  • Publication number: 20230338627
    Abstract: The invention relates to self-cleaning porous structures, e.g., layers or coatings, fabricated within, applied to, or deposited on a blood contacting surface of a medical device, to prevent activation and aggregation of platelets thereon. In certain embodiments, the layer or coating is composed of multi-layered fibers. The porous structure is applied to or deposited such as to form a permeable wall on the blood contacting surface. The blood travels into the wall and subsequently back out (reversing back into the lumen) during a cardiac cycle. Reversal flow is controlled during the diastole phase such that the backward flow repels the platelets and prevents their activation and aggregation and therefore, minimizes thrombus formation.

  • Publication number: 20230255560
    Abstract: Electrodes providing excellent recording and physical stability. Electrodes are disclosed that may include a plurality of small teeth that possess a novel design shape and orientation. The shallow and relatively long teeth run parallel to the rim of the electrode that presses against the patient’s skin. When the electrode is twisted onto skin, the tiny teeth penetrate the stratum corneum and move nearly horizontally under the stratum corneum, thus anchoring the electrode securely to the skin. The electrodes cause minimal discomfort to the patient since the small teeth do not extend to the pain fibers which are located in deeper layers of the skin. The electrodes may be fabricated in a variety of geometries including cylindrical, disk, and blunt bullet or top shapes. In some instances, the electrodes may be connected to detachable leads having magnetic properties.
