

旋转血泵处于心脏辅助技术的前沿。VentrAssist开发了一种具有流体动力悬浮叶轮的创新型旋转血泵。先进的表面修饰将使该装置能够由聚合物制造；这将使该设备更轻，与人体更兼容，生产成本更低。表面处理和涂层将使用离子注入，以赋予所需的尺寸稳定性，不渗透性和耐磨性。在对改性材料进行复杂的实验后，最佳候选材料将用于原型设备，以最终选择新设备的最佳材料。

Rotary blood pumps are at the leading edge of heart assist technology. VentrAssist has developed an innovative rotary blood pump with a hydro-dynamically suspended impeller. Advanced surface modifications will enable the device to be fabricated from polymers; this will make the device light, more compatible with the human body and less costly to produce. Surface treatments and coatings will be applied using ion implantation, to impart the required dimensional stability, impermeability and wear resistance. Following sophisticated experiments of modified materials, the best candidates will be used in prototype devices, for final selection of the optimal materials for the new device.
