A heart massager for substernal heart massage is disclosed. The heart massager has a heart-contacting member having a surface which is at least partially concave for contacting the heart, cushioning on the surface of the contact member, and a handle attached to the heart-contacting member for manually manipulating the massager. The partially concave surface allows the heart-contacting member to conform to the shape of the heart. The handle is substantially upright with respect to the surface of the heart-contacting member. The handle is significantly offset from a central portion of the heart-contacting member in the region where it attaches to the member. The cushioning covers substantially the entire surface of the heart-contacting member so as to form a solid surface. |

DETAILED DESCRIPTION The present invention is directed to a massager and a method both to be used to accomplish internal cardio-pulmonary resuscitation (CPR).
The massager is a manually operated cardiac compressor that is used to sustain the blood flow of the body during periods of cardiac arrest, and has various embodiments each of which allows for a minimal thoracic incision for the massager's safe, intrathoracic introduction and positioning.
The direct, intrathoracic heart massager comprises a heart-contacting member having a surface which is at least partially concave for contacting the heart, a handle means attached to the heart-contacting member for manually manipulating the massager, and, preferably, cushioning means on the surface of the contacting member.
The method for performing the heart massage comprises the following steps: providing a heart massager having a heart-contacting member connected to a handle and which member is at least partially concave for contacting the heart; making an incision into the skin at the intercostal space, preferably in the fourth intercostal space, between the left nipple and the lateral border of the sternum; surgically separating the intercostal space; inserting the heart massager through the intercostal space and onto the apex region of the heart; and then, periodically and manually pressing and releasing the handle so that the heart is alternately compressed and allowed to return to its non-compressed state.
Other objects, advantages and novel features of the present invention will become apparent in the following detailed description of the invention when considered in conjunction with the accompanying drawings.
