Abstract: Rotating dental systems and related guards and methods are disclosed. In some instances a guard may be configured to prevent material from building up on at least a portion of the dental system. The guard may be configured to prevent materials from being discharged from the dental system. In some embodiments, the guard may also be configured to direct the flow of material along a portion of the dental system. Some guards within the scope of this disclosure comprise bristles.

Abstract: An improved method and device are provided for forming and/or maintaining a percutaneous access pathway. The device generally comprises at least one of three type of components: access pathway, insertion device, and attachment device. In one embodiment, the device is used to form and/or maintain a percutaneous access pathway into the pleural cavity (i.e. tube thoracostomy). The provided assembly substantially reduces the possibility of iatrogenic infection while accessing and/or re-accessing a body space.

Abstract: The present invention is directed to a manually actuated aspiration device, aspiration system and a method of use to enable and facilitate en bloc removal of undesirable intravascular material, including, but not limited to, thrombus, embolus, or vegetation through a working lumen of a suction cannula during minimally invasive percutaneous procedures. The aspiration device includes valves oriented in opposite direction to control the fluid flow through the aspiration system and into a waste collection component. Alternatively, the aspiration system further comprises a filter that removes undesirable intravascular material prior to reinfusing blood into a patient's vasculature.
