Abstract

1284701 Balloon catheter AMERICAN HOSPITAL SUPPLY CORP 20 April 1971 [20 April 1970] 10256/71 Heading A5R A balloon catheter comprises a plastics tube 10 having a balloon inflation lumen 12 therein, a balloon 35 and a pair of rigid ferrules 20, 21 indented in the outer surface of said tube, with bindings 40 securing said balloon to said ferrules. A method of making a balloon catheter illustrated in Figs, 1-5 (not shown) is characterized by the steps of providing a catheter tube (10) of thermoplastics material which has a "memory characteristic' (defined in the specification as a material which may be deformed if heated and stressed, but which will return to its original form if reheated when unconstrained) which contains a balloon inflation lumen; applying heat to an end portion of the tube sufficient to soften the material; drawing out and elongating the softened portion to shrink its diameter; applying a pair of rigid ferrules (20), (21) over the shrunken portion; applying heat to the latter to re-expand its diameter and lock the ferrules on the tube; forming a balloon inflation opening 33 in the material communicating with the balloon inflation lumen; applying a sleeve of elastic balloon material over the re-expanded portion; and binding the balloon material to said ferrules. The catheter tube may be formed from P.V.C. by extrusion and may contain a through lumen 11 in addition to the balloon inflation lumen 12. The distal end of the balloon inflation lumen may be plugged with a cylindrical plug 26 of P.V.C. and the distal tip of the catheter then shaped by a heated die. An alternative embodiment Fig. 9, (not shown) has the distal end of the balloon material everted under the windings so that when inflated the balloon is of such a shape as to prevent the point of the catheter touching the walls of the blood vessel through which the catheter is fed.
