Abstract
A detection system can include a device, a circuit, and at least one indicator. The device can include polymer needle having a distal end and a proximal end. A needle lumen can be extended along a longitudinal axis of the polymer needle. The distal end can include an insertion tip. An elongate sleeve can include a first end and a second end. The polymer needle can be located within an inner bore of the elongate sleeve. The insertion tip of the polymer needle can be disposed at a distance from the elongate sleeve. A first electrode can be coupled to the device and a second electrode can be electrically isolated from the first electrode. The circuit can be configured to provide a signal based on an electrical characteristic between the first electrode and the second electrode. At least one indicator can be communicatively coupled to the circuit and configured to provide an output based on the signal.
