Abstract
A device having a sheath, a medical device, a stylet, a handle and a plunger device. The handle includes portions connected proximal ends of the sheath, the medical device and the stylet and a chamber portion connected to the actuator. The chamber portion includes a volume of space configured to volumetrically connect to at a lumen of the medical device, the sheath or the stylet and a plunger device configured to be slidably received within the chamber portion. The plunger device is able to pneumatically isolate a proximal portion of the volume of space from a distal portion of the volume of space. Proximal movement of the stylet and the plunger device cause a suction effect (i.e., reduced pressure) at the distal end of the sheath, the medical device and/or the stylet.
