Scope-Guided Anchor Delivery for Minimally Invasive BPH Treatment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for Benign Prostatic Hyperplasia (BPH) are invasive, require general anesthesia, have high risks of adverse effects, and provide suboptimal results, with minimally invasive methods causing patient discomfort and prolonged recovery.
Innovation Solution
A delivery device that deploys multiple anchor assemblies from a single device, allowing precise implantation of anchors in the body to treat BPH, with mechanisms for efficient reloading and minimal patient discomfort, and includes a scope for procedural viewing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional surgical procedures (TURP, TVP, TUIP, laser prostatectomy) are used to treat BPH, then effective symptom relief is achieved, but general anesthesia and high risk of adverse effects are required
Solution Approach 1:
The patent replaces traditional mechanical surgical instruments with a minimally invasive delivery system that uses a scope and anchor-based mechanical compression mechanism. The system delivers treatment through a urethral catheter without requiring general anesthesia, using local anesthesia only, thereby reducing the harmful factors of anesthesia risk while maintaining effective symptom relief through controlled mechanical compression of the prostate.
Solution Approach 2:
The patent introduces an intermediary delivery system consisting of a scope and catheter assembly that mediates between the operator and the prostate tissue. This intermediary system allows precise delivery of compression forces through anchors embedded in the prostate capsule, enabling effective treatment while avoiding the need for general anesthesia and reducing adverse effects.
2Object-affected harmful factors
If minimally invasive procedures (TUMT, TUNA, ILC) are used to treat BPH, then anesthesia risk is reduced, but patient discomfort and prolonged recovery occur
Solution Approach 1:
The patent applies preliminary action by pre-positioning anchors in the prostate capsule before delivering the compression mechanism. The anchors are embedded in advance to serve as attachment points for the compression forces, allowing the actual tissue compression to occur quickly and effectively with minimal patient discomfort and faster recovery compared to traditional minimally invasive procedures.
Solution Approach 2:
The patent ensures continuity of useful action by maintaining constant compression force on the prostate tissue through the delivery system. The scope and catheter assembly continuously applies controlled compression forces via the anchors, ensuring sustained treatment effect without the interruptions and discomforts associated with other minimally invasive procedures, thereby improving patient comfort and reducing recovery time.
3Adaptability or versatility
If multiple separate devices are used to deliver anchor assemblies, then treatment flexibility is improved, but device complexity and procedural time increase
Solution Approach 1:
The patent merges multiple anchor delivery functions into a single integrated scope and catheter assembly. This unified device can deliver multiple anchor assemblies sequentially through the same access pathway, eliminating the need for multiple separate devices. The merged system maintains treatment flexibility by allowing deployment of different anchor configurations while reducing device complexity and procedural time through streamlined operation.
Solution Approach 2:
The patent creates a universal delivery system where the scope and catheter assembly can perform multiple functions: delivering different types of anchor assemblies, adjusting compression forces, and adapting to various prostate geometries. This multi-functional device provides treatment flexibility equivalent to having multiple specialized devices but with reduced overall complexity and fewer procedural steps.
4Manufacturing precision
If anchors are implanted precisely at target locations, then treatment effectiveness is improved, but difficulty of reaching difficult-to-access anatomy increases
Solution Approach 1:
The patent uses the scope and catheter assembly as an intermediary tool that extends the operator's reach into difficult-to-access prostate regions. The scope provides visual guidance while the catheter delivers anchors to precise locations that would otherwise be inaccessible. This intermediary system overcomes the difficulty of reaching deep or angled prostate areas by breaking down the delivery path into manageable segments through the urethral catheter access route.
Solution Approach 2:
The patent replaces traditional blind mechanical implantation methods with a scope-guided visual system. The scope allows real-time visualization of the prostate anatomy and anchor placement progress, enabling precise anchor implantation at difficult-to-reach locations. This substitution of blind mechanical delivery with visual guidance significantly improves precision while making previously inaccessible anatomy reachable.
