Wireless blood pressure sensor implantation in sheep: A detailed technique
Animal Models and Experimental Medicine, EarlyView.Twelve adult sheep underwent wireless blood pressure sensor implantation. The procedure lasted an average of 36 min, with mean systolic and diastolic blood pressures of 93 ± 6 and 65 ± 5 mmHg, respectively. This rapid, minimally invasive protocol is a powerful platform for cardiovascular device development.
