Abstract: Systems and methods include providing a tolerance ring with a friction enhancement feature on at least one surface of the tolerance ring to increase at least one friction-related property of the tolerance ring. The friction enhancement feature provides the tolerance ring with an increased retention force while providing an optimum radial force that allows a component secured by the tolerance ring to move freely while reducing or altogether preventing axial movement of the component.

Abstract: Systems and methods include providing a tolerance ring in an electric drive motor assembly having a housing and a stator disposed within the housing. The tolerance ring is disposed within the housing and retains or secures the stator within the housing and control movement of the stator within the housing. The tolerance ring includes an annular ring-shaped substrate formed from a metallic material and a plurality of projections protruding radially inward from an inner surface of the substrate or radially outward from an outer surface of the substrate. The tolerance ring optionally includes one or more cooling features formed in the substrate and configured to promote cooling between a fluid disposed in the housing and the stator.

Abstract: A tolerance ring (200) including a tolerance ring sidewall (404) including a plurality of waves (or bridges) (452) extending at least one of radially inward or outward and having first (416) and second end portions (420) terminating at first (417) and second ends (421), respectively, where the tolerance ring has a first radius of curvature Ri, measured at a point bisecting a circumferential length, LC, of the tolerance ring sidewall, and a second radius of curvature, R2, measured along one of the first and second end portions of the tolerance ring sidewall, and wherein at least one of: 1) Ri is greater than R2, or 2) wherein Ri is negative and R2 is positive.

Abstract: Devices, systems and methods for removal of a mitral valve clip and subsequent delivery of a mitral valve implantation in a mitral valve replacement procedure. A modular port accessory device having a distal connector configured to be compatible with corresponding connectors on an existing therapeutic device, wherein the port accessory can be selectively attached to a proximal end portion connector of a proximal end portion of a catheter assembly of an existing therapeutic device. The catheter assembly is introduced to a target site within the patient's anatomy, and remains in place throughout a multistep therapeutic procedure for use with other therapeutic devices, all while allowing hemostasis to be controlled during use ad interchange of multiple therapeutic devices.

Abstract: A device configured to cut leaflet tissue at a cardiac valve may comprise a guide catheter having a proximal end and a distal end, the guide catheter being positionable at a cardiac valve. The device may further include a cutting mechanism routable through the guide catheter and configured to extend from the distal end of the guide catheter, the cutting mechanism configured to cut a portion of leaflet tissue of the cardiac valve. Finally, the device may comprise a handle coupled to the proximal end of the guide catheter, the handle comprising at least one control operatively connected to the cutting mechanism such that the at least one control is configured to provide selective actuation of the cutting mechanism.

Abstract: A system for cutting leaflet tissue at a cardiac valve may comprise a guide catheter having a proximal end and a distal end, wherein the distal end of the guide catheter is steerable to a position above a cardiac valve. The system may also include a handle coupled to the proximal end of the guide catheter, the handle comprising at least one control configured to steer the guide catheter to the position above the cardiac valve. Finally, the system may comprise a cutting mechanism routable through the guide catheter and able to be positioned at the distal end of the guide catheter, the cutting mechanism configured to cut a portion of leaflet tissue of the cardiac valve.

Abstract: A system configured to cut leaflet tissue at a cardiac valve may comprise a guide catheter having a proximal end and a distal end, wherein the distal end of the guide catheter is steerable to a position above a cardiac valve. The system may also include a hook catheter having a proximal end and a distal end, the hook catheter configured to extend from the distal end of the guide catheter through a first orifice of the cardiac valve. Further, the system may comprise a cutting mechanism extending from the hook catheter, the cutting mechanism configured to cut a portion of leaflet tissue of the cardiac valve. Finally, the system may include a handle coupled to the proximal end of the guide catheter, the handle comprising at least one control operatively connected to the cutting mechanism.

Abstract: A system configured to detach an interventional implant from a cardiac valve includes a guide catheter and a capture mechanism routable through the guide catheter. The capture mechanism comprises a capture hypotube with a container portion/space configured to receive an interventional implant connected to cardiac valve tissue. The capture mechanism also includes a cutting arm axially moveable relative to the capture hypotube. The capture hypotube and the cutting arm each include cutting elements that are brought together upon actuation of the cutting arm to thereby cut the cardiac valve tissue surrounding the interventional implant to free the implant from the cardiac valve.

Abstract: An electric motor or generator assembly includes a stator, a housing, and an annular member fit between the stator and the housing, where the annular member is radially compressed so as to exert a radial force outward onto the housing and inward onto the stator to maintain a positional relationship therebetween.

Abstract: A vehicle ballast system for improving the balance of a vehicle. The system is particularly well suited for use in the bed of a pickup truck but is not limited to that deployment. The system includes one or more ballast units. Each ballast unit includes a frame set and a ballast element. The frame set retains the ballast element therein. The ballast element may be one or more concrete blocks. The frame set includes an upper frame and a lower frame. The respective frames are connected together in a manner to contain the ballast element using a front retaining rod and a rear retaining rod is preferably affixable to a bracket secured to the rear of the vehicle. A tether may be removably connected between the upper frame and a securing point of the vehicle. A shock-absorbing lanyard may be employed at the rear of the system as a restraint upon sudden deceleration of the vehicle.
