Top Medical Device Trends in 2021

Medical devices are constantly evolving in order to identify and treat medical conditions more efficiently and effectively. The trend toward digital, remote technologies was well underway before Covid-19, but the pandemic significantly increased the demand for remote patient monitoring and care. For these reasons, there have been significant advancements in telemedicine and telehealth – and analysts agree this trend is expected to continue. Opportunities abound for growth and innovation within the medical device industry, and below are the top 5 medical device trends in 2021 and beyond.

1. Further Expansion of IoMT

The Internet of Things (IoT) is simply the use of the internet in everyday objects. The IoT is playing a big role in medical devices. Connected, or “smart” medical devices provide a wide range of data such as blood pressure, body temperature, and blood sugar for healthcare providers. This data can be used for various applications ranging from prevention, diagnosis, monitoring, and therapy. In 2021, we will continue to see the IoT evolve into the Internet of Medical Things (IoMT), which will utilize IoT devices, telemedicine, and telehealth technologies – all of which facilitate remote patient care. IoMT apps and devices optimize patient care and improve operational efficiency of medical services. Examples of the IoMT applications include an electrocardiogram monitor that will detect irregular heartbeats or rates that are too low as well as diabetes devices such as smart insulin pens and glucose meters.

2. Continued Demand for Wearables

Examples of wearable devices are a Fitbit to count your steps or a similar device to track your heart rate. There are millions of people worldwide with wearable, connected devices and this figure is growing as the demand increases for wearables, such as smart watches, exercise trackers, oximeters, and heart rate monitors. These devices collect valuable data that enables the patient and healthcare provider to manage health remotely, flagging any potential issues. Wearables are also in high demand for individuals that do not have a given medical condition and simply wish to improve overall wellness. As demand for more personalized wearables increases, tech companies are busy developing new innovations.

Additionally, wearable devices present a huge opportunity to collect data for clinical trials. This type of data is simpler and faster to collect as well as less expensive, allowing researchers to make real-time assessments on the patient’s well-being – rather than wait for data collection via surveys and focus groups. There are already many clinical trials taking advantage of wearable devices and we expect this number to grow significantly in 2021 and beyond.

3. Sensors, Sensors, and More Sensors

One of the biggest booms in medical device technology is sensors. These come in various shapes and sizes and include chemical, optical and pressure sensors that are used in wearable and even ingestible devices. Medical device sensors have the ability to link data collection to real-time decision making, which will allow the healthcare industry to shift more towards individualized patient care. For example, we are seeing the development of an ingestible device with sensors that remain in the stomach for over a month, collecting measurements and administering medicine based on the data-collected.

Biosensors are one of the latest innovations. One example is a bandage or patch with a sensor enclosed to monitor sweat and/or blood to track a patient’s condition and alert the individual or healthcare provider if an intervention is necessary. More medical device technologies like these are expected to be underway in 2021.

4. Increased Utilization of Robots

Artificial intelligence (AI) is becoming more of a presence in healthcare facilities, and one of the fastest growing forms of AI are robots. In many hospitals, robots are already performing repetitive tasks such as restocking supplies or assisting with disinfecting activities. Robots are also assisting doctors with surgeries in the operating room.

Robotics innovations are resulting in robots capable of more complex and intricate tasks. A huge area for research and development is nanomedicine. One advancement underway is the creation of tiny microbots that are capable of entering a patient’s capillaries to assess and repair human tissue. This is an exciting development and, in the future, may result in a treatment for cancer or other diseases that includes a patient swallowing a pill that encapsulates a programmable microbot.

5. Expanded VR Device Usage

Virtual reality (VR) is a computer-generated simulation that can be interacted with in a seemingly real way by an individual wearing special equipment such as goggles or a helmet. In the healthcare community, VR devices are used for medical staff training as well as patient care.

Doctors, nurses, and medical students use VR to practice their skills and simulate “real” medical procedures in what they perceive as a healthcare environment. This hands-on training is invaluable and is believed to translate to higher knowledge retention.

When it comes to patient treatments, VR is used as therapy to treat a variety of conditions such as depression, anxiety, vision problems, and post-traumatic stress disorder (PTSD). For PTSD care, patients are able to explore a simulated environment to determine what triggers a response and how to work through a patient’s emotions and responses to said triggers – all from a safe environment in the presence of a healthcare professional.

VR medical devices are expected continue to play a big role in product development in 2021 and beyond.

Compression Molding 101

From surgical instrument handles and catheters, to drug-eluting implants and stents, different jobs require different devices to be made – and different devices in turn, require different fabrication techniques. The following article on Compression Molding 101 provides an overview of the compression molding process as well as the advantages and disadvantages of this technique.

Compression molding is one of the most common closed-molding techniques and was initially developed to produce products for metal replacement applications, namely within the automotive sector for parts such as hoods and fenders. Use of this molding method has expanded significantly and it is now used to manufacture products for a wide-range of industries, including the healthcare sector.

The compression molding process starts with a thermoset elastomer, such as Liquid Silicone Rubber (LSR), that is often preheated and loaded into an open, heated mold cavity. Next, the mold halves are closed. Unlike injection molding and transfer molding where the molded material is forced into the cavity, compression molding forces the heated cavity onto the material and the silicone is forced into the shape of the mold. Heat and pressure are maintained within the cavity and the mold is held in place until the silicone has cured. It is important to note that the mold is heated, and the silicone is often preheated, to ensure the material is permanently cured during molding via a step called vulcanization. The molded part is cooled and removed from the mold, sometimes with the aid of an ejector pin, and the process is ready to begin again. Cycle times depend on the size and thickness of the molded parts, and how long the material needs to adequately cure. Click here for a simple graphic of compression molding equipment.

Compression molding yields high strength parts in a wide variety of sizes, and is ideal for efficient fabrication of consistent, quality parts. This process can be used for small, medium and high volume runs. Compression molding is known for excellent part-to-part repeatability.

There are several advantages to manufacturing products via compression molding. First, this method often involves tools that are less complex and less costly to construct, resulting in lower manufacturing costs compared to other molding techniques. Compression molding tooling can be fabricated of aluminum or other lower cost materials, further reducing tooling expenses. Second, compression molding is capable of fabricating large and even heavy products that other molding process may struggle to manufacture. Third, this technique generates less waste compared to other methods as there is no runner system or gates to trim off, which can be a huge cost savings when working with expensive compounds. Finally, there is little set-up time required for compression molding.

While there are many advantages of compression molding, there are also some key disadvantages. Compression molding cannot easily fabricate complex and intricate product designs. The flow of elastomer within the cavity is limited, making it difficult for material to get into the hard-to-reach spaces of complex parts. Additionally, this technique is not able to accommodate all product features. For example, compression molding is typically not able to utilize undercuts in the part design as this feature would make ejecting the cured product very difficult. Another disadvantage of compression molding is cycle time – in general, compression molding processes have higher cycle times than other techniques such as injection molding or transfer molding.

Compression molding is an excellent method but it is not the right choice for every project. This is why it is important to work with a trusted molding partner, like ProMed, who will guide you through the molding selection process to determine if compression molding, or another molding technique, is the best option for your specific project!
