Abstract
The disclosed technology includes irrigation manifold that routes irrigation fluid to an end effector for a medical device. The irrigation manifold includes a housing and a diverter that extend along a longitudinal axis and respectively connect with irrigation tubes. The end effector includes jackets that each define an irrigation conduit connecting with the irrigation manifold to allow an even distribution of irrigation fluid flow through the jackets.
Claims16
An irrigation system for a medical device, the irrigation system comprising:
- an irrigation manifold comprising:
- a housing defining a housing conduit and extending along a longitudinal axis;
- and
- a diverter connecting with the housing to define an annular irrigation chamber and defining a plurality of diverter conduits;
- a main line irrigation tube connected to the housing conduit and configured to connect with a fluid source;
- a plurality of diverter irrigation tubes, each connected to a respective diverter conduit, the plurality of diverter irrigation tubes being configured to route a fluid to an end effector of the medical device;
- and
- further comprising the end effector, the end effector comprising a plurality of spines disposed about the longitudinal axis, each spine comprising a proximal end connected to the irrigation manifold, the end effector further comprising a plurality of jackets, each jacket defining:
- a spine channel receiving a respective spine of the plurality of spines;
- and
- an irrigation conduit that receives a respective diverter irrigation tube of the plurality of diverter irrigation tubes, the plurality of diverter irrigation tubes comprising first diverter irrigation tubes and second diverter irrigation tubes, each first diverter irrigation tube being received by the irrigation conduit of a respective jacket of the plurality of jackets, and each second diverter irrigation tube comprising a distal end disposed outside the plurality of jackets.
