Integrated mechanical handle with quick slide mechanism
Owner:MEDTRONIC VASCULAR INC
Integrated mechanical handle with quick slide mechanism
A method of deploying a prosthesis includes engaging a hub assembly of a handle to a threaded outer surface of a slide shaft of the handle; rotating the hub assembly to cause axial translation of the hub assembly and a sheath coupled to the hub assembly to initiate deployment of the prosthesis; disengaging the hub assembly from the threaded outer surface by pivoting a thread tooth of the hub assembly out of threaded engagement with the threaded outer surface; and sliding the hub assembly on the slide shaft to further retract the sheath and complete deployment of the prosthesis.

Integrated mechanical handle with quick slide mechanism
A method of deploying a prosthesis includes restraining the prosthesis within a distal end of a sheath. A slide ring of a handle is rotated to initiate retraction of the sheath. In this manner, the prosthesis is initially very gradually released. The slide ring is then slid to complete retraction of the sheath and to deploy the prosthesis. In this manner, the sheath is easily and quickly retracted thus rapidly completing deployment of the prosthesis. Rapid deployment of the prosthesis facilitates faster procedure times, thus minimizing the period of time during which blood flow is occluded.

Lock and fold floor covering panels can be installed by angling a long locking edge into a previously installed row of panels and dropping or locking the projection of the tongue of the short side into the depression of the lower lip forming the groove in the short side. By incorporating a force increasing means in the fold joint, the width of the panels that can be installed with a lock and fold system can be increased beyond the conventionally accepted 3.5 inches. The fold joint is designed to permit it to be engaged, disengaged and reengaged without damaging the fold joint.

Portable timepiece
ActiveUS7137732B2Increase resistanceFrictional resistanceVisual indicationClockwork casesContact pressureEngineering
A portable timepiece has a bezel rotatably disposed on a case body, and an elastically deformable gasket interposed between the case body and the bezel in an elastically deformed state to exert a frictional force on the case body and the bezel sufficient to maintain the bezel in a stationary rotational position though permitting the bezel to be manually rotated to any desired position by overcoming the frictional force. One or more lock members are movably disposed on the bezel and contact a slip-preventing part provided on the case body. A manually rotatable holding ring engages with the lock members and is rotatable in one direction to increase the contact pressure between the lock members and the slip-preventing part to thereby prevent unintended rotation of the bezel, and is rotatable in the other direction to decrease the contact pressure to thereby permit manual rotation of the bezel by overcoming the frictional force exerted by the elastically deformed gasket. In this manner, inadvertent rotation of the bezel is prevented by structure other than the gasket thereby preventing undue wear of the gasket.

Portable timepiece
ActiveUS20050141347A1Large frictional resistanceIncrease resistanceVisual indicationClockwork casesEngineeringCover glass
To provide a portable timepiece capable of suppressing a bezel from carelessly rotating and deviating, without impairing a rotation operability of the bezel. An annular bezel is rotatably disposed around an annular protrusion part of a case band to whose inner periphery there is attached a cover glass. A gasket made of an elastic material, which makes the bezel stationary to a desirable rotated position with respect to the case band, is interposed between the bezel and the case band under a state giving a frictional force to these. A holding mechanism, which holds the bezel to a stationary state with respect to the case band and can release this holding state, is provided separately from the gasket. By this, a rotation operability of the bezel is made light by restricting the rotation of the bezel by means of the holding mechanism to thereby suppress a careless rotation of the bezel and thus by the fact that the gasket is caused not to bear a function suppressing the rotation of the bezel.
