An implant comprising a shell, a core within the shell, and a conductive layer between the core and the shell; wherein the implant additionally comprises a sensor for detecting a change in one or more electrical properties of the conductive layer. A kit for use in detection of rupture an implant comprising the implant, a method of detecting rupture and a method of manufacture of an implant.

A device implanted within the heart and great vessels, such as a valve clip, includes inbuilt features that can allow its removal, partial or complete, at a later date. The inbuilt features include one or more conductors configured to conduct energy. The energy is used to separate the clip or part of the clip from the surrounding tissue. A system or kit to facilitate this removal includes an inner catheter having a distal end configured to engage and couple with the clip, and a conductor configured to conduct energy between a source of energy and the distal end of the inner catheter. A method to facilitate this removal involves transferring the energy to the clip to cause detachment and separation of at least part of the clip from the surrounding tissue and withdrawing at least part of the clip into an outer catheter.

A medical device configured to perform an endovascular therapy can include an elongate manipulation member and an intervention member. The elongate manipulation member can include a distal end portion. The intervention member can include a proximal end portion and a mesh. The proximal end portion can be coupled with the distal end portion of the elongate manipulation member. The mesh can have a plurality of cells in a tubular configuration and being compressible to a collapsed configuration for delivery to an endovascular treatment site through a catheter and being self-expandable from the collapsed configuration to an expanded configuration. The mesh can include an anodic metal and a cathodic metal. The anodic metal and the cathodic metal can each form a fraction of a total surface area of the mesh.

Medical device delivery assemblies are disclosed. The assembly may include a catheter-based delivery system. The assembly may include a pacing element to pace a patient's heart before, during, or after a procedure. The pacing element may be a detachable, implanting pacing element. The pacing element may be an implantable pacemaker and the implantable pacemaker may be disposed on a catheter-based delivery system. The assembly may include a prosthetic heart valve with one or more pacing elements on it. The pacing element may include a pacing strip or strips. These strips may be conductive or insulative. These strips may prevent, treat, or correct abnormal electrical communication in a heart.

A method of making a valve structure includes a step of rotating a mandrel and an electrodeposition target attached to the mandrel about a rotational axis of the mandrel. The target includes an exterior surface having at least one conductive surface portion and at least one non-conductive surface portion. The method also includes a step of electrodepositing a polymer matrix of a biodegradable, biocompatible polymer composition onto the at least one conductive surface portion and the at least one non-conductive surface portion of the exterior surface of the rotating electrodeposition target to form the valve structure.
