ABSTRACT:
The cyst puncture catheter assembly comprises: a catheter having a distal portion, a central lumen, an open distal end and a smaller-in-diameter distal end lumen between the central lumen and the open distal end; and, at least one stylet sized to fit within the catheter distal portion. The stylet comprises an elongate shaft having a distal end and a shoulder extending radially outwardly from the shaft at a location close to the stylet distal end. The distal portion of the catheter has an annular shoulder in the central lumen between the central lumen and the smaller-in-diameter lumen against which the shoulder on the stylet can seat so that the stylet and the catheter can be inserted together through tissue to a location of a cyst without the catheter moving longitudinally relative to the stylet.
