Abstract

Abstract A catheter for clinical use comprises a length of inflatable tubing which, towards the end to be inserted, is provided with an inflatable outer sleeve or balloon. Air or liquid may be fed to the balloon for inflation through a catheter tube or bore which runs along at least part of the length of the catheter tube wall. The catheter has an inflatable portion of tubing 14 which is normally pre-inflated and which is connected to the inflatable balloon, sealing means 18, 20 being provided for both ends of the inflatable portion, the inflatable portion being covered with a sleeve 16 of elastic material. In use and after insertion of the catheter a sealing means 18 is removed and the modulus of elasticity of the elastic sleeve causes the inflated sleeve to return to its original shape causing air or liquid previously in the inflatable portion to inflate the balloon at the inserted end of the catheter. <IMAGE>

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 43 words
A catheter of the type described having an inflatable portion of tubing forming part of, or attached to, the catheter tubing, sealing means being provided for both ends of the inflatable portion, the inflatable portion being covered with a sleeve of elastic matErial.
Claim 2
Dependent Claim 43 words
A catheter of the type described having an inflatable portion of tubing forming part of, or attached to, the catheter tubing, sealing means being provided for both ends of the inflatable portion, the inflatable portion being covered with a sleeve of elastic matErial.
Claim 3
Dependent Claim 30 words
A catheter as claimed in Claim 1 wherein the inflatable portion forms part of a branch extending from and connecting to the main catheter tube but being of smaller diameter.
Claim 4
Dependent Claim 36 words
