Abstract
A catheter comprising, an elongated shaft having a main lumen, an inflation lumen extending along the shaft, and an outer surface. The catheter has an annular sleeve of elastic material joined to the shaft in spaced first and second circumferential zones defining a cavity intermediate the sleeve and shaft. The inflation lumen communicates with the cavity to inflate the sleeve, and the sleeve has an inner surface facing toward the outer surface of the shaft. The inner surface of the sleeve is separated from the outer surface of the shaft in spaced areas intermediate the first and second zones, with the sleeve being permitted to contact the shaft in regions intermediate the areas.
