Transseptal needle apparatus

摘要

In various examples, an apparatus (110) includes a gripping member (120) including a body and a gripping portion attached to the body. The body includes a passage configured to accept a needle cannula (160) within the passage. The gripping portion includes an open configuration in which the needle cannula is movable within the passage and a closed configuration in which the gripping portion engages the needle cannula to inhibit movement of the needle cannula within the passage. A coupling member (130) is rotatably attached to the gripping member. The coupling member is configured to selectively couple with a dilator (140). The coupling member includes a bore fluidly coupled with the passage, the bore being configured to accept the needle cannula within the bore.
