Abstract
Abstract A unit for correctly placing an intrauterine contraceptive device (IUCD) in the female uterine cavity while preserving the sterility of the IUCD, the unit comprising a plunger attached at its leading end to one end of the IUCD for manipulation of the IUCD into and out of a tubular inserter by manual control exerted upon the trailing end of the plunger which projects beyond the trailing end of the tubular inserter.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
202 words
An intrauterine assembly comprising: an intrauterine device of a flexible material with a retentive memory having a curved portion and a trailing end portion, placement apparatus for placing said device within the uterine cavity, said apparatus comprising: a. a plunger, b. severable means connecting the leading end portion of the plunger to the device, c. a tubular inserter having an internal diameter of a size within which the plunger, said connecting means and said device can be disposed, the combined lengths of the connecting means and the plunger being so related to the length of the inserter that the trailing end portion of the plunger can extend beyond the trailing end of the inserter with a portion of the device extending beyond the leading end of the inserter, whereby the trailing end portion of the plunger can be pulled further out of the inserter to pull the device through force carried by said severable connecting means further into said inserter to assume a more linear configuration for said device curved portion, the device being expelled out of the inserter to assume its normal shape by pushing on the exposed trailing end portion of the plunger to move it back into the inserter.
Claim 2
Dependent Claim
202 words
An intrauterine assembly comprising: an intrauterine device of a flexible material with a retentive memory having a curved portion and a trailing end portion, placement apparatus for placing said device within the uterine cavity, said apparatus comprising: a. a plunger, b. severable means connecting the leading end portion of the plunger to the device, c. a tubular inserter having an internal diameter of a size within which the plunger, said connecting means and said device can be disposed, the combined lengths of the connecting means and the plunger being so related to the length of the inserter that the trailing end portion of the plunger can extend beyond the trailing end of the inserter with a portion of the device extending beyond the leading end of the inserter, whereby the trailing end portion of the plunger can be pulled further out of the inserter to pull the device through force carried by said severable connecting means further into said inserter to assume a more linear configuration for said device curved portion, the device being expelled out of the inserter to assume its normal shape by pushing on the exposed trailing end portion of the plunger to move it back into the inserter.
Claim 3
Dependent Claim
63 words
A placement unit as claimed in claim 1 further comprising a sealed package with the tubular inserter, the plunger and the intrauterine device therein, with the plunger and intrauterine device situated in a beginning position with the trailing end portion of the plunger extending beyond the trailing end of the inserter so that the trailing end portion of the plunger can be grasped.
Claim 4
Dependent Claim
41 words
An intrauterine assembly as in claim 1 wherein the said severable connecting means is located outside of said inserter when the device has been expelled from the inserter into the uterus in a position where said connecting means can be severed.
Claim 5
Dependent Claim
18 words
A combination according to claim 3 further comprising an enlargement comprising a free leading end of the device.
Claim 6
Dependent Claim
25 words
A combination according to claim 4 wherein the enlargement rests upon and projects beyond the leading portion of the inserter when in the loaded position.
Claim 7
Dependent Claim
15 words
A combination according to claim 3 wherein the severable connecting means comprises a tension-transmitting thread.
Claim 8
Dependent Claim
33 words
A combination according to claim 3 wherein the severable connecting means comprises an elongated coupling piece adapted to transfer both tensile and compressing forces betwEen the device and the plunger without appreciable deflection.
Claim 9
Dependent Claim
68 words
A combination according to claim 3 wherein the severable connecting means comprises a relatively thin cord of material which transmits tension to enable the plunger to load the device within the inserter by pulling upon the plunger and buckles under compression so that the force of ejection caused by pushing upon the plunger will first collapse and gather the cord and thereafter cause the device to be displaced.
Claim 10
Dependent Claim
28 words
An intrauterine assembly as in claim 1 wherein said severable connecting means joins the leading end portion of the plunger to a trailing end portion of the device.
