A handle for receiving an elongate medical device is provided. The handle includes a housing defining an elongate hollow interior portion, the hollow portion defining a first portion proximate the distal end and the aperture, a second portion. A core is slidably disposed within the interior portion and includes a ramp portion extending from an outer surface of the core at an oblique angle to the longitudinal axis, and two or more arms extending outwardly from a proximal end of the core and biased toward an extended configuration where a proximal end of each arm extends radially outside of an outer surface of the core, wherein the two or more arms combine to define the proximal opening. A button is movably disposed within the aperture substantially blocking communication with the hollow portion through the aperture, comprising an inclined surface that slidably engages the ramp surface. |

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, an elongate outer sheath movably fixed to the housing, a portion of the outer sheath extends into the central hollow portion of the housing and a second portion of the outer sheath extends distally outside of the central hollow portion, the outer sheath comprising a sheath lumen that is aligned coaxially with the elongate core lumen, the sheath lumen is sized to receive a distal portion of the shaft of the elongate medical device when received within the core lumen. |
