Surgical-invasive laser Doppler probes

 Print E-mail

Probes intended for surgical-invasive blood perfusion measurements. In addition, probes with disposable microtips are available for chronic measurements in for example muscle.

A selection of probes is presented below. Specific dimensions can be viewed in the laser Doppler probe brochure.

Please contact us if you cannot find a suitable probe for your particular application. 
 

Note: The 300-series probes are designed to fit the PeriFlux PF 2B and PF 3. The 400-series probes are designed for the PeriFlux System 4000 and PeriFlux System 5000.

 probe 402

PROBE 402 (302) Needle Probe

Intended for acute invasive measurements. The tip (diam. 0.45 mm) may be introduced directly into the tissue to the desired depth or inserted through a 22 G/0.6 I.D. cannula.
See also PROBE 411 and PROBE 418 with Microtips.
Fibre separation: 0.15 mm.

probe 404

PROBE 404 (304) Suturable Angled Probe

The probe is designed to be sutured onto a flap. The low profile allows easy removal when used with buried flaps. The probe is made of epoxy to be rigid and flexible.
Fibre separation: 0.25 mm.

probe 407

PROBE 407 (307) Small Straight Probe with Miniholders

The soft, flexible design of the fibre line reduces the influence of artifacts from moving subjects. The probe fits into different types of small probe holders, miniholders, suitable for different tissues.
Fibre separation: 0.25 mm.
PH 07 The Miniholder has a thin latex sheet that adheres to wet surfaces. Intended for use on liver, kidney and intestine. Diameter 20 mm.
PH 07-6 Glued to hard tissues like teeth and bone. The low, smooth profile allows the miniholder to be glued onto a tooth and left in place for extended periods, thus enabling repeated measurements on the same vascular bed.
Diameter 4 mm, height 2.5 mm.

probe 411

PROBE 411 (311) Needle Probe for Micromanipulator

Intended for acute invasive measurements. The support is designed to fit in a micromanipulator or laboratory stand for exact positioning. The tip is thin (0.45 mm) for easy penetration of tissue, for example animal brain.
See also PROBE 402.
Fibre separation: 0.15 mm.

 probe 418

PROBE 418-x (318-x) Master Probe

The probe is designed for simple connection and disconnection of the microtip. Two different versions are available depending on tissue property and fibre length.
PROBE 418-1 (318-1) Used for normal tissue.
PROBE 418-2 (318-2) Used for very dark tissue (e.g. kidney). Also used with extra long microtips.

MT B500-0 Straight Microtip
Intended for measurements in tissues. The 0.5 mm flexible microtip can be inserted into the tissue with a 22 G/0.6 I.D. cannula.
The tips are available with lengths of 80, 120 and 240 mm. Other lengths are available.
Maximum lengths: wavelength 633 nm: 3000 mm, wavelength 780 nm: 1000 mm.

MT A500-0 Straight Microtip with Slanted Tip
Intended for measurements in tissues. The distal end of the tip has been polished with a slight angle to improve the optical properties. This results in a higher signal-to-noise ratio than ordinary straight microtips. The 0.5 mm flexible microtip can be inserted into the tissue with a 22 G/0.6 I.D. cannula.
The tips are available with lengths of 80, 120 and 240 mm. Other lengths are available.
Maximum lengths: wavelength 633 nm: 1200 mm, wavelength 780 nm: 300 mm.

 probe 420

PROBE 420 (320) Flexible Straight Probe

Suitable for measurements in parenchyma. It fits into commercially available skull screws. The probe can also be introduced into muscle or other tissues using a cannula.
Fibre separation: 0.25 mm.
