A catheter system for removal of occlusive material in a body lumen, the system comprising: a catheter body having a lumen, and extending between a distal end and a proximal end, the catheter body having a distal portion, a proximal portion, the distal portion including a filtration section including a filter media configured to permit blood to pass from the lumen of the catheter body and to inhibit occlusive material from passing out of the lumen of the catheter body, the catheter body including an impermeable section between the distal end of the catheter body and the filtration section, the impermeable section being impermeable to fluid; a control handle coupled to the proximal portion of the catheter body; and a cutter assembly including, a drive mechanism extending between the proximal portion and the distal portion of the catheter body, the drive mechanism being operatively connected to the control handle, a cutter configured to cut occlusive material, the cutter extending distally from the distal end of the catheter body and being coupled to the drive mechanism such that the cutter is rotatable with the drive mechanism, and a conveyor extending within the distal portion of the catheter body, the conveyor being coupled to the drive mechanism such that the conveyor is rotatable with the drive mechanism to convey the occlusive material that enters the device through the distal end of the catheter body from the body lumen proximally within the catheter body and through the filtration section such that blood is permitted to pass from the lumen of the catheter body and the occlusive material is inhibited from passing out of the lumen of the catheter body and is conveyed proximally within the lumen of the catheter body. a catheter body having a lumen, and extending between a distal end and a proximal end, the catheter body having a distal portion, a proximal portion, the distal portion including a filtration section including a filter media configured to permit blood to pass from the lumen of the catheter body and to inhibit occlusive material from passing out of the lumen of the catheter body, the catheter body including an impermeable section between the distal end of the catheter body and the filtration section, the impermeable section being impermeable to fluid; a control handle coupled to the proximal portion of the catheter body; and a cutter assembly including, a drive mechanism extending between the proximal portion and the distal portion of the catheter body, the drive mechanism being operatively connected to the control handle, a cutter configured to cut occlusive material, the cutter extending distally from the distal end of the catheter body and being coupled to the drive mechanism such that the cutter is rotatable with the drive mechanism, and a conveyor extending within the distal portion of the catheter body, the conveyor being coupled to the drive mechanism such that the conveyor is rotatable with the drive mechanism to convey the occlusive material that enters the device through the distal end of the catheter body from the body lumen proximally within the catheter body and through the filtration section such that blood is permitted to pass from the lumen of the catheter body and the occlusive material is inhibited from passing out of the lumen of the catheter body and is conveyed proximally within the lumen of the catheter body. a drive mechanism extending between the proximal portion and the distal portion of the catheter body, the drive mechanism being operatively connected to the control handle, a cutter configured to cut occlusive material, the cutter extending distally from the distal end of the catheter body and being coupled to the drive mechanism such that the cutter is rotatable with the drive mechanism, and a conveyor extending within the distal portion of the catheter body, the conveyor being coupled to the drive mechanism such that the conveyor is rotatable with the drive mechanism to convey the occlusive material that enters the device through the distal end of the catheter body from the body lumen proximally within the catheter body and through the filtration section such that blood is permitted to pass from the lumen of the catheter body and the occlusive material is inhibited from passing out of the lumen of the catheter body and is conveyed proximally within the lumen of the catheter body.
