Abstract
A stopple for retaining material within a hollow needle/push rod assembly is made of a synthetic absorbable material and is configured to fit snugly within the hollow needle of the needle/push rod assembly. The stopple is typically circular in shape, having a diameter that is substantially similar to the inner diameter of the hollow needle. The stopple prevents inadvertent ejection of material stored in the hollow needle/push rod assembly.
