SYSTEMS, CATHETERS, AND METHODS FOR TREATING ALONG THE CENTRAL NERVOUS SYSTEM

Systems, catheters, and methods for accessing and treating along the central nervous system are disclosed. An example method may control operation of a pump (104) of pump/filtration system (100) to facilitate removing cerebrospinal fluid from a patient, filtering the cerebrospinal fluid with a filter module (112) to remove waste product, and returning the filtered cerebrospinal fluid to the patient. Operation of the pump may be adjusted based on a value related to a measure sensed by a sensor (108) in communication with a lumen carrying cerebrospinal fluid through the filtration system. 公开了用于沿中枢神经系统而进入并治疗的系统、导管和方法。示范性方法可控制泵/过滤系统(100)的泵(104)的运行以便于从患者中取出脑脊液，用过滤器模块(112)对脑脊液进行过滤以去除废物，以及使经过滤脑脊液返回至患者。可基于与运送脑脊液经过过滤系统的内腔连通的传感器所感测的测量参数有关的值来调节泵的运行。
