This invention relates to microfabricated surgical devices and methods of making the same. One such device includes an end portion and a body portion wherein at least a part of the body portion is hollow and includes a conformally coated polymer formed on inside and outside surfaces of the body portion. One such method includes defining at least one channel in the surface of a first substrate, joining a second substrate to the first substrate to cover the channel, forming a trench in the first and second substrates on each side of the channel to define a shell structure, and releasing the shell structure from the first and second substrates. |
