Abstract
Abstract A catheter for a morphological duct is disclosed, comprising an inflatable sleeve surrounding the distal end of said catheter and connected to the proximal end of said catheter by at least one inflating conduit which can be connected to an inflating device and said inflatable sleeve may take on either a deflated state in which it is applied against said distal end of said catheter, or an inflated state in which it is applied by its external wall against the internal wall of said morphological duct, then forming an annular space between its internal wall and said distal end of said catheter.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
148 words
Catheter for a morphological duct comprising an inflatable sleeve having an external wall and an internal wall, said sleeve surrounding the distal end of said catheter and connected thereto by a first flexible connection, said first flexible connection being itself connected to the proximal end of said catheter by at least one inflating conduit which can be connected to an inflating device and said inflatable sleeve may take on either a deflated state in which its internal wall is applied against said distal end of said catheter, or an inflated state in which its external wall bears against the internal wall of said morphological duct, forming an annular space between the internal wall of said inflatable sleeve and said distal end of said catheter, wherein said inflating device feeds inflating fluid capable of making said sleeve rigid in its inflated state and said first flexible connection is breakable.
Claim 2
Dependent Claim
148 words
Catheter for a morphological duct comprising an inflatable sleeve having an external wall and an internal wall, said sleeve surrounding the distal end of said catheter and connected thereto by a first flexible connection, said first flexible connection being itself connected to the proximal end of said catheter by at least one inflating conduit which can be connected to an inflating device and said inflatable sleeve may take on either a deflated state in which its internal wall is applied against said distal end of said catheter, or an inflated state in which its external wall bears against the internal wall of said morphological duct, forming an annular space between the internal wall of said inflatable sleeve and said distal end of said catheter, wherein said inflating device feeds inflating fluid capable of making said sleeve rigid in its inflated state and said first flexible connection is breakable.
Claim 3
Dependent Claim
25 words
The catheter as claimed in claim 1, further comprising a resilient membrane surrounding said sleeve and compressing its against said distal end of the catheter.
Claim 4
Dependent Claim
13 words
The catheter as claimed in claim 2, wherein said resilient membrane is perforated.
Claim 5
Dependent Claim
46 words
The catheter as claimed in claim 1, further comprising a draining conduit connecting said sleeve to the proximal end of the catheter, by means of a second flexible connection connecting said sleeve to the distal end of said catheter, wherein said second flexible connection is breakable.
Claim 6
Dependent Claim
20 words
The catheter as claimed in claim 1, wherein said sleeve is formed by a tube wound in a helical coil.
Claim 7
Dependent Claim
16 words
The catheter as claimed in claim 5, wherein the turns of said coil are not jointing.
Claim 8
Dependent Claim
14 words
The catheter as claimed in claim 1, wherein said sleeve is a double-walled tube.
Claim 9
Dependent Claim
29 words
The catheter as claimed in claim 7, wherein said double-walled tube is formed with lateral openings which are sealed against entry of fluid to the interior of said tube.
Claim 10
Dependent Claim
12 words
The catheter as claimed in claim 1, wherein said sleeve is pre-formed.
Claim 11
Dependent Claim
38 words
The catheter as claimed in claim 9, wherein the external diameter of said sleeve, inflated out of said morphological duct to the pressure of use thereinside, is greater by about 10% than the diameter of said morphological duct.
