Abstract: Improvement to an adornable binocular device having a telescope pair and an adjustable inter-pupillary distance (IPD) where both telescopes move simultaneously and substantially the same distance when the IPD is adjusted, the improvement including a mechanism for releasably preventing unintentional adjustment the IPD and including a first releasably pivoting coupling between each telescope and arm and a second releasably slidable coupling between each telescope and arm.

Abstract: An everting catheter system which includes an elongated outer catheter having an outer catheter lumen and an opening, an elongated inner catheter movable in the outer catheter lumen and having the inner catheter lumen adapted to receive an elongated instrument and an everting element coupled to the outer catheter and the inner catheter. With movement of the inner catheter in the outer catheter lumen, the everting element can be everted through the opening of the outer catheter. A controller is coupled to the inner catheter for moving the inner catheter in the outer catheter lumen and for moving the instrument in the inner catheter lumen.

Abstract: 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.

Abstract: 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.
