Abstract
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.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
138 words
A ring applicator device used for applying an elastic occluding ring to an anatomical tubular structure which comprises an inner cylinder and an outer cylinder, said inner cylinder being slidably disposed within said outer cylinder, and forceps means slidably disposed within said inner cylinder, said forceps means including means for grasping and releasing said anatomical tubular structure, the proximal end portion of said inner cylinder having means thereon tO selectively retain on its outer end surface at least two elastic occluding rings and said outer cyinder having an expandable end portion which cooperates with the proximal end portion of the inner cylinder to define a means for sequentially ejecting the elastic occluding rings from the inner cylinder after axially displacing the outer and inner cylinders relative to each other to position said expandable end portion behind a ring.
Claim 2
Dependent Claim
138 words
A ring applicator device used for applying an elastic occluding ring to an anatomical tubular structure which comprises an inner cylinder and an outer cylinder, said inner cylinder being slidably disposed within said outer cylinder, and forceps means slidably disposed within said inner cylinder, said forceps means including means for grasping and releasing said anatomical tubular structure, the proximal end portion of said inner cylinder having means thereon tO selectively retain on its outer end surface at least two elastic occluding rings and said outer cyinder having an expandable end portion which cooperates with the proximal end portion of the inner cylinder to define a means for sequentially ejecting the elastic occluding rings from the inner cylinder after axially displacing the outer and inner cylinders relative to each other to position said expandable end portion behind a ring.
Claim 3
Dependent Claim
138 words
A ring applicator device used for applying an elastic occluding ring to an anatomical tubular structure which comprises an inner cylinder and an outer cylinder, said inner cylinder being slidably disposed within said outer cylinder, and forceps means slidably disposed within said inner cylinder, said forceps means including means for grasping and releasing said anatomical tubular structure, the proximal end portion of said inner cylinder having means thereon tO selectively retain on its outer end surface at least two elastic occluding rings and said outer cyinder having an expandable end portion which cooperates with the proximal end portion of the inner cylinder to define a means for sequentially ejecting the elastic occluding rings from the inner cylinder after axially displacing the outer and inner cylinders relative to each other to position said expandable end portion behind a ring.
Claim 4
Dependent Claim
138 words
A ring applicator device used for applying an elastic occluding ring to an anatomical tubular structure which comprises an inner cylinder and an outer cylinder, said inner cylinder being slidably disposed within said outer cylinder, and forceps means slidably disposed within said inner cylinder, said forceps means including means for grasping and releasing said anatomical tubular structure, the proximal end portion of said inner cylinder having means thereon tO selectively retain on its outer end surface at least two elastic occluding rings and said outer cyinder having an expandable end portion which cooperates with the proximal end portion of the inner cylinder to define a means for sequentially ejecting the elastic occluding rings from the inner cylinder after axially displacing the outer and inner cylinders relative to each other to position said expandable end portion behind a ring.
Claim 5
Dependent Claim
17 words
The device of claim 1, wherein the inner cylinder is provided with a puncturing proximal edge portion.
Claim 6
Dependent Claim
42 words
The device of claim 1, wherein the inner cylinder is in screw engagement with the outer cylinder and means are provided for rotating the outer tube about the inner tube, thereby axially displacing the outer tube with respect to the inner tube.
Claim 7
Dependent Claim
31 words
The device of claim 1, wherein a plurality of grooves are provided on the end portion of the inner cylinder, each of said grooves being adapted to receive an elastic ring.
Claim 8
Dependent Claim
45 words
The device of claim 1, wherein when the inner cylinder is loaded with a plurality of elastic occluding rings, the expandable portion of the outer cylinder extends over all of said rings except the ring located most proximal to the end of the inner cylinder.
Claim 9
Dependent Claim
28 words
The device of claim 1, wherein the forceps means are spring loaded so that they spring open when they are displaced from the end of the inner cylinder.
Claim 10
Dependent Claim
15 words
The device of claim 2, wherein the puncturing edge portion has a syringe needle-like shape.
Claim 11
Dependent Claim
27 words
The device of claim 1, wherein a laparoscope is combined with the ring applicator, said laparoscope and ring applicator being in juxtaposition with respect to each other.
Claim 12
Dependent Claim
29 words
The device of claim 1, wherein a locking device is associated with the outer and inner cylinders to prevent relative movement of said cylinders with respect to each other.
Claim 13
Dependent Claim
38 words
The device of claim 1, wherein handle means is attached to the inner and outer cyclinders and a ratchet means is associated with said handle means to prevent relative movement of said cylinders with respect to each other.
