The invention provides a rapid exchange
catheter device that can be used for
thrombolysis in coronary
artery thrombus and can be used for
percutaneous transluminal coronary
angioplasty (PTCA). The device includes a guide wire tube, an inner tube , outer tube and
balloon; the middle and distal section of the wire
guide tube, the inner tube and the outer tube are coaxially invaginated from the inside to the outside; It opens in the inner cavity of the inner tube; the inner cavity of the inner tube is a connected
perfusion cavity, and its proximal end is provided with a
drug injection port, and its far part is provided with
perfusion side holes and guide wire inlets that open in multiple directions; the outer tube and the inner tube The space between them is the
balloon pressure-reduction cavity, the proximal end is provided with the
balloon pressure-reduction hole, and the distal end communicates with the balloon cavity. The present invention integrates the functions of the thrombolytic
catheter and the
balloon catheter into one
catheter, can quickly complete the two operations of
thrombolysis and PTCA in coronary
thrombosis, can reduce the
thrombus load, prevent thromboembolism, shorten the
operation time, and reduce the number of doctors and doctors. X-
ray exposure of the patient.
