Abstract

1313347 Method of making balloon catheters DAVOL Inc 2 July 1970 32209/70 Heading A5R A method of manufacturing a balloon-type catheter comprises the steps of forming a catheter shaft 10, preferably of plastics material, having a drainage lumen 14 and an inflation lumen 16 and an eye 20 formed through the wall of the shaft to communicate with the inflation lumen, placing a gel coating (22), Fig. 2 (not shown) around the shaft 10 in the neighbourhood of the said eye 20, overdipping the said coating and adjacent parts of the shaft 10 in a solution of solid material dissolved in a liquid which is a non-solvent for said gel, and allowing this second coating to dry forming a skin 24, and decomposing the gel layer by drying, but at an elevated temperature. The gel consists of a gelling agent selected from the group consisting of: a water soluble resin, methyl cellulose, colloidal alumina and aluminium stearate and the solvent, or dispersion agent for the gel from the group: water, toluene, an alcohol and methylene chloride. In order that the gel has a suitable viscosity, it is stated that the pH of the solution should be about 7 and to this end,. an alkali is either incorporated in the solution itself or in the overdipping solution.
