79results about How to "Reduce and eliminate formation" patented technology

A flexible medical closure screen for closing a separation of first and second tissue portions is provided, which includes a mesh screen comprising tubular vertical risers, vertical strands with barbed filaments, and horizontal spacers connecting the risers and strands in a grid-like configuration. An optional perimeter member partly surrounds the screen and can comprise a perimeter tube fluidically coupled with the vertical risers to form a tubing assembly. Various input / output devices can optionally be connected to the perimeter tube ends for irrigating and / or draining the separation according to methodologies of the present invention. Separation closure, irrigation and drainage methodologies are disclosed utilizing various combinations of closure screens, tubing, sutures, fluid transfer elements and gradient force sources. The use of mechanical forces associated with barbed strands for repositionably securing separated tissues together is disclosed. The use of same for eliminating or reducing the formation of subcutaneous voids or pockets, which can potentially form hematoma and seroma effects, is also disclosed. Alternative embodiment flexible closure screens and methods of using same are also disclosed.

An irrigated ablation catheter provides improved distribution of irrigation fluid across its tip electrode surface resulting in improved cooling and flushing of blood and proteins from the tip region. An axially directed flow of irrigation provides improved heat transfer from the tip electrode to the irrigation fluid allowing for a cooler tip electrode and larger lesions. The irrigation fluid is introduced to the catheter with improved flow by means of a standard constant flow pump. A lumen or tube within a shaft of the catheter transfers the irrigation fluid to a proximal end of the tip electrode where it exits the catheter via a flow directing member mounted on the tip electrode. In one embodiment, the flow directing member is a thin walled tube that surrounds the proximal end of the tip electrode and directs the irrigation fluid distally along an outer surface of the tip electrode.

A multilayer dielectric tunnel barrier structure and a method for its formation which may be used in non-volatile magnetic memory elements comprises an ALD deposited first nitride junction layer formed from one or more nitride monolayers i.e., AlN, an ALD deposited intermediate oxide junction layer formed from one or more oxide monolayers i.e., AlxOy, disposed on the first nitride junction layer, and an ALD deposited second nitride junction layer formed from one or more nitride monolayers i.e., AlN, disposed on top of the intermediate oxide junction layer. The multilayer tunnel barrier structure is formed by using atomic layer deposition techniques to provide improved tunneling characteristics while also providing anatomically smooth barrier interfaces.

A method for the continuous production of cookies having a high content of large inclusions, such as chocolate chips, nuts, and fruit pieces includes extruding a cookie dough containing the inclusions through a die orifice to obtain an extrudate dough rope, and cutting the extrudate dough rope with an ultrasonic cutting blade. The ultrasonic cutting severs the extrudate dough rope into dough pieces which fall onto a moving conveyer into a substantially uniform or regular array for uniform baking. The ultrasonic cutter is controlled to provide a roughened top surface on a dough piece to provide a home baked appearance upon baking, while cutting through the inclusions without substantial displacement of the inclusions which would cause pock marks on the surface of the dough piece, and without substantial dough piece weight variation.
