PhD (“push, hold, deliver”) polycarbonate haemostasis control valve

Merit Medical has announced the launch of its PhD (“push, hold, deliver”) polycarbonate haemostasis control valve, now available in the USA.

The dual-seal PhD device allows operators to manipulate the valve with one hand by pressing down on the cap, keeping the other hand free for the insertion and withdrawal of diagnostic/interventional devices, according to a company press release. Its two seals—a primary compression seal and a secondary polyisoprene push and release bleedback seal—help physicians minimise blood loss without restricting device movement. The PhD allows for pressure injections up to 400 psi, accommodates devices up to 7.3F, and features a clear body that provides unobstructed visibility.

The PhD device has been available to European markets since 2014. There, it has seen significant success, with unit sales averaging 34% year-over-year growth. In the USA, Merit will offer the device as a stand-alone or in combination with Merit’s suite of leading inflation devices and custom kits. Merit will also offer optional sidearm extension tubing that creates additional space between the valve and connected devices.

The commercial launch of the PhD device follows the late 2018 reveal of Merit’s basixTAU, a first-of-its-kind inflation device featuring a fold out handle that can increase the speed of inflations and deflations. The basixTAU inflation device provides greater versatility and ease of use, while reducing rotational force by up to 67%. It is also designed with a clear barrel for visibility and an easy-to-read luminescent analogue display suitable for use in low-light procedures. The 20 mL device can achieve a maximum pressure of 30atm.
