    摘要: An endoscope apparatus and method of operating the same. The endoscope apparatus comprises an endoscope portion and a control and display unit. The endoscope portion preferably comprises: (i) a sensor disposed at a distal end of the endoscope portion and providing endoscope data; (ii) one or more electronically controlled actuators (e.g., electroactive polymer actuators) controlling the operation of the endoscope portion based on received control signals; (iii) a first wireless transceiver coupled to the sensor and the one or more electronically controlled actuators, transmitting received endoscope data from the sensor and forwarding received control signals to the one or more electronically controlled actuators; and (iv) a portable power source (e.g., a battery) coupled to the sensor, the first wireless transceiver, and the one or more electronically controller actuators. The control and display unit preferably comprises: (i) a second wireless transceiver coupled via a wireless link to the first transceiver in the endoscope portion and receiving endoscope data from the first transceiver and transmitting control signals to the first transceiver; (ii) a control portion coupled to the second wireless transceiver and sending control signals to the one or more actuators in the endoscope portion via the first and second wireless transceivers; and (iii) a display portion that displays information received from the sensor via the first and second wireless transceivers. Another aspect of the present invention is directed to a method for providing single-use endoscopes to one or more hospitals.

    摘要: A medical device, for example, an endoscope or catheter, includes local drug delivery capabilities for selectively delivering at least one drug in vivo. The local drug delivery may occur as the medical device is advanced through tortuous passageways of the patient's body or may occur after the medical device has reached its targeted destination. The medical device includes a drug agent, for example, carried in or on a hydrophilic or hydrogel coating disposed on the outside thereof. When the hydrogel or drug agent receives an appropriate signal, e.g., solution containing a triggering agent or triggering condition, e.g., heat or light, the hydrogel contracts or expands to squeeze out the drug from hydrogel. If electric current is provided as the signal, and the drug agent is charged, the drug agent is released by electrophoretic forces.
