Abstract
A medical device may include a needle, including a plurality of links and a distal tip, reciprocally movable between a first configuration and a second configuration, and a conduit including a lumen extending through the needle, the conduit being coupled to the distal tip, wherein longitudinal movement of the conduit is configured to transition the needle between the first configuration and the second configuration.
Claims19
A medical device, comprising:
- a tool including at least a first link and at least a second link, the tool having a loose configuration and a rigid configuration, with the first link and the second link movable relative to one another when the tool is in the loose configuration;
- a conduit extending through each of the first link and the second link, wherein the tool moves between the loose configuration and the rigid configuration in response to movement of the conduit relative to the tool, wherein the first link and the second link are aligned straight relative to one another when the tool is in the rigid configuration;
- and
- a lumen extending through the conduit configured to provide fluid flow through each of the first link and the second link;
- wherein the first link and the second link are spaced apart from one another when in the loose configuration such that the tool includes a gap between the first link and the second link.

A medical device, comprising:
- a tool, including a plurality of links movable between a loose configuration of the tool and a rigid configuration of the tool, wherein adjacent links of the plurality of links are spaced apart from one another, such that a gap is between the adjacent links, when the tool is in the loose configuration;
- a conduit coupled to the plurality of links such that the conduit is configured to move relative to each of the plurality of links, wherein the conduit is configured such that proximal movement of the conduit relative to the plurality of links causes the tool to move from the loose configuration to the rigid configuration, and distal movement of the conduit relative to the plurality of links causes the tool to move from the rigid configuration to the loose configuration, wherein each of the plurality of links is configured to move along an exterior of the conduit when the tool is in the loose configuration;
- a lumen extending through the conduit;
- and
- a distal tip positioned distally from the plurality of links, wherein the conduit is configured to provide fluid flow through each of the plurality of links and the distal tip.
2 more elements
A medical device, comprising:
- a tool including a proximal link, a distal link, and a distal tip positioned distally from the proximal link and the distal link, wherein the proximal link and the distal link are movable relative to one another when the tool is in a loose configuration;
- and
- a conduit including a lumen that extends through the tool, wherein the conduit is configured to provide fluid flow through each of the links and the distal tip;
- wherein the proximal link and the distal link are disposed about, and movable over the conduit absent movement of the conduit relative to the tool, wherein the distal link is fully disengaged and not contacting the proximal link when the tool is in the loose configuration, and engaged with the proximal link when the tool is in a rigid configuration;
- wherein the proximal link and the distal link are aligned straight relative to one another when the tool is in the rigid configuration in response to movement of the conduit relative to the tool.
