PROVISIONAL SPECIFICATION.
An Improved Manufacture of Sounds or Probes, Bougies, Catheters,
Canulas, and other similar Instruments.
We, GEORGES EUGÈNE GAIFFE fils, of 40, Rue Saint André des Arts, Paris,
France, Instrument Maker, and FRÉDÉRIC CASASSA, of 10, Rue Jacquart Pantin
(Seine) France, Manufacturer of India-rubber Goods, do hereby declare the nature
of this invention to be as follows:
This invention relates to an improved manufacture of sounds or probes, bougies,
catheters, canulas, and other similar instruments.
These instruments have hitherto been made either of soft india-rubber or of
fabric coated with resinified oils such as those known as elastic gum bougies or
catheters. Those of the first mentioned kind are difficult of insertion but withstand
boiling water and acid solutions used for cleaning them and destroying disease
germs so that they may be repeatedly used, although frequent heating ultimately
destroys them. Those made of elastic gum possess greater rigidity, are easier of
insertion, and susceptible of more general application but can only be used once as
they cannot resist acids or the temperature necessary for cleansing and rendering
them aseptic. Hard india-rubber has also been used, but instruments made of this
material are too hard and brittle.
The improved instruments of our invention combine the good qualities of the
three materials before mentioned without possessing their disadvantages.
According to our invention, we make the instrument of semi-soft or flexible
hard rubber which, while possessing a rigidity equal to those made of elastic gum,
is exceedingly supple and is capable of bending to curves of very small radius.
Instruments made of this material require no core of fabric as it is absolutely
homogeneous throughout. This material can be placed in boiling water or in a
stove or washed in acidulated or other solutions, and may be colored as desired.

The improved instruments of our invention combine the good qualities of the
three materials before mentioned without possessing any of their disadvantages.
According to our invention, we make the instrument of what is known in France
as "mi-souple or flexible hard rubber which while possessing a rigidity equal to
those made of elastic gum, is exceedingly supple and is capable of bending to
curves of very small radius. Instruments made of this material require no core of
fabric as it is absolutely homogeneous throughout, and may be placed in boiling
water or in a stove or washed in acidulated or other solutions and may be colored
as desired.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is
The manufacture of sounds or probes, bougies, catheters, canulas, and other
similar instruments of flexible hard rubber of the kind herein specified.
