GUIDE WIRE HOLDER
20210085930 · 2021-03-25 · ·

A guide wire holder includes a sheath having a lumen, an operation wire inserted into the lumen and configured to be able to advance and retract in the lumen, and a hook continuous with a distal end of the operation wire, being formed to be bent in a convex shape toward a distal side, and protrudes from a distal end of the sheath. The sheath has a side surface extending from the distal end of the sheath to a proximal end side in a direction of the longitudinal axis. The hook intersects a ridge line of the side surface and forms a closed region closed by the hook and the ridge line in a front view. The guide wire holder is configured to hold the guide wire located outside the sheath in the closed region in a state that the hook is disposed at a retracted position at which the hook is retracted.

WEDGE-LOCK SHEATH RETENTION MECHANISM

A medical device system may include a sheath, a pusher wire, and a locking element. The pusher wire may be slidably disposed within a lumen of the sheath. The locking element may have a proximal end, a distal end, an intermediate region disposed between the proximal end and the distal end, and a lumen extending from the proximal end to the distal end. The locking element may have a first inner diameter adjacent to the distal end and a second inner diameter adjacent to the proximal end, the second inner diameter smaller than the first outer diameter. The distal end region of the locking element may be configured to freely slide over the sheath and when a proximal end region of the locking element is disposed over the sheath, the locking element may be configured to depress the sheath radially inwards.
