Abstract
Abstract A method of treating hemorrhoids which comprises inserting into the rectum of a subject afflicted therewith a substantially cylindrical shaped insert, comprising a water swellable polymer having a water content of at least 35% by weight, said insert having previously been frozen by being subjected to a temperature below 0° C. for a sufficient amount of time to freeze the free water therein and maintaining said insert with at least a portion thereof outside the sphincter muscle, and apparatus therefore.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
111 words
A package means for treatment of rectal disorder comprising a disposable substantially form retaining package of predetermined shape enveloping a water swellable polymer in gel form comprising at least 35% by weight of water, said gel being selected to provide an insert of sufficient rigidity to be inserted into the rectum after said insert has been cooled to below 0° C. said insert, when frozen, comprising a substantially cylindrical body provided with a substantially conical nose at one end thereof and a rearward collar proximate to the other end thereof, said nose facilitating insertion and said collar preventing initial total passage of the insert beyond the sphincter muscle of the rectum.
Claim 2
Dependent Claim
111 words
A package means for treatment of rectal disorder comprising a disposable substantially form retaining package of predetermined shape enveloping a water swellable polymer in gel form comprising at least 35% by weight of water, said gel being selected to provide an insert of sufficient rigidity to be inserted into the rectum after said insert has been cooled to below 0° C. said insert, when frozen, comprising a substantially cylindrical body provided with a substantially conical nose at one end thereof and a rearward collar proximate to the other end thereof, said nose facilitating insertion and said collar preventing initial total passage of the insert beyond the sphincter muscle of the rectum.
Claim 3
Dependent Claim
89 words
A package means in accordance with claim 1 additionally comprising a forward collar section located upon the cyclindrical body rearwardly of the nose section and forwardly of the real collar, the forward face of said forward collar section having a substantially frustro-conical cross-section and the rearward face of said forward collar section lying in a plane substantially perpendicular to the longitudinal axis of the insert, whereby there is provided a substantially cylindrical midsection between the rearward face of the forward collar and the forward face of said rear collar.
Claim 4
Dependent Claim
35 words
A package means in accordance with claim 1 wherein the rearward collar is displaced a sufficient distance forward of the rear end of the insert to enable the remaining rear portion to be finger held.
Claim 5
Dependent Claim
39 words
A package means in accordance with claim 3 wherein at least one portion of the curved surface of said rear most section is flattened to lie substantially in a plane substantially parallel to the longitudinal axis of the insert.
Claim 6
Dependent Claim
31 words
A package means in accordance with claim 2 wherein at least a portion of said mid-section has a diameter less than the maximum diameter of the nose section of the insert.
Claim 7
Dependent Claim
26 words
A device in accordance with claim 5 wherein said mid-section has a diameter of between 50 and 25% of the maximum diameter of the nose section.
Claim 8
Dependent Claim
28 words
A package means in accordance with claim 2 wherein the diameter of the forward collar is between 150% and 250% of the maximum diameter of the nose section.
Claim 9
Dependent Claim
16 words
A package means in accordance with claim 1 wherein the gel comprises at least 90% water.
Claim 10
Dependent Claim
19 words
A package means in accordance with claim 7 wherein the gel comprises at least 98% by weight of water.
Claim 11
Dependent Claim
30 words
A package means in accordance with claim 8 wherein the device comprises a multi block copolymer of acrylonitrile acrylamide having a water content of between 95 and 99.7% by weight.
Claim 12
Dependent Claim
21 words
A package means in accordance with claim 1 additionally comprising a pharmaceutically acceptable amount of a rectally administrable pharmaceutically active compound.
Claim 13
Independent Claim
94 words
A method of treating hemorrhoids which comprises inserting into the rectum of a subject afflicted therewith a substantially cylindrical insert shaped and dimensioned to enter readily thru the rectal sphincter muscle, said insert comprising a water swellable polymer having a water content of at least 35% by weight, said insert having previously been frozen by being subjected to a temperature below 0° C. for a sufficient amount of time to freeze the free water therein and maintaining said insert with at least a portion thereof outside the sphincter muscle for at least one minute.
Claim 14
Independent Claim
94 words
A method of treating hemorrhoids which comprises inserting into the rectum of a subject afflicted therewith a substantially cylindrical insert shaped and dimensioned to enter readily thru the rectal sphincter muscle, said insert comprising a water swellable polymer having a water content of at least 35% by weight, said insert having previously been frozen by being subjected to a temperature below 0° C. for a sufficient amount of time to freeze the free water therein and maintaining said insert with at least a portion thereof outside the sphincter muscle for at least one minute.
Claim 15
Dependent Claim
67 words
A method of claim 12 which comprises inserting into the rectum of the subject affected by hemorrhoids a substantially cylindrical device having a substantially conical nose end for insertion and a collar means having a diameter substantially greater than the maximum diameter of the nose portion located proximate to the rear end of the insert to prevent the passage of the entire insert through the sphincter muscle.
Claim 16
Dependent Claim
18 words
A method in accordance with claim 12 wherein the device comprises at least 90% by weight of water.
Claim 17
Dependent Claim
18 words
A method in accordance with claim 14 wherein the insert comprises at least 98% by weight of water.
Claim 18
Dependent Claim
27 words
A method in accordance with claim 12 wherein the insert comprises a multiblock copolymer of acrylonitrile acrylamide having a water content of 95 to 99.7% of water.
