Abstract: An embodiment includes a method of data collection optimization in a managed network having a digital experience platform that includes collecting data from managed endpoints using first collection criteria. The first collection criteria include a first frequency and a first verbosity. The method includes identifying, in the collected data, device context data that indicates a defined event exists relative to an endpoint. The collected data or the device context data are used to compute a digital experience index. Responsive to the identified device context data, the method includes modifying the first frequency or the first verbosity to implement a second collection criteria relative to a subset of managed endpoints; collecting additional data from the subset of managed endpoints using the second collection criteria; receiving additional context data that indicates the defined event no longer exists; and in response, collecting data from the managed endpoints using the first collection criteria.

Abstract: A replacement heart valve system may include a replacement heart valve implant including an expandable framework and a plurality of valve leaflets disposed within the expandable framework, and a filter element secured to the expandable framework and configured to be deployed downstream of the expandable framework, the filter element having a closed downstream end. A replacement heart valve system may include a filter element configured to be deployed across a native heart valve, wherein the filter element includes a lumen extending therethrough, and a replacement heart valve implant configured to be deployed within the lumen of the filter element. A method of treating a native heart valve may include deploying a filter element across the native heart valve, expanding an expandable balloon within the lumen of the filter element, and thereafter, deploying a replacement heart valve implant within the lumen of the filter element.

Abstract: An elongate shaft of a medical catheter including a thermoset polymeric tubular member including a skived distal portion. The skived distal portion includes a distally extending trough having a convex surface and a concave surface. A thermoplastic tubular sleeve may be positioned over at least a portion of the skived distal portion of the thermoset polymeric tubular member. In some instances, the thermoplastic tubular sleeve includes a crescent-shaped tubular portion defining a crescent-shaped lumen. The trough of the skived distal portion may extend through the crescent-shaped lumen. The thermoplastic tubular sleeve is thermally bonded to the inner and outer tubular members of a distal section of the elongate shaft at a guidewire port joint.

Abstract: Various embodiments concern a lead having a proximal section and a curbed section. The lead can comprise an outer tubular portion having a bias such that the lead assumes a curved shape along the curved section. The lead can further include an inner tubular portion extending within the outer tubular portion, the inner tubular portion comprising an inner coil conductor and an inner polymer jacket over the inner coil conductor along the curved section, the inner tubular member stiffer along the proximal section than the curved section, the outer tubular portion stiffer along the curved section relative to the inner tubular portion along the curved section such that the inner tubular portion can rotate relative to the outer tubular portion while the curved shape is substantially maintained. Relative rotation can extend and rotate and active fixation element.

The coil assembly may include a coil, a coating disposed on the coil, and a sheath disposed over the coil and the coating. A guidewire lumen may be defined by the coil assembly. An outer tube disposed over at least a portion of the coil assembly. A balloon may be coupled to the outer tube. An inflation lumen may be defined between the coil assembly and the outer tube.

Abstract: Medical devices and methods for making and using medical devices are disclosed. An example medical may include a guide catheter. The guide catheter may include an elongate catheter shaft having a proximal end, a distal end, and a central lumen extending therebetween. An inflatable locking member may be disposed within the lumen. The locking member may be configured to longitudinally secure the position of a medical device extending through the lumen relative to the catheter shaft. The guide catheter may also include an inflation lumen in fluid communication with the inflatable locking member.

Abstract: A catheter assembly may comprise a guide catheter, a balloon catheter with a steering balloon and a stabilizing balloon and a guide wire. The stabilizing balloon secures the balloon catheter to the guide catheter while the steering balloon secures the catheter assembly to the vessel wall. In another embodiment, the balloon catheter has three balloons engaged to the exterior surface, a steering balloon, a stabilizing balloon and an anchoring balloon.

Abstract: A balloon catheter stent deployment system is disclosed wherein a balloon catheter is provided and a tubular stent is crimped onto a distal portion of the balloon with a distal end of the stent in close proximity to a point where the distal end of the balloon is attached to the inner tube of the catheter. A proximal section of the balloon extending from a proximal end of the stent to a point where the proximal end of the balloon is attached to the outer shaft of the catheter remains uncovered by the stent and, has a larger uninflated outer diameter than the crimped stent. Thus, in some embodiments, the proximal section of the balloon provides a protective cone for the proximal end of the stent to help resist frictional forces from disengaging the stent from the balloon in the event the balloon catheter and stent are withdrawn back into a guide catheter during a procedure.
