摘要： A shaft for a medical device includes an outer sheath and a flexible spiral wrap therein. The flexibility of the spiral wrap is modified by changing the width of the wraps of a spiral, the thickness of the wraps of a spiral, or the gap spacing of the spiral. The spacing between wraps is maintained by attaching the spiral wrap to the cover sheath that surrounds the spiral wrap at two or more locations.

摘要： The present invention is directed to a drug delivery pump apparatus, which comprises: (a) an expandable and contractible enclosure having an interior volume that defines a medication reservoir; (b) one or more electroactive polymer actuators; (c) a medication outlet port providing fluid communication between the interior volume of the contractible and expandable enclosure and an exterior of the delivery pump apparatus; and (d) a control unit electrically coupled to the one or more actuators and sending control signals to the same. The one or more electroactive polymer actuators act to reduce the interior volume of the contractible and expandable enclosure based upon the received control signals. The present invention is also directed to a method of delivering a liquid therapeutic agent to a patient. The method comprises: (a) providing the above infusion pump apparatus; (b) placing the outlet port of the infusion pump apparatus in fluid communication with a patient; and (c) sending the control signals to the one or more actuators to reduce the internal volume of the contractible and expandable enclosure, thereby forcing a portion of the liquid therapeutic agent within the medication reservoir through the outlet port and into the patient

摘要： A steerable endoscopic sheath has a proximal end, a distal end and a working channel lumen disposed therein. A plurality of solid state light emitting devices such as light emitting diodes are positioned near the distal end of the sheath and are selectively energized to illuminate internal body tissues. An imaging device such as a photo diode or CCD array creates an image from light reflected from the tissue. The distal tip of the endoscopic sheath is selectively moveable with a deflection device that is insertable into the sheath. The deflection device includes a tip deflection mechanism that allows a user to move the tip of the deflection device. With the deflection device inserted in the sheath, movement of the distal tip causes a corresponding movement in the distal tip of the sheath. The distal tip of the sheath has a shape retaining mechanism that allows it to retain the shape imparted by the deflection device once the deflection device is removed from the sheath.

摘要： A catheter (20) for diagnosing and performing an interventional procedure on tissue has an elongated catheter shaft, and optical fibers (20, 26), extending through the catheter shaft, for transmitting light to tissue located at a distal end of the catheter and conveying light back from the tissue for analysis by a spectroscopic diagnosis system (42) to determine whether an interventional procedure should be performed on the tissue. An interventional device (52) is located at the distal end of the catheter for engaging tissue diagnosed by the spectroscopic diagnosis system in order to perform the interventional procedure on the tissue. An assembly for imaging and performing an interventional procedure on tissue has an endoscope in combination with an endoscopically insertable catheter having an ultrasound imaging device for imaging a tissue structure located at a distal end of the endoscope so as to enable the depth of penetration of the tissue structure to be displayed, and an endoscopically insertable interventional device for engaging the tissue structure imaged by the ultrasound imaging device.

摘要： An endoscopic imaging system includes an endoscope with a beam deflecting mechanism at or adjacent its distal end for directing a beam of illumination light over an area of interest. Reflected light is gathered by one or more lenses and supplied to a light sensor and an image processor/computer that produces an image of the tissue. In one embodiment, the beam deflecting mechanism comprises a pair of mirrors that are oscillated such that light is scanned in a raster pattern over the area of interest.

摘要： The present invention is an integrated and automated irrigation and aspiration system for use in an endoscopie imaging system. The system provides for the automated cleaning of poorly prepared patients during a colonoscopy procedure as well as automated cleaning of an imaging system of an endoscope. The invention analyzes images obtained from an image sensor to detect the presence of an obstructed field of view, whereupon a wash routine is initiated to remove the obstruction. The wash routine may be adjusted in accordance with environmental conditions within the patient that are sensed by one or more sensors within the endoscope. In another embodiment, insufflation is automatically controlled to inflate a patient's colon as a function of one or more sensor readings obtained from one or more environmental sensor(s) on, the endoscope.
