Abstract
A laparoscopic device comprising: (a) a housing operatively coupled to a first control and a second control; (b) an end effector operatively coupled to the first control, the end effector comprising a first component and a second component selectively repositionable with respect to one another within an X-Y plane, the end effector also including a third component selectively repositionable with respect to the second component within an Y-Z plane; (c) a laparoscopic conduit extending between the housing and the end effector; and, (d) an occlusion clip deployment device operatively coupled to the end effector and the second control.
Core Innovation
The disclosed subject matter relates to a laparoscopic device for deploying an occlusion clip. A housing is operatively coupled to a first control and a second control, where the first control includes a lever repositionable with respect to the housing and the second control includes a button repositionable with respect to the housing. An elongated shaft extends from the housing to an end effector at a distal end of the elongated shaft, and the occlusion clip is removably coupled to the end effector and is repositionable between an open position and a closed position, where the occlusion clip is biased toward the closed position.
The lever is operatively coupled to the end effector via a first line extending through the elongated shaft, and the button is operatively coupled to the end effector via a second line extending through the elongated shaft. The controls move respective lines through routing paths that extend through the housing and along the elongated shaft to the distal end effector. Mechanical components described for deployment include a repositionable lever, a drive plate, and a return spring that reposition deployment wires to open and close a biased-closed occlusion clip.
The end effector and occlusion clip arrangement is configured so that opening allows insertion and closing inhibits insertion of a left atrial appendage between first and second beams. The occlusion clip includes a first beam and a second beam repositionable between an open position and a closed position, and the hollow elongated shaft and housing provide communication between openings of the hollow elongated shaft, the housing, and the end effector to route the lines. The document further describes end effector orientation as repositionable or locked in a static orientation.
Claims Coverage
The partial content provides three independent claims. Across these independent claims, the inventive features focus on a biased-closed occlusion clip removably coupled to a distal end effector, a two-control actuation using lines routed through a housing and elongated shaft, and the functional opening and closing behavior relative to a left atrial appendage.
Lever-driven end effector actuation for biased-closed occlusion clip
A surgical device comprising a housing operatively coupled to a first control including a lever repositionable with respect to the housing, an elongated shaft extending from the housing, an end effector at a distal end, and an occlusion clip removably coupled to the end effector and repositionable between an open position and a closed position while being biased toward the closed position, where the lever is operatively coupled to the end effector via a first line extending through the elongated shaft.
Button-driven end effector actuation via second line through elongated shaft
A surgical device where a second control includes a button repositionable with respect to the housing and operatively coupled to the end effector via a second line extending through the elongated shaft.
Left atrial appendage occlusion with communicating hollow shaft openings
A surgical device having an occlusion clip removably coupled to an end effector with a first beam and second beam repositionable between open and closed positions and biased toward the closed position, where the open position allows insertion of a left atrial appendage between the first and second beams and the closed position inhibits insertion; a hollow elongated shaft extending from a proximal portion of the end effector to a distal portion of a housing; and wherein a proximal opening of the hollow elongated shaft is in communication with a distal opening of the housing and a distal opening of the hollow elongated shaft is in communication with a proximal opening of the end effector.
Handle repositioning to open and close biased-closed left atrial appendage occlusion clip
A method deploying a left atrial appendage occlusion clip using a medical device comprising a housing mounted to an elongated shaft, the elongated shaft mounted to a distal end effector, and the distal end effector removably mounted to a biased-closed occlusion clip, where repositioning a handle in a first direction with respect to the housing opens the biased-closed occlusion clip, and repositioning the handle in a second direction opposite the first direction closes the biased-closed occlusion clip and clamps a left atrial appendage.
The claim set centers on a laparoscopic occlusion-clip deployment arrangement in which a biased-closed occlusion clip is removably coupled to a distal end effector and opened and closed in relation to a left atrial appendage. Actuation is controlled by a housing-coupled lever and a housing-coupled button, each repositionable with respect to the housing and coupled to the distal end effector via lines routed through an elongated shaft, with hollow shaft communication supporting the routing. The method claim further recites opening and closing by repositioning the handle in first and second directions.
