AI Technical Summary

Technical Problem

Current urinary catheters cause physical trauma to the bladder, increase the risk of catheter-associated urinary tract infections (CAUTIs), and suffer from residual urine accumulation due to high drainage ports or obstruction by the catheter tip, leading to bacterial growth and crystalline deposits.

Method used

A urinary catheter design featuring a split tip with an expandable balloon that separates into two or more parts, exposing a horizontal drainage opening perpendicular to the urine flow, secured by balloon elements that act as retaining elements, preventing tip exposure and residual urine.

Benefits of technology

Prevents bladder damage, reduces infection risk, and ensures consistent urine drainage by maintaining an open horizontal passage, mimicking natural urethra functionality and reducing residual urine accumulation.

Abstract

The present invention discloses a urinary catheter that utilizes a balloon to create a way for urination. The disclosed invention does not implement a traditional drainage port and avoids an exposed catheter tip. Rather, the invention comprises a multi-lumen shaft with split tips that when separated create a horizontal opening for urine drainage. The invention utilizes a retention member that can take the form of multiple expandable balloons or a single expandable central balloon. The balloon elements can comprise balloons separately attached to each split tip or one balloon shared with adjacent split tips, such that when the balloon elements expand, a communicating channel appears between the bladder and the central lumen of the shaft, ultimately creating a way for urination.
