I, MARCUS ALLEN, B.A. Dublin, L.R.C.P. Ed., and L.R.C.S. Ed., of 184
Islington, Liverpool, in the County of Lancaster; Physician and Surgeon; do
hereby declare the nature of this invention to be as follows:-
This invention relates to catheters and bougies so constructed as to be more
economical in cost, economize space in carriage, and be more readily dried after
use and thus less likely to deteriorate, than instruments of this kind as heretofore
made and used.
According to this invention the catheter or the bougie is made reversible, slightly
longer than those in ordinary use, and solid above the "eyes." Each instrument
may comprise two catheters or two bougies of the same form, and if the surgeon
introduces either end alternately the instruments will last much longer than those
of the ordinary non-reversible description. Again, each instrument may be a
combination, one end being a catheter a bole or a bougie a bole, and the other end
being a catheter or a bougie of the ordinary form. Or again, two different sizes
may be combined in one catheter or one bougie.
The instruments are made of rather greater length than those in ordinary use
so as to prevent undue pressure when a bole end, or tapering end, is external to
the glans penis, and also to meet the contingency of either "eye" of the catheter
becoming roughened from use and that portion of the instrument being, therefore,
unfit to be introduced into the urethral canal. The catheters being solid above
the "eyes" facilitates the escape of urine and also renders the instruments more
easy to dry after use.

Improvements in Catheters and Bougies.
I, MARCUS ALLEN, B.A. Dublin, L.K.C.P. Ed., L.R.C.S. Ed., formerly of 134
now of 136 Islington, Liverpool, in the County of Lancaster; Surgeon (Retired);
do hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following

page_text: This invention relates to catheters and bougies so constructed as to be more
economical in cost, economise space in carriage, occupy less time in oiling for use,
and be more readily dried after use and thus less likely to deteriorate, than
instruments of this kind as heretofore made and used.
According to this invention the instruments comprise, practically, two catheters
or two bougies in one. The instruments are made slightly longer than those in
ordinary use, and the catheters are made solid above the eyes. Each instrument
is "reversible" and may comprise two catheters or two bougies of the same form
and size, and if the surgeon introduces either end alternately the instrument will
last much longer than one of the ordinary non-" reversible" description. Again,
each instrument may be a combination, one end being a catheter a boule or a
bougie a boule, and the other end being a catheter or a bougie of the ordinary
form, each end being of the same size. Or again, two different sizes as well as
forms, may be combined in one catheter and one bougie.
In the accompanying drawings Fig. 1 is an elevation of a reversible" bougie
made according to my invention, one end A being a bougie a boule, and the other
end B being a bougie of the ordinary form. Fig. 2 is an elevation and Fig. 3 is
a longitudinal section of a reversible" catheter made according to my invention
cne end C being a catheter a boule, and the other end 1 being a catheter a size
smaller of the ordinary form.

In Figs. 2 and 3, the "eyes" E of the catheter are shown in line, but I may
alter this arrangement if I should find it desirable to do so.
The "reversible" instruments are made of rather greater length than those in
ordinary use so as to prevent undue pressure when a boule end, or tapering end,
is external to the glans penis, and also to meet the contingency of either "eye" E
of the catheter becoming roughened from use and that portion of the instrument
being, therefore. unfit to be introduced into the utethral canal. The catheters
being solid above the eyes, and curved into the back of the instrument as shown in
Fig. 3, facilitates the escape of urine and also renders the catheter more easy to dry
after use.

:
In case the surgeon should require to use the "reversible cathet for the
purpose of washing out the bladder, it is to be noted that the instrun ent is of
greater length than that in general use, and he has merely to remove ether end
with a knife when he has an ordinary catheter of the usual length to which to
attach tubing etc.
my said
Having now particularly described and ascertained the nature of
invention, and in what manner the same is to be performed, I declare that what
I claim is:
1. A bougie made double ended or reversible so that either end may be used, and
which may combine two different sizes as well as forms, substantially as described
and shown in Fig. 1 of the accompanying drawings.
2. A catheter made double ended or reversible so that either end may be used,
and having solid ends above the eyes curved into the back of the instrument, and
which may combine two different sizes as well as forms, substantially as and for
the purpose hereinbefore described and illustrated in Figs. 2 and 3 of the
accompanying drawings.
