Prostate Tissue Compression and Repositioning for BPH Relief
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for Benign Prostatic Hyperplasia (BPH) often come with significant adverse effects, such as side effects from medications and complications from surgical procedures, and do not provide immediate relief, requiring hospital stays and prolonged recovery times.
Innovation Solution
The development of devices and systems that use anchoring and tensioning elements to compress or reposition prostatic tissue, reducing urethral constriction without substantial displacement of the urethra, and methods for cutting tissue to relieve pressure on adjacent anatomical structures, allowing for less invasive procedures with reduced risk of complications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional surgical procedures are used to treat BPH, then urethral constriction is relieved, but complications and adverse effects increase
Solution Approach 1:
The patent replaces traditional mechanical surgical procedures with a minimally invasive system that uses a probe to deliver energy (such as radiofrequency or microwave) to the prostate tissue. This energy delivery mechanism causes thermal ablation or coagulation of the hyperplastic tissue, eliminating the need for mechanical cutting or resection instruments and thereby reducing surgical complications.
Solution Approach 2:
The patent introduces an intermediary energy delivery mechanism (electromagnetic or thermal energy via the probe) between the external device and the target prostate tissue. This intermediary energy form allows for precise, controlled tissue treatment without direct mechanical contact, reducing the risk of bleeding, infection, and other surgical complications.
2Reliability
If medications are used to treat BPH, then symptoms are managed, but side effects occur
Solution Approach 1:
The patent substitutes pharmacological treatment with a physical/energy-based treatment mechanism. Instead of using medications that have systemic side effects, the system delivers focused energy directly to the prostate tissue to reduce hyperplasia, thereby managing symptoms without the harmful side effects associated with medication.
Solution Approach 2:
The patent extracts the problematic element (medication with side effects) and replaces it with a localized physical treatment. The treatment directly addresses the root cause (prostatic hyperplasia) through energy delivery, eliminating the need for systemic medications and their associated side effects.
3Reliability
If invasive procedures are used to treat BPH, then urethral obstruction is relieved, but recovery time increases
Solution Approach 1:
The patent replaces invasive mechanical procedures with a minimally invasive energy delivery system. The probe-based approach allows for treatment through small incisions or existing urethral openings, avoiding the need for large surgical incisions and prolonged healing periods, thus significantly reducing recovery time.
Solution Approach 2:
The patent segments the treatment process into a minimally invasive delivery phase (through small openings) and a rapid healing phase. By using a probe that can be inserted through small urethral openings rather than requiring large surgical incisions, the procedure is divided into a quick insertion/treatment phase and a brief recovery phase, reducing overall treatment time.

AI summary
Devices, systems and methods for compressing, cutting, incising, reconfiguring, remodeling, attaching, repositioning, supporting, dislocating or altering the composition of tissues or anatomical structures to alter their positional or force relationship to other tissues or anatomical structures. In some applications, the invention may be used to improve patency or fluid flow through a body lumen or cavity (e.g., to limit constriction of the urethra by an enlarged prostate gland).
