Surgeons have developed new minimally invasive surgery (MIS) techniques and instruments so that procedures that would previously have required a large incision can now be performed through a tiny 10mm cut.

The researchers used a torque sensor to measure the force of the palpations.

Currently this catheter method requires the use of three different devices, which are inserted into the heart in succession: one to map the heart's signals and detect the problem area, a second to control positions of therapeutic actuators and their contact with the epicardium, and a third to burn the tissue away.

The device is designed to deliver critical, high quality information - such as temperature, mechanical force, and blood flow - to the surgeon in real time.

The  pre-calibrated amplifier eliminates the need to calibrate with weights.

The system includes base, vertical support, bath support, micromanipulator block, micro- manipulator handle, muscle  supports rods, 1 pr/feet for rings, 25 μm and 100 μm Stainless Steel (3 m), 1 pr/hooks, 20 clips for strips, single myograph  bath and the TRN001 transducer.

iWorx offers 4-channel (M4) or single-channel (M1) Myograph systems from Radnoti Glass Technology. These systems are designed for researchers performing contractile force studies on small ring samples with sizes ranging from 60 mm to over 1 mm in diameter. Examples include mouse aortic rings and small intestinal ring samples as well as micro-vessel preparations like mesenteric arteries.The Myograph systems include myograph chambers with transducers and amplifiers, a base with sliding wrist rest, temperature controllers, stands, tubing kits and all other essential items to conduct an experiment.iWorx offers a myograph normalization module (LS-20NM) which calculates the optimal pretension settings for each sample prior to conducting an experiment.
