A grasping instrument designed to obtain tissue samples from the inner walls of the heart (endomyocardium) typically for histopathological examination. It is typically a flexible metal coil or plastic tube with a pair of scissors-like cups with cutting edges around their rims at the distal end which are operated by a handle attached at the proximal end. It is usually introduced percutaneously through the jugular vein or femoral artery (during catheterization). Acquired tissue samples are typically used for assessment of early rejection of a transplanted heart, cardiomyopathy and myocarditis diagnosis, or detection of antracycline cardiotoxicity. This is a reusable device.
A hand-held manual instrument designed primarily for non-dedicated grasping of devices, sponges and/or dressings during a procedure; it is neither intended for tissue manipulation nor endoscopic use. It has a scissors-like hinged design with ring handles and blades (non-cutting) that may be available in a range of sizes or designs. It may be intended for use at a specific anatomy. This is a reusable device intended to be sterilized prior to use.
