Revamp Medical’s New Doraya™ Intravenous Catheter Offers Hope to Heart Failure Patients
Revamp Medical’s New Doraya™ Intravenous Catheter Offers Hope to Heart Failure Patients
Revamp Medical’s Doraya™ intravenous catheter for treating acute heart failure
The FDA has granted Breakthrough Device Designation for Revamp Medical’s new Doraya™ device, a temporary intravenous catheter for the treatment of acute heart failure. The designation allows the FDA to expedite the review and approval of designated devices when they may help save lives from devastating diseases, such as acute heart failure (AHF). According to Revamp Medical, over 1 million people are hospitalized every year in the US alone with AHF, 20-30% of those have a poor response to diuretic therapy, and 25% will be readmitted within 30 days.
The Doraya™ percutaneous device can be temporarily placed below the renal veins in the inferior vena cava to improve a patient’s diuretic response by temporarily reducing the central venous pressure with a partial adjustable flow for up to 12 hours. The device is currently in human clinical studies in Europe and will hopefully be available faster to help patients thanks to the Breakthrough Device Designation. With more than 26 million people suffering from heart failure around the world, intravenous catheters and other medical tubing devices like the Doraya™ can help prevent deaths and reduce hospital stays and readmissions.

Requirements Extrusion Processors Need to Know Before Jumping In the Face Mask Market
Requirements Extrusion Processors Need to Know Before Jumping In the Face Mask Market
Face mask filter material requires specialized extrusion processing
Many extrusion companies may be wondering what equipment modifications are needed to enter the booming face mask market. One of the common filtering materials is made using a melt-blown extrusion process using PP or other high-flow polymers that are then sandwiched between two layers of waterproof fabric. Melt-blown fiber extrusion uses die tooling with tiny holes spaced 0.010 to 0.015 in. apart, with up to 1000 holes per foot of the die width. A high extruder discharge pressure forces the polymer through the holes in the die before they are then stretched, randomized, cooled, and deposited on a vacuum collector drum.
Not all extruders are able to meet the demands of these high-flow, low-viscosity polymers. Smooth-bore extruders cannot keep up with the needed discharge pressures, so manufacturers are turning to grooved-barrel extruders or melt pumps on smooth-bore extruders to meet the needs. In addition, attention must be given to the screw design in order to create the needed discharge pressures.
