EXPANDABLE INDUCTOR SHEATH FOR MEDICAL DEVICES

An expandable introducer sheath and associated laser cutting frame for inserting a medical device into a blood vessel. In some examples, the expandable sheath may have a frame including a plurality of radially expanding bands and a plurality of connecting bridges for connecting adjacent radially expanding bands. The radially expanding band is configured to accommodate radial expansion, and the plurality of connecting bridges is configured to be longitudinally expandable and configured to impart strength to the column when a medical device (e.g., an intracardiac heart pump) passes through the sheath, such as during insertion or removal of the medical device. 用于将医疗设备插入血管的可扩展导引器护套和相关激光切割框架。在一些实例中，可扩展护套可以具有框架，该框架包括多个径向扩展带和多个用于连接相邻径向扩展带的连接桥。径向扩展带被配置为容纳径向扩展，以及多个连接桥被配置为可纵向扩展，并被配置为在医疗设备(例如，心内心脏泵)穿过护套时，例如在插入或移除医疗设备期间，赋予柱体强度。
