Abstract: The present invention is directed to a physiological recording device and, more particularly, to a physiological recording device that can be used without skin preparation or the use of electrolytic gels. The invention is further directed to an encouragement ring which stabilizes and helps situate the physiological recording device on a subject's skin to help provide a better electrical signal, increase surface area, and reduce and minimize noise and artifacts during the process of recording or monitoring a physiological signal. The invention is still further directed to surface features on a surface of the physiological recording device with a size and shape that will not substantially bend or break, which limits the depth of application of the recording device, and/or anchors the recording device during normal application. The invention is even further directed to a method for manufacturing a physiological recording device, and minimizing cost of manufacture.

Abstract: The present disclosure relates generally to the field of medical devices for treating heart disease. In particular, the present disclosure relates to medical devices, systems, and methods for delivering artificial chordae tendineae in a patient. A system for delivering a chordae tendineae into a heart may include a delivery catheter. A clamp catheter may be configured to translate through the delivery catheter. A spreader may be disposed on the clamp catheter. A first clamp may be at least partially contained in the spreader in a closed configuration and may be attached to the chordae tendineae. An anchor catheter may be configured to translate through the delivery catheter and may have an anchor attached to the chordae tendineae. A sheath may be extended over the anchor catheter and anchor and may be configured to restrain an arm of the anchor.

Abstract: A method for assembling a propshaft assembly. The method can include: providing a tubular member, the tubular member having an annular wall with an inside circumferential surface; twisting a damper; installing the twisted damper in the tubular member; untwisting the damper in the tubular member such that the damper engages the inside circumferential surface of the annular wall. A machine for assembling a propshaft assembly is also provided.

Abstract: A method for assembling a propshaft assembly. The method can include: providing a tubular member, the tubular member having an annular wall with an inside circumferential surface; pushing a first ram through the tubular member; loading a damper between the first ram and a second ram; twisting the damper between the first and second rams; moving the first and second rams to translate the twisted damper into the tubular member; untwisting the damper in the tubular member; and withdrawing the first and second rams from the tubular member. A machine for assembling a propshaft assembly is also provided.
