摘要： Embolic protection filters, filter membranes, and methods for making and using the same. An example embolic protection filter may include an elongate shaft having a proximal region and a distal region. A filter frame may be to the distal region. A filter membrane may be attached to the filter frame. The filter membrane may have a plurality of apertures formed therein. The filter membrane may include a polymer having a bulk portion and a surface portion. The surface portion may include a surface modification.

摘要： The disclosure pertains to a medical device deployment system comprising a restraint member which holds the embolic protection filter in a restrained, or partially collapsed, state for insertion into a lumen and transit to a desired deployment site. The restraint member comprises two or more portions which differ in their mechanical ability to resist the radial forces exerted by various portions of the medical device when it is in a restrained, or partially collapsed, state. The restraint member is maintained in a restraint configuration by an actuation member which engages portions of the restraint member lying on opposite sides of a generally axial gap until deployment of the medical device is desired. Withdrawal of the actuation member allows the restraint member to release the medical device which may then return to a deployed state. The invention also provides a method for assembling a medical device deployment system.
摘要翻译：本公开涉及一种医疗装置展开系统，其包括限制构件，该限制构件将栓塞保护过滤器保持在限制或部分折叠的状态，用于插入管腔并且转运到期望的部署位置。约束构件包括两个或更多个部分，其在机械能力方面不同，以抵抗由医疗装置的各部分施加的径向力在其处于受限制或部分塌缩状态时。约束构件通过致动构件保持在约束构造中，所述致动构件接合位于大致轴向间隙的相对侧上的限制构件的部分，直到需要部署医疗装置。致动构件的抽出允许约束构件释放医疗装置，然后可以返回到展开状态。本发明还提供了一种用于组装医疗装置展开系统的方法。
