Removable stent for body lumens

A removable stent for implantation into a lumen in a human body. The stent is made from a soft, flexible fiber having an outer surface. An outer bioabsorbable / degradable coating is applied to the outer surface of the filament causing it to become rigid. The coating softens in vivo through absorption and / or degradation such that the stent is readily passed or removed from the lumen as a softened filament after a pre-determined period of time through normal flow of body fluids passing through the lumen or by manual removal.

An improved system and method for deploying medical electrical leads is disclosed. The system includes a guiding device such as a guidewire used to navigate the vascular system of a body. The guiding device includes a fixation member that can be deployed to maintain the guiding device at a desired location within the vascular system. The fixation member may be an inflatable device such as a balloon, or alternatively, may be an expandable device constructed of flexible fibers that has both an expanded and a contracted state. The system may further include a coupling member located adjacent to the guiding device. The coupling member may be a rail extending distally from a proximal end of the guiding device to a point proximal the fixation member. In an alternative embodiment of the invention, the coupling member is a channel included in the body of the guiding device adapted to slidably engage an electrode assembly. The coupling member is adapted to allow the electrode assembly to be slid to the distal end of the coupling member and deployed at a predetermined implant site. In one embodiment of the invention, the coupling member is movable with respect to the guiding device. This allows the coupling member to be re-positioned to multiple implant sites to deploy more than one electrode while the fixation mechanism remains stationary within a patient's vascular system.

Engineered fibers for well treatments

Mixtures of fibers and solid particles are effective for curing fluid losses and lost circulation in a subterranean well. Stiff fibers are more effective than flexible ones; however, mixtures of stiff and flexible fibers have a synergistic effect. The quantity and particle-size distribution of the solids are optimized according to the stiffness, dimensions and concentrations of fibers.

Debris capture and removal for laser micromachining

A method of capturing and removing metallic debris created on a target side of a target metal specimen undergoing laser micromachining entails providing a barrier that encompasses the immediate volume surrounding a laser cutting head output nozzle to contain the ejected debris and extracting the debris through a vacuum outlet. A preferred system implementing this approach to debris management includes a barrier in the form of a flexible fiber brush configured in the shape of a ring and positioned to trap ejected debris within a localized area surrounding a target area where the laser beam is incident on the target metal specimen. The ring brush is made of material that is robust to molten metals. An inert gas directed at a high flow rate along the target surface of the metal specimen carries ejected surface debris trapped in the ring brush toward a vacuum outlet.
