At LIM Innovations we empower people with limb loss to live beyond the limits of their prosthesis and achieve the mobility and independence they deserve. We provide functional, forward thinking products, and data-driven solutions in the O&P industry. Our core company values focus on developing technology that addresses the unmet needs of patients and clinicians. We integrate advanced technical solutions and materials with unique design advantages to maximize comfort and performance.
The Infinite Socket ® system is the first custom molded, modular, and dynamic trans-tibial (TT) socket, offering adjustability at each component. The combination of advanced materials and adjustable systems empowers patients and clinicians to adjust the prosthesis in response to volume and shape change of the residual limb.
Modern materials and advanced designs drive our hallmark goal of bringing greater comfort and function to the lives of amputees. A combination of solid components and soft goods create a structured system with optimal comfort. The metal base plate, carbon fiber struts, and re-moldable interfaces make up the solid structure. Molded textiles are engineered to allow movement of the leg and optimize weight distribution. They are made of easy-to-clean and low friction materials to maximize comfort and control. By replacing the rigid structure of a traditional socket with moldable materials, the Infinite Socket allows patients to control the fit of their socket as their limb changes.
Adjustability & Modularity
The Infinite Socket system is equipped with closure systems for on-the-fly adjustment of the socket. The closure mechanisms are optimally placed and ergonomically designed to give the amputee control in any situation. The primary macro-tensioning system facilitates easy donning and doffing of the socket, establishing a base level of fit, while small adjustments can be made to optimize the fit.
A rigid solution to a dynamic problem
The human foot is made for comfortably and effectively transferring our weight and forces for walking. Following amputation a prosthetic socket must mirror this behaviour way that avoids pain and skin breakdown. Prosthetic sockets are traditionally rigid carbon fiber and plastic shells that do not mimic the human body. LIM Innovations is reorienting the conceptual framework to improve function for millions of amputees. The science of engineering is in constant interplay with the art of human experience to prevent limitations. For LIM Innovations, function is analyzed and categorized as its own entity, driving design and engineering. User needs and feedback are the catalyst behind product development and laying the framework for functional outcomes. Beyond providing a functional prosthetic socket, the LIM Innovations RnD team is focused on improving the continuum of care, patient outcomes, and rate of acceptance among users. Less than 50% of amputees wear their prosthesis regularly, and the primary cause of prosthetic abandonment is socket discomfort. LIM Innovations is committed to serving the nearly 2 million amputees currently living in the United States, and 185,000 people facing amputation each year.
The Infinite Socket represents a solid framework to understand the LIM Innovations approach to design. Traditional sockets can be likened to a wooden clog - a fixed, rigid shape, that does not change with the user's residual limb. The Infinite Socket was set out to perform like the most advanced athletic trainer - a combination of advanced materials and adjustable systems, empowering clinicians and users to adjust the prosthesis in response to volume and shape change at the residual limb. The Infinite Socket intends to capture the dynamic nature of human anatomy, skeletal and musculature.
LIM Innovations is proud to have a solution for one of the most challenging problem in the prosthetic industry. Our design and digital fabrication methods introduce a modern approach to socket technology, focused on end-user satisfaction and improved quality of life. we have successfully reduced the 17-step traditional fabrication process, brought modularity and adjustability to the prosthetic socket, and improved patient outcomes in a scalable fashion.
LIM Innovations has addressed these issues by introducing The Infinite Socket TT, a custom-molded, dynamic socket system. The combination of a modular frame and advanced pressure distribution systems enables clinicians and patients alike to adjust the socket on-demand. The biomechanics and concept of the Infinite TT are designed in response to activity demands, pressure areas, and shape change of the amputee's residuum.
Every aspect of the Infinite TT was designed, engineered , and tested with the user's needs front and center.Other socket designs and traditional sockets can not adapt with the body as the body changes and they do not mimic anatomy.
Here are some of the exciting features of our product:
The Infinite TT integrates advanced textiles and pressure distribution systems with a dynamic frame. The thermoplastic carbon fiber frame, hinging posterior strut, and BOA closure system draw in the medial and lateral walls to improve bio-mechanical control. The advanced pressure distribution system incorporates height adjustment and air bladders, designed in response to activity demands, pressure areas, and shape change. With a view to improve functional outcomes, the Infinite TT was developed from the ground up with the amputee in mind.
Soft Shell Cover
The soft-shell outer cover protects the sockets integral components and the patient's clothes from general wear and tear.
The frame is made up of three modular and thermoplastic carbonfiber struts that connect to an adjustable base plate. This frame offers multiple points of adjustability and is designed to provide dynamic response flex. This anatomical design mimics anatomy and is engineered for shock absorption and energy return.
The entire frame assembly can be slid anteriorly or posteriorly with side access set screws for fast relief to bony prominence and pressure distribution control.
Suction: combines with a seal-in liner to engage the FIL cup for proper suction suspension.
Pin Lock: features an anti-rotational feature built into the funnel ensuring reliable suspension and bio-mechanical control for the patient.
The hinging posterior lift assembly, patellar tendon bracing system, and inner textiles combined with a BOA closure system provide a dynamic closure system. Now the patient can easily loosen the fit of the entire socket while sitting, flexing their knee, or relaxing.
Dynamic Closure System
The BOA closure system is designed to provide an optimal fit for the patient that can be adjusted for various activities, daily volume change, and easy donning and doffing of the socket.
LIM Air Bladder System
This system is designed to evenly distribute pressure regardless of volume change. They are anatomically placed for patient ease of use. They are made with high strength fabrics for improved durability and are backed with a custom-molded, plastic layer.
Low Friction Textile Layers
The abrasion resistant and low friction textile layer combines with a remoldable thermoplastic material to provide structure and custom contours. The integrated height adjustable system is cushioned and equipped with air bladders to improve pressure distribution and protect sensitive areas.
Functional Outcome Measures
Clinical evidence shows that socket fit is a key factor in determining successful patient outcomes. We utilize data metrics to measure the improvements experienced by patients wearing the Infinite Socket system and to innovate prosthetic designs based on the results.
Functional Outcome Measures:
• 54% improvement on Socket Comfort Score
• 14% mobility increase in 4 Square Step Test mobility Test
• 11% efficiency improvement on 2 Minute Timed Walk Test
