3D printing can reduce heart valve leaks: Here’s how

Doctors can use 3D printing and computer modeling to predict paravavular leak (PVL) in patients who are undergoing transcatheter aortic valve replacement (TAVR), according to new research from the University of Minnesota. One of the common risks associated with TAVR is valves not fitting which can cause PVL. A recent study conducted by cardiovascular fellow

Danfoss Power Solutions adds high-flow proportional valves to PVG portfolio

Danfoss Power Solutions (Ames, Iowa) recently added two new high-flow proportional valves to its PVG portfolio. The new valves, PVG 128 and PVG 256, are designed to be easily integrated with the company’s current high performance proportional valves. They add modularity from low to high hydraulic flow in the same valve stack. High-flow valves are used

MD&M West: Here’s what you may have missed

MD&M West is one of the largest medical device manufacturing events in the world, so it’s easy to lose your way on the show floor. Even if you were in Anaheim, Calif., for the February 2018 event, you may have missed a lot. From Omron to Micromo to MedPlast to Apex Motion Control, WTWH Media

Freudenberg Medical launches new hemostasis valves

Freudenberg Medical has launched several new hemostasis valves for interventional and diagnostic catheters. HyperSeal and CertuSeal hemostasis valves have been added to the FlexSeal valve line that the company released last year. Freudenberg Medical also added its new HyperSeal Introducer Sheath with Hydrophilic Coating to the FlexSeal Introducer Sheath for large bore procedures. The catheters

Clippard announces newest high flow proportional electronic valves

Clippard (Cincinnati) recently announced its newest DVP series proportional solenoid valves, which the company describes as precision-built two-way control valves. The valves use a unique, patented valving principle and were designed as the next generation of the original EV line of Clippard “Mouse” valves. The newest valves have a life of over a billion cycles; a

Is this the key to rapidly manufacturing heart valves?

Nanofiber fabrication may be the key to rapidly manufacturing heart valves with regenerative and growth potential, according to new research from Harvard University’s Wyss Institute for Biologically Inspired Engineering. A research team led by Kevin Kit Parker created a valve-shaped nanofiber network that replicates the mechanical and chemical properties of the native valve extracellular matrix (ECM).

Bio-Chem, Koganei announce Opus solenoid actuated rocker valve

A co-development effort between Bio-Chem Fluidics and Koganei Corp. has resulted in the Opus solenoid actuated rocker valve – specifically designed for clinical diagnostics and life science applications. Bio-Chem and Koganei announced the release of the Opus rocker valve on July 25. The Opus is a modification of the existing Koganei PVR valves. It is about half the size

Qosina adds 2 tuohy borst adapters to its line

Qosina recently announced 2 new tuohy borst adapters. One adapter (No. 80460) features a female luer lock sideport connector. The other (No. 80461) has a 6-in. DEHP-free PVC sideport tube to a female luer lock connector. Both tuohy borst adapters are available to fit 0 to 9 French guide wires. They have proprietary tri-cut silicone valve

Mechanical heart valves are so loud that they cause insomnia

A quarter of patients with mechanical heart valves claim that the valves disturb their sleep, according to a new study. “For some patients, the closing sound of their mechanical heart valve reduces their quality of life, disturbs their sleep, causes them to avoid social situations and leads to depression and anxiety,” said Kjersti Oterhals, a

Injectech adds new Y-connectors

Injectech (Fort Collins, Coloroado) has announced new barbed Y-connectors. These products will join Injectech’s already established line of tube-to-tube connectors in 2017. Injectech will be debuting the Y-Connectors at the upcoming MD&M West trade show in Anaheim, Calif., Feb. 7–9. Injectech will be at Booth 4079. Injectech will be at Booth 4079 and invites attendees

Predictions on the future of transcatheter mitral valve replacements

David Novotny, Senior Vice President Medical Device and Diagnostics, Novella Clinical The standard of care for moderate and high-risk patients with severe aortic stenosis – transcatheter aortic valve replacement (TAVR) – may soon be matched by transcatheter replacement of a mitral valve, a market potentially four times the size of TAVR. Developments for TMVR and upcoming clinical
