Abstract:
1. A tissue clipping device, comprising: a distal portion sized and shaped for insertion into a body lumen, the distal portion including a clip having a first clip arm, a proximal end of the clip movably housed within a lumen of a capsule extending longitudinally from a proximal end to a distal end such that the clip is movable relative to the capsule between a tissue receiving configuration in which the first clip arm extends distally from a distal end of the capsule in a biased open position and a tissue gripping configuration in which the first arm is retracted proximally within the capsule, the capsule including a first window extending laterally through a proximal end thereof; a bushing extending from a proximal end to a distal end and including a channel extending therethrough, the distal end including a first bushing arm extending distally therefrom such that the first bushing arm is releasably engagable with the first window of the capsule; and a core member received within the capsule and coupled to a proximal end of the clip arms, the core member including a locking portion and a first engaging element, the locking portion sized and shaped to be received within the channel of the bushing to apply a radially outward pressure to the first bushing arm such that the first bushing arm engages the first window of the capsule, the first engaging element extending radially outward from a portion of the core member distal of the locking portion such that the first engaging elements engages the first bushing arm to deform the first bushing arm radially inward and out of engagement with the first window of the capsule.
