Abstract: An atherectomy system includes a housing and a drive mechanism disposed within the housing, the drive mechanism including a knob that allows translation of the drive mechanism relative to the housing. A sensor is adapted to detect a current position of the knob relative to the housing. A controller is adapted to utilize the signal representative of the current position of the knob to ascertain whether the drive assembly is moving in a direction indicative of anterograde ablation or a direction indicative of retrograde ablation. A stall stop mechanism is adapted to move the drive assembly in a direction opposite a direction of ablation when a stall is determined to be imminent. The controller is further adapted to determine when a stall is imminent, and to actuate the stall stop mechanism in an appropriate direction when a stall is imminent.

The atherectomy burr body has an outer surface defining a distal tapered surface and a proximal tapered surface, where the distal tapered surface has a first abrasiveness adapted for anterograde ablation and the proximal tapered surface has a second abrasiveness adapted for retrograde ablation. In some cases, the first abrasiveness is greater than the second abrasiveness.

Abstract: A catheter system includes a catheter having an elongate shaft, a balloon and a light guide. The balloon expands from a collapsed configuration to a first expanded configuration. The light guide is disposed along the elongate shaft and is in optical communication with a light source and a balloon fluid. A first portion of the light guide extends into a recess defined by the elongate shaft. A protection structure is disposed within the recess and is in contact with the first portion of the light guide. The light source provides pulses of light to the balloon fluid, thereby initiating plasma formation and rapid bubble formation within the balloon, thereby imparting pressure waves upon a vascular lesion. The protection structure can provide structural protection from the pressure waves to the first portion of the light guide.

Abstract: A braking system includes an actuating unit for specifying a braking intention, and multiple braking devices. A first braking device includes a wheel brake, onto which a drivable pressure generator is able to apply a pressure medium, which is under braking pressure, the pressure generator being contactable with a pressure medium reservoir via a supply line. A second braking device, for converting kinetic energy of the motor vehicle into electric energy, is equipped with a drivable electric machine. The two braking devices jointly contribute to the generation of the braking power of the braking system, the respective proportion of a braking device in the braking power being variable. A connection is established, through which pressure medium is able to flow, from the wheel brake to the pressure medium reservoir using an electronic control unit, when the second braking device is able to itself generate the braking power.

Abstract: Methods and systems for generating dynamic voicemail greetings are disclosed. According to an implementation, a voice call made from a caller to a recipient is directed to a voicemail server when the recipient is unreachable. The voicemail server may determine a relationship between the caller and the recipient. The voicemail server may further determine at least one of location data, event data, or time data associated with the recipient. The voicemail server may obtain the real-time location and event data from the recipient's phone and combine it with the saved location and event data to determine the content for the voicemail greeting message. The voicemail server may further select one or more templates based on the relationship between the caller and the recipient and the location and event content and generate a dynamic greeting message to be transmitted to the caller.
