Aug. 25, 1953 SALM INSTRUMENT FOR CLOSING THE UR'ETHRA Filed Aug. 31, 1950 INVENTOR HANS SA-LM a5 6. 91M

AGENT Patented Aug. 25, 1953 Hans Salm, Munich, Germany Application August 31, 1950, Serial No. 182,520 In Germany April 27, 1949 9 Claims.

The object this invention aims at is to provide an instrument which enables to seal the urethra hermetically in a dependable manner. Such an instrument is requested for inst., if the sphincter fails to function, with chronic nocturnal enuresis etc. The contrivance according to this invention may be used also as a condome.

' The instrument according to this invention is an outer flange and. an inner enlargement, so that'due to the elasticity which prevails between the flange and the enlargement a biasing pressure is exercized on the parts of the urethra which are located near the contraction of the hollow body, whereby the complete seal of the urethra is assured.

A special implement is used for inserting the said device'into the urethra. This former consists of a mandrel with a head thereon, which,

when an axial thrust is applied to the mandrel,

will have a'biasing effect on the cap of the enlargement; the said implement has, moreover, a

tapered part for mutual engagement with expanding members of a retaining and guiding sleeve for the mandrel, which members have been shaped as jaws to grip a stiifening of the flange.

The figures in the attached drawing are showing diagramatically an embodiment of'this invention, of which Fig. 1 is a vertical section through the instrument as per this invention together with the implement for inserting'the contrivance into the urethra,

; instrument.

The device consists of a hollow body of elastic material, such as rubber, to be inserted into the mouth of the urethra. .This hollow body is provided with a contraction 3 between an outer 'flange I and an inner enlargement 2.

The enlargement 2 is closed at its face by a cap 4, which has been drawn inwards to assume the shape of a' dish, what is very important with regard to the stability of the shape and the'dependability of' the'seal. The body (I, 2, 3, 4) is provided with an insertion 5 in the shape of a network of mutually crossing filaments. Y of this networkof crossing filaments is to pro- -'-vide that, if the enlargement 2 is stretched m The special purpose 2 the direction of the arrow 6, this enlargement assumes an exactly cylindrical shape, which corresponds in diameter to that of the contraction 3. The network of filaments is intended, moreover, to balance all stresses which might arise in the rubber body and thus to make for the necessary tearing strength. The cap 4 is provided with an additional insertion I, e. g. in the shape of a disk of corduroy, whose diameter must be smaller than the inner diameter of the contraction 3. This insertion serves as an abutment for the inserting implement-to be described belowif the body (I, 2, 3, 4) is stretched in the direction of the arrow 6. This insertion protects, moreover, within the sphere of the cap 4 the network 5 against mechanical destructions caused by introducing the mandrel.

Within the flange I is located a stiffening 8, preferably in the shape of a metal disk, which is indented at its periphery. The network of filaments is anchored to this stilfening 8 (i. e. at the teeth of the metal disk). Besides this the flange I'is reinforced by filament insertions 9 arranged in zig-zag, which surround the stiffening 8.

The introduction of the rubber body into the .urethra. is performed by means of a mandrel III, which at onev of its extremities isprovided with a ball-shaped head I I. The concavity of the cap -4 is curved along the convexity of the balla gliding movement in a, e. g. metallic sleeve I2, which latter acts as a guide.

the sleeve is provided with peripheral slots I3, which form expanding members I4, which in their turn form both jaws I5 and abutment faces IS. The intermediate space I! between the jaws I5 and the abutments I6 is contracted and serves for co-operation with a tapered part I8 of the mandrel I0, so that when the mandrel I0 is shifted in its sleeve I2 in the direction of the arrow IS the members I4 become expanded. At

shaped head to avoid lateral slipping of the head off the cap. The mandrel I0 is able to perform In its fore part the free extremity of the mandrel is a pressure disk 20 for the action of the thumb of the hand which is handling the device- The free extremity of the sleeve I2 is correspondingly shaped as an abutment for the index and middle finger of the .same hand.

J E The manipulation of this device is as follows:

the parts of the latter is at first applied to the body (I, 2, 3, 4) in the position which may be seen in Fig. 1.

21 are brought in operating position between the 'thumb of the hand in action and the index and The mandrel I I) together with its sleeve I4 and The pressure disk 20 and the abutment middle finger of the same hand, and then a pressure is exerted by the thumb on the disk 20 in the direction of the arrow l9. By moving the mandrel l within the sleeve l2 the tapered part i8 is brought to mutual engagement with the contractions ll of the expanding members l4, so that the latter are expanded to the effect that the stiffening 8 of the flange I is clamped between the jaws I and the abutments '16 of the expanding members and thus the rubber body becomes retained during the continued advance of the mandrel l9. lhe head ll of the mandrel l0 strikes during the continued axial displacement of the latter the inner wall of the cap 4. The enlargement 2 is stretched and shrunk against the effect of its elasticity to assume the cylindrical shape with the diameter of the contraction 3, the filament network 5 assuring the stability of the shape or" this cylinder. Now the rubber body has been shaped to the diameter which allows its introduction into the urethra. If this has been accomplished the mandrel l0 becomes released of the pressure of the thumb and is returned subsequently, owing to the elasticity of the rubber body. The rubber body assumes once more the shape shown in Fig. 1, wherein the parts of the urethra which are near the contraction 3 are engaged by the l, 2 and 3 to form a seal by clamping them together. Now the mandrel is removed together with its sleeve.

According to this embodiment of this invention the pressure disk 26 has been shaped at the same time as a cover for a case 22, in which the entire instrument, 1. e. the rubber body as well as the stretching implement are kept, if they are out of use. In this example the cover 20 has been provided with a threaded part for having it screwed on to the case.
