Post-Implant Compression Balloon for Controlled Hematoma Pressure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for preventing hematomas, swelling, and scarring after cardiac device implantation are inadequate, relying on unreliable pressure application and are difficult to implement due to the lack of bony continuity in the chest region, leading to increased risks of infection and suboptimal cosmetic healing.
Innovation Solution
A compression apparatus with a surgical balloon and suspension system that applies consistent pressure through a combination of balloon inflation and lateral straps, featuring visual feedback cues and optional pressure sensors to ensure proper application, independent of the underlying surface characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stress or pressure
If conventional pressure dressing is applied, then the procedure is simple to implement, but the pressure delivered is inadequate (3-7 mm Hg) to combat venous or arterial pressure
Solution Approach 1:
The patent employs a balloon-based compression device that uses pneumatic inflation to generate and maintain controlled pressure at the surgical site. The balloon can be inflated to deliver therapeutic pressure (exceeding venous and arterial pressure) while the suspension system provides structural support, resolving the contradiction between achieving adequate pressure and maintaining procedural simplicity.
Solution Approach 2:
The device allows dynamic adjustment of compression pressure parameters through controlled balloon inflation. The pressure can be titrated to achieve therapeutic levels (above 20 mm Hg to overcome venous pressure and 60 mm Hg arterial pressure) while maintaining patient comfort and tissue perfusion, thus improving pressure delivery without excessive complexity.
2Reliability
If gauze stretch bandage is used, then the application is crude and simple, but the pressure application is unreliable and the dressing dislodges over time
Solution Approach 1:
The compression device is segmented into distinct functional components: a balloon element for pressure delivery, a suspension system for stabilization, and a securing mechanism for fixation. This segmentation allows each component to perform its specific function reliably while maintaining ease of application through modular assembly.
Solution Approach 2:
The balloon component utilizes flexible membrane technology to conform to the anatomical contours of the chest wall, providing reliable and uniform pressure distribution. The flexible nature of the balloon allows it to adapt to the irregular surface of the chest region, ensuring consistent contact and pressure application without dislodgement.
3Stress or pressure
If sandbag or icepack is used, then the method is simple, but the pressure is difficult to control and maintain consistently
Solution Approach 1:
The balloon-based device provides dynamic pressure control through adjustable inflation, allowing the pressure to be optimized and maintained at therapeutic levels. The suspension system dynamically adapts to patient movement and positioning, maintaining consistent pressure application throughout the postoperative period, unlike static sandbags or icepacks.
Solution Approach 2:
The device incorporates visual readout mechanisms that provide feedback on the pressure being exerted on the anatomical site. This feedback system allows for real-time monitoring and adjustment of compression pressure, ensuring it remains within the therapeutic range needed to prevent hematomas and swelling while avoiding excessive pressure that could compromise tissue perfusion.
4Object-affected harmful factors
If shoulder sling is worn, then lead dislodgement is prevented, but it does not provide adequate pressure for hematoma prevention
Solution Approach 1:
The compression apparatus integrates multiple functions into a single device: it provides hematoma prevention through controlled compression, maintains lead positioning through the suspension system, and offers patient comfort through adjustable pressure. This multi-functional design eliminates the need for separate shoulder slings and compression dressings, providing both hematoma prevention and lead protection simultaneously.
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 apparatus effectively reduces hematomas, keloids, and improves cosmetic healing by ensuring uniform pressure application, reducing the risk of infection and enhancing scar appearance.
Implementation Method 1
The efficacy of the procedure depends on the skill of the provider, unreliable application of pressure over the desired site... The venous pressure in most patients is over 20 mm Hg and mean arterial pressure is at least 60 mm Hg. Therefore, the current range of pressure delivered using such conventional approaches is inadequate to combat venous or arterial pressure.
Implementation Method 2
A compression apparatus with a surgical balloon and suspension system that applies consistent pressure through a combination of balloon inflation and lateral straps
Implementation Method 3
Other aspects of the present disclosure include an apparatus, system, and method that optionally provide visual read outs of pressure exerted on the anatomical site with a feedback sensor, if used.

AI summary
A pressure system and method for managing post-operative swelling. The pressure system has a balloon with a quadrilateral basal skirt that surrounds a surgical site on a patient. A plurality of strap-receiving slots is located in the skirt. Adhesive pads are affixed to the patient outside the skirt. One or more tensioning straps are deployed between the strap-receiving slots and the adhesive pads so that tension can be applied to the straps and to the skirt in order to press the balloon upon the surgical site. Optionally, means for generating visual feedback cues are provided to enable the operator to determine appropriate compression and assess skin recoil feedback. Such means may signify swelling reduction and skin turgor.
