Prostate Implant Delivery With Irrigation and Real-Time Visualization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for Benign Prostatic Hyperplasia (BPH) are only partially effective and burdened with significant side effects, and there is a need for new devices and methods to alleviate pressure on the prostatic urethra by compressing the prostate gland.
Innovation Solution
Deployment of anchor assemblies or implants into the prostatic tissue, combined with visualization and irrigation systems, to compress the prostate gland and relieve pressure on the urethra, using devices that allow for real-time visualization and irrigation during the treatment procedure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current treatments for BPH are used, then some symptom relief may be achieved, but significant side effects occur and effectiveness is only partial
Solution Approach 1:
The invention extracts and removes the enlarged prostatic tissue that is compressing the urethra through mechanical compression devices and anchor assemblies, eliminating the source of both symptoms and side effects associated with traditional treatments
Solution Approach 2:
The patent introduces intermediary devices including compression elements, anchor assemblies, and tissue repositioning mechanisms that mediate between the enlarged prostate and the urethra, relieving compression without direct tissue removal or chemical intervention
2Productivity
If the prostate gland is compressed to relieve urethral pressure, then urinary flow improves, but procedural complexity increases
Solution Approach 1:
The compression device is segmented into multiple independent components including delivery catheter, compression elements, anchor assemblies, and repositioning mechanisms, allowing staged deployment and simplifying the overall procedural complexity
Solution Approach 2:
The invention employs dynamic compression elements that can be adjusted and repositioned during the procedure, allowing optimization of compressive force and distribution based on real-time anatomical conditions
3Measurement precision
If visualization systems are added to improve procedural visibility, then treatment precision increases, but device complexity increases
Solution Approach 1:
The visualization system is merged with the delivery catheter and compression device, integrating imaging capabilities directly into the treatment instrument to reduce the number of separate components and simplify the overall system
Solution Approach 2:
The delivery device serves multiple functions including tissue visualization, compression application, anchor deployment, and repositioning, reducing the need for separate specialized instruments

AI summary
Implant delivery systems are configured to deploy implants into targeted tissue within a patient. The targeted tissue includes at least a portion of a prostate gland, and the implants are configured to compress or retract the tissue. Implant delivery systems include handheld components. Irrigation systems control fluid inflow and outflow at the treatment site. Sheath devices deliver irrigant to a treatment site within a patient, and elongate shaft devices remove contaminated irrigant, blood, and debris. Visualization systems provide an unobstructed view of the treatment site during implant deployment.
