Abstract
Abstract An apparatus for causing a semi-permanent constriction of an intracorporeal duct comprises a synchronous magnetic coupling having driving and driven rotors and in accordance with the invention, a flexible transmission connecting the output shaft of the driven rotor to an intracorporeal valve provided with flaps which control the cross-section of the duct. A feature of the invention is that the extracorporeal housing of the driving rotor and the intracorporeal housing of the driven rotor are adapted for interlocking while leaving a clearance therebetween for insertion of a skin projection.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
103 words
An apparatus for controlling an intracorporeal organ, from the outside of the body of a human or animal, said apparatus comprising: a rotating magnetic field transmission system including driving and driven members, said driven member having an output shaft; an extracorporeal casing containing said driving member; an intracorporeal casing containing said driven member; intracorporeal control means for controlling the intracorporeal organ; and flexible transmission means connecting the output shaft of the driven member to the control means, the said casings having opposite surface portions which are adapted for interlocking while leaving a clearance therebetween adapted to receive a subStantially cylindrical skin projection therein.
Claim 2
Independent Claim
103 words
An apparatus for controlling an intracorporeal organ, from the outside of the body of a human or animal, said apparatus comprising: a rotating magnetic field transmission system including driving and driven members, said driven member having an output shaft; an extracorporeal casing containing said driving member; an intracorporeal casing containing said driven member; intracorporeal control means for controlling the intracorporeal organ; and flexible transmission means connecting the output shaft of the driven member to the control means, the said casings having opposite surface portions which are adapted for interlocking while leaving a clearance therebetween adapted to receive a subStantially cylindrical skin projection therein.
Claim 3
Independent Claim
201 words
An apparatus for controlling, from the outside of the body of a human or animal, the cross-section of a natural or artificial duct within the body, said apparatus comprising: a synchronous magnetic coupling having driving and driven rotors, the driven rotor having an output shaft; an extracorporeal casing for the driving rotor and an intracorporeal casing for the driven rotor; motor means, operatively connected to the driving rotor, for causing an adjustable rotation thereof; intracorporeal valve means adapted to bring about the constriction of the duct; and flexible transmission means connecting the output shaft to the valve means, the two rotors having concentric cylindrical facing surface portions, the intracorporeal casing having a substantially cylindrical concentric surface portion in which the driven rotor is lodged, the extracorporeal casing having a further substantially cylindrical concentric surface portion in which the driving rotor is lodged, the said further surface portion having a substantially annular projection which is adapted for being concentrically arranged about the said substantially cylindrical portion and radially spaced therefrom, whereby a clearance is provided for lodging a substantially cylindrical skin projection located between the said concentric cylindrical surface portions of the two rotors when placed in operative relation with the body.
Claim 4
Independent Claim
201 words
An apparatus for controlling, from the outside of the body of a human or animal, the cross-section of a natural or artificial duct within the body, said apparatus comprising: a synchronous magnetic coupling having driving and driven rotors, the driven rotor having an output shaft; an extracorporeal casing for the driving rotor and an intracorporeal casing for the driven rotor; motor means, operatively connected to the driving rotor, for causing an adjustable rotation thereof; intracorporeal valve means adapted to bring about the constriction of the duct; and flexible transmission means connecting the output shaft to the valve means, the two rotors having concentric cylindrical facing surface portions, the intracorporeal casing having a substantially cylindrical concentric surface portion in which the driven rotor is lodged, the extracorporeal casing having a further substantially cylindrical concentric surface portion in which the driving rotor is lodged, the said further surface portion having a substantially annular projection which is adapted for being concentrically arranged about the said substantially cylindrical portion and radially spaced therefrom, whereby a clearance is provided for lodging a substantially cylindrical skin projection located between the said concentric cylindrical surface portions of the two rotors when placed in operative relation with the body.
Claim 5
Dependent Claim
33 words
An apparatus as claimed in claim 2, wherein the said motor means have a rotatable shaft, a wheel, operatively connected to said shaft so as to be rotated thereby, bearing a graduated scale.
Claim 6
Dependent Claim
46 words
An apparatus as claimed in claim 2, wherein the said valve has two flaps mounted for parallel mutual displacements and forming a clamping means for the duct, a screw, provided with left-handed and right-handed threads, being rotatably mounted and operatively connected to the flexible transmission means.
Claim 7
Dependent Claim
32 words
An apparatus as claimed in claim 2, further comprising speed multiplier means connecting the motor means to the driving rotor and speed reducer means connecting the driven rotor to the output shaft.
