Abstract: Medical devices and methods for making and using medical devices are disclosed. An example medical device may include a guide extension catheter. The guide extension catheter may include an elongate tubular member having a proximal region, a distal region, and a slot formed in the tubular member between the proximal region and the distal region. The proximal region of the tubular member may be configured to shift between a first configuration and a collapsed configuration. The guide extension catheter may also include an elongate shaft for shifting the proximal region between the first configuration and the collapsed configuration.

Abstract: Devices and methods for assisting blood flow are provided. The device includes a housing with an inlet and an outlet, and a fluid barrier separating the housing into a first section containing the inlet and outlet, and a second section. The device also includes an impeller shaft coupled to an impeller and a first magnet in the first section of the housing, and a drive shaft coupled to a second magnet in the second section of the housing. The first and second magnets are arranged such that rotation of the drive shaft rotates the second magnet causing rotation of the first magnet, which drives the impeller.

Abstract: Nanoparticles can be embedded into a medical device by accelerating them to a speed of between 100 m/s and 1,000 m/s and embedding the particles into a polymer surface of a medical device or a precursor thereof. In some cases, the nanoparticles can be embedded until the nanoparticles accumulate in sufficient number to adhere together to form a coating over the polymer surface. The nanoparticles can provide a conductive pathway, an abrasion resistant surface, a pro-healing surface, and/or an anti-bacterial surface.
