A catheter can restore the patency of a body lumen, for example, by removing tissue from a body lumen (e.g., a blood vessel). The catheter can be a rotational catheter having a rotatable drive shaft and a tissue-removing element secured to the drive shaft to be driven in rotation by the drive shaft. The catheter can have an abrasive burr configured to abrade tissue in a body lumen. The catheter can have an expandable tissue-removing element. The catheter can include a balloon and an inflation conduit. The catheter can also be configured to move over a guidewire through a body lumen. In one embodiment, the catheter comprises an over-the-wire, balloon-expandable, rotational, and abrasive tissue-removing catheter.

Catheter

A balloon for a balloon catheter includes a body section and cone sections. At least one of the cone sections defines a plurality of grooves spaced around the circumference of the cone section.

Medical balloon including pleats

A material-removing machine for removing material from a cone section of a medical balloon includes a material-removing element operatively connected to a prime mover such that operation of the prime mover imparts rotation to the material-removing element about a rotational axis. The material-removing element includes an interior surface defining a generally conical-shaped cavity extending along the rotational axis and adapted to receive at least a longitudinal portion of a cone section of an expanded medical balloon for removing material from the longitudinal portion of the cone section to reduce a wall thickness of the cone section. Material may be removed continuously around a 360-degree exterior perimeter of the longitudinal portion of the cone section of the medical balloon to reduce the thickness of the balloon wall defining the cone section.

Material removal from balloon cone

A pump for inducing flow within a vascular system comprises a cannula having a first configuration for deployment within the vascular system and a second configuration for directing the fluid flow within the vascular system, where the second configuration has a greater diameter than the first configuration. An impeller is configured to induce the fluid flow by rotation about an axis. The impeller has a first radius in the first configuration and a second radius in the second configuration, where the second radius is greater than the first radius.
