And catheter with a suction function, system and associated method for obtaining a biological sample in vivo

摘要

And the method comprising the step of positioning the prostatic urethra of a subject (10) an elongated transurethral catheter, methods for treating a subject and / or available in vivo sample, system, computer program product, the catheter (10 biological sample entry port biological sample entry port and one (25), is retained catheter (10) at least inside were spaced apart in the axial direction bladder fixing balloon (15), bladder fixing balloon from (15)) and a biological sample flow path extending in the axial direction and in fluid communication (25). Inflatable (15) for fixing balloon, fluid entry port is located in the prostatic urethra near the subject, via (25) biological sample entry port from the prostatic urethra biological sample flow path fluid of the prostate (25c I positioned the catheter (10) to be sucked into). The samples which contained (20) the dilation balloon and / or thermal treatment balloon (20) and suction, at the same time as in the treatment, the treatment being carried out, or catheter (10) is obtained in the time close to the treatment delivery. (10) can be configured in a state of being separated from the urine prostatic fluid sample collected, to be able to urinate through a catheter in the treatment / sample collection during catheter.
