Brief Summary:
To assess the ability of the Silq ClearTract™ 100% Silicone 2-Way Foley Catheter to reduce biofilm formation in subjects that require a long-term indwelling Foley catheter when compared to other commercially available urinary catheters.

Condition or disease Intervention/treatment Phase
Biofilm Formation UTI Device: Long-term indwelling Foley catheter Not Applicable

Detailed Description:

A prospective, randomized, multi-center, post-market study in subjects that require a long-term indwelling Foley catheter.

A randomly assigned catheter will be inserted using standard techniques. Non-surgical subjects will rate the level of pain associated with the insertion procedure using the visual analog scale (VAS). A urine sample will be collected immediately after catheter insertion, in order to generate a baseline urinalysis and urine culture.

Follow-up visits will be performed on Day 28, or upon catheter removal, whichever occurs first. The catheter will be removed on Day 28 or earlier if clinically indicated. The removed catheter will be processed and sent to the core laboratory for analysis. Urine will be collected immediately prior to catheter removal in order to conduct urinalysis and urine culture. Subject will rate level of pain associated with the removal procedure using the VAS. The subject will also fill out a questionnaire about their experience with the catheterization immediately after catheter removal. Subjects will then be exited from the study.

Estimated Study Completion Date : May 2023

Arm Intervention/treatment
Active Comparator: Silq ClearTract™ 100% Silicone 2-Way Foley Catheter
Up to 82 subjects
Device: Long-term indwelling Foley catheter
Foley Catheter inserted for up to 28-days

Active Comparator: Silver-coated Latex 2-Way Foley Catheter
Up to 82 subjects
Device: Long-term indwelling Foley catheter
Foley Catheter inserted for up to 28-days

Active Comparator: Silicone-coated Latex 2-Way Foley catheter
Up to 82 subjects
Device: Long-term indwelling Foley catheter
Foley Catheter inserted for up to 28-days

Primary Outcome Measures :
  1. Biofilm formation [ Time Frame: 5 to 7 days ]
    A core lab will use the BacTiter-Glo Microbial Cell Viability Assay, a well characterized method for quantifying active biomass and biofilm, to determine biofilm formation on explanted catheter samples.
