Medical Procedure Kit and Methods for Draining Fluid from an Organ

Abstract

Embodiments include methods for draining fluids from a body organ, such as pericardiocentesis. Embodiments include inserting a large diameter outer needle through the chest wall towards an organ, inserting a smaller diameter microneedle through the outer needle and into the organ, threading a microwire through the lumen of the inner microneedle into the organ, removing the outer needle and inner microneedle, threading a guide sheath over the microwire into the organ, removing the inner dilator and microwire from the guide sheath, inserting a stiffer guide wire through the guide sheath into the organ, removing the guide sheath, threading a drain sheath over the stiffer guide wire into the organ, removing the stiffer guide wire, securing the drain sheath to the patient using a stay fix device, and connecting a suction device to the proximal end of the drain sheath and creating negative pressure to facilitate fluid drainage.
