Urinary probe for post-operative use after prostate gland surgery - comprises elongate probe body with inflatable balloon shaped to correspond to prostate shape on inflation, positioning probe in ureter

摘要

An elongate tubular probe (1) is partially surrounded by an inflatable balloon (2) which is connected at the distal, exterior end of the probe to an inflating valve (4) via a conduit (5) attached to the probe body. The balloon is formed with a spinning-top shaped configuration corresponding to that of the prostatic chamber. The lower end (3) of the balloon includes a portion of increased wall thickness, extending around its entire circumference. The increased resistance to inflation of this portion defines the top-shaped configuration of the balloon on inflation. ADVANTAGE - Avoids risk of post-operative haemorrhage and infection of prostate gland.
