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: 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.

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: 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: 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 wing cover panel for an aircraft wing is formed as a plurality of sections each carrying stringer sections which are then fixed together to form a wing cover panel with an integral hollow stringer.

Abstract: The present invention relates to a stringer for an aircraft wing and a method of forming such a stringer in which the stringer is formed from a single piece of material and then machined to optimise the dimensions and weight of the stringer.

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.
