A coronary sinus guiding introducer utilized to introduce medical devices, such as electrode leads, into the coronary sinus of a human heart. This guiding introducer contains a precurved distal portion, which curves through an arc of about 50 to 150 degrees. Preferably, the distal portion contains a pair of generally coplanar curves, wherein the arc of the first curve is from about 20 to about 60 degrees and the arc of the second curve is from about 30 to about 90 degrees and wherein the second curve is generally coplanar with the first curve. In an alternative embodiment, the second curve curves out of a plane formed by the first curve from about 15 to about 90 degrees. In addition, preferably the guiding introducer is splittable. Also disclosed is a process for introducing medical devices through the lumen of the precurved, coronary sinus guiding introducer.

The invention provides exemplary devices and methods for increasing cardiopulmonary circulation when performing cardiopulmonary resuscitation. In one exemplary method, a patient's chest is actively compressed during a compression phase. At least some of the respiratory muscles are stimulated to contract during a decompression phase to cause an increase in the magnitude and duration of negative intrathoracic pressure during the decompression phase. In this way, the amount of venous blood flow into the heart and lungs is enhanced.

Stimulatory device and methods to enhance venous blood return during cardiopulmonary resuscitation

Exemplary devices and methods for increasing cardiopulmonary circulation when performing cardiopulmonary resuscitation. In one exemplary method, a patient's chest is actively compressed during a compression phase. The diaphragm is then stimulated to contract during a recovery phase to cause an increase in the magnitude and duration of negative intrathoracic pressure during the recovery phase. In this way, the amount of venous blood flow into the heart and lungs is enhanced.

A catheter for insertion in the ostium of the coronary sinus in the right atrium comprised of a main reinforced portion, an intermediate zone portion and a soft tip portion wherein a portion of the catheter is curved in a double curve, wherein the first curve is a first longitudinal curve, wherein the second curve is a second longitudinal curve, wherein the second longitudinal curve is curved in approximately the same direction as the first longitudinal curve and wherein the first and second longitudinal curves are generally coplanar.

Coronary sinus catheter

A catheter for insertion in the ostium of the coronary sinus in the right atrium comprised of a main reinforced portion, an intermediate zone portion and a soft tip portion, wherein a portion of the catheter is curved in a compound curve formed by a first and second curve, wherein the second curve may be curved in the same direction as the first curve or out of a plane formed by the first curve.
