摘要:
A method for analyzing a gas sample includes the steps of providing a gas sample to a sample canister and heating a sensor to a predetermined resistance. The method further includes the steps of operating a fan at a predetermined speed, and moving a valve to a measurement flow position. When the valve is in the measurement flow position, the fan draws a portion of the gas sample through the valve to expose the sensor to the gas sample.

A device for capturing a breath sample has a mouthpiece with a chamber that receives a breath sample through a breath inlet aperture. The device further includes a pump assembly with a pump that draws a portion of the breath sample from the chamber and discharges the portion of the breath sample to the sensor.

A sensor module includes a substrate with a slot formed therein. A sensor is mounted to the substrate and spans the slot. A first cover is disposed on a first side of the substrate and covers at least a portion of the slot. The first cover comprises a first aperture and a second aperture in fluid communication with the slot. The sensor is disposed between the first and second apertures.

Systems and methods for transeptal cardiac procedures are disclosed. A patient treatment device in accordance with a particular embodiment includes an elongated first intravenous guidewire that includes a first branch and a second branch fixably secured relative to the first branch at a first location. The device can further include an elongated second intravenous guidewire that is movable relative to at least one of the first and second branches between a first position in which the first and second branches are releasably secured relative to each other by the second guidewire at a second location, and a second position in which the first and second branches are separated from each other at the second location.
摘要:
A gas analysis device includes a canister with a cavity that is configured to receive a gas sample. A sensor is in fluid communication with the cavity and analyzes a portion of the gas sample that is received from the canister. The device also includes a blower assembly in fluid communication with the sensor. The blower assembly is configured to selectively draw a portion of the gas sample from the canister past the sensor so that the sensor is exposed to the portion of the gas sample.

Systems and methods for transeptal cardiac procedures are disclosed. A patient treatment system in accordance with a particular embodiment includes a catheter, a tissue penetration device carried by and deployable from the catheter, an energy delivery device carried by an deployable from the catheter, a backstop surface carried by the catheter, and a flexible, resilient tissue compression device. The tissue compression device can be coupled between the energy delivery device and the catheter and can be changeable between a first configuration in which the energy delivery device applies a first force to the backstop surface via intervening tissue, and a second configuration in which the energy delivery device applies no force or a second force less than the first force into the backstop surface via intervening tissue.

The damaged portion of an injured tendon or ligament (C) ("connective cord") is inserted into a thin, hollow sleeve (100, 110, 120, 130, 140, 160, 180, 200, 240, 260, 270, 300, 390, generically designated "S") and is connected to the sleeve (S) such that the cord-sleeve combination can immediately withstand normal tensile forces. The interconnection can be mechanical, such as by pins (22, 22',148, 150, 164, 188, 190, 206, 206', 210, 226, 230, 238, 239, 266, 286, 308) extending through the sleeve (S) and cord (C). The sleeve (S) can be bioabsorbable over a sufficiently long period of time that the cord (C) is healed by the time the sleeve (S) is absorbed.
摘要:
An apparatus (10) for spiral binding a stack of papers (24) together as a unit. The apparatus includes a punch (12) for punching a plurality of holes (23) along one edge of the stack of papers and a spiral binding unit (14) for feeding a spiral coil (36) into the holes. The spiral binding unit (14) includes an aperture (44) through which a coil is inserted between a shoe (74) and a rotatably mounted roller (72). As the coil (36) is inserted, the shoe (74) pushes the coil into contact with the roller (72). As the roller (72) rotates, the coil (36) is guided through a series of slots (86) which cause the coil to spiral into the holes in the stack of paper. The punch (12) includes a ramp (186) that presses a series of punch pins (188) through the stack of papers. The ramp (186) includes a plurality of steps (222) that incline upwardly on either side of a center step (224). The punch first punches holes in the center of the stack of papers and then punches holes outward from either side of the center. The apparatus includes indicators (38) that provide an operator an indication of the appropriate size of spiral coil to use, and an indication of when a wastebasket (52) holding the wastepaper requires emptying.
