INFLATABLE BALLOON (VERSIONS) Russian patent published in 2006 - IPC A61M25/10 

FIELD: medical equipment.

SUBSTANCE: inflatable balloon can be used for making catheters which have carrier axial polymer tube with inflatable working medium through hole in wall of tube by balloon dispose at one end and with valve unit for keeping working medium, disposed at the other end. Device is intended for curing detachment of retina by means of blocking rupture of retina under effect of wave of impression generated by inflated balloon. Inflatable balloon has end tubular taps for fastening to carrier axial tube and central inflatable part, which can take shape of sphere, or ellipse either cylinder of the balloon. Walls of balloon are made of three layers of internal and external layers of silicon rubber to have intermediate layer of polyorganosiloxane. Walls are made of three layers of internal and external layers of silicon rubber to have intermediate layer of polyorganosiloxane. According to the second version, tubular sections of silicon rubber are disposed concentrically onto surface of ends of inflatable part; the sections are integrated with the surface of tube. The sections are made for widening at balloon's bulge.

EFFECT: improved mechanical strength; reduced gas permeability.
