Abstract: Techniques for controlling one or more modular circuits (“satellites”) that are intended for placement in a subject's body. The one or more satellites are controlled by sending signals over a bus that includes first and second conduction paths. Also coupled to the bus in system embodiments is a device such as a pacemaker that provides power and includes control circuitry. Each satellite includes satellite circuitry and one or more effectors that interact with the tissue. The satellite circuitry is coupled to the bus, and thus interfaces the controller to the one or more effectors, which may function as actuators, sensors, or both. The effectors may be electrodes that are used to introduce analog electrical signals (e.g., one or more pacing pulses) into the tissue in the local areas where the electrodes are positioned (e.g., heart muscles) or to sense analog signals (e.g., a propagating depolarization signal) within the tissue.
Abstract: Implantable pressure sensors and methods for making and using the same. A feature of of at least some of the subject pressure sensors is that they are low-drift sensors. Additional features of representative pressure sensors include the presence of first and second strain transducers that are associated with a compliant member so that their outputs respond oppositely to deflection of the compliant member resulting from differential pressure across the compliant member but respond similarly to deformation of a substrate on which the compliant member is mounted. The subject pressure sensors find use in a variety of applications.
Abstract: The object of this invention is a process for the creation of at least one recombinant polynucleotide sequence comprising a step of oriented ligation of fragments derived from a bank of at least two polynucleotide sequences, and optionally cloning the recombinant polynucleotide sequences, and the selection of polynucleotide sequences offering advantageous characteristics compared to one or several reference sequences.

Abstract: An elongated composite tube made up of an inner tube 42 and an outer tube 44 (see FIG. 3) with a plurality of elongated helical ribs disposed between the inner tube and the outer tube in a supporting relationship to both. A slinky like toy made from the composite tube is also disclosed, as is a method of making both.
Abstract: Ligation-mediated method of recombining polynucleotides in vitro. Polynucleotides from a library are fragmented and the fragments are hybridized to an assembly template. The hybridized fragments are iteratively re-hybridized and ligated until the ends of the hybridized fragments are adjacent to the ends of other hybridized fragments on the assembly template. A final ligation produces recombined polynucleotides.

Abstract: This invention has as its object a method for detecting catalytic activity of a sample, characterized in that it comprises: the incubation of a substrate (S) with the sample that may have the catalytic activity that it is desired to detect, the addition of a reagent (X) that can react either with a chemical group of unconsumed substrate (S) or with a chemical group of product (P) that is formed after an incubation period with the sample, the addition of a developer (R) that can react with reagent (X), and the detection of the transformation of developer (R).
Abstract: This invention has as its object a process for generating the idiosyncratic catalytic imprint of a sample, characterized in that it comprises the following stages: the sample that is likely to have the catalytic activity is brought into contact with a group of substrates; the signals that are generated after said contact are captured in some way. Advantageously, after the signals are captured, a processing of the latter that consists of assigning to each signal a digital value constituting a component of a graphic display, for example a color display, of the idiosyncratic imprint is carried out.
Abstract: Methods and systems of the present invention provide for measurement of various cardiac parameters. Methods generally involve causing a change in volume and/or pressure in a heart chamber, measuring the change, and calculating at least one cardiac parameter based on the change. Systems typically include at least one actuator, at least one sensor, and a catheter or other device for positioning at least partially in a heart chamber. In some embodiments, the system may also include a controller, such as a computer or other processor, an external actuator, an external sensor, and/or an ECG device. Methods and systems of the invention may be used to more accurately diagnose cardiac conditions in order to make more informed treatment decisions.
Abstract: The invention concerns a method for determining the activity of a substance using a functional test, characterized in that it consists in detecting and/or measuring the variation of a known function corresponding to one or several proteins produced in vitro in the presence and in the absence of said substances or to the substance in the presence or in the absence of one or several proteins produces in vitro.

Abstract: Methods, apparatus and systems for enhancing cardiac pacing generally provide for measuring at least one cardiac characteristic, calculating at least one cardiac performance parameter based on the measured characteristic(s), and adjusting at least one functional parameter of a cardiac pacing device. Devices may include at least one catheter (such as a multiplexed catheter with one or more sensors and/or actuators), at least one implant (such as a sensor implantable in a heart wall), or a combination of both. Various cardiac performance parameters and/or pacing device performance parameters may be weighted, and the parameters and their respective weights may be used to determine one or more adjustments to be made to the pacing device. In some instances, the adjustments are made automatically.
