Flexible intraosseous obturator

Abstract

Apparatus and methods of manufacture for an intraosseous assembly. The intraosseous assembly includes a flexible obturator with relatively low columnar strength, relatively low shear strength, and/or relatively high compressive strength. When the flexible obturator is supported in a needle of the intraosseous assembly, it can prevent bone fragments and tissue from blocking the needle lumen. When removed from the needle, the flexible obturator can deform under a force to prevent accidental needle stick injuries. The flexible obturator can define a radially symmetrical profile and can conform to the inner profile of the needle lumen. The flexible obturator can extend beyond a distal tip of the needle and be trimmed flush to a beveled surface of the needle. This simplifies the manufacturing process, allowing a single size obturator to be fitted to multiple sizes of needle.
