Abstract: The present disclosure relates to IL-34 antibodies, compositions comprising the same, and methods of using the antibodies and or compositions thereof for treating immune-mediated diseases such as neurodegenerative diseases, for example Alzheimer's Disease or a tauopathy disease.

Abstract: An exemplary system for delivering annuloplasty implants includes an elongated inner catheter assembly, a manifold attached to the proximal portion of the inner catheter, a steering knob assembly coupled to the manifold, a torquer control knob assembly coupled to the manifold, and a central lead extending from a proximal portion of the torquer control knob assembly to the distal portion of the inner catheter assembly. The manifold is configured to present a medial driver tube, a lateral driver tube, a medial lead, a lateral lead, a medial tether puller and a lateral tether puller to a surgeon. Additional annuloplasty implant instrumentation and methods of use are also disclosed.

Abstract: An exemplary method of performing an annuloplasty procedure includes introducing a catheter into a left atrium of a heart, deploying first and second members from the catheter and anchoring them to an anterior side of a mitral valve, and deploying a third member from the catheter and anchoring it to a posterior side of the mitral valve. The first member has a first flexible tensile member attached and the second member has a second flexible tensile member attached. The third member slidably tracks over the first and the second flexible tensile members when it is being deployed. Tension is applied to the first and the second tensile members to draw the first member and the second member toward the third member, thereby bringing the posterior side and the anterior side of the mitral valve annulus into closer approximation. Annuloplasty systems, devices and components are also disclosed.
