Abstract
Abstract A method of female sterilization comprising the steps of providing a toxic fluid capable of damaging the fallopian tubes which leads to their ultimate occlusion, injecting the fluid into the uterine cavity of the female, and vibrating the fluid within the uterine cavity. Preferably, the fluid is vibrated at ultrasonic frequencies for a time period in the time range of between five seconds and ten minutes. The device used to inject the fluid into the uterine cavity may be used to produce the vibration, and the vibration may be directed at the uterus, which in turn indirectly causes the fluid in the cavity to vibrate. An instrument for performing the method is also disclosed.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
82 words
An instrument for injecting a fluid into a uterine cavity and for dispersing the fluid into the fallopian tubes comprising: a tube having an open end adapted for insertion into the uterine cavity, the interior of said tube adapted for communication with a source of fluid whereby fluid from the source of fluid may flow through said tube and into the uterine cavity; and means for vibrating the fluid within the uterine cavity whereby the fluid is dispersed into the fallopian tubes.
Claim 2
Dependent Claim
82 words
An instrument for injecting a fluid into a uterine cavity and for dispersing the fluid into the fallopian tubes comprising: a tube having an open end adapted for insertion into the uterine cavity, the interior of said tube adapted for communication with a source of fluid whereby fluid from the source of fluid may flow through said tube and into the uterine cavity; and means for vibrating the fluid within the uterine cavity whereby the fluid is dispersed into the fallopian tubes.
Claim 3
Dependent Claim
15 words
An instrument according to claim 1 wherein said vibrating means is mounted on said tube.
Claim 4
Dependent Claim
18 words
An instrument according to claim 1 wherein said vibrating means is capable of vibrating at ultra sonic frequencies.
Claim 5
Dependent Claim
36 words
An instrument according to claim 1 further comprising a rod extending through the interior of said tube and adapted to extend beyond the open end of said tube and wherein said vibrating means vibrates said rod.
Claim 6
Dependent Claim
38 words
An instrument according to claim 4 wherein said rod comprises a uterine sound having a plurality of branch sounds in the region of said uterine sound that is adapted to extend beyond the open end of said tube.
Claim 7
Independent Claim
28 words
A method of dispersing a fluid into fallopian tubes comprising the steps of: injecting the fluid into the uterine cavity; and vibrating the fluid within the uterine cavity.
Claim 8
Independent Claim
28 words
A method of dispersing a fluid into fallopian tubes comprising the steps of: injecting the fluid into the uterine cavity; and vibrating the fluid within the uterine cavity.
Claim 9
Dependent Claim
22 words
A method of dispersing a fluid into the fallopian tubes according to claim 6 wherein said vibrating is at ultra sound frequencies.
Claim 10
Dependent Claim
30 words
A method of dispersing a fluid into fallopian tubes according to claim 6 wherein said vibrating occurs for a duration in the range of between five seconds and ten minutes.
Claim 11
Dependent Claim
32 words
A method of dispersing a fluid into fallopian tubes according to claim 6 comprising the step of vibrating the uterus, which in turn causes the fluid within the uterine cavity to vibrate.
Claim 12
Dependent Claim
25 words
A method of dispersing a fluid into fallopian tubes according to claim 6 wherein said fluid includes a chemical capable of occluding the fallopian tubes.
Claim 13
Independent Claim
48 words
A method of female sterilization comprising the steps of: providing a fluid capable of damaging the fallopian tubes of a female upon contact between the fluid and the fallopian tubes; injecting the fluid into the uterine cavity of the female; and vibrating the fluid within the uterine cavity.
Claim 14
Independent Claim
48 words
A method of female sterilization comprising the steps of: providing a fluid capable of damaging the fallopian tubes of a female upon contact between the fluid and the fallopian tubes; injecting the fluid into the uterine cavity of the female; and vibrating the fluid within the uterine cavity.
Claim 15
Independent Claim
57 words
A method of dispersing a fluid into a tubular structure in the tissue of a living animal, the interior of which tubular structure is in communication with a cavity also formed and defined by the tissue of said living animal, comprising the steps of: injecting the fluid into said cavity; and vibrating the fluid within said cavity.
Claim 16
Independent Claim
57 words
A method of dispersing a fluid into a tubular structure in the tissue of a living animal, the interior of which tubular structure is in communication with a cavity also formed and defined by the tissue of said living animal, comprising the steps of: injecting the fluid into said cavity; and vibrating the fluid within said cavity.
Claim 17
Dependent Claim
22 words
A method of dispersing a fluid into a tubular structure according to claim 12 wherein said vibrating is at ultra sound frequencies.
Claim 18
Dependent Claim
32 words
A method of dispersing a fluid into a tubular structure according to claim 12 wherein said vibrating means occurs for a duration in the range of between five minutes and ten minutes.
Claim 19
Dependent Claim
36 words
A method of dispersing a fluid into a tubular structure according to claim 12 comprising the step of vibrating the tissues surrounding said tubular structure, which in turn causes the fluid within said structure to vibrate.
Claim 20
Dependent Claim
26 words
A method of dispersing a fluid into a tubular structure according to claim 12 wherein said fluid includes a chemical capable of occluding the tubular structure.
