Abstract: A surgical saw includes a body, a coupling assembly, and a motor. The coupling assembly is mounted to the body and adapted to releasably hold a saw blade. The coupling assembly includes an anvil, a press, and a clamping assembly. The anvil has a channel or a press foot. The press has the other of the press foot and the channel. The press foot is receivable by the channel. The clamping assembly selectively moves the press and the anvil towards and away from each other. When the press is brought towards the anvil, the press foot may press a lock tooth of the saw blade into the channel so that the lock tooth is compressed between the anvil and the press to coin the lock tooth. The motor, internal to the body, is connected to the coupling assembly to reciprocate the coupling assembly and the saw blade.

Abstract: A control module for a powered surgical tool. The module includes a shell. Internal to the shell is a circuit for controlling the power generating unit of the tool with which the module is associated. Conductive pins extend through the shell to provide electrical connections to the components within the shell. Active seals are disposed around the conductors and the inner walls of the shell that define the openings in which the pins are seated. Each active seal include an inner and outer skirt. A biasing component disposed between the skirts urges the inner skirt against the section of the conductive pin seated in the opening. The biasing component also urges the outer skirt against the adjacent opening-defining inner wall of the shell. The active seal functions as a barrier between the conductive pin and the adjacent inner wall of the shell.

Abstract: A surgical saw and complementary blade. The blade has lock teeth that are more ductal than the cutting teeth. The saw coupling assembly has an anvil and a press. The saw coupling assembly holds the blade to the saw by compressing the saw lock teeth between the anvil and the press so as to result the coining of the lock teeth.

Abstract: A battery and control module to which a powered surgical tool is releasably attached. Internal to the module there is: a cell for energizing the tool; a sensor for monitoring an operational state of the tool; a sensor for monitoring a trigger external to the module; and a control circuit. Based on the signals output by the sensors, the control circuit selectively applies energization signals from the cell to the power generating unit internal to the surgical tool. In some versions of the invention, the trigger is attached to the module.

Abstract: A food intake restriction device for forming a restriction in a patient's gastro-intestinal tract and non-invasively communicating pressure data regarding the restriction to an external monitor. The device includes a food intake restriction device implanted substantially about a patient's gastro-intestinal tract to form a restricted opening in the tract. A port is connected to the restriction device. The port contains a working fluid for affecting the size of the restricted opening. A pressure sensing system communicates with the working fluid to measure the pressure of the working fluid. A transmitter communicates the measured fluid pressure to the external monitor.

Abstract: An external pressure sensing system may include an attachment for a syringe. The attachment may comprise a connector positioned between the barrel and the needle of the syringe. A pressure sensor may be in fluid communication with the connector, such that the pressure sensor may sense the pressure of fluid within the connector as the syringe is used to add fluid to or withdraw fluid from an injection port. Where an injection port is a component of an adjustable fluid-based gastric band system, pressure data obtained with the pressure sensor may be indicative of the pressure of fluid within the gastric band. The pressure sensor may communicate pressure data to a display device. A user may adjust the pressure of fluid within the gastric band using the syringe while viewing the display device for pressure-related readings.

Abstract: An implantable restriction device is configured to provide a restriction in a patient as a function of the pressure of fluid. The implantable restriction device includes one or more pressure sensors configured to sense pressure of the fluid within the implantable restriction device. Pressure data obtained by the one or more pressure sensors may be communicated to a device located external to the patient, such as a data logger, using telemetry coils or other communicators. The data logger may store the pressure data, and may communicate the pressure data to a remote location via a network such as the Internet. A docking station may be provided to couple the data logger to a network and/or to recharge a cell in the data logger.
