Sealing assemblies and methods are disclosed for sealing a surgical instrument having an internal drive shaft subject to lateral displacement. A sealing assembly includes a rigid portion shaped to interface with an instrument shaft of the surgical instrument. A laterally oriented slot is open at a radially perimeter location and configured to receive an o-ring seal via the perimeter location. Apertures are disposed on opposing sides of the slot and open to the slot. The apertures are configured to receive the drive shaft there through and are larger than the drive shaft to accommodate lateral displacement of the drive shaft. The slot includes opposing internal sides spaced to interface with opposed axial surfaces of the o-ring seal. The seal inhibits axial transmission of an insufflated gas and / or bodily fluids while accommodating lateral displacement of the drive shaft.

A control system is provided for use in a power tool. The control system includes: a rotational rate sensor having a resonating mass and a controller electrically connected to the rotational rate sensor. The rotational rate sensor detects lateral displacement of the resonating mass and generates a signal indicative of the detected lateral displacement, such that the lateral displacement is directly proportional to a rotational speed at which the power tool rotates about an axis of the rotary shaft. Based on the generated signal, the controller initiates a protective operation to avoid further undesirable rotation of the power tool. The control scheme employed by the power tool may initiate different protective operations for different tool conditions.

A tibia plateau for a replacement joint, particularly an endoprosthesis for a human knee joint, in which the head and socket artificial joint parts have convex and concave articulation surfaces, respectively, and the articulation surfaces are arranged in pairs, so that the functional surfaces which are formed can roll against one another along a curved contact line, especially a circularly arcuate contact line, formed on each articulation surface. A gently sloping bulge (1) is formed in the area (4) adjacent the functional surfaces (2) which bulge prevents excessive rolling movement and lateral displacement of the joint parts relative to each other.

Devices and methods are provided for reducing the lateral displacement of an endovascular device, e.g. a stent graft, within an aneurysm sac.

A method for determining a borehole azimuth in a borehole is disclosed. In one exemplary embodiment, the method includes acquiring at least one standoff measurement and a tool azimuth measurement at substantially the same time. Such measurements are then processed, along with a lateral displacement vector of the downhole tool upon which the sensors are deployed in the borehole, to determine the borehole azimuth.
