Modified veress needle for use in peritoneal dialysis catheter insertion |
| abstract |
A Veress needle assembly for a peritoneal dialysis catheter guide wire has (i) a hollow needle with a pointed end, (ii) an inner tube received within the hollow needle so as to be slidable relative to the hollow needle in the longitudinal direction between a first position in which the first end of the inner tube protrudes longitudinally beyond the pointed end of the hollow needle and a second position in which the first end of the inner tube is retracted so that the pointed end is unobstructed by the inner tube, and (iii) a biasing mechanism to bias the inner tube towards the first position. The inner tube includes a fluid passage having an outlet opening at the first end of the inner tube that is oriented to allow the peritoneal dialysis catheter guide wire to readily the outlet opening when inserted through the fluid passage of the inner tube. |
