Experiments on isolated organs and tissues require the use of clamping devices for locating cannulae, probes and sensors in the correct position relative to the preparation. With the reduced size of modern murine preparations there is now a need for more sensitive devices, light in weight, freely adjustable, and requiring minimal force for adjustment.

HSE-HA mini holders consist of arms of different lengths which carry a ball or a wire clip (eye) on the ends. Several arms can be clipped together and the ball joint allows the holder to be moved into any configuration. Arms with special terminations are available to carry electrodes, mount flow probes or support intracardial balloons. A high-flexibility mount for crystal pickups maintains contact with the surface of the organ during its intrinsic movement.

All holder elements are made from stainless steel. The special design of ball joint ensures minimum size and permits perfectly smooth operation without any trace of spring-back. Mini holders remain rigid while carrying weights up to a few grams and are suitable for supporting tubing and small components.

Mini ball joint holders are ideal for use on small operating tables and especially inside small organ chambers where space is extremely limited. There are complete kits available for measuring isovolumetric LVP balloon pressure in mice hearts, ECG detection from mice hearts and stimulation of mice hearts. Other possibilities are: mounting of small flow probes on open chest experiments in mice or rats, mounting of cannulas on small isolated organs like liver, kidney, lung, hearts. A lot of further applications are possible. For self-created applications the following parts can be used.

Holding Elements receive 5 mm Mini Balls. This Universal Holder is used to allow non-Mini Ball Products to mate with Mini Ball components. The bar can be bent to wrap around an electrode or be used as a brace to strap an electrode into place.
