Abstract: An atherectomy system includes an electric drive mechanism that is adapted to rotatably actuate an atherectomy burr and a controller that is adapted to regulate operation of the electric drive mechanism. The controller regulates operation of the electric drive mechanism in accordance with a power input limit value that limits how much power can be put into an atherectomy burr and an energy input limit value that limits how much energy can be put into the atherectomy burr. The controller may also regulate operation of the electric drive mechanism in accordance with a dynamic torque limit.

Abstract: The present disclosure provides apparatus and methods to both infer stent expansion (vessel expansion or compliance) and probability of procedural success (vessel patency) from pretreatment diagnostic imaging at the point-of-care and also train an inference model to generate such an inference, thus allowing a physician to choose with greater certainty an optimal treatment tool and treatment protocol for treating a vessel of a patient.

Abstract: A device includes a first retainer plate, a second retainer plate, a connector link, and a clamp. The second retainer plate has a clearance aperture. The connector link has a first end and a second end. The first retainer plate is coupled to the first end and the second retainer plate is coupled to the second end. The first retainer plate and second retainer plate are in parallel alignment. At least one of the first retainer plate and the second retainer plate are elastically urged to converge. The clamp is coupled to the connector link by a joint. The joint is configured to articulate in at least two degrees of freedom and configured to retain a selected fixed alignment as to the connector link relative to the clamp.

Abstract: A device includes a switch and a housing. The switch is configured for manipulation by a user. The housing has an interior surface configured to receive an external feature of a handheld controller for a transesophageal ultrasound system. The housing has a plurality of switch positions. The switch is coupled to the housing at one position of the plurality of switch positions.
