摘要： A drug-infusing device is implanted into a body cavity such as a bladder. The device is implanted in an uninflated, low profile state. After insertion into the body cavity, the device is filled with a substance, such as a drug, and assumes an increased profile. After the device is filled, it is allowed to float freely within the body cavity. Alternatively, the device can be tethered to a wall of the body cavity. The device delivers the drug at a controlled rate over an extended period of time. In order to deliver the drug at a controlled rate, the device preferably has a pressure-responsive valving member. The flow resistance of the valving member is responsive to the pressure at which the drug is stored within the infusing device. The resistance of the valving member decreases as the pressure within the infusing device decreases, thereby providing a resultant controlled flow rate.

摘要： A delivery device and method for delivering a medical device, such as an infuser, into a body cavity are disclosed. The delivery device includes an ejector tube which slidably extends through a handle. The ejector tube is configured for easy insertion through the urethra into the bladder. A hollow inner tube is located within the ejector tube and includes luer fittings at its distal and proximal ends. The luer fitting at the proximal end of the inner tube is coupled to the handle. Movement of the ejector tube relative to the inner tube causes the distal luer fitting to be withdrawn within the ejector tube and can be used to force an infuser attached to the distal luer fitting from the distal luer fitting. Materials can be transported to the infuser from the proximal luer fitting through the inner tube and out through the distal luer connector.

摘要： A method of viewing an interior passage of a patient using an endoscope and a catheter which includes a catheter body having a distal end and a lumen opening at the distal end and a displacing member. The method comprises advancing the catheter into the passage in the patient with the displacing member extending beyond the distal end of the catheter body when the catheter body is at a region of the passage. The endoscope is provided in the lumen of the catheter with the endoscope being movable longitudinally relative to the catheter and being at a location for viewing the interior passage. The method includes relatively displacing the distal end of the catheter body and material within or forming the passage within a zone of the interior passage utilizing the displacing member and viewing at least a portion of such zone of the interior passage utilizing the endoscope.

摘要： An endoscope including an elongated endoscope body sized and adapted for insertion into a passage, such as a passage of the body of a patient. Optical components are carried by the endoscope body to enable viewing of the passage distally of the distal end of the endoscope body within a field of view of the endoscope. An elongated, resilient member is mounted on and carried by the endoscope body such that the endoscope body and the resilient member are a unitary assembly which can be inserted as a unit into the passage. The resilient member extends beyond the distal end of the endoscope body and is capable of contacting material within or forming the passage and relatively displacing the distal end of the endoscope body and such material within the field of view of the endoscope to enhance viewing of the passage with the endoscope.
