US Patent:

43745237, Feb 22, 1983

Filed:

Aug 15, 1975

Appl. No.:

5/605217

Inventors:

In B. Yoon - Timonium MD

International Classification:

A61B 1712
A61B 106

US Classification:

128326

Abstract:

A ring applicator device and method for applying an elastic occluding ring to an anatomical tubular structure which comprises an inner cylinder slidably disposed within an outer cylinder, forceps means slidably disposed within said inner cylinder, and means for moving said forceps means into and out of the inner cylinder and for ejecting an elastic ring from the end of said inner cylinder by displacing said outer and inner cylinders relative to each other. The ring applicator device and method is particularly effective in withdrawing a reproductive tubular member inside of the inner cylinder, thereby forming a loop therein, and displacing the inner cylinder relative to the outer cylinder to eject the elastic ring around said loop, in a one-step operation.

International Classification:

A61B 1712

US Classification:

128326

Abstract:

A method for sterilizing the human female by tubal ligation comprising the use of a ring applicator device having forceps means slidably mounted inside a cylindrical tube for grasping the Fallopian tube and pulling it within the device and means for pushing or otherwise displacing an elastic or stretchable ring over the portion of the tube held within the device, thereby effecting a ligature thereof. The procedure is preferably used in conjunction with a viewing device such as a laparoscope or a culdoscope. The placement of the elastic ring on the tubes eliminates the need for time-consuming procedures which are discomforting to the patient and the use of bulky and expensive equipment. Moreover, depending upon the size and elastic power of the rings, the sterilization can be made permanently or reversibly, as desired. The device and method are also applicable to the sterilization of the human male by the ligature of the vas.

Inventors:

In Bae Yoon - Timonium MD

International Classification:

A61B 1712
A61B 1722

US Classification:

128 6

Abstract:

A multiple ring applicator device and method for applying elastic occluding rings to an anatomical tubular structure which comprises a laparoscope which contains a ring applicator device integral therewith, the ring applicator device and the laparoscope cooperating to effect the application of multiple elastic occluding rings to the tubular structures without the necessity of removing the ring applicator device from the patient's body for reloading purposes.

Filed:

Sep 5, 1979

Appl. No.:

6/072683

Inventors:

In B. Yoon - Timonium MD

International Classification:

A61B 1712

US Classification:

128327

Abstract:

A one-piece, compound elastic member comprising two substantially solid, like bodies, each having a central aperture, the apertures being expandable for receiving a tubular anatomical structure drawn therethrough, each body being composed of elastic, non-tissue reactive material for applying symmetrical radial inward pressure on the tubular structure, when released to the force of the elasticity, the bodies having an operative position and a rest position and an integral, elastic interconnection between the two bodies, the interconnection being under stress in the operative position of the bodies for urging the bodies in the operative position back into the rest position and for thereby applying asymmetrical pressure on the tubular structure, whereby an anatomical tubular structure drawn through the apertures while expanded, and in the operative position, is ligated by the release of the apertures to the elasticity of the bodies and the release of the bodies to the elasticity of the interconnection.

US Classification:

128 6

Abstract:

A multiple occlusion ring applicator device and method for applying elastic occluding rings to an anatomical tubular structure which comprises an inner cylinder, an intermediate cylinder and an outer cylinder, said cylinders being slidably disposed with respect to each other, and forceps means slidably disposed within said inner cylinder, said inner cylinder, said intermediate cylinder, said outer cylinder and said forceps means cooperating to effect the application of multiple elastic occluding rings to the tubular structures without the necessity of removing the instrument from the patient's body for reloading purposes.
