摘要:
A system and method for providing programmable brake control in a fly-by-wire medical instrument system are provided. In one embodiment, the invention provides a brake control system that includes a brake control algorithm that provides temporal and spatial control of the motion of a medical instrument.
摘要:
An ultrasonic imaging catheter apparatus and a method of using the same to scan the inner wall of a body lumen. The ultrasonic imaging catheter apparatus comprises: (a) a flexible elongate element adapted for insertion into a body lumen, the elongate element having distal and proximal ends; (b) an ultrasonic transducer generating and detecting ultrasonic energy disposed proximate the distal end of the elongate element; (c) a reflective member disposed proximate the ultrasonic transducer and optionally rotatable with respect to an axis of the body lumen, wherein the reflective member is adapted to reflect (i) ultrasonic energy generated by the ultrasonic transducer to a wall of the body lumen and (ii) ultrasonic energy reflected by the wall back to the transducer; and (d) an actuator, for example, an electroactive polymer actuator, adapted to change the angle of incidence of the ultrasonic energy relative to the reflective member.
摘要:
A system, device and method for serializing and authorizing a single use imaging device are provided. In one embodiment, the invention provides a single use imaging device comprising a memory having a stored code that includes a unique serial identifier. In another embodiment, the invention provides a system for authorizing a single use imaging device comprising a single use imaging device with an image of a verification object that includes a serial identifier uniquely associated with the device, a control unit capable of electronically receiving the verification object image, a decoder capable of extracting a serial identifier from the verification object image, a database of authorized serial identifiers, and means for determining if the single use imaging device is authorized.
摘要:
The present invention provides an exterior counterpulsation (ECP) system that includes a garment for being worn on the exterior of a patient's body. The garment includes electroactive polymer (EAP) actuators connected thereto. In one embodiment, the EAP actuators are woven into the garment. In another embodiment, they are mounted to the garment surface.

摘要:
The system 10 includes an endoscopic probe 20 and an expired air sampling device 24 functionally connected to a control console 28. In use, the endoscopic probe 20 is routed through a body lumen of a patient to, for example, visualize a selected region of a patient's body. As the endoscopic probe 20 is routed through the body lumens, the expired air sampling device 24 collects expired air from the patient, generates signals indicative of patient respiratory status, and outputs the generated signals to the control console 28. The control console 28 processes the signals and monitors the respiratory status of the patient. If the respiratory status of the patient changes based on the processed signals of the expired air sampling device 24, the control console 28 may output an audible or visual alert signal.
摘要:
An endoscope is provided which comprises an elongated body adapted for insertion into a body lumen, and a plurality of electrically controlled actuators associated with the body which are controllable to impart an orientation to the body that is complimentary to the natural orientation of the lumen into which the endoscope is inserted.
摘要:
The invention enhances ultrasonic visualization of a medical device by coating the surface of the medical device with a contrast agent preferably comprising microbubbles. The contrast agent responds to incident ultrasound waves to generate vibrations at a harmonic frequency (i.e., a harmonic of the frequency of the incident wave), non-harmonic vibrations or a combination of harmonic and non-harmonic vibrations. In one embodiment, the microbubbles are coated on the medical device using an intermediate adhesion layer that adheres to the surface of the device. In a second embodiment, the microbubbles are incorporated in the adhesion layer.
