The disclosure provides a release mechanism, method of manufacturing, and method of releasing a medical device. The mechanism comprises a generally elongate shaft, an actuating member receivable in the elongate shaft, the actuating member having an interlocking position and a releasing position, and at least two opposed arms at a distal end of the elongate shaft, biased to open relative to each other, each arm comprising a gripping portion at a distal end, and at least one interlocking member. The gripping portions of the arms may define a hollow space for holding a device. The interlocking member of each arm is longitudinally spaced from the interlocking member of any other arm and extends circumferentially around the actuating member. The actuating member is longitudinally retractable from the interlocking position to the releasing position to enable the arms to open for releasing a medical device from the gripping portions. |

1. A release mechanism for releasing a medical device, the release mechanism comprising:
a generally elongate shaft defining a longitudinal axis; an actuating member receivable in the elongate shaft, the actuating member having an interlocking position and a releasing position; and at least two, mutually opposed arms at a distal end of the elongate shaft, the arms being biased to open relative to each other, each arm comprising:
a gripping portion at a distal end thereof, andat least one interlocking member, wherein the gripping portions of the arms at least partially define a hollow space for holding a medical device to be released, the interlocking member of each arm is longitudinally spaced from the interlocking member of any other arm, each interlocking member extends circumferentially around a sufficient proportion of the actuating member such that, when the actuating member is in the interlocking position, opening of the arms is prevented by interaction between the actuating member and the interlocking members, and the actuating member is longitudinally retractable from the interlocking position to the releasing position to enable the arms to open for releasing a medical device from the gripping portions. |
