Improvement to an adornable binocular device having a telescope pair including a pivoting coupling between each telescope and arm and a second releasably slidable coupling between each telescope and arm.

Convergence adjustment mechanism

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.

Method of delivering a substance to a fallopian tube

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be carried out prior to expansion of the everting element to locate the site as well as after the everting element has been retracted.

Method of tubal recanalization and catheter system therefor

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.

Apparatus and method for independent movement of an instrument within a

An everting catheter system comprising an outer tube having an outer catheter lumen and an opening leading from the outer catheter lumen, an inner catheter movable longitudinally in the outer catheter lumen and having an inner catheter lumen and an everting element coupled to the outer catheter and the inner catheter so that with movement of the inner catheter distally in the outer catheter lumen, the everting element can be everted through the opening. An elongated instrument is movable longitudinally in the inner catheter lumen relative to the inner catheter. Indicia are provided on the inner catheter and the instrument for indicating at least one longitudinal position of the instrument relative to the distal end of the everting element.
