An expandable polymeric medical article is formed by a novel dip-molding process,ninvolving multiple dipping and rotational drying of liquid polymeric material layer atndifferent pivotal positions. Preferably, the rotational drying is conducted so as to form annexpandable polymeric medical article having a reverse thickness gradient in relation to thenthickness gradient of conventional dip-molded polymeric medical articles. Specifically, thenexpandable polymeric medical article of the present invention has an expandable bodynmember and a neck member, wherein such neck member has a wall thickness that is greaternthan that of the expandable body member, before any significant expansion of such bodynmember. |
