摘要:
An improvement in a stapling device and method designed to capture a tissue fold between first and second members in the device and to staple and cut the fold to form a stapled tissue plication with a hole therein is disclosed. The improvement includes an engagement assembly in the first member movable from a retracted position in the first member to an extended position in the second member, and releasably attached to second member, an anchor assembly that includes the anchor, wherein (i) movement of the engagement assembly from its retracted to its extended position, through a tissue fold captured in the device between the first and second device members, is operable to engage the anchor assembly, and (ii) movement of the engagement assembly, with the anchor assembly engaged therewith, back toward its retracted position, is effective to pull at least a portion of the assembly through the hole in the stapled tissue plication formed by the device.
摘要:
Kits and method for detecting bacterial endotoxin in an aqueous solution are provided. In certain examples, the kit includes at least a first container comprising solid, endotoxin-specific, horseshoe crab amebocyte lysate, whereby the sensitivity of the amebocyte lysate is pre-certified. In certain examples, the kit also contains at least a second container comprising a defined quantity of endotoxin configured as a positive product control, wherein the defined quantity of the endotoxin is pre-certified to react positively with the amebocyte lysate in the first container.

Kits and method for detecting bacterial endotoxin in an aqueous solution are provided. In certain examples, the kit includes at least a first container comprising solid, endotoxin-specific, horseshoe crab amebocyte lysate and at least one buffer, whereby the sensitivity of the amebocyte lysate is pre-certified. In certain examples, the kit also contains at least a second container comprising a defined quantity of endotoxin configured as a positive product control, wherein the defined quantity of the endotoxin is pre-certified to react positively with the amebocyte lysate in the first container.
摘要:
Attach a thermoplastic polymeric foam to multiple spaced apart structural support members of a structure wherein the foam has a resistance to water vapor permeability (mu) that is less than 50, a thermal conductivity that is less than 40 milliwatts per meter*Kelvin, a compressive strength that is greater than 80 kilopascals, and a density of 48 kilograms per cubic meter or less to provide insulation while also providing water vapor-permeability and structural durability to the structure.
摘要:
The present invention relates to a simple, rapid, and cost-effective test kit for specifically detecting bacterial endotoxin in aqueous solutions, such as water or dialysate solutions, using a Limulus Amebocyte Lysate (LAL)-based gel clot assay. Advantageously, the test kit can vary in its level of sensitivity for detecting endotoxin.
