Apparatus and method for infusing fluid through the sheath of a stone basket
First Claim
1. A stone basket, comprising:
- a sheath having forward and rearward ends and a longitudinal passageway;
a handle;
a connector fixedly attached to said rearward end of said sheath and releasably attached to said handle;
a basket assembly having at least a portion thereof disposed within said longitudinal passageway of said sheath, said basket assembly comprising a basket, said basket assembly being extensible beyond said forward end of said sheath to permit said basket to expand, and said basket assembly being removable from said longitudinal passageway of said sheath through said rearward end of said sheath; and
means for coupling a syringe to said connector when said connector is detached from said handle and said basket assembly is removed from said sheath for infusing fluid through said sheath;
whereby said handle can be detached from said connector, said basket assembly removed from said sheath, and a syringe coupled to said connector to infuse fluid through said sheath.

Abstract
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.
