摘要:
A catheter and a method of using a catheter for delivery of fluid, in particular a medicament, to the bladder of a patient. In one embodiment the catheter comprises a valve at its proximal end, the valve being arranged to prevent egress of fluid from the lumen via an aperture in the proximal end of the catheter. The valve allows passage of a fluid through the aperture and into the lumen of the catheter, but prevents egress of fluid from the lumen. In another embodiment the catheter comprises a tube having two portions of differing flexibility. The distal portion of the tube has less flexibility relative to the proximal portion of the tube. The relative stiffness of the distal portion facilitates easy insertion of the catheter into the urethra. The relatively flexible proximal portion protrudes beyond the urethral meatus and facilitates handling of this portion of the catheter.
