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.

Abstract: Continuous insect-based biowaste processing apparatus has a tubular drum; a drive for rotatably driving the drum; a shaftless screw conveyor fixedly connected to an inner surface of the drum; circumferentially spaced cantilevered blades that (a) are connected to the inner drum surface and (b) each longitudinally extends throughout the drum; and a mechanism for introducing a conglomerate portion that includes biowaste and insect larvae into the drum interior. The screw conveyor is subdivided into longitudinally spaced chambers for the introduced insect larvae, each of the chambers being defined by two adjacent flights of the screw conveyor and by the blades. The size of the insect larvae progressively increases within a more distally located rearing chamber. Two or more blades firmly hold and unify the conglomerate portion throughout its residing time within the drum interior while being distally conveyed.

Abstract: Locking mechanism and safety latch for multi-purpose apparatus. The apparatus includes at least a first tool and a second tool. Each tool can rotate between open position and closed position. The locking mechanism includes a rotatable elongated lever, connected perpendicularly to a locking bar. The mechanism is switchable among at least: a first position in which the mechanism holds or locks in place both the first tool and the second tool when they are in closed positions; a second position in which the mechanism holds or locks in place both the first tool and the second tool when the first tool is in open position and the second tool is in closed position; a third position in which the mechanism holds or locks in place both the first tool and the second tool when the first tool is in closed position and the second tool is in open position.

Abstract: The present invention provides a novel design for sheaths intended for medical procedures. The sheath includes structures that anchor the sheath in a cavity or space when deployed but are at the same time retractable such that the sheath can be removed without tearing the tissue defining the space.

Abstract: An open coiled pacemaker lead is provided that has improved structural stability and functional life in vivo. The open coiled lead includes an electrically conductive material that is coated or covered by a thin layer of electrically insulative material. The coated coiled lead has adequate spacing between adjacent coils, and has a lumen of sufficient diameter, to allow for infiltration of biological connective tissue onto the surface of the coated coil when maintained in vivo for a sufficient amount of time. Infiltration of the connective tissue essentially uniformly along the entire coiled lead strengthens and lengthens the functional life of the coated coil lead.

Abstract: A multi-purpose tool or apparatus includes multiple mechanical tools. In one implementation, the multi-purpose tool includes an elongated handle, a folding axe, and a folding shovel or spade, as well as a hammer or hammer-head. The folding axe is foldable between an open position and a closed position. The folding shovel is foldable among three positions, which are a closed shovel position, a 90-degree open shovel position, and a 180-degree extended shovel position. The elongated handle is hollow and includes an elongated cavity. A folding saw, as well as a knife and a sheath to protect the knife, are stored within the elongated cavity and can be removed therefrom.

Abstract: To provide for higher data rates, a wireless back haul network for connecting small cell base stations to a core network can be implemented using full-duplex over single channel communications. The difficulty with full-duplex over single channel communications, and the reason why it has not become common place in wireless and mobile communication standards to date, is the significant interference that the receiver of a full-duplex communication device will generally experience from the full-duplex communication device's own transmitter transmitting over the same channel that the receiver is to receive signals. This interference is referred to as self-interference because the interference experienced by the receiver originates from its own paired transmitter. The present disclosure describes embodiments of an apparatus and method that provide sufficient self-interference cancellation in a compact and power efficient manner for a small cell wireless backhaul network.

Abstract: The present invention provides a fully intrathoracic artificial pacemaker. The pacemaker is of sufficiently compact size to allow for implantation of both the electrode and the power source within the chest cavity. In exemplary embodiments, a screw-type electrode is used for connection to heart tissue, and a relatively short lead is used to connect the electrode to a battery unit, which can comprise electronics for control of the pacemaker. An assembly for implanting the pacemaker, as well as methods of implanting the pacemaker, are disclosed. In embodiments, the device is designed as a fetal pacemaker.
