Abstract: Methods, apparatuses, and systems for making prepregs are disclosed. A method may include depositing a resin material onto a surface of a fiber bed and forming a number of discrete resin regions thereon. A distance between the resin regions may be measured to provide desired exposed portions of the surface to facilitate permeation of air through the exposed portions of the surface in a direction perpendicular to a plane of the fiber bed during a curing process of the prepreg.

Abstract: The present invention provides an advancement in the art of cardiac pacemakers. The invention provides a novel and unobvious pacemaker system that comprises at least one pacemaker and that is, to a large extent, self-controlled, allows for long-term implantation in a patient, and minimizes current inconveniences and problems associated with battery life. The invention further includes a mechanism in which at least two pacemakers are implanted in a patient, and in which the pacemakers communicate with each other at the time of a given pacing or respiratory event, without any required external input, and adjust pacing parameters to respond to the patient's need for blood flow. The invention further provides a novel design for a pacemaker in which the pacemaker electrode is connected to the pacemaker body by a lead that is configured to allow the pacemaker to lie parallel to the epicardial surface and to reduce stress on the pacemaker and heart tissue.
