Stopcock
First Claim
1. A stopcock comprisinga tubular body having a first radial opening and a second radial opening, the radial openings being spaced apart circumferentially and being located in a common plane orthogonal to an axis of the tubular body, and the second radial opening having a diameter larger than the first radial opening;
- a hollow core member snugly received within the tubular body for rotation about the axis of the tubular body, the core member defining a lumen having an open end and a closed end, the core member having at least one radial bore located in the common plane of the radial openings in the tubular body and in communication with the lumen, and the lumen and a first bore of the at least one radial bore of the core member having diameters not less than the diameter of the second radial opening of the body; and
handle means affixed to the core member adjacent the closed end of the lumen for rotating the core member between a first position in which a radial bore is in register with the first radial opening and a second position in which said first bore of the at least one radial bore is in register with the second radial opening.

Abstract
A stopcock comprises a tubular outer body having at least two radial openings being on the same transverse cross-sectional plane of said body; and a hollow core member snugly fitting into said outer body and having a first open end and a second, closed end, said member being connected to or integral with a handle at said second end; said member having at least one radial bore; and being rotatable within said body between a first state in which said bore is in register with a first of said at least two openings and a second state in which said bore is in register with a second of said at least two openings.
