Abstract: A current mode buck-boost converter has an input terminal, an output terminal, and an output capacitor coupled to the output terminal. The input terminal is used to receive an input voltage, and the output terminal is for producing the output voltage. The current mode buck-boost converter comprises a voltage converter and a control circuit. The voltage converter comprises an inductor. The control circuit is for detecting the current passing through the inductor to determine the electric energy transmitted to the output terminal by the voltage converter. Accordingly, the current mode buck-boost converter has fast response, and the electrical energy can be recycled and stored to the voltage source when the current mode buck-boost converter operates in down-tracking process.

Abstract: A battery management circuit, a battery module and a battery management method are provided. The battery management circuit includes a conduction circuit and a control circuit. The battery management is coupled to a rechargeable battery cell and has a first conduction path passing through the rechargeable battery cell and a second conduction path without passing through the rechargeable battery cell. The control circuit is coupled to the rechargeable battery cell and the conduction circuit, and conducts selectively the first conduction path or the second conduction path of the conduction circuit so as to avoid over charging or over discharging of the rechargeable battery cell.

Abstract: A method and system for delivering a medicament into tissue, for example via a balloon with small pores. Optionally, the pressure used is high enough to cause jetting, but the pore sizes, pore density, pressure and/or delivery time are such that the jetting do not cause unacceptable tissue damage. Optionally, the pores are smaller than 2 microns, are between 300 and 600 per square centimeter and the pressure is above 8 atmospheres.

Abstract: A system and method for delivering medicament to tissue, using a pulse pressure source and optional pre-pressuring. Optionally, the delivery system is modular and/or adjustable for various applications. Optionally, the treated tissue is a blood vessel wall. Optionally, the delivery system is mechanical.

Abstract: A suturing device for suturing a portion of biological tissue includes a needle attached to a suture, a needle holder that releasably holds the needle, and a needle driver adapted to be advanced and retracted substantially parallel to a longitudinal axis of the suturing device. A distal needle holder adapted to releasably hold the needle is positioned in a distal position relative to the portion of biological tissue and a distal end of the needle driver is positioned in a proximal position relative to the portion of biological tissue. The needle is positioned in either the proximal position or the distal position. The needle driver is moved longitudinally in a first direction along a path substantially parallel to the longitudinal axis such that the needle and suture pass through the portion of biological tissue, thereby forming a suture incision through which the suture passes. By repeating the above-described processes, a series of stitches is thereby formed.

Abstract: A pressure sensitive valve comprising: (a) an outer balloon adapted for intravascular insertion comprising at least one hole adapted for ejection of a fluid; (b) an inner structure adapted to substantially fill the outer balloon; (c) at least one selectively blockable flow path between the outer balloon and the inner structure, at least some of the at least one flow path in fluid communication with at least one of the at least one hole; (d) an inlet port to the at least one flow path; and (e) a pressure source operable to provide a fluid at least at a selected injection pressure to the inlet port. A flow of the fluid along the at least one selectively blockable flow path to the at least one hole is prevented when the pressure source provides any pressure below the selected injection pressure and a flow of the fluid along the at least one selectively blockable low path to the at least one hole occurs when the pressure source provides pressure at or above the selected injection pressure.

Abstract: A balloon for injecting material into a wall of a hollow organ of a human, comprising: an expandable balloon body having a surface and having an axis; at least one predefined ejection port on said body adapted for ejection of fluid therefrom, in a transaxial direction; and an impulse source configured for and adapted to eject material out of said point at a velocity and shape suitable for mechanically penetrating tissue adjacent said port.
