Surgical balloon having varying wall thickness

A surgical balloon for insertion into a uterus, comprising:

• a substantially continuous outer wall defining an exterior surface of the balloon on a first side and an interior hollow of the balloon on a second side, the outer wall being formed from a stretchable elastic material and being stretchable by pressure within the inner hollow between a collapsed state and an expanded state;
• the substantially continuous outer wall having a base portion for coupling with a catheter, and a substantially hemispherical shaped end portion positioned at a distal end of the balloon and adjacent the first portion,
• wherein the end portion has a primary wall thickness less than a primary wall thickness of the base portion.
