It’s about figuring out how and where to go with the cardiac ablation and then engineering the best catheter-based delivery device, according to a top Acutus Medical scientist. Cardiac ablation is when a physician intentionally destroys a small amount of tissue in the heart to treat and prevent heart rhythm problems. The procedure creates … [Read more...] about Design challenges to overcome when developing cardiac ablation devices
Coextrusion is the process of pressing two or more materials into a single piece of tubing. Coextruded tubing is commonly used in the packaging and medical device industries. For example, multi-layered extruded tubing can be used for drug delivery applications, including insulin delivery, angiography and pain therapy. Coextruded tubing can … [Read more...] about What is coextrusion?
Paratubing is a form of tubing that is made from two or more round tubes that are conjoined during extrusion. Paratubing, also called parallel tubing, comes in a wide range of thermoplastics and designs with electrical properties and signal carrying capabilities. The tubes are produced as multiple single lumen PVC tubes that are longitudinally … [Read more...] about What is paratubing?
Health providers use echogenic catheters to improve visibility in a number of ultrasound-guided catheterizations. The catheters have been used in many applications. For example, echogenic catheter-over-needle systems can be used for continuous nerve block. Echogenic catheters have also been used for ultrasound-guided embryo transfer in in vitro … [Read more...] about What is an echogenic catheter?
A microcatheter is a small diameter catheter that is used in minimally invasive procedures for delivering devices. Its small build makes it ideal for navigating complex vasculature within the human body. Microcatheters are small 0.70-1.30mm diameter catheters that are used for guidewire support, exchanges, to access distal anatomy, cross … [Read more...] about What is a microcatheter?
Medical tubing allows clinicians to administer fluid and or even devices — as well as potentially allow for gas flow. And that's just the beginning. Common applications of medical tubing include ventilators and IVs, but tubing also finds uses supporting access devices and as a delivery method for other devices. For example, tubing can be used to … [Read more...] about What is medical tubing used for?
Cardiac catheterization is a procedure in which a catheter is inserted into an artery or vein in the groin, neck or arm and threaded to the heart. Diagnostic tests can be performed using the catheter during catheterization, according to the Mayo Clinic. Coronary angioplasty and coronary stenting are also performed using cardiac … [Read more...] about What is cardiac catheterization?
As the medical industry migrates more to multi-layer, multi-lumen tubing for various uses, the extrusion die design and manufacturing supply chain has likewise evolved. That includes new crosshead designs. Bill Conley, Guill Tool & Engineering Medical tubing manufacturers are increasingly turning to assorted types of multi-chambered … [Read more...] about Crosshead construction for medical tubing: What you need to know
Most small hand-held devices used for surgery include some type of tubing technology. The design engineer ultimately must decide whether drawn tubing or a rolled tube technology will best suit a particular device. Jim Jock, Micro Metal tubes are frequently used for the shafts of disposable and reusable medical instruments. The tubes can be … [Read more...] about What is metal tubing for medical devices?
