Abstract: Loading tools for use with medical devices are disclosed. An example loading tool may include a tubular sleeve having a proximal end region, a distal end region, and a lumen. The distal end region may be designed to be engaged with a resilient seal member of a hemostasis valve so that a medical device disposed within the lumen can be passed through the resilient seal member. The tubular sleeve may include a tube wall. At least a portion of the tube wall may overlap to define an overlapping region.

Abstract: Loading tools for use with medical devices are disclosed. An example loading tool may be suitable for use with a drug-coated expandable medical device. The loading tool may include a tubular sleeve having a distal end region, a proximal end region, and a lumen extending therethrough. The distal end region may include a reduced distal tip designed to interact with a hemostasis valve having a resilient seal member.

Abstract: Medical devices and methods for making and using medical devices are disclosed. An example method may include a method for calculating fractional flow reserve including providing a pressure sensing guidewire, advancing the pressure sensing guidewire through a blood vessel to a first position distal of an intravascular occlusion, determining a distal pressure within the body lumen with the pressure sensing guidewire, proximally shifting the pressure sensing guidewire to a second position proximal of the occlusion, determining a proximal pressure within the body lumen with the pressure sensing guidewire, measuring an aortic pressure, and calculating a pressure drift. The pressure drift may be the difference between the aortic pressure and the proximal pressure. The method may also include calculating a drift-compensated fractional flow reserve. The drift-compensated fraction flow reserve may correspond to (the distal pressure+the pressure drift) divided by the aortic pressure.

Abstract: Medical devices and methods for making and using medical devices are disclosed. An example medical device includes a pressure sensing guidewire. The pressure sensing guidewire may include a tubular member having a proximal portion and a distal portion. The distal portion may have a plurality of slots formed therein. The distal portion may have a first wall thickness along a first region and a second wall thickness different from the first wall thickness along a second region. A pressure sensor may be disposed within the distal portion of the tubular member.
