Traditionally, skin biopsy specimens obtained from animals required anesthesia or manual restraint of the animal being sampled. To avoid the risks associated with restraint in many species, a projector biopsy instrument was developed to obtain skin tissue samples from a variety of species.
The ability to obtain tissue samples from wild animals has significantly enhanced conservation efforts relating to genetic analysis and medical surveillance. Samples obtained with this biopsy dart have been used successfully for tissue culture procedures. This method of tissue sample collection can provide a safe and convenient method of obtaining sample specimens from a wide variety of wild and free-ranging mammals. Negligible bleeding occurs after the sample is collected, and no treatment of the animal is necessary. This instrument has been tested on orangutans (Pongo pygmaeus), gorillas (Gorilla gorilla), lions (Panthera leo), zebra (Equus burchell), and patas monkeys (Erythro-cebus patas). Full size biopsy sample are collected 98% of the time when the syringe makes contact in a well-muscled area of the animal.
The biopsy syringe can be fired from any of Cap-Chur Equipments CO2 or Powder fired Projectors. 3cc or 4cc Syringes are the more commonly used syringes sizes. The biopsy syringe can be fitted to a crossbow, jab-poles or arrow shaft by use of Cap-Chur Arrow Adaptors. The biopsy syringe has also been used to collect tissue samples from large fish brought along side boats.
