Tiny Medical Devices – Designing for Success

It’s highly likely that you, as a designer, will run across a part that makes your existing molding supplier sigh, cringe or even groan. It’s times like these that you need to listen to those body sounds and seek out experienced micro manufacturers that work on tiny dust specks every day. Tiny medical devices, micro parts with challenging geometry, wall thickness, L:D or L:T ratios, or multiple materials are welcomed by those experienced and versed in the proven process of success. This “Proven Process” is broken down into a series of proven steps that will fit most tiny medical component and assembly designs. We will break down this Proven Process in five key areas, easily remembered by the letters “V.I.T.A.L”: V: ValidationI: InspectionT: ToolingA: AutomationL: Learning These vital steps will…

Miniaturized Medicine on the Rise

General, Isometric, News

It doesn’t take a brain surgeon (wait, yes it does) to understand the need for tiny devices that can maneuver in delicate tissue, tiny arteries, rigid ligaments, or membrane-like scaffolds. The trend continues and the corresponding need for micro components and assemblies that enable devices across all medical and drug delivery market segments. Some of these devices are as follows: Neurology:• Aneurysm Prevention• Robotic Surgery Devices• Cranial screws• Neuro stimulation• Drug Development Transfection Nozzles Endocrinology:• Glucose Monitoring Needle Assemblies• Insulin Delivery Sheaths Oncology:• Drug-infused membrane patches• Needle Arrays• Transdermal patches Ophthalmology:• Macular Degeneration Laser Nozzles• Aspirators• Capillary Nozzles• Glaucoma Drains• Intraocular Implants• Punctum Plugs• Intraocular Slow Release Drug Delivery Implants Cardiology:• Catheter tips• Biopsy jaws• Robotic Surgery Devices• Ligation Clips Orthopedics:• Bio-resorbable implants• Biomimicry devices• Suture anchors•…

Secrets of Success in Micro Molding – part 2

General, Isometric, News

Micro Molding: High Aspect Ratio, Thin-Wall Micro Molded Devices Secrets of Success in Micro Molding - Part 2 The smallest components in a medical device or drug delivery device are often the enabling components of the device. Examples of these devices are Polymeric needles, catheter sheaths, microfluidic channels, endoscopic links, and PCR wells. As the components of these devices get smaller, the tolerances and wall thicknesses follow suit. Tolerances of +/- 5 microns (~+/- 0.0002”) and wall thicknesses of 25-250 microns (0.001”-0.010”) are common. Although challenges exist in creating these tolerances in both the steel mold and the micro molded components, the determining factor for wall thicknesses this thin is dependent on the aspect ratio, where the wall thickness is with respect to gate location and end of fill. The…

Secrets of Success in Micro Molding – Part 1

General, Isometric, News

Secrets of Success in Molding - Part 1 Medical-device, electronics, and biopharmaceutical manufacturers need new micro-molded products to create tinier, less invasive, and/or space-saving micro devices. Micro-molded components can be as small as dust specks and/or have features that small. State-of-the-art micro parts can have molded features such as dimples around 3 microns in depth and diameter—more than 80 million of them across a surface the size of a microscope slide. The tiniest parts in an assembly are the ones most likely to be a challenge and are also usually the enabling component of the entire device’s form, fit, and function. Similarly, micro tooling created by micro machining is critical to these parts ever making it to validation. Many new advances in micro-machining technology are enabling the design and manufacturing…

Isometric Micro Molding-Specialist in Scalable Intraocular Devices

General, Isometric, News

Micro molding continues to play a significant role in the worldwide growth of ophthalmic devices. The enabling component is usually the smallest component in a medical or pharmaceutical implant or device. This is due to the discomfort of something large being put into the eye. When it comes to our eyes, the smaller the device the better. Age-related eye diseases such as cataracts, diabetic retinopathy, glaucoma, and macular continue to cause loss of vision either significantly or completely. Ophthalmic and intraocular implants are largely made up of many micro-sized and highly precise components and assemblies. CONDITIONS AND TREATMENT: The eye is a complex and sensitive organ. There are many structures and targets, located closely together and sometimes, in terms of a target for treatment, these structures are conflicting with one…

Why 100% Vertical Integration is Important for Micro Components and Assemblies

General, Isometric, News

Complete Vertical Integration : ON SITE and IN SIGHT MATTERS. Working with Isometric Micro Molding maximizes quality and reduces risk. Isometric Micro Molding mitigates customer risk by providing excellence in precision by vertical integration and full control of the tooling, molding, assembly, automation, and CT scanning processes- ALL right here on site and in sight. With extremely accurate tolerances, handling a micro part multiple times can accumulate error, cause product damage, and/or contaminate devices and implants. Many micro molders outsource some portion of a project outside of their company, including the tooling, automation, and metrology. This creates the risk of not only critical timelines and confidentiality, but it also creates the risk of missing critical datum structures established to provide micron-level component or assembly tolerances. Managing each part of the process in-house allows us to maximize…
