Quality and Performance

Every sensor is manufactured to exacting quality standards to ensure reliability, durability and reproducible performance during operation.

Sensor Sterilization Sensors with product codes featuring the 'XP' suffix can be heat sterilized (autoclaved) 10 to 20 times unless indicated otherwise. The single fiber type sensor (MSF100XP) is recommended for single-use only.

Sensor Cables Unless otherwise indicated, standard sensor cables are manufactured from white flexible silicone tubing with an external diameter of 2.2 mm and standard length of 3m. For MRI or remote sensing applications, longer sensor cables can be manufactured to order (up to 8 m).

Needle Sensor Shaft Lengths Needle sensors can be supplied to order with shaft lengths of between 10 - 70 mm (standard length is 30 mm). Please contact Sales for custom requests.

 

Surface sensors

For microvascular blood perfusion monitoring from the surface of skin and organs. These sensors comprise a black plastic body providing right-angled blood perfusion monitoring. Surface sensors can be secured to skin using our double-sided adhesive rings. Since our surface sensors do not contain metallic components they are entirely compatible with MRI applications.

MSP100XP Standard surface sensor These robust and easy-to-handle sensors are ideal for making measurements of cutaneous blood perfusion anywhere on the skin surface.   Autoclaveable.
MSP110XP Digit surface sensor Specifically developed for measuring skin blood perfusion in the digits, the curved geometry of these sensors make them ideal for studying conditions such as Raynaud's disease.   Autoclaveable.
MSP300XP Miniature surface sensor (suturable) Small and lightweight, suitable for non-invasive skin monitoring and for semi-invasive monitoring from muscle and internal organ surfaces. Double sided adhesive rings are available for reliable tissue attachment; alternatively this sensor can be sutured onto the tissue.  Autoclaveable.
MSP310XP Miniature surface sensor (non-suturable) Small and lightweight, suitable for non-invasive skin monitoring and for semi-invasive monitoring from muscle and internal organ surfaces. Double sided adhesive rings are available for reliable tissue attachment.    Autoclaveable.

 

Needle sensors

For invasive or non-invasive tissue blood perfusion monitoring. These sensors utilize medical grade stainless steel.

MNP100XP Standard needle sensor For microvascular blood perfusion measurements in relatively inaccessible areas with limited clearance. (Typically positioned using an external clamp over soft tissues such as brain and muscle).     Approx. 19 gauge (~19G) surgical steel shaft. Custom shaft lengths available to order. Autoclaveable.
MNP110XP Fine needle sensor This micro-needle sensor has been developed for minimal tissue trauma during invasive insertion and is frequently used for measuring microvascular blood perfusion within skin, muscle, tumor, internal organ and brain tissues.     25 gauge (25G) surgical steel shaft Custom shaft lengths available to order. Autoclaveable.
MNP150XP Bent tip needle sensor Using this specially shaped sensor, blood perfusion within teeth and the gingiva can be measured to assess the viability of both tooth and gum. The bent tip can also facilitate access for monitoring blood perfusion in the oral and nasal mucosa. (Typically positioned using an external clamp).    Approx. 19 gauge (~19G) surgical steel shaft. Custom shaft lengths and configurations available to order. Autoclaveable.

 

Specialized sensors

For chronic microvascular blood perfusion monitoring from the same tissue site, we offer an implantable, light and highly flexible single fiber (SF) sensor. The SF sensor consists of a thin, 0.5mm diameter plastic (polymethyl methacrylate) fiber. Single fiber (SF) sensors require a special adapter (the 'MSF Driver') for each instrument channel occupied by an SF sensor. Since the SF sensor and the MSF Driver are entirely polymer based, they are suitable for use in MRI environments.

MSF100XP Single-fiber implantable sensor This light and flexible sensor has a 0.5mm diameter and a standard length of 30cm. Particularly useful for chronic implantation the MSF100XP can be directly inserted into tissue using a standard 22G i.d. cannula. The extra light coupling bead minimizes the total weight of the implanted sensor. Flow measurements are made by attaching the MSF Driver (MSFD below).    The MSF100XP is a disposable sensor not suited to autoclave sterilization.

MSFD XP Connecting adapter for the MSF100XP  implantable sensor The MSF Driver is a precision-machined coupling system designed to interface with the MSF100XP sensor and the instrument. The MSF100XP sensor coupling bead is locked into position by a simple turn of the MSF Driver head.   Manufactured from black plastic and containing no metallic parts, the MSF Driver can be used with complete confidence in MRI environments.
