Abstract
In various examples, an apparatus includes a gripping member including a body and a gripping portion attached to the body. The body includes a passage configured to accept a needle cannula 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 is rotatably attached to the gripping member. The coupling member is configured to selectively couple with a dilator. The coupling member includes a bore fluidly coupled with the passage, the bore being configured to accept the needle cannula within the bore.
Claims20
An apparatus comprising:
- a gripping member including a body and a gripping portion attached to the body, the body including a passage configured to accept a needle cannula within and extending distally from the passage, the passage including a proximal opening, the gripping member including:
- an open configuration in which the needle cannula is movable within the passage;
- and
- a closed configuration in which the gripping portion is positioned to at least partially cover the proximal opening of the passage to directly frictionally contact a surface of the needle cannula proximal to the needle cannula surface being received in the passage of the body of the gripping member to thereby grip the needle cannula and inhibit movement of the needle cannula within the passage;
- and
- a coupling member rotatably attached to the gripping member, the coupling member configured to selectively couple with a dilator, the coupling member including a bore fluidly coupled with the passage, the bore being configured to accept the needle cannula within the bore.
An apparatus comprising:
- a gripping member including a body and a gripping portion attached to the body, the body including a passage configured to accept a needle cannula within and extending distally from the passage, the passage including a proximal opening, the gripping member including:
- an open configuration in which the needle cannula is movable within the passage;
- and
- a closed configuration in which the gripping portion is positioned to at least partially cover the proximal opening of the passage to directly frictionally contact a surface of the needle cannula proximal to the needle cannula surface being received in the passage of the body of the gripping member to thereby grip the needle cannula and inhibit movement of the needle cannula within the passage;
- and
- a dilator rotatably attached to the gripping member, the dilator including a lumen fluidly coupled with the passage, the lumen being configured to accept the needle cannula within the lumen.
An apparatus comprising:
- a gripping member including a body and a gripping portion attached to the body, the body including a passage configured to accept a needle cannula within and extending distally from the passage, the passage including a proximal opening, the gripping member including:
- an open configuration in which the needle cannula is movable within the passage;
- and
- a closed configuration in which the gripping portion is positioned to at least partially cover the proximal opening of the passage to directly frictionally contact a surface of the needle cannula proximal to the needle cannula surface being received in the passage of the body of the gripping member to thereby grip the needle cannula and inhibit movement of the needle cannula within the passage;
- and
- a puncture member including:
- a first portion attached to the gripping member;
- a second portion movable with respect to the first portion;
- a potential energy storage member disposed between the first portion and the second portion;
- and
- an actuator operatively coupled to the potential energy storage member, wherein triggering of the actuator releases the potential energy storage member to move the first portion with respect to the second portion.
