In the fall of 2005, Bob Elson, vice president of engineering at Coapt Systems Inc, wanted to develop their design for a new cosmetic surgical device, known as the Surgiwire Incisionless Dissector, into a finished product ready for shipment to surgeons.
Requiring 100% inspection and identification is essential for most products. Low-volume production often goes hand-in-hand with high costs, particularly if the variety of products concerned is also extensive.
Digital, 3D systems are enabling orthotic and prosthetic devices that provide a better fit and a shorter manufacturing time over more traditional solutions.
Selecting the wrong pump for a medical instrument can lead to costly manufacturing delays, dangerous device failures, or even reputation-damaging product recalls. Therefore, it is critical that designers have the minimum parameters they need to consider in mind when making their choice.
Many systems require a variety of different capabilities, such as air, fluid, and electronics, to be connected to a tool. As such, device manufacturers must ensure that each element is kept completely separate from each other. This can be especially challenging at the connection point.
The Project: Connect the various subsystems of a left ventricular assist system with a solution that offers reliability and durability. The Solution: Utilize cable assemblies that enable easy, but not accidental, disconnects, and provide a comfortable feel for patients.
The Project: Eliminate the issues that exist with the uncoated acrylic over the LCD flat-panel display on a cosmetic system. The Solution: Use an abrasion-resistant optical-grade acrylic sheet that functions like glass, but is significantly lighter and more durable.
Phoenix Medical Products, a contract manufacturer of various devices used in a number of medical markets, has one department devoted entirely to needle design, production, sterilization, and packaging, as this work has a unique set of challenges.
Dispense valves can be a vital tool in the assembly and manufacture of medical devices. However, choosing the correct type to use for a particular application may not always be abundantly clear.
The ideal treatment for replacing a part of the body with an implant would be to restore the area to a natural state. Unfortunately, this is not possible with traditional materials used for spinal implants, which can cause issues for the patient in years following surgery.
Medical device manufacturing companies don’t have the luxury of being able to choose between either focusing on speed to market or FDA compliance. Rather, they must address both equally.
The Project: Effectively read a 2D Data Matrix barcode off surgical instruments that differ in terms of reflectivity and shape. The Solution: Use an ID reader that employs an innovative combination of lighting, software, and optics to achieve success.
Outsourcing using concurrent engineering practices provides the hands-on approach for a company that enables it to gain the most in efficiencies from manufacturing. It can be used by virtually any company of any size and applied to any medical device, product, or component.
By Kevin Duggan Medical device companies have achieved significant improvement using lean techniques. Improvements in quality, productivity, lead time, inventory, on-time delivery, and cost have been obtained and further improvement continues each day.
By Jeff Randall, PE As medical technology advances and the demands on surgical parts increase, the need for high-quality, tight-tolerance components continues to rise.
The Project: Resolve the start/stop action of a hybrid piston syringe pump to achieve a steady and regular flow stream. The Solution: Use a servo controller and calibration table to dynamically vary the pump velocity as a function of requested flow rate and pump dynamics.
Everyone everywhere seems to be "going green" but is there real value in doing so or is it just a
This article compares the specific characteristics of solenoids and motors, their common properties, and those attributes that make each of these electromechanical devices unique for a specific medical motion application.
Patient safety is of paramount importance during a surgical procedure, while avoiding preventable errors during the procedure can result in significant cost savings.
Product Development Technologies, Inc. (PDT), a division of TZ Limited was enlisted by Heathrow Scientific to develop their next generation pipette filler, the Rota-Filler 5000 (RF5000) Pipette.
The idea has been thought up, the "napkin sketch" has been made, and the project is ready to move forward. So what's the first "real" step in the design process? This was the question for the participants in this month's Perspectives feature.
Electronic components used in medical devices can often experience much shorter lifecycles than the products in which they are used. With the additional challenges that come from replacing a part in a finished device, it is best to be as prepared for this inevitable process as possible.
Microwelding provides the medical device industry with yet another manufacturing solution option that enables OEMs to achieve further miniaturization of their products. It can be an ideal alternative to additive joining processes for a number of reasons.
The assembly industry is vast in its scope and incorporates many independent disciplines for device manufacture. A primary segment of the assembly process that is naturally designated for automation is dispensing.
Adhesive technology is critical to many aspects of medical device technology, from securing components within a finished device to adhering wound care products or electrical pads directly to a patient's skin.
