Cannula Implant Guides

  • Improves Adhesion and Stability During Implantation
  • Compatible with Ø1.25 mm and Ø2.5 mm Fiber Optic Cannulae with ≥5 mm Length
  • Ø3.8 mm (OGL) or Ø5.1 mm (OGF) Mounting Surface with Grooved Ring for Dental Cement
  • Lightweight Surgical Titanium Construction (≤0.11 g)
  • Weep Holes for Glue and Epoxy to Secure a Cannula
  • Compatible with Stereotaxic Cannula Holders

These Cannula Implant Guides are designed to provide guidance and stability for a fiber optic cannula during an implantation procedure. The bottom surface of each implant guide features a roughened surface and circular groove (see image to the right) that increase the surface area available to dental cement and improves adhesion to the specimen. A 1.6 mm long protrusion on the implant guide helps stabilize the guide when implanted. Each implant is constructed using lightweight surgical titanium (≤0.11 g) which can be sterilized prior to use.

For best results when implanting a cannula, the OGL and OGF should be used with a cannula holder and stereotaxic guidance equipment. To affix the cannula within the implant guide, first insert the cannula into the receptacle of the implant guide. Then, add a small amount of cement or epoxy to the cannula via the two Ø0.8 mm weep holes (see image above). Finally, attach the cannula ferrule to an XCL (Ø1.25 mm ferrule) or XCF (Ø2.5 mm ferrule) cannula holder (see image above).

The OGL implant guide is compatible with our standard Ø1.25 mm cannulae (ceramic and stainless steel) and the OGF implant guide is compatible with our standard Ø2.5 mm cannulae (ceramic and stainless steel). When assembled, the length of the protruding fiber is reduced by 1 mm (Item # OGL) or 2 mm (Item # OGF); therefore, these implant guides cannot be used with our 2 mm long cannulae. Additionally, due to the fiber separation distance, the implant guides cannot be used with our dual-core cannulae.

The RJ1 rotary joint has terminated ends and accepts a wide variety of FC/PC patch cables.

1x1 Rotary Joint for FC/PC Multimode Patch Cables

  • Rotary Joint Protects Against Fiber Damage Caused by Moving Specimen
  • Consistent Performance Over 400 - 700 nm Wavelength Range
  • Low Transmission Variation During Rotation
  • Recommended for ≥Ø200 µm Core, 0.22 to 0.50 NA Patch Cables
  • Tested and Designed for Use with a Multimode Laser or Fiber-Coupled LED

Thorlabs' RJ1 1x1 Rotary Joint for FC/PC Multimode Patch Cables is a single input and output rotary joint with low rotational variation. Designed for use in optogenetics, the rotary interface allows patch cables to rotate freely when attached to a moving specimen, reducing the risk of both fiber damage and intensity fluctuations. The input and output patch cables are not permanently attached to the rotary joint, and, as a result, can be selected with a specific core size, NA, and jacketing type to optomize an experiment. This also allows cables to be easily replaced if fibers are damaged. For best performance, we recommend using multimode fibers with a core diameter ≥Ø200 µm and NA between 0.22 to 0.50. Thorlabs can provide custom rotary joints that are aligned and optimized using other patch cables or light sources; please contact Tech Support with inquiries.

Optogenetics Selection Guide

Thorlabs offers a wide range of optogenetics components; the compatibility of these products in select standard configurations is discussed in detail here. Please contact Technical Support for assistance with items outside the scope of this guide, including custom fiber components for optogenetics.

 

Single-Site Stimulation

One Light Source to One Cannula Implant

The most straightforward method for in vivo light stimulation of a specimen is to use a single fiber optic with a single LED light source. The single wavelength LED is powered by an LED driver, and then the illumination output is fiber-coupled into a patch cable, which connects to the implanted cannula. See the graphics and expandable compatibility tables below for the necessary patch cables and cannulae to create this setup. To choose the appropriate LED and driver, see below or the full web presentation.

Bilateral Stimulation

The ability to accurately and simultaneously direct light to multiple locations within a specimen is desired for many types of optogenetics experiments. For example, bilateral stimulation techniques typically target neurons in two spatially separated regions in order to induce a desired behavior. In more complex experiments involving the simultaneous inhibition and stimulation of neurons, delivering light of two different monochromatic wavelengths within close proximity enables the user to perform these experiments without implanting multiple cannulae, which can increase stress on the specimen.

Bilateral stimulation can be achieved with several different configurations depending on the application requirements. The sections below illustrate examples of different configurations using Thorlabs' optogenetics products.


Option 1: One Light Source to Two Cannula Implants Using Rotary Joint Splitter

Thorlabs' RJ2 1x2 Rotary Joint Splitter is designed for optogenetics applications and is used to split light from a single input evenly between two outputs. The rotary joint interface allows connected patch cables to freely rotate, reducing the risk of fiber damage caused by a moving specimen. See the graphic and compatibility table below for the necessary cables and cannulae to create this setup. For LEDs and drivers, see below or the full web presentation.

Option 2: One or Two Light Sources to Two Cannula Implants

If the intent is for one LED source to connect to two cannulae for simultaneous light modulation, then a bifurcated fiber bundle can be used to split the light from the LED into each respective cannula. For dual wavelength stimulation (mixing two wavelengths in a single cannula) or a more controlled split ratio between cannula, one can use a multimode coupler to connect one or two LEDs to the cannulae. If one cable end is left unused, the spare coupler cable end may be terminated by a light trap. See the graphic and compatibility table below for the necessary cables and cannulae to create this setup. For LEDs and drivers, see below or the full web presentation.

Two Light Sources into One Dual-Core Cannula Implant

For bilateral stimulation applications where the two cannulas need to be placed in close proximity (within ~1 mm), Thorlabs offers dual-core patch cables and cannulae that are designed for this specific application. Each core is driven by a separate light source, enabling users to stimulate and/or supress nerve cells in the same region of the specimen. See the graphic and compatibility table below for the necessary cables and cannulae to create this setup. For LEDs and drivers, see below or the full web presentation.
