ABSTRACT:
A seal having a body and several bands extending away from the body. The bands extend around an axial portion of the body. In some embodiments, the bands project from and are formed integral with the body. For example, the bands can be rings. Two bands can be located on the outside of the body and two additional bands can be located on the inside of the body to provide redundant sealing components between separated fluids. A vent aperture can be positioned between the two bands on each side of the body. The two inner bands can be offset from the two outer bands. The seal can be used in a surgical cutting device, among other things.
