Super Hydrophobic and Super Hydrophilic Microfluidic Surfaces

General, Isometric
Super Hydrophobic and Super Hydrophilic Microfluidic Surfaces Polymer micro molding is a scalable and economic method of manufacturing devices with microscopic surfaces, in particular super-hydrophobic and super-hydrophilic microscopic surfaces. These surfaces are created using microscopic and repeated geometric patterns (tiny cylindrical posts and channels).  These features can be fabricated to work collaboratively on the same surface to promote fluid flowing in some areas or prevent fluid flowing in other areas of a device.   Applications requiring these types of microscopic surfaces include: bacteria prevention, cellular adhesion, tissue adhesion, tissue or cartilage growth promotion, frictional drag reduction, wear reduction, and seal and barrier strength applications.  These surfaces also no longer require secondary coating applications which prevent handling and possible surface contamination, simplify sterilization methods, and save device costs.

Micro Medical Device Chips Deliver Pinpoint Pain-Relieving Therapies

Micro Medical Device Chips Deliver Pinpoint Pain-Relieving Therapies

Isometric, News
Micro Medical Device Chips Deliver Pinpoint Pain-Relieving Therapies Often times in micro manufacturing, we use what has been successful in nature.  Commonly, natural pressure, or piezoelectric, capillary, and venture-type actions utilize pressure and surface tension to move fluids to and through implants and needles to move blood or active ingredients to direct places in the body. Isometric Micro Molding, Inc. molds parts the size of salt crystals that are scalable and economically feasible for the treatment of intraocular, cardio, and neurological disorders such as Parkinson’s, Alzheimer’s, Glaucoma, Macular Degeneration, diabetes, oncology skin treatment, and cardiac disease.  The over-molded medical implant chips such described below is one example of the research to empirical test resulting in an enabling technology for many new micro implantable therapy devices using biocompatible micro molded polymer materials.

Eye, Blood, and Joint Fluid Traveling Devices- Where Micro Molding Meets 3D Printing

Eye, Blood, and Joint Fluid Traveling Devices- Where Micro Molding Meets 3D Printing

Isometric, News
Eye, Blood, and Joint Fluid Traveling Devices- Where Micro Molding Meets 3D Printing It’s long been known that micro vs. macro physics have thwarted some efforts to create micro components and assemblies.  The study of Newtonian (fixed viscosity) and Non-Newtonian fluids (variable viscosity) fluids have an unique impact on developing and scaling drug delivery devices and body-fluid flow.  Non-Newtonian fluids can be found in the blood, the eye, and in joint fluid and micro implants, swallowable devices, and tiny motion devices can be helped along with a change in viscosity. This research also brings 3d printing and micro molding technologies together, which will happen more and more as the 3d printing and materials very quickly are developed.  Isometric is excited to be positioned well in this market space.  Kudos to Max…

The Four Legs That Drive MICRO Success

The Four Legs That Drive MICRO Success

Articles, Isometric
The Four Legs That Drive MICRO Success The “four legs” that support Isometric Micro Molding are micro molds, micro injection molding, micro automation, and CT scanning. When a moldmaker serving injection molders of medical parts decided to get into micromolding itself, the first priority was to obtain the right equipment. For Isometric Micro Molding, Inc., New Richmond, WI, that meant buying the right injection machine, using its existing microautomation expertise for post-mold handling and assembly, and obtaining something still quite rare among custom molders—a CT scanner for process validation and in-process inspection. The firm started out in 1990 as Isometric Tool & Design Inc., building molds for producers of medical and drug-delivery components. Its medical OEM customers needed assistance with micro-sized parts, so the firm purchased a building across the street…

What is a Brain Perfusion Phantom?

What is a Brain Perfusion Phantom?

General, Isometric, News
A brain perfusion phantom is a 3D printed plastic brain that allows surgeons to practice mechanical thrombectomies. A mechanical thrombectomy is a procedure where surgeons thread a wire from the chest, through the neck, and into the head to pull clots out of the brain of a stroke victim. As you can imagine, there are a lot of risks associated with this procedure, like the wire loosening another clot from the wall of the artery and it lodges in the heart, lung, or brain. Computer simulations of this procedure exist but are extremely expensive to purchase for med students to use. And as you can imagine, neurosurgeons need extensive training on this procedure before working on a human being. That is why a UConn Health radiologist and a medical physicist…

Tiny Medical Devices – Designing for Success (part 2)

Tiny Medical Devices – Designing for Success (part 2)

General, Isometric, News
Tiny Medical Devices – Designing for Success (part 2) VALIDATION Picture this – your medical device is designed and you’re ready to validate the tiniest component – the technology piece that enables your intellectual property. You dive in headfirst, knowing your part has +/- 5 micron tolerances on a plastic part. You start like any engineer would start – with a solid stack-up tolerance plan and <20% gage R&R – you should be fine, right? Consider this general micro molding rule of thumb – BEFORE you even design the injection mold. If you work backward with the numbers, you’ll have ~0.0004” total tolerance Total   10 microns = (0.000397”) Tooling = 20% of 10 microns = 0.00008” (wow, really? This is difficult to do but SO critical to hitting the final…

The Merging of Medical Device Manufacturers and the Pharmaceutical Industry

The Merging of Medical Device Manufacturers and the Pharmaceutical Industry

General, Isometric, News
The Merging of Medical Device Manufacturers and the Pharmaceutical Industry As product technology advances and the general demand for healthcare expands, the industry line between medical device manufacturers and pharmaceutical companies is being blurred as innovative products continue to emerge. Manufacturers are exploring new technologies that adhere to better patient compliance, improve product safety and utilize unique drug delivery methods. These new technologies include:- Small adhesive patches that are encapsulated and swallowed. Once in the body they dissolve and stick to the wall of the intestine to deliver time-released medication- Implantable devices that automatically run tests and dose medications- Transdermal patches that are embedded with micro-sized needles that deliver medication over a period of time As technology advances and healthcare treatments become more complex, the pharmaceutical and medical device industries…

Micro Scale Manufacturing

Micro Scale Manufacturing

Isometric, News
The Big Trend For Small Devices is Drug Delivery One day in the late 1980s, Donna Bibber looked over the shoulder of a “mad scientist” colleague at Corning Life Sciences – he was working on lab-on-a-chip technology, and Bibber realized that it could be a game-changer. She is now Vice President of Isometric Micro Molding, which addresses the growing market need for expertise in device miniaturization. Isometric specializes in making and assembling tiny components, primarily for medical device companies. Some of the work is quite experimental – only around one approach in ten gets taken to the next level – and, as Bibber puts it, they have to “kiss a lot of frogs.” Bibber divulges the current trends and challenges in the world of the production of micro-scale drug delivery…
