摘要： Balloon cannula systems may be used for accessing and visualizing the spine and related methods of treatment, including a forward-looking balloon system for creating a working space and the balloon system having atraumatic dissection capability to allow visualization in spine. The devices and methods described may be used, for example, to perform annulus repair, herniated disc excision, and denervation of neurological tissue; to dispense pharmacological agents and/or cell or tissue therapy agents; to diagnose disc degeneration and bony degeneration, spinal stenosis, and nucleus decompression, and to perform disc augmentation.

摘要： A disposable seal assembly for use with a reusable cannula preferably includes a flapper valve fluid seal and at least one instrument seal. The instrument seal has a sacrificial flange and a sealing flange that protrude from an inner baffle connected to the assembly's main body by a flexible outer baffle, and at least one elastomeric rib extending between the inner baffle and the body to prevent inversion of the inner baffle. Preferably, a surface of the sacrificial flange is configured to prevent the flanges from sticking together during use. An adaptor, tethered to the assembly's main body, has a central channel with an hourglass profile, a concave distal flange, distal bumpers for preventing the adaptor from translating too far into the main body, and a grip portion shaped to allow a user conveniently to separate the adaptor from the main body. Other aspects include systems with a reusable cannula, and methods for using such systems.

摘要翻译： 与可重复使用的套管一起使用的一次性密封组件优选地包括挡板阀流体密封件和至少一个仪器密封件。 仪器密封件具有牺牲凸缘和密封凸缘，其从通过柔性外挡板连接到组件主体的内挡板突出，并且至少一个弹性肋在内挡板和主体之间延伸以防止内挡板反转 。 优选地，牺牲凸缘的表面构造成防止凸缘在使用期间粘在一起。 连接到组件主体的适配器具有一个具有沙漏轮廓的中心通道，一个凹形的远端凸缘，用于防止适配器平移到主体太远的远侧缓冲器，以及一个形状适于使用户方便地 将适配器与主体分开。 其他方面包括具有可重复使用的套管的系统以及使用这种系统的方法。
