Abstract: Device and method for rapid extraction of body tissue from an enclosed body cavity. Hollow entry cannula with optional core element provides entry into body tissue space such as bone marrow. Aspiration cannula is inserted through cannula into body tissue and is manipulated to advance directionally through body cavity. Optional stylet within aspiration cannula aids in advancing aspiration cannula through body tissue and is removed to facilitate extraction of body tissue through the aspiration cannula. Inlet openings near distal tip of aspiration cannula allow tissue aspiration, with negative pressure source at proximal end of aspiration cannula providing controlled negative pressure. Aspiration cannula may be withdrawn and its path adjusted for multiple entries through the same entry point, following different paths through tissue space for subsequent aspiration of more tissue.
Abstract: Dental retention systems which facilitate the adjustment or removal of an oral appliance, e.g., a crown or bridge, from a reconfigurable abutment assembly are described. The adjustable abutment assembly may be secured to an anchoring implant bored into the bones within the mouth. The abutment assembly has a projecting abutment portion with one or more shape memory alloy compression plates or elements extending along the projecting abutment portion. Each of the plates has a length with one or more straightened portions and with at least one curved or arcuate portion. Energy may be applied to the elements such that the arcuate portion self-flattens to allow for the oral appliance to be placed thereupon while removal of the energy allows the elements to reconfigure into its curved configuration thereby locking the oral appliance to the abutment. Removal of the oral appliance may be effected by reapplication of energy to the elements.

Abstract: Optical ear infection treatment device and methods are described where an LED and optical light pipe are used to deliver the light from the LED to the middle ear of a patient to reduce bacterial growth and/or eliminate bacteria. Typically, the device is placed in the ear and then activated by the user by pressing an activation button. Once activated the control electronics will turn on the LED and perform a treatment. The most basic treatment mode comprises turning on the LED at maximum power for a predetermined period, e.g. 30 minutes, 60 minutes. When the preset duration is completed, the device will notify the user by an audible beep or vibration that the treatment is complete. Once completed the user can remove the device, the treatment could be repeated once a day or for extreme cases multiple times during the day.

Abstract: The attenuation or isolation of environmental parameters on a gastric lumen is described herein. Once tissue plications are formed into a gastric lumen or sleeve within a stomach, the newly formed lumen is subjected to a multitude of fluctuating stresses or pressure from food or fluids passing therethrough, from naturally-occurring contractions, and/or from changes in pH levels from caustic stomach acids and hormones. The tissue interface between these plications can be isolated from such environmental fluctuations, or the fluctuations can be attenuated, by a number of methods. One example is to place a gastric stent or sleeve within the newly formed lumen. Another example is to utilize multiple rows of anchors, clips, or sutures along the interface. Alternatively, bio-adhesives can be dispensed to buttress the tissue interface. In another variation, the tissue can be approximated in different configurations which effectively reduce or isolate the adhered tissue region.
