Surgical Notes

Users of multiple channel devices may occasionally choose not to use the biopotential leads. There is a recommended procedure for how to handle the unused leads to prevent surgical or electrical co...

DSI doesn’t recommend re-sterilizing re-gel syringes, because the sterilization process (EtO) will change the properties of the gel, which may negatively affect data collection. DSI cannot guarante...

The following are potential causes of rat hind limb paralysis: Prolonged occlusion of the abdominal aorta – this is generally not a factor if flow is eventually fully restored Too much glue used t...

Select a “luer-lock“ syringe of the proper diameter for the animal species. The opening should fit around the snout between the nares and the eyes. Remove plunger and cut off the finger portion o...

It may be necessary to remove an implant intact, such as when it may be reused in another animal (following cleaning and re-sterilization), or if there have been any signal quality concerns and the...

By: Dr. Craig Hassler, Battelle-Columbus, Columbus OH Good quality ECG recordings require proper lead placement technique. A technique developed and used at our lab meets the requirements for ease...

The design of the mouse pressure transmitter (PA-C10, HD-X11 and HD-X10) provides optimum performance when monitoring physiologic pressures in small laboratory animals. The extreme sensitivity of t...

The design of the small animal pressure transmitter (HD-S10, HD-S11 and HD-S21) provides optimum performance when monitoring physiologic pressures in laboratory animals. The sensitivity of the devi...

The design of the pressure implant provides optimum performance when monitoring physiologic pressures in laboratory animals. The sensitivity of the device is largely dependent upon the terminal end...

The attached document contains surgical supplies relevant for use with large animal DSI telemetry. A listing of supplies by device type is provided, as well as vendor and part number information. M...

All new iPRECIO infusion pumps shipped to an investigator are sterile and ready for implantation. DSI has developed procedures for cleaning and sterilizing iPRECIO pumps when returning them to DSI ...

Occasionally, following implantation of the DSI transmitter, an animal may experience poor wound healing and even extrusion of the transmitter. This situation can be avoided by using proper surgica...

The pressure sensors in DSI’s blood pressure transmitters are delicate instruments and can be easily damaged. Therefore, it is necessary to use proper care when handling the transmitters. Below are...

The PhysioTel HD product line utilizes an external suture rib made of a flexible material that has been demonstrated to be effective in securing the transmitter body to the body wall. The suture ri...
