An epidural needle has an elongate tube defining a longitudinal axis having a proximal end, a distal end and an axial hollow bore having an inside diameter therethrough. The needle has a hub with a proximal end, a distal end and an open passageway having an inside diameter substantially similar to the hollow bore therethrough, the distal end of the hub being fixedly attached to the proximal end of the elongate tube so that the hollow bore of the elongate tube is in fluid communication and substantial axial alignment with the open passageway. The hub further has a cavity disposed between the proximal end and the distal end of the hub. There is a resilient member with an opening therethrough that has an inner diameter substantially similar to the inside diameter of the hollow bore disposed in the cavity so that the opening is substantially axially aligned and in fluid communication with the open passageway. The hub of the epidural needle of the invention has a clamp with a releasable latch disposed about the resilient member. The clamp is selectively movable between an open position wherein the inner diameter of the resilient member is substantially unaffected, a clamp position wherein the clamp causes a strain to the resilient member and thereby reduces the inner diameter of the opening through the resilient member. The clamp also has a latch position where the latch releasably retains the clamp in the clamp position.

Variable extension combined spinal/epidural needle set and method for its use

A fluid transfer device for accessing fluid from vials and ampoules includes a cannula assembly that defines an axis. The cannula assembly includes a cannula with a proximal end, a distal end and a lumen therethrough. The cannula assembly also has a hub fixedly attached to the proximal end of the cannula that has an open proximal end in fluid communication with the lumen. The fluid transfer device has a filling straw with a proximal end, a distal end and a passageway therethrough and a housing with an outside surface that is fixedly attached to the proximal end of the straw. The housing has a cavity therein to coaxially receive at least a portion of the cannula assembly to form a fluid path between the open proximal end of the hub and the distal end of the filling straw. The fluid transfer device also has a removable shield with an open proximal end, a distal end, an outside surface, and a sidewall that defines a receptacle therein. The shield is rotatable with respect to the housing from a first position wherein the shield is removable from the housing to expose the filling straw for use and a locked position wherein the shield and the housing are locked together to form a unitary structure removable from hub to expose the cannula. The outside surface of the housing and the outside surface of the shield include an indication of the shield's rotational position with respect to the housing.
