Abstract
Tissue access devices and methods of using the same are disclosed. The devices can have a sensor configured to occlude a flow path by deflecting a membrane into the flow path when the devices become dislodged from tissue. The sensor can be configured to partially or fully occlude the flow path. The sensor can have a spring. The spring can be biased to move the sensor from a sensor first configuration to a sensor second configuration when a force applied by the sensor first surface against a non-sensor surface changes from a first force to a second force less than the first force. The membrane can be deflected into the flow path when the sensor is in the sensor second configuration.
