Prostate Catheter with Radial Outflow Openings for Bleeding Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current prostate surgery and treatment catheters face challenges such as tissue cutting, bleeding, and intravascular injection risks due to standard cutting needles, and they do not effectively manage blood flow and cooling during procedures like transurethral resection of the prostate (TURP) surgery.
Innovation Solution
A catheter system with a needle featuring radial outflow openings and markings for precise positioning, minimizing tissue cutting and bleeding, and using anesthetic and antibiotic agents like adrenaline to suppress blood flow and cooling, allowing for efficient diffusion and reduced perioperative bleeding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a standard cutting needle is used for prostate treatment, then tissue penetration is achieved, but tissue cutting and bleeding occur
Solution Approach 1:
The needle is designed with multiple radial outflow openings that create a porous injection pattern, allowing fluid to diffuse through the tissue without requiring a cutting tip. This porous injection approach enables tissue penetration while minimizing tissue cutting and bleeding by distributing the injection force across multiple openings rather than concentrating it at a single cutting edge.
Solution Approach 2:
The needle is segmented into multiple functional zones with radial outflow openings distributed around the needle shaft. This segmentation allows the injection force to be distributed across multiple points, enabling effective tissue penetration while reducing localized tissue damage and bleeding compared to a single cutting tip design.
2Ease of operation
If a standard cutting needle is used, then injection can be performed, but intravascular injection risk increases
Solution Approach 1:
The radial outflow openings create a porous injection pattern that distributes the injected fluid across a wider tissue area, reducing the likelihood of intravascular injection. The distributed injection pattern allows the fluid to penetrate through the tissue barrier more reliably without concentrating force at a single point that could inadvertently enter a blood vessel.
3Reliability
If blood flow is not suppressed, then normal prostate function is maintained, but bleeding occurs during TURP surgery
Solution Approach 1:
The catheter system allows for preliminary injection of vasoconstrictive agents through the radial outflow openings before the TURP surgery begins. This preliminary action suppresses blood flow to the prostate tissue in advance, reducing bleeding during the surgery while maintaining normal prostate function through controlled, distributed injection rather than abrupt intervention.
Solution Approach 2:
The porous injection pattern created by radial outflow openings allows for distributed delivery of vasoconstrictive agents throughout the prostate tissue. This distributed approach ensures comprehensive blood flow suppression while maintaining control over the injection process, preventing excessive bleeding during TURP surgery.
4Temperature
If cooling is not applied, then normal tissue temperature is maintained, but tissue damage increases during heat treatment
Solution Approach 1:
The catheter system enables preliminary cooling of the prostate tissue through the radial outflow openings before heat treatment begins. This preliminary cooling action creates a temperature gradient that protects the tissue from thermal damage during subsequent heat treatment, while the distributed injection pattern ensures even cooling across the entire prostate surface.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The catheter system reduces tissue damage, minimizes bleeding, and enhances anesthesia and treatment efficacy by allowing precise injection of agents at multiple prostate positions, improving surgical outcomes and reducing blood loss during procedures like TURP.
Implementation Method 1
filling of the balloon stopper unit with a fluid is intended when the balloon stopper unit is arranged inside of the bladder of a patient to provide for a stopper function of the balloon stopper unit against the bladder neck of the patient
Implementation Method 2
injecting at least one anesthetic agent and/or antibiotic agent to the prostate via the injection tube and said at least one outflow opening of the needle at an intended position of the prostate
Implementation Method 3
using anesthetic and antibiotic agents like adrenaline to suppress blood flow and cooling
