USER EXPERIENCE & USABILITY

  Whatever the medical device is, the final aim of the development process is to provide user a product with an acceptable risk/benefit ratio. On one hand we seek to lower the medical device related risk. On the other hand, we try to reach the highest levels of efficacy. A common and important point of both elements of this ratio that drives the development of medical devices is the usability. First, regarding the risk, a recent FDA recall study shown that 44% of medical device recalls are due to design problems, and user errors are often linked to the poor user experience. On the other side, treating a patient with a medical device frequently requires a more complex sequence of actions than the “simple” delivery of a drug. Consequently the efficacy of a medical device is closely linked to the product usability. Usability and user experience are the key ingredients to get an acceptable risk/benefit ratio.

OUR VISION


At Sophysa, we believe that usability and user experience of medical devices should never be a brake to patient management. That is why in every development we do, we keep challenging the status quo to provide you a unique user experience enabling you to be totally dedicated to your patient. Over the last 40 years, in accordance with our vision, we put all our effort in developing ground-breaking solutions improving user experience for a better patient management in the fields of CSF Management and Neuro ICU. Here are some concrete and well-known example of this dedication to usability : The Sophy® valvewhich was the first adjustable valve in the World allowing non-invasive adjustment of pressure settings, to match an individual patient's changing clinical needs. The Polaris® valve, the first adjustable valve with a magnetic lock, specifically designed to resist unintentional changes in pressure settings – a major milestone in adjustable valve safety. Polaris® offers the patient an unequalled security against the clinical risks associated with those dysadjustments. The Pressio®2 monitoring system, a user-friendly Intra-Cranial Pressure and Intra Cranial Temperature monitoring system for neurosurgery and neurotrauma, bringing the continuous ICP and ICT monitoring to a new level of performance and ease of use.

The safety of adjustable valves has become a major concern for neurosurgeons because of the growing use of electromagnetic devices in daily life and the development of high power MRI (3 teslas). Indeed, these devices are liable to modify the selected pressure accidentally, with the risk of disrupting CSF drainage and causing serious complications for the patient. The Polaris® valve is a major breakthrough for the safety of patients fitted with adjustable valves.
Its exclusive locking mechanism enables it to resist: Direct knocks to the valve; Everyday magnetic fields; Magnetic Resonance Imaging (MRI), up to 3 teslas. It offers the patient an unequalled security against the clinical risks associated with pressure dysadjustments.
The adjustable Polaris® valve is a major breakthrough for the safety of patients thanks to the patented self-locking system of the rotor. This magnetic lock has been designed to resist unintentional operating pressure changes due to knocks or exposure to magnetic fields, especially during MRI examinations. It offers the patient an unequalled security against the clinical risks associated with those dysadjustments. The Polaris® Magnetic Lock
The Polaris® Magnetic Lock is based on the permanent reciprocal attraction of two mobile micro-magnets of opposite polarity. This “magnetic lock" holds the rotor in the selected position, thus preventing any accidental change in operating pressure if the valve is exposed
to magnetic fields. In fact, in the presence of a standard magnetic field (unidirectional) the two micro-magnets are attracted in the same direction. So only one of the two magnets moves in the direction of the field, while the other remains locked. Changing the operating pressure of the valve first requires the simultaneous unlocking of the two micro-magnets in the valve by a specific magnetic key. The rotor can then turn freely on its central axis. Normal position
Security position
Valve subjected to a knock or to a magnetic field Adjustment position
with specific magnetic key Direct pressure reading is obtained using the Adjustment Kit Compass: the Compass needle is aligned with the position of the magnetic rotor.
In addition to the standard model (30-200 mmH 2O), Polaris® also offers a unique special pressure range :
one low pressure valve and two high pressure valves. Thus a choice is provided, depending on the experience of the practitioner, to meet very specific clinical needs.

The device incorporates a ball-in-cone mechanism, well known for its precision and reliability.
It is placed downstream of a CSF shunting valve for the treatment of hydrocephalus, giving it additional resistance depending on the position of the patient. This makes it possible to limit the siphon effect during CSF drainage when the patient stands up.

A tantalum weight ball presses on a ruby ball, which occludes the aperture for the passage of the CSF.
When SiphonX® is in the vertical position, the ruby ball is subjected to the full weight of the tantalum ball, occludes the anti-siphon aperture and the device adds 200 mmH 2O to the operating pressure of the valve.
When SiphonX®is in the horizontal position, the ruby ball is not subjected to the weight of the tantalum ball and so does not occlude the aperture of the anti-siphon device.
In this horizontal position, the device is therefore open and does not add any additional resistance to the operating pressure of the valve.
For all intermediate positions, SiphonX® adds a resistance which depends on the angle of inclination.
By design SiphonX®is not affected by the implantation height relatively to cerebral ventricules.

The Adjustable Sophy® Mini valve is a high-precision device of unparalleled simplicity. The principle of the Sophy® valve resides in the variation in pressure exerted on a ball by a semi-circular spring at various points along its circumference. The spring is attached to a magnetic rotor which position can be non-invasively changed using an adjustment magnet. A series of indentations allows a variety of positions to be selected, each position representing a different pressure setting.
Direct pressure reading is obtained using the adjustment kit compass: the compass needle is aligned with the position of the magnetic rotor.
  In addition to the standard model (30-200 mmH 2O), Sophy® Mini SM8 also offers a unique special pressure range: one low pressure valve and two high pressure valves. Thus a choice is provided, depending on the experience of the practitioner, to meet very special needs The Sophy® Mini SM8-140 and SM8 can be associated with SiphonX®, an anti-siphon device, which adds 200 mmH 2O in vertical position.

The Pulsar® valve is a monopressure valve for cerebrospinal fluid drainage. Its principle is based on the play of a silicone membrane, calibrated in low, medium or high pressure, ensuring a proximal regulation of the CSF flow through the shunt system. The Pulsar® valve has an anti-reflux system, offers the possibility to test the shunt patency and gives access to CSF.
