Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
110 words
An inflatable intrauterine device to control uterine bleeding comprising: (1) an insertion means which facilitates insertion of the device into the uterus, (2) an inflatable portion attached to and surrounding said insertion means which, when inflated, substantially conforms to the shape of the uterus, the wall of said inflatable portion being of a thickness sufficient to exert pressure on the uterine wall to control uterine bleeding, and (3) a tubular inflation channel connected to and in communication with the interior of said inflatable portion, said inflation channel containing distally located pores through which said inflatable portion can be inflated and deflated once the device has been inserted into the uterus.
Claim 2
Dependent Claim
110 words
An inflatable intrauterine device to control uterine bleeding comprising: (1) an insertion means which facilitates insertion of the device into the uterus, (2) an inflatable portion attached to and surrounding said insertion means which, when inflated, substantially conforms to the shape of the uterus, the wall of said inflatable portion being of a thickness sufficient to exert pressure on the uterine wall to control uterine bleeding, and (3) a tubular inflation channel connected to and in communication with the interior of said inflatable portion, said inflation channel containing distally located pores through which said inflatable portion can be inflated and deflated once the device has been inserted into the uterus.
Claim 3
Dependent Claim
22 words
An intrauterine device as described in claim 1 in which all or a portion of said inflatable portion has been rendered radioopaque.
Claim 4
Dependent Claim
26 words
An intrauterine device as described in claim 2 in which radioopacity has been provided by means of the inclusion, in said inflatable portion, of radioopaque particles.
Claim 5
Dependent Claim
26 words
An intrauterine device as described in claim 2 in which radioopacity has been provided by means of the inclusion, in said inflatable portion, of radioopaque filaments.
Claim 6
Dependent Claim
35 words
An intrauterine device as described in claim 1 in which said inflatable portion has disposed thereon at its proximal end twin apical projections designed to conform to and block the entrances to the fallopian tubes.
Claim 7
Dependent Claim
53 words
An intrauterine device as described in claim 1 having a second tubular channel, separate from said inflation channel and attached to the outer surface of the wall of said inflatable portion, containing proximally located pores to permit drainage of blood and other uterine debris once the device has been inserted into the uterus.
Claim 8
Dependent Claim
31 words
An intrauterine device as described in claim 6 in which all or a portion of said inflatable portion has been rendered radioopaque by the inclusion therein of radioopaque particles or filaments.
Claim 9
Dependent Claim
35 words
An intrauterine device as described in claim 7 in which said inflatable portion has disposed thereon at its proximal end twin apical projections designed to conform to and block the entrances to the fallopian tubes.
Claim 10
Dependent Claim
55 words
An intrauterine device as described in claim 8 in which said tubular inflation channel is adapted at its distal end by means which permit said tubular inflation channel to be sealed once said inflatable portion has been inflated and unsealed to permit an inflating fluid to be bled from the interior of said inflatable portion.
Claim 11
Dependent Claim
16 words
An intrauterine device as described in claim 9 wherein said means comprise a one way valve.
