    摘要: A method according to an embodiment of the invention includes inserting an endoscope at least partially into a body lumen. At least a portion of the body lumen is illuminated at a first wavelength. The portion of the body lumen is illuminated at a second wavelength different than the first wavelength. A characteristic of an area of interest when the portion of the body lumen is illuminated at the first wavelength is compared with the characteristic of the area of interest when the portion of the body lumen is illuminated at the second wavelength. A medical device or treatment parameter is selected to treat the area of interest based on the comparing. In some embodiments, the body lumen is a ureter. In such an embodiment, a composition of a kidney stone within the ureter can be identified.

    摘要: A system and related methods for maintaining the patentcy of the ureter comprising a pusher tube having a pusher tube lumen and an inflate lumen disposed within a wall of the pusher tube and a urinary stent having a proximal and distal portions with an elongated body portion therebetween configured to fit the ureter of the patient and defining a lumen. The system further includes an end-effector that may comprise an inflatable balloon positioned at the proximal portion of the urinary stent for retaining the proximal portion in the urinary bladder. At the distal portion, a retention end-piece is positioned for retaining the distal portion of the stent in the renal pelvis. The end-effector and the retention end-piece of the stent maintain the elongated body portion in situ. The end-effector may also include an inflatable balloon and may contain pharmaceutical or biologic agents for controlled release into the bladder.

    摘要: An ambulatory urodynamic data gathering system includes one or more sensors disposed in the gastrointestinal tract, a sensor disposed in the bladder, a sensor disposed at the entrance to the urethra, and a data recorder worn by the patient that is disposed around the patient's waist. The sensors transmit data to the recorder unit, which stores the received data for subsequent analysis. The recorder unit also activates the various sensors as necessary to obtain information at certain predetermined intervals to limit battery usage. The recorder unit can also interrogate the various sensors to obtain the information. In one exemplary embodiment, the ambulatory urodynamic data gathering system includes a method and device for simultaneously recording radio transmitted pressure measurements from a swallowed self-contained capsule (pressure monitor, signal processing, transmitter, power source or coupling antenna), and a self-contained unit placed in the bladder, for the purpose of deriving urodynamic information. The system of the present invention enables collection of pressure wave information above the waist of the patient so that a doctor can subsequently analyze the data to determine where the problem may lie.

    摘要: A method according to an embodiment of the invention includes receiving a first optical image from an endoscope having a plurality of imaging fibers. A spatial frequency is identified that is associated with the plurality of imaging fibers. A second optical image is received from the endoscope. The spatial frequency is filtered from the second optical image. A method according to another embodiment includes producing an optical image of at least a portion of a body lumen using a fiberscope. The optical image is transmitted to a video camera coupled to the fiberscope. A honeycomb pattern associated with a fiber bundle of the fiberscope is removed from the optical image. In some embodiments, the honeycomb pattern can be removed in substantially real time. In some embodiments, prior to producing the optical image, a calibration cap is coupled to the fiberscope and used in a calibration process.
