Abstract: An atherectomy system includes a handle having a handle housing, with a drive member extending through the handle housing and operably coupled to an atherectomy burr. A drive mechanism is disposed within the handle housing and is adapted to rotatably engage the drive member. The drive mechanism may include an electric drive motor, a drive gear that is rotatably engaged with the electric drive motor and a driven gear that is coupled with the drive member and is engaged with the drive gear such that rotation of the driven gear causes rotation of the drive member. The drive mechanism may be configured to enable a rotation speed of the atherectomy burr of up to at least about 200,000 revolutions per minute (rpm).

Abstract: Example medical devices are disclosed. An example medical device includes a handle having a distal end region, a proximal end region and an inner chamber. The medical device also includes a guidewire brake including an actuation member coupled to a first gripping member and a second gripping member. The first gripping member and a second gripping member are disposed within the inner chamber of the handle and at least a portion of the actuation member is positioned along an outer surface of the handle. Further, the first gripping member and the second gripping member are configured to shift between an unclamped configuration and a clamped configuration.

Abstract: A device and method for growing aerobic and facultatively anaerobic bacteria such as Pseudomonas Fluorescens, Bacillus subtilis, Bacillus licheniformis, Starkeya novella and various autotrophic sulfur metabolizing bacteria, along with methods for releasing these bacteria into suspended growth or fixed film wastewater treatment zones such as soil or media, for the purposes of bioremediation and the removal of nitrogen, sulfur, and carbon wastes.
