Using DSI PhysioTel® Transmitters to study physiological parameters in large animals, such as primates, sheep, horses, cattle and others, provides researchers flexibility, reliability and ease. DSI offers different implantable transmitters to measure different parameters including pressure and activity; temperature and activity; biopotentials and activity; as well as transmitters that measure a combination of pressure, biopotentials, temperature and activity.
DSI implantable telemetry transmitters are used in large animal studies such as cardiovascular safety profile of almotriptan, hypertension induced by blockade of ETB receptors in conscious nonhuman primates, early physiological abnormalities after simian immunodeficiency virus infection and numerous other studies.
All of DSI’s PhysioTel® Transmitters are implantable and capable of measuring activity. The design of the transmitter shape allows for subcutaneous or intraperitoneal placement and PhysioTel® transmitters can be re-sterilized between uses, extending their implant life and reducing costs.
| The PhysioTel® PA series transmitters measure pressure and activity in large animals. A specially designed pressure transmission catheter transfers pressure from the tip of the catheter to a pressure sensor located in the transmitter body. Examples of pressures measured with PhysioTel® PA series transmitters include arterial, ocular, uterine, penile, bladder, pleural and left ventricular. Other parameter data such as heart rate, systolic, diastolic and mean pressure can also be collected. The PhysioTel® PA-D70 model is used in large animals. |

| The PhysioTel® TA series transmitters measure temperature and activity in small animals. Researchers find these transmitters ideal for studies requiring long-term stability. The long battery life and exceptional reliability of PhysioTel® TA series transmitters reduce operating expenses and allow for extended research protocols in aging, chronobiology and other studies without the need for repeat surgery. The PhysioTel® TA-D70 model is used in large animals. |

| The PhysioTel® EA, CA, ETA and CTA series transmitters measure biopotentials such as ECG, EEG and EMG as well as temperature and activity in small animals. These transmitters have flexible leads similar to those used in heart pacemakers, extending from the transmitter body. Each lead consists of a helix of special stainless steel wire covered with an insulating layer of silicone tubing. Once the silicone tubing is removed, the tips of the leads serve as sensing electrodes. The PhysioTel® CTA-D70 model is used in large animals. |
|
| The PhysioTel® Multiplus series transmitters measure combinations of pressure, biopotentials, temperature and activity. These transmitters are capable of measuring multiple physiological parameters simultaneously. The PhysioTel® D70-EEE, D70-PCT, D70-PCTP and D70-CCTP models are used in large animals. |
