A fixation device for retaining a leadless medical implant to tissue includes an array of elongate tines having self-expanding distal portions. The fixation tines may be advanced between an implant body and an outer jacket to deploy the tines from a delivery configuration in which the tines are constrained by the outer jacket to an expanded configuration in which the distal end portions of the tines are released from the outer jacket. The implant and fixation device are contained within a sheath for delivery to the treatment site and a pusher within the sheath advances the fixation device relative to the implant body and deploys the tines. A distal end of the implant having an electrode may form a distal tip of the delivery system, and a potential implantation site may be tested prior to deployment of the fixation device to allow for easy repositioning of the implant.

A device for percutaneously repairing a heart valve of a patient including a self-expanding, stented prosthetic heart valve and a delivery system. The delivery system includes delivery sheath slidably receiving an inner shaft forming a coupling structure. A capsule of the delivery sheath includes a distal segment and a proximal segment. An outer diameter of the distal segment is greater than that of the proximal segment. An area moment of inertia of the distal segment can be greater than an area moment of inertia of the proximal segment. Regardless, an axial length of the distal segment is less than the axial length of the prosthesis. In a loaded state, the prosthesis engages the coupling structure and is compressively retained within the capsule. The capsule is unlikely to kink when traversing the patient's vasculature, such as when tracking around the aortic arch, promoting recapturing of the prosthesis.

A catheter inner member includes an inner member body, including a first side and a second side, the second side opposing the first side. The inner member body includes an inner surface defining an inner member inner lumen and an outer surface defining a surrounding environment. The inner member further includes at least a first flush port and a second flush port in the inner member body. The first flush port and second flush port provide fluid communication between the inner lumen and a surrounding environment. The first flush port disposed on the first side and the second flush port disposed on the second side, wherein the first flush port is axially displaced from the second flush port.

A packaging system is disclosed for shipping a prosthetic tissue valve in a storage solution and preparing and loading of the bioprosthetic valve onto a catheter-based delivery system. The packaging system includes a fluid tight container filled with the storage solution attached to a delivery catheter, wherein the container surrounds the prosthetic tissue valve that is in a pre-loaded position on the delivery catheter during shipment and storage. The prosthetic tissue valve may include an attachment mechanism that attaches to the delivery catheter to properly position the tissue valve for loading within the delivery catheter. In another embodiment where the prosthetic tissue valve is not attached to the delivery catheter during shipment, the attachment mechanism may interact with the prosthetic tissue valve shipping container to prevent the bioprosthetic valve from moving during shipment.

A delivery system for use with a prosthetic heart valve having a stent frame to which a valve structure is attached includes a shaft assembly including a distal portion and an intermediate portion, and an inner lumen extending through the shaft assembly. The delivery system includes a sheath assembly defining an outer lumen sized to slidably receive the shaft assembly. At least one flush port is formed in the intermediate portion. The at least one flush port is in fluid communication with the inner lumen and the outer lumen. The delivery system is configured to transition from a loaded state in which the sheath assembly encompasses the prosthetic heart valve to a deployed state in which the sheath assembly is withdrawn from the prosthetic heart valve.

A device for percutaneously deploying a stented prosthetic heart valve includes a distal portion, a spacing collar, and an outer collar. The distal portion provides a coupling structure configured to selectively engage the stented prosthetic heart valve. The spacing collar is located proximal to the distal portion. The spacing collar is transitionable from a loaded state to an activated state. The spacing collar in the loaded state has a radial dimension less than the spacing collar in the activated state. The outer collar is configured to be movable relative to the distal portion and the spacing collar. The outer collar is slidably disposed over the spacing collar to provide the loaded state and is slidably retracted from the spacing collar when in the activated state.

In one example, this disclosure is directed to a kit for intravascular implantation of an implantable medical device within a patient, the kit comprising an elongated inner sheath with a distal end, a first coupling module slidably connected to the inner sheath, an elongated outer sheath forming an inner lumen with a distal opening and a proximal opening. The outer sheath sized to traverse a vasculature of the patient. The proximal opening is configured to receive the distal end of the inner sheath. The inner lumen is sized to receive the inner sheath and to contain the implantable medical device. The kit further includes a mating coupling module that connects to the first coupling module such that the inner sheath is axially aligned with the outer sheath. The inner sheath is slidable within the outer sheath while the first coupling module is connected to the mating coupling module.
