According to an aspect of the present disclosure, a surgical suture needle assembly is provided including an elongate tube defining a lumen through at least a portion of a length thereof; and a wound treatment material contained within the lumen of the suture structure. The present disclosure further provides for methods of using the surgical suture needle assembly in anastomotic procedures and the like.

Adhesive suture structure and methods of using the same

A microwave processing system is disclosed. The system is particularly useful for concurrently controlling a plurality of chemical reactions from a single microwave source. The system comprises a source (15) that produces electromagnetic radiation in the microwave range; a waveguide (16) in communication with the source and into which the source propagates microwave radiation; a resonator (20) in communication with the waveguide; and adjustable dynamic moderating means (22, 33-36) between the waveguide and the resonator for moderating the wave energy passing from the waveguide to the resonator without substantially changing the propagated mode in the waveguide.

Microwave apparatus for controlling power levels in individual multiple cells

A device for carrying out large-scale chemical reactions includes a microwave generator, a microwave application vessel containing a high-capacity reactor, and a cover, in which the vessel is a cylinder having longitudinal axis X, a microwave inlet in the vessel bottom wall, and an open upper end, in which the generator provides single-mode microwaves along axis X in the vessel, the size of the vessel being made to match the wavelength of the resonant mode of the microwaves along axis X, and in which the cover seals the upper opening of the vessel, and the cover has a conduit that connects the inside of the vessel to the environment so that the vessel is under atmospheric pressure.

Device using microwaves to carry out chemical reactions on a large quantity of product

There is described a sample holder for decomposition or extraction of a sample material, the sample holder comprising: a frame adapted to receive at least two open-ended sample recipients having sealing caps thereon for holding the sample material; and a rack cover releasably securable to the frame and comprising at least two compression caps to be positioned on the sealing caps in order to exert a pressure thereon, thereby forming a pressure-relief valve for each one of the at least two open-ended sample recipients

Multi-sample holder for decomposition or extraction

A method for microwave assisted chemical processes is disclosed that comprises applying sufficient microwave radiation (26) to a temperature-monitored mixture of reagents (22, 23), with at least one of the reagents (22, 23) being thermally responsive to electromagnetic radiation (26) in the microwave range, and based on the monitored temperature (21), to maintain the added reagents at or closely about a predetermined temperature while substantially avoiding thermal dilution (or before substantial thermal dilution can occur) that otherwise would have been caused by the addition of the reagents to one another.

Microwave assisted chemical processes

The invention relates to a method for measuring the temperature of a sample placed in a container of an apparatus for applying microwaves, according to which the measurement is carried out directly by means of a radiation pyrometer. The apparatus (1) implementing the method comprises means (3) for emitting microwaves in an application cavity (4) delimited by a wall (11, 12, 13), at least one container (2) in the application cavity (4), a radiation pyrometer (20) receiving the radiation (21) emitted by the sample (10) directly through an orifice (22) in the wall (11, 12, 13) of the application cavity (4). The apparatus (1) is in particular used for carrying out chemical reactions in a wet medium.

Method for measuring the temperature of an object located in a container of an apperatus for applying microwaves and apparatus for working out this method

A sample is heated by microwaves, and the temperature of the sample is measured by a radiation pyrometer arranged to receive radiation directly from the sample. The sample is disposed in a chamber having an orifice dimensioned to block the passage of microwaves, and admit the passage of radiation. The chamber has an upper wall in which one or more openings are formed for receiving a sample-containing receptacle.
