Patent number: 7074199Abstract: Chest compressions are measured and prompted to facilitate the effective administration of CPR. A displacement detector produces a displacement indicative signal indicative of the displacement of the CPR recipient's chest toward the recipient's spine. A signaling mechanism provides chest compression indication signals directing a chest compression force being applied to the chest and a frequency of such compressions. An automated controller and an automated constricting device may be provided for applying CPR to the recipient in an automated fashion. The automated controller receives the chest compression indication signals from the signaling mechanism, and, in accordance with the chest compression indication signals, controls the force and frequency of constrictions.Type: GrantFiled: September 12, 2001Date of Patent: July 11, 2006Assignee: Revivant CorporationInventors: Henry R. Halperin, Ronald D. Berger

Patent number: 6869409Abstract: An inflatable vest design for cardiopulmonary resuscitation (CPR) and for cardiac assist. The vest may include a belt that wraps around the chest of a patient, and a removable bladder that is placed against the chest and held in place by the belt. The inflatable bladder expands radially to first conform to a patient's chest, and to apply circumferential pressure to the thorax of the patient. By cyclically inflating the bladder, the vest can be used in CPR and cardiac assist treatments. In addition, alternative vest designs are disclosed showing removable bladders. These vest improvements lower the energy consumption and make smaller and portable cardiopulmonary resuscitation systems more practical.Type: GrantFiled: April 20, 1998Date of Patent: March 22, 2005Assignee: Revivant CorporationInventors: Neil S.

Patent number: 6827695Abstract: A method of processing a raw acceleration signal, measured by an accelerometer-based compression monitor, to produce an accurate and precise estimated actual depth of chest compressions. The raw acceleration signal is filtered during integration and then a moving average of past starting points estimates the actual current starting point. An estimated actual peak of the compression is then determined in a similar fashion. The estimated actual starting point is subtracted from the estimated actual peak to calculate the estimated actual depth of chest compressions. In addition, one or more reference sensors (such as an ECG noise sensor) may be used to help establish the starting points of compressions. The reference sensors may be used, either alone or in combination with other signal processing techniques, to enhance the accuracy and precision of the estimated actual depth of compressions.Type: GrantFiled: October 25, 2002Date of Patent: December 7, 2004Assignee: Revivant CorporationInventors: James Adam Palazzolo, Ronald D. Berger, Henry R. Halperin, Darren R. Sherman

Patent number: 6752771Abstract: A method and device are disclosed for inflating an inflatable vest to assist the heart in patients suffering from heart failure. The inflation of the vest is synchronized with on-set of the systole phase of the heart, when the left ventricular compresses to force blood out of the heart and through the aorta. The inflated vest compresses the patient's chest and increases the intrathoracic pressure. This increase in pressure assists the heart in moving blood out of the heart and through the aorta. In addition, the vest is arranged to leave the patient's abdomen free of restraint so that the increase in intrathoracic pressure due to the vest moves blood into the abdomen, and to allow the abdomen to dynamically recoil in response to the vest inflation. In addition, ECG signals from electrodes applied to the patient are processed to trigger the vest inflation in real time with the current heartbeat cycle, such that the vest inflation is triggered when the heart begins to contract.Type: GrantFiled: January 29, 2001Date of Patent: June 22, 2004Assignee: Revivant CorporationInventors: Neil S.
