Abstract

Abstract A colonic endoprosthesis includes a tubular jacket element which consists of two tubular members which are telescopically received within one another and arrested in a telescoped position thereof when the tubular jacket element is implanted in the body of a user. A container element consisting of a hollow support member and an elastic lining member received in the hollow support member is removably insertable into the jacket element and retained in the fully inserted position thereof. The distal end of the intestinal tract of a user is connected to and communicates with the colonic endoprosthesis for the digested matter to enter and accummulate in the elastic lining member mounted on the support member of the container element until the time for emptying the hollow support member. Both the jacket element and the container element may be straight, or they may assume an S-shaped configuration when implanted and inserted so as to conform to the natural course of the original distal end of the intestinal track of the user. A connecting frame mounts the implanted jacket element in the pelvic basin of the user so that a distal end of the jacket element is situated at the location of the original anal sphincter.

Claims Analysis

Total Claims: 20
Claim 1
Independent Claim 161 words
A colonic endoprosthesis comprising an elongated tubular jacket element adapted to be planted in the body of the user and having one end portion and another end portion spaced from said one end portion; a container element removably insertable into said jacket element so as to be located in the body of the user, said container element including a hollow support member and an elastic lining member mounted on and received in said hollow support member; means for retaining said container element in a fully inserted position thereof relative to said jacket element; a first connecting formation on said one end portion of said jacket element for connecting the latter to the distal end of the intestenal tract of the user; and a second connecting formation on said other end portion of said jacket element for connecting the same to the skin of the user so that feces or partially digested food are removed from the body through the colonic endoprosthesis.
Claim 2
Dependent Claim 161 words
A colonic endoprosthesis comprising an elongated tubular jacket element adapted to be planted in the body of the user and having one end portion and another end portion spaced from said one end portion; a container element removably insertable into said jacket element so as to be located in the body of the user, said container element including a hollow support member and an elastic lining member mounted on and received in said hollow support member; means for retaining said container element in a fully inserted position thereof relative to said jacket element; a first connecting formation on said one end portion of said jacket element for connecting the latter to the distal end of the intestenal tract of the user; and a second connecting formation on said other end portion of said jacket element for connecting the same to the skin of the user so that feces or partially digested food are removed from the body through the colonic endoprosthesis.
Claim 3
Dependent Claim 47 words
A colonic endoprosthesis as defined in claim 1, wherein said jacket element includes an outer tubular member, an inner tubular member telescopically received in said outer tubular member, and means for arresting said inner tubular member in a predetermined telescoped position relative to said outer tubular member.
Claim 4
Dependent Claim 57 words
A colonic endorpsothesis as defined in claim 2, wherein said first connecting formation further includes an inlet funnel communicating the distal end of the intestinal tract of the user with, and converging toward said container element, said funnel being separate from said outer tubular member and preventing feces from entering between said inner and outer tubular members.
Claim 5
Dependent Claim 16 words
A colonic endoprosthesis as defined in claim 1, wherein said jacket element is elongated and rigid.
Claim 6
Dependent Claim 44 words
A colonic endoprosthesis as defined in claim 4, wherein said jacket element has a straight longitudinal axis; and wherein said support member is also elongated and has a longitudinal axis which coincides with said axis of said jacket element in said fully inserted position.
Claim 7
Dependent Claim 14 words
A colonic endoprosthesis as defined in claim 5, wherein said support member is rigid.
Claim 8
Dependent Claim 25 words
A colonic endoprosthesis as defined in claim 1, wherein said jacket element is elastically yieldable for the implanted jacket element to assume said S-shaped configuration.
Claim 9
Dependent Claim 19 words
A colonic endoprosthesis as defined in claim 1, wherein said retaining means includes a threaded connection between said elements.
Claim 10
Dependent Claim 31 words
A colonic endoprosthesis as defined in claim 1, wherein said retaining means includes complementary projections and recesses on said elements which engage one another at least in said fully inserted position.
Claim 11
Dependent Claim 34 words
A colonic endoprosthesis as defined in claim 1, and further comprising means for removing said container element from said jacket element, including at least one projection on a distal end of said container element.
Claim 12
Dependent Claim 20 words
A colonic endoprosthesis as defined in claim 1; and further comprising a container element removably insertable into said jacket element.
Claim 13
Dependent Claim 27 words
A colonic endoprosthesis as defined in claim 1, wherein said container has two opposite open ends, and means for detachably closing one open end of said container.
Claim 14
Dependent Claim 38 words
A colonic endoprosthesis as defined in claim 12, wherein said closing means include a plug readily removable from said one end of said container to thereby permit access to the interior of the container from the outside thereof.
Claim 15
Dependent Claim 27 words
A colonic endoprosthesis as defined in claim 1, wherein said first connecting formation includes an annular flange arranged at said one end portion of said jacket element.
Claim 16
