Claim:
1. A method of removing a stone disposed within a salivary duct having a salivary duct opening, the method comprising the steps of: positioning a control handle on a medical device having a proximal end and a distal end; releasably attaching the control handle to the medical device; inserting the distal end of the medical device into a lumen defined by a scope having a proximal end and a distal end such that the distal end of the medical device is disposed distal to the distal end of the scope, the lumen of the scope extending between an opening at the proximal end of the scope and an opening at the distal end of the scope; inserting the distal end of the medical device through said salivary duct opening such that the distal end of the medical device is disposed distal to said salivary duct opening and in said salivary duct; inserting the distal end of the scope through said salivary duct opening such that the distal end of the scope is disposed distal to said salivary duct opening and in said salivary duct; navigating the distal end of the medical device through said salivary duct and towards a point of treatment; contacting the distal end of the medical device with said stone disposed in said salivary duct; performing treatment using the medical device; and withdrawing the medical device from said salivary duct; wherein the control handle comprises: a first portion having a proximal end, a distal end, a first shaft, a projection, and defining a recess and an aperture, the shaft extending from the proximal end towards the distal end of the first portion, the projection extending from a location between the proximal end and the distal end to the distal end of the first portion, the recess extending into the projection from the distal end of the first portion towards the proximal end of the first portion to a recess base, the aperture extending from a first opening defined on the proximal end of the first portion to a second opening defined on the recess base; a second portion having a proximal end, a distal end, a second shaft, and defining a recess and an aperture, the second shaft extending from the proximal end to the distal end of the second portion, the recess extending into the second shaft from the proximal end towards the distal end of the second portion to a recess base, the aperture extending from a first opening defined on the recess base of the second portion to a second opening defined on the distal end of the second portion; and a compressible member having a proximal end and a distal end; wherein a portion of the compressible member is disposed within one of the recess defined by the first portion or the recess defined by the second portion; wherein the first portion is adapted to be releasably attached to the second portion; wherein the projection is adapted to be received by the recess defined by the second portion; and wherein said control handle is moveable between a first configuration and a second configuration, in the first configuration the projection is free of the recess of the second portion, in the second configuration the projection is disposed within the recess of the second portion and the first portion is releasably attached to the second portion.
