A catheter system for removal of occlusive material in a body lumen. The catheter system includes a catheter body, extending between a distal end and a proximal end and having a proximal portion and a distal portion. The catheter body includes a filtration section having filter media configured to permit blood to pass through the lumen of the catheter body and inhibiting occlusive material from passing out of the catheter body. The catheter system also includes a control handle coupled to the proximal portion of the catheter body and a cutter assembly having a drive mechanism operatively coupled to the control handle. The cutter assembly includes a drive mechanism and a conveyor coupled to the drive mechanism and rotatable with the drive mechanism to convey occlusive material proximally within the catheter body and through the filtration section.

Catheter-based occlusion removal systems and method

Various aspects of the present disclosure are directed toward systems, methods, and apparatuses that include an occlusion device having a barrier member. The barrier member may include an enlargeable portion and a tail portion extending from the enlargeable portion. The enlargeable portion and the tail portion are releasably coupled to the delivery catheter such that the tail portion is radially unsupported and collapsible upon deployment.

Occluder devices

A diametric adjustment mechanism for an implantable medical device including a track defining a series of diametric setpoints, including a first diametric setpoint and a second diametric setpoint, a rider engaged with the track such that the rider is selectively movable along the track from the first diametric setpoint to the second diametric setpoint and from the second diametric setpoint to the first diametric setpoint, and a biasing element biasing the rider toward the first diametric setpoint when the rider is at the second diametric setpoint.
