Abstract: An axial flux motor includes a housing; a drive shaft disposed within the housing; at least one rotor; and at least one stator. The at least one rotor includes a diametrically-magnetized single pole pair magnetic ring having a rotor aperture defined through the center of the magnetic ring, where the drive shaft extends through the rotor aperture and where the at least one rotor is fixed to the drive shaft. The at least one stator includes a number of conductive windings and a stator aperture, where the drive shaft extends through the stator aperture and where the drive shaft is rotatable within the aperture. The at least one stator is configured to generate an axial magnetic field that causes the at least one rotor to rotate, thereby rotating the drive shaft.

Abstract: The present disclosure relates to the field of endoscopy. Specifically, the present disclosure relates to systems and methods for en bloc resection of malignant and pre-malignant lesions and/or tumors within the gastrointestinal (GI) tract. More specifically, the present disclosure relates to systems and methods for delivering an expandable scaffold between tissue layers (e.g., between the muscularis and submucosa layers) to elevate and stabilize the lesion or tumor for fast and efficient resection.

Abstract: A blood pump includes an impeller; a drive shaft coupled to the impeller and configured to rotate with the impeller; and a rotor coupled to the drive shaft and configured to rotate with the drive shaft. The rotor includes a driven magnet having an outer surface. A corrosion-resistant coating may be disposed on the outer surface of the driven magnet. A stator is disposed adjacent the rotor and configured to drive the rotor, causing the rotor to rotate; and a motor is configured to drive the stator. A protection assembly may be disposed adjacent the stator and configured to receive an end of the drive shaft, and may include a protection assembly housing enclosing a protective fluid chamber, the protective fluid chamber including the driven magnet and at least a portion of a bearing configured to engage the end of the drive shaft.

Abstract: Medical devices and methods for making and using medical devices are disclosed. An example medical device may include a medical device for measuring blood pressure. The medical device may include an elongated shaft having a proximal region and a distal region. An optical fiber may extend along the proximal region. An optical pressure sensor may be coupled to the optical fiber. The medical device may also include a tubular member having a proximal end disposed adjacent to the optical pressure sensor and a distal portion extending along the distal region of the shaft.

Abstract: The invention relates generally to a medical device that is useful for delivering a therapeutic agent to the body tissue of a patient, and the method for making such a medical device. More particularly, the invention is directed to a stent having a tubular sidewall with a first coating composition on at least the luminal surface and/or abluminal surface, and a second coating composition disposed on at least a portion of the first coating composition comprising a low diffusivity biodegradable polymer.
