A means and method for inserting drivers into a surgical stapling cartridge, including a pallet that holds the cartridge firmly. The pallet has a central slot and laterally positioned lip members that are biased toward the slot. The cartridge is positioned in the slot and the lip members are released to extend their lips over the lateral flanges on the cartridge, thereby holding the cartridge in position. A finger extends into a recess formed at one end of the cartridge, thereby positively positioning the cartridge in the slot. The cartridge is released for removal by a tongue inserted between the lip members, thereby separating them by displacement.

A cutting instrument including a metal blade has a recess formed therein and a semiconductor substrate affixed to the blade in the recess. The semiconductor substrate includes at least one sensor formed thereon. The sensor formed on the semiconductor substrate may comprise at least one or an array of a strain sensors, pressure sensors, nerve sensors, temperature sensors, density sensors, accelerometers, and gyroscopes. The cutting instrument may also further include a handle wherein the blade is affixed to the handle and the semiconductor substrate is electrically coupled to the handle. The handle may then be coupled, either physically or by wireless transmission, to a computer that is adapted to display information to a person using the cutting instrument based on signals generated by one or more of the sensors formed on the semiconductor substrate. The computer or handle may also be adapted to store data based on the signals generated by one or more of the sensors. A method of making said cutting instrument includes the steps of at least one sensor being formed on a semiconductor wafer and a layer of photoresist being applied on a top side of the semiconductor wafer according to a pattern that matches the defined shape of the semiconductor substrate. The portion of the semiconductor wafer not covered by the photoresist is removed and thereafter the photoresist is removed from the semiconductor wafer, thereby leaving the semiconductor substrate having a defined shape and at least one sensor formed thereon. The semiconductor substrate having a defined shape and at least one sensor formed thereon is then affixed to a metal blade in a recess formed in said blade.

Power tool (11) may include a motor and oil pulse unit (22) that generates an elevated torque. Oil pulse unit (22) may be coupled to the motor and have output shaft (18). When load acting on output shaft (18) is less than a predetermined value, rotating torque generated by the motor is directly transmitted to output shaft (18). When the load acting on output shaft (22) exceeds the predetermined value, an elevated torque is generated by oil pulse unit (22) and applied to output shaft (18). Output shaft (18) may be connected to load shaft (12). A socket may be attached to the distal end of load shaft (12). Power tool (11) may further include detecting device (20) for detecting change in rotational angle of output shaft (18) and the direction of rotation thereof, and a control device. The detecting device (20) may output signals corresponding to a state of output shaft (18) to the control device. The control device may store the state of output shaft (18) at predetermined interval. Preferably, the control device may further determine a generating time, at which oil pulse unit (22) generates the elevated torque, based upon the state of output shaft (18).

The present disclosure relates to a cartridge for an aerosol delivery device such as a smoking article. The cartridge may include a base, a reservoir substrate, and an atomizer. The reservoir substrate may define a cavity therethrough. The atomizer may comprise a liquid transport element and a heating element extending at least partially about the liquid transport element. The atomizer may extend through the cavity through the reservoir substrate such that the heating element is positioned proximate an end of the reservoir substrate. Ends of the liquid transport element may extend to an opposing end of the reservoir substrate. A related method for assembling a cartridge for a smoking article is also provided.

Embolic protection filters and methods of making and using such devices are disclosed. An illustrative method of making a device for filtering embolic debris from a body may include the steps of molding a filter assembly that includes a distal tip and a filter portion, forming a plurality of apertures within the filter portion, and coupling a support member to the filter assembly that is adapted to shift the filter portion between a collapsed configuration and an expanded configuration.

The invention relates to a hand tool for use with attachments. The hand tools of the invention may be used with attachments with various speed and torque requirements. Preferred hand tools comprise a body with a brushless DC motor and means. which control the energisation of the motor. In use the brushless DC motor of the preferred hand tool is electrically supplied to drive a power output means connected to said motor. Another preferred hand tool comprises a body with a motor contained therein, a void space between an internal surface of the body and at least a part of the motor, a fluid inlet port provided and a fluid outlet port provided in or on the body, and ducting means which provides a channel for fluid supplied via the fluid inlet port to and from the void space and then on to the fluid outlet port.
