When studies connected with the production of experimental hypertension were undertaken, work in this field was carefully considered and the method of Goldblatt adopted.1 In brief, this consists of partially occluding the renal artery with a small metal clamp. By this method it is possible to produce in animals marked hypertension which persists for a long time. Dogs were chosen as the most suitable experimental animals, and Goldblatt clamps as originally designed were employed. In studying the method of application of the Goldblatt clamp, one of us (Glenn) felt that the clamp holder was not only unnecessary but unsurgical, as its use presupposed an approach larger than a successful application of the clamps warranted. Studies were therefore undertaken in an effort to devise a more suitable method. The results, as embodied in the following detailed operative procedure, are based on numerous postmortem dissections as well as on the successful
