Abstract:
1. A handle for removably receiving an elongate medical device, comprising: an elongate rigid housing enclosing a central hollow portion disposed along at least a substantial portion of the housing and an aperture disposed upon a side surface of the housing communicating with the hollow portion, the hollow portion maintaining a first inner diameter for a majority of a length of the hollow portion, and a second smaller inner diameter portion at a proximal portion of the hollow portion; a slidable core disposed within the hollow portion of the housing, the slidable core comprising an elongate core lumen disposed therethrough, the core lumen sized to receive a shaft of an elongate medical device, the core further comprising a ramp surface disposed thereon; a collet disposed within the hollow portion and movable with movement of the core within the housing, the collet comprising a collet lumen in registration with the core lumen, and further comprising two or more arms attached to a proximal end of the collet at a first portion thereon and each with a second portion that is biased radially outward outside of an outer surface of the collet, wherein the slidable core and the collet are biased distally such that the second portion of each arm contacts the smaller diameter portion to urge each arm radially inward from its biased configuration toward a restrained configuration, wherein the arms each contribute to a rear opening into the collet lumen, wherein the motion of the arms radially outward increases a diameter of the rear opening, wherein the core lumen and the collet lumen are configured to slidably receive the shaft of an elongate medical device, such that a proximal end of the shaft extends through the rear opening, and further comprising an elongate portion of a medical device provided as a kit with the handle, the elongate portion comprising a proximal tip, and a transition portion connected distally of the proximal tip and formed with a smaller diameter than a diameter of the proximal tip, wherein the transition portion is configured to be received within the collet lumen, and the proximal tip extends through the rear opening.
