23 Jul Myocardial mechanical stimulation device constructed through tissue engineering
Abstract
The invention discloses a myocardial mechanical stimulation device constructed through tissue engineering, which belongs to the technical field of biomedicine. In the device, annular myocardial cells constructed by using a tissue engineered method are mechanically stimulated in a way similar to natural myocardial beating. The device consists of a motor, a transmission system, a bracket and a mechanical stimulation part. The device can be used for applying mechanical stimulation of 1-5 Hz in frequency and 10 percent amplitude to a constructed annular myocardial cells-collagen structure of which the circumference is about 2-12 centimeters. The myocardial cell-collagen structure can be used for inducing spontaneous beating myocardial cells under the action of the mechanical stimulation to realize consistent beating; and meanwhile, the development level of the myocardial cells and the contraction force of spontaneous beating can be increased.
