ABSTRACT VACUUM CURET A vacuum curet of novel design having a central portion which is tapered and an internal lumen which is preferably also tapered. This provides a curet which is rigid over its central and proximal end (i.e. the end that fits into a vacuum source) and maxi- mal flexibility and small external diameter at its distal end portion. Further advantages of this arrange- ment are reducing the possibility of perforation (due to the flexibility of the distal end portion), better "feel" (due to the rigidity of the central and proximal end portion), and decreased trauma due to the thin wall thickness of the proximal end portion and a corres- ponding reduction in outside diameter for a given or required lumen diameter. The lumen of this design may also be mass produced. In an additional embodiment, there is a novel design on the tip openings at the distal end, which further minimizes the possibility of perfora- tion. 1.
