Abstract
A device having a sheath, a medical device, a stylet, a handle having a chamber portion and a plunger device. The handle connects to proximal ends of the sheath, the medical device, and the stylet. 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. The plunger device slides and moves within the chamber portion. The plunger device is able to pneumatically or hydraulically 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., negative or reduced pressure) at the distal end of the sheath and/or the medical device.
