Abstract: Apparatus, for use at a valve of a heart of a subject, includes a first catheter, a second catheter, and a translation element. The translation element is connected to, and operatively joins, the distal ends of the first catheter and the second catheter. The translation element is operable to translate the distal ends laterally with respect to each other to transition the apparatus between (i) a first state in which the distal ends are held next to each other for transluminal advancement to the heart, and (ii) a second state in which the distal ends are spaced apart from each other for positioning at a first location on the annulus and a second location on the annulus, respectively. The apparatus is configured to, while in the second state, from the distal ends, anchor a first tissue anchor at the first location, and a second tissue anchor at the second location.

Abstract: An adjustable ski pole having a clamping mechanism for locking the pole in a desirable position. An outer shaft telescopically receives an inner shaft which is engaged by a clamping mechanism. The clamping mechanism includes a housing having a first portion attached to the outer shaft and a split portion defining a longitudinal gap. A circumferential slot separates the split portion from the first portion along about half the circumference. The split portion has a first lug on one side of the gap and a second lug on the other side. A lever is pivotably connected to the first lug. A link is pivotably connected to the lever to define an off-center linkage. A pivot rod engages the second lug, and a threaded connector adjustably connects the link to the rod. When the lever is pivoted from the release position to the clamping position, the gap width is reduced.
