Abstract
Abstract A device for removing undesirable material from a tubular structure within the human body features a cylindrical body with a lumen therethrough. The distal portion of the body is divided into a number of flexible members. An inflatable cuff is attached to the flexible members. When the cuff is inflated, the members flex radially outwardly so that the distal opening of the lumen is expanded. An inflation tube is used to inflate and deflate the cuff by means of a syringe. An elastomeric membrane sleeve surrounds the flexible members so that the latter are contracted towards their original position when the cuff is deflated. The sleeve also prevents material from escaping between the flexible members when the cuff is inflated.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
108 words
A device for retrieving material from tubular structures within the human body comprising: a) a cylindrical body defining a central lumen, the cylindrical body having a proximal portion and a distal portion, said distal portion being radially expandable and having an end with an opening; b) an inflatable cuff attached to said end of said distal portion, said cuff when inflated causing the distal portion to move radially outward to expand the diameter of the opening in the end of the distal portion; c) an inflation lumen in fluid communication with said inflatable cuff; and d) means for inflating and deflating said inflatable cuff through said inflation lumen.
Claim 2
Independent Claim
108 words
A device for retrieving material from tubular structures within the human body comprising: a) a cylindrical body defining a central lumen, the cylindrical body having a proximal portion and a distal portion, said distal portion being radially expandable and having an end with an opening; b) an inflatable cuff attached to said end of said distal portion, said cuff when inflated causing the distal portion to move radially outward to expand the diameter of the opening in the end of the distal portion; c) an inflation lumen in fluid communication with said inflatable cuff; and d) means for inflating and deflating said inflatable cuff through said inflation lumen.
Claim 3
Dependent Claim
23 words
The device of claim 1 wherein said distal portion of the cylindrical body includes a surface to which said inflatable cuff is attached.
Claim 4
Dependent Claim
14 words
The device of claim 2 wherein said inflation lumen is a cuff inflation tube.
Claim 5
Dependent Claim
23 words
The device of claim 3 wherein said cuff inflation tube is attached to the surface of the distal portion of the cylindrical body.
Claim 6
Dependent Claim
35 words
The device of claim 1 wherein said means for inflating and deflating said inflatable cuff includes a side port formed in the proximal portion of said cylindrical body and in communication with said inflation lumen.
Claim 7
Dependent Claim
24 words
The device of claim 5 wherein said means for inflating and deflating said inflatable cuff includes a syringe in communication with said side port.
Claim 8
Dependent Claim
40 words
The device of claim 1 wherein said distal portion includes a plurality of flexible members, said flexible members moving radially outwards so as to expand the opening of the end of the distal portion when said inflatable cuff is inflated.
Claim 9
Dependent Claim
31 words
The device of claim 7 wherein said plurality of flexible members are surrounded by an elastomeric membrane sleeve so that the members are drawn together when said inflatable cuff is deflated.
Claim 10
Dependent Claim
137 words
An expandable lumen device for retrieving matter from tubular structures within the human body comprising: a) a cylindrical body defining a central lumen with a distal opening, the cylindrical body having a proximal portion and a distal portion with said distal portion defined by a plurality of flexible members; b) an inflatable cuff attached to said plurality of flexible members so that when said inflatable cuff is inflated, the flexible members move radially outwardly so as to expand the distal opening of the central lumen; c) an elastomeric membrane sleeve surrounding the plurality of flexible members so that said plurality of flexible members are drawn together when said inflatable cuff is deflated; d) an inflation lumen in fluid communication with said inflatable cuff; and e) means for inflating and deflating said inflatable cuff through the inflation lumen.
Claim 11
Dependent Claim
137 words
An expandable lumen device for retrieving matter from tubular structures within the human body comprising: a) a cylindrical body defining a central lumen with a distal opening, the cylindrical body having a proximal portion and a distal portion with said distal portion defined by a plurality of flexible members; b) an inflatable cuff attached to said plurality of flexible members so that when said inflatable cuff is inflated, the flexible members move radially outwardly so as to expand the distal opening of the central lumen; c) an elastomeric membrane sleeve surrounding the plurality of flexible members so that said plurality of flexible members are drawn together when said inflatable cuff is deflated; d) an inflation lumen in fluid communication with said inflatable cuff; and e) means for inflating and deflating said inflatable cuff through the inflation lumen.
Claim 12
Dependent Claim
20 words
The expandable lumen device of claim 9 wherein said flexible members include surfaces to which said inflatable cuff is attached.
Claim 13
Dependent Claim
16 words
The expandable lumen device of claim 10 wherein the inflation lumen is a cuff inflation tube.
Claim 14
Dependent Claim
23 words
The expandable lumen device of claim 11 wherein said cuff inflation tube is attached to the surface of one of the flexible members.
Claim 15
Dependent Claim
37 words
The expandable lumen device of claim 9 wherein said means for inflating and deflating said inflatable cuff includes a side port formed in the proximal portion of said cylindrical body and in communication with said inflation lumen.
Claim 16
Dependent Claim
