Abstract

A medical device that includes a first body including a first actuation member including a first connector and a second actuation member. The medical device includes a second body for attachment to, and detachment from, the first body. The second body including an actuation wire, a second connector at a proximal end of the actuation wire, and a valve having one or more channels for receiving a material. Attachment of the first body with the second body results in the first connector engaging the second connector, such that movement of the first actuation member causes a corresponding movement of the actuation wire. Moving the second actuation member into the second body to interact with the valve is configured to selectively direct the material through the one or more channels.

First claim

We claim:

1. A medical device, comprising:
a first body including:
a first actuation member including a first connector; and
a second actuation member;

a second body for attachment to, and detachment from, the first body, the second body including:
an actuation wire;
a second connector at a proximal end of the actuation wire; and
a valve having one or more channels for receiving a material;

wherein attachment of the first body with the second body results in the first connector engaging the second connector, such that movement of the first actuation member causes a corresponding movement of the actuation wire; and
wherein moving the second actuation member into the second body to interact with the valve is configured to selectively direct the material through the one or more channels.

2. The medical device of claim 1 , wherein the second actuation member is configured to close an opening of at least one of the one or more of channels by at least partially deforming the valve at the opening.

3. The medical device of claim 1 , wherein the second body includes a movable valve body disposed within the valve, the movable valve body being biased to a first position by a biasing mechanism positioned against the movable valve body.

4. The medical device of claim 3 , wherein the second actuation member is configured to compress the biasing mechanism and move the movable valve to a second position.

5. The medical device of claim 1 , wherein the first body includes a channel and the second body includes a fluidics tube configured to receive the material from a source, wherein the channel is configured to receive the fluidics tube through the first body.

6. The medical device of claim 1 , wherein the first body includes an actuator coupled to the first actuation member, and the second body includes a shaft coupled to a distal end of the actuation wire.

7. The medical device of claim 6 , wherein the actuator is configured to articulate the shaft in response to actuator moving the first actuation member, and the first actuation member moving the actuation wire, when the first connector is engaged with the second connector.

8. The medical device of claim 1 , wherein the first connector includes a grasper, and the second connector includes a pair of pins defining a gap sized to receive the grasper between the pair of pins.

9. The medical device of claim 8 , wherein the grasper is configured to engage the pair of pins by extending through the gap to couple the first actuation member to the actuation wire.

10. The medical device of claim 9 , wherein the grasper is configured to extend through the gap in response to the first body rotating in a first direction relative to the second body when the first body is at least partially received within the second body.

11. The medical device of claim 10 , wherein the grasper is configured to disengage the pair of pins from the grasper in response to the first body rotating in a second direction relative to the second body that is opposite of the first direction.

12. The medical device of claim 6 , wherein the actuation wire is configured to move relative to the second body in response to the first actuation member moving relative to the first body.

13. The medical device of claim 1 , wherein the first body includes an actuator coupled to a gear, and the first actuation member includes a gear rack configured to mesh with the gear.

14. The medical device of claim 13 , wherein the actuator is configured to translate the first actuation member and the first connector by rotating the gear.

15. The medical device of claim 1 , further including a locking mechanism having a pin on the first body, and an aperture on the second body that is configured to receive the pin when the first body is received within, and rotated relative to, the second body, thereby fixing an axial position of the first body relative to the second body.

16. A medical device, comprising:
a proximal handle including:
a handle housing including a channel;
an actuation rod disposed within and movable relative to the handle housing;
an actuator movably coupled to the actuation rod; and

a shaft assembly including:
a shaft housing including a fluidics tube extending proximally from the shaft housing, the fluidics tube configured to extend through the channel of the handle housing;
a valve manifold disposed within the shaft housing; and
at least one fluidics channel defined by the valve manifold and in fluid communication with the fluidics tube;

wherein the actuator is configured to control the fluid communication between the at least one fluidics channel and the fluidics tube by abutting the actuation rod against the valve manifold to at least partially deform the valve manifold.

17. The medical device of claim 16 , wherein the valve manifold includes a movable valve body and a biasing mechanism disposed within the valve manifold, wherein the movable valve body is biased to a default position when the biasing mechanism is in an expanded configuration; and
wherein the at least one fluidics channel is in fluid communication with the fluidics tube when the movable valve body is in the default position.

18. The medical device of claim 17 , wherein the actuator is configured to move the movable valve body to an actuated position by urging the biasing mechanism to a compressed configuration;
wherein the at least one fluidics channel is not in fluid communication with the fluidics tube when the movable valve body is in the actuated position.

19. The medical device of claim 16 , wherein the proximal handle includes a first connector and a second actuation rod coupled to the first connector, the first connector is movable relative to the handle housing in response to movement of the second actuation rod, and the shaft assembly includes a second connector and an actuation wire coupled to the second connector, the second connector is movable relative to the shaft housing in response to movement of the actuation wire; and
wherein the second actuation rod is configured to move the actuation wire when the first connector is mated with the second connector.

20. A medical device, comprising:
a first body including:
an actuator;
a movable rod coupled to the actuator and configured to move in response to actuation of the actuator; and

a second body selectively attachable to the first body, the second body including:
a valve having a flexible body; and
a plurality of channels configured to deliver a material through the second body;

wherein the actuator is configured to selectively divert the material through the plurality of channels in response to moving the movable rod against the valve to at least partially deform the flexible body.
