Combination ED Therapy: Counter-Pulsation, Shockwave, Carboxy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for erectile dysfunction, such as medications and physical therapies, have limited effectiveness and can come with side effects or interact with other drugs, necessitating a more effective non-medical approach.
Innovation Solution
A method combining external counter-pulsation treatment to increase blood flow, low intensity shockwave therapy to stimulate blood vessel growth in the penile area, and carboxy therapy by injecting carbon dioxide into the corpora cavernosa to enhance pliability and blood flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If PDE5 inhibitors are used to treat ED, then blood flow to corpora cavernosa is increased, but side effects and drug interactions occur
Solution Approach 1:
The patent replaces the pharmacological mechanism of PDE5 inhibitors with a mechanical/physical treatment approach. External counter-pulsation therapy uses mechanical compression and decompression of the penile tissue through inflatable cuffs, stimulating blood flow through mechanical means rather than chemical inhibition of PDE5 enzymes, thereby avoiding drug-related side effects and interactions.
Solution Approach 2:
The patent extracts the treatment approach from the pharmacological system and places it in a physical therapy system. By removing dependence on PDE5 inhibitor medications and using instead external counter-pulsation devices and low-intensity shock waves, the treatment eliminates harmful drug interactions while maintaining the goal of increasing blood flow to corpora cavernosa.
2Reliability
If external counter-pulsation therapy is applied to increase blood flow, then cardiac output increases, but effectiveness is limited to a limited number of patients
Solution Approach 1:
The patent combines multiple treatment modalities into a comprehensive protocol: external counter-pulsation therapy is integrated with low-intensity shock wave therapy and intracavernosal injection therapy. This combination approach addresses different pathophysiological mechanisms simultaneously, increasing the overall effectiveness and adaptability across diverse patient populations compared to single-modality treatments.
Solution Approach 2:
The patent employs parameter changes in the shock wave treatment protocol, using low-intensity shock waves with specific energy levels (0.09-0.18 mJ/mm²) and pulse rates (300-600 pulses per minute). These optimized parameters enhance the treatment's effectiveness in stimulating neovascularization while minimizing adverse effects, thereby improving patient responsiveness.
3Reliability
If low intensity shock waves are applied to stimulate blood vessel growth, then neovascularization is promoted, but effectiveness by itself is limited
Solution Approach 1:
The patent merges low-intensity shock wave therapy with external counter-pulsation therapy and intracavernosal injection therapy in a sequential treatment protocol. The shock wave component is combined with mechanical compression therapy and pharmacological injection, creating a synergistic effect that enhances neovascularization and improves overall treatment productivity compared to shock wave therapy alone.
4Reliability
If a combination of treatments is used, then blood flow and neovascularization are significantly increased, but treatment complexity increases
Solution Approach 1:
The patent segments the treatment protocol into distinct phases: an initial phase of external counter-pulsation therapy, followed by low-intensity shock wave therapy, and concluding with intracavernosal injection therapy. This segmentation allows each modality to be applied optimally at the appropriate time, managing overall complexity through structured sequencing while achieving superior blood flow enhancement.
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
This combination treatment significantly increases blood flow and stimulates neovascularization, improving erectile function by doubling blood flow through major vessels and promoting vascular growth, offering a more effective alternative to existing methods with reduced side effects.
Implementation Method 1
applying a plurality of counter-pulsations to the cuff; during a diastole sensed by the ECG, inflating the cuff to a predetermined pressure; and (v) during onset of a systole sensed by the ECG, rapidly releasing pressure from the cuff
Implementation Method 2
applying shock waves having a maximum energy of 0.09 mjmm2 to the penile area at a predetermined rate for a predetermined amount of time per treatment
Implementation Method 3
injecting about 160 cc of carbon dioxide into the corpora cavernosa at four different sites along the shaft of patient's penis twice per week

AI summary
In a method of treating erectile dysfunction in a patient, a predetermined course of external counter-pulsation treatment is applied to a lower body portion of the patient. After the predetermined course of external counter-pulsation treatment is applied, a predetermined course of low intensity shockwave treatment is applied to a penile area of the patient. After the course of low intensity shockwave treatment, a predetermined course of carboxy therapy is applied to a corpora cavernosa of the patient.
