The invention provides a pressure sensing catheter having a housing with a body portion adapted to be hand-held, a pressure sensing means situated within the catheter housing and an elongated catheter tube with a lumen extending longitudinally therethrough. The pressure sensing means has a pressure sensor element, a microprocessor and a display means located on the top surface of the catheter housing. The invention also provides a pressure sensing catheter with a steering means ergonomically adapted in a pistol-grip fashion with digitally depressible steering posts connected to steering wires for manipulating the distal end of the catheter tube. The invention also provides a pressure sensing catheter with helically braided support wires disposed along selective portions of the catheter tubing to provide differential flexibility. The invention also provided methods of using the same.
