Apparatus and method for infusing fluid through the sheath of a stone basket

摘要

An apparatus and method for infusing fluid through the sheath of a stone basket involves a connector fixedly attached to the rearward end of the sheath and releasably attached to a handle. A basket assembly has a portion thereof disposed within the longitudinal passageway of the sheath. The basket assembly is extensible beyond the forward end of the sheath to permit its basket to expand. The basket assembly is removable from the longitudinal passageway of the sheath by uncoupling the connector from the handle and withdrawing the basket assembly through the rearward end of the sheath. The connector further includes a means for coupling a syringe to the connector when the connector is detached from the handle and the basket assembly is removed from the sheath. Thus the handle can be detached from the connector, the basket assembly removed from the sheath, and a syringe coupled to the connector to infuse fluid through the sheath.
