摘要： A method of delivering a substance to a fallopian tube of a patient which includes obtaining transcervical access to a fallopian tube with an everting catheter. Access to the fallopian tube is obtained by everting an everting element of the everting catheter in the fallopian tube. A substance selected from the group consisting of biological material and cytotoxic agents is then delivered through the everting catheter to the fallopian tube to deposit the substance in the fallopian tube.

摘要： A method of tubal recanalization comprising advancing an everting catheter adapted for dilatation and an endoscope to a position adjacent the site of a stenosis in an internal tubal passage of a patient. The everting catheter includes an endoscope lumen and the endoscope is within the endoscope lumen. The everting element is everted to a location within the stenosis and is then expanded to reduce the stenosis. When the tubal passage has been opened sufficiently, the everting element is retracted. The site of the stenosis is viewed using the endoscope and such viewing may be carried out prior to expansion of the everting element to locate the site as well as after the everting element has been retracted.

摘要： A method of positioning an elongated instrument in an everting catheter is disclosed. The everting catheter includes an inflatable everting element which circumscribes a region of the instrument and which is inflated to grip the instrument. The everting catheter and instrument extend into a patient to a desired region within the body. Flush solution is introduced between the everting element and the instrument, and the instrument is moved relative to the everting element while the flush solution is between the everting element and the instrument.

摘要： A catheter comprising an elongated, flexible catheter body having a distal end portion which is curved in an unstressed condition. The catheter body has a through lumen and a mandrel lumen. A mandrel is provided in the mandrel lumen, and the mandrel has a distal end portion configured to at least partially straighten the curve of the distal end portion of the catheter body. The mandrel is movable between an extended position in which the mandrel at least partially straightens the curve of the distal end portion of the catheter body and a retracted position in which the catheter body is more curved than in the extended position of the mandrel.

摘要： An everting catheter system comprising an elongated outer tubular body having an outer body lumen and an opening leading from the outer body lumen, an elongated inner tubular body movable longitudinally in the outer body lumen and having an inner body lumen and an everting element coupled to the outer body and the inner body so that with movement of the inner body longitudinally in the outer body lumen the everting element can be everted and inverted. The system also includes an elongated instrument, such as a transfer catheter, movable longitudinally in the inner body lumen relative to the inner body. A coupling releasably couples the instrument to the outer body in a substantially fixed longitudinal position with respect to the outer body.

摘要： A catheter comprising an elongated catheter body having a lumen with a distal opening, an elongated inner tube having a flexible distal end portion and a flexible everting element coupled to the catheter body and the inner tube so that the everting element can be inverted and everted to the distal opening. The inner tube has an inner tube lumen which extends through the distal end portion of the inner tube. The distal end portion of the inner tube includes a flexible tubular layer and a flexible reinforcing layer which reinforces the tubular layer and inhibits radial collapse of the inner tube lumen in the distal end portion of the inner tube.

摘要： An intubation device comprises an imaging conduit including an illumination conduit for delivering illumination to a distal end of the device and an image-receiving conduit for communicating images from the distal end of the device to the proximal end of the device. The device also comprises a flushing conduit for delivery of fluids and/or gases to the distal end of the device. The image conduit and the flushing conduit are attached at the distal end of the device. The distal end of the device can be manipulated by advancing the imaging conduit in an axial direction while maintaining the flushing conduit fixed in place. Furthermore, a length adjustment member is provided for adjusting the extent to which the distal end of the device extends beyond a distal end of an endotracheal tube which is inserted over the imaging and flushing conduits. The illuminating conduit and the image-receiving conduit terminate in separate ports at the distal end of the device. Furthermore, a substantial portion of the device is disposable, so that time consuming sterilization is not necessary.

摘要： A valvuloplasty catheter comprising a catheter body having a through lumen, a tube extending through the lumen and having a distal end portion extending distally beyond the distal end of the catheter body and movable axially in the lumen relative to the catheter body. A radially expandable and axially contractable balloon is coupled, respectively, to the catheter body at the distal end portion of the tube. The balloon has a central region between the opposite end portions of the balloon which is of greater radial dimension in the relaxed condition than the opposite end portions and transition regions between the central region and the opposite end portions. The catheter body has a distal end portion which is less stiff than the region of the catheter body immediately proximal of the distal end portion of the catheter body.

摘要： An endoscope comprising a reusable eyepiece and a disposable distal section mounted on the eyepiece in a predetermined angular orientation so that light can be conducted from the eyepiece through the distal section and an image can be conducted from the distal section to the eyepiece. Image conduction is accomplished, in part, by a somewhat resilient, nontubular image-conducting rod. Focusing is accomplished by a focusing ring which rotates, but does not translate, on the housing. The distal section is adapted to be at least partially received within a patient and can be introduced by an introducer attached to the distal section.
