HYBRID MOLD FOR A CATHETER BALLOON AND METHOD OF MANUFACTURING SUCH A BALLOON

摘要

A mold (100) for forming a balloon of a balloon catheter including a body- portion (104) defining a body region of a mold cavity (102) and distal (108) and proximal (110) end caps defining tapering regions of the mold cavity. During the molding process, the mold cavity (102) is visible from an exterior surface (106) of the body portion, which is transparent or translucent. The distal and proximal end caps are metal and can be precision machined in the tapering and neck regions of the mold cavity in order to achieve more accurate molded balloon dimensions. Also disclosed is a method for making a balloon of a balloon catheter using the mold and a balloon made therefrom.
