Abstract
Provided are drainage systems that may include a drainage manifold and may be suitable for draining fluid from a tissue site. The drainage manifold may include a plurality of elongate members having a moveable end that may be adapted to configure the drainage manifold to treat a uniquely shaped tissue site. The drainage manifold may be coupled to a drainage tube with a transitional connector to provide a drainage system capable of distributing reduced pressure to the tissue site to enhance the drainage of fluids.
Core Innovation
The invention is an adaptable wound drainage system for draining fluid from a tissue site. It includes a drainage manifold with a longitudinal axis and a support positioned along the longitudinal axis, and the manifold has a plurality of elongate, movable members that shift between a gathered configuration and a dispersed configuration so the members can conform to uniquely shaped or multi-dimensional tissue sites.
Each member includes a lumen and an outer wall with an opening disposed through the outer wall, providing fluid communication from the tissue site to the drainage manifold. A web connects the outer wall to the support, and the web can releasably secure the members in the gathered configuration. In the dispersed configuration, the arrangement of the openings and lumens allows fluid to be extracted from the tissue site toward a reduced-pressure source.
The manifold is coupled to a drainage tube by a transitional connector to establish fluid communication between the drainage tube and the lumens of the members and/or the support. The disclosed embodiments may include a reduced-pressure source and a fluid canister that collects extracted fluid. Additional embodiments include configurations where the members are separated from the support by applying force to sever the web, enabling hand configuration via a single incision.
Claims Coverage
The partial content includes three independent claims for two drainage systems and one method. Across these independent claims, the inventive coverage centers on a drainage manifold with a longitudinal-axis support, members with lumens and outer-wall openings connected to the support by a web, member movement between gathered and dispersed positions, and, for one independent claim, severing the web to place the dispersed members at a target tissue site under reduced pressure.
Drainage manifold with longitudinal-axis support and web-connected members with lumens and outer-wall openings
A drainage system for draining fluid from a tissue site including a drainage tube; a drainage manifold having a support positioned on a longitudinal axis; and a plurality of members, each member having a lumen, an outer wall, a web connecting the outer wall to the support, and an opening disposed through the outer wall.
Method of removing fluid using reduced pressure and severing a web to disperse members at a target site
A method of removing fluid from a target site by coupling a drainage manifold to a reduced pressure source, where the drainage manifold includes a support positioned on a longitudinal axis and a plurality of members each comprising a web connecting the member to the support, severing the web of a member to move the member from a gathered position to a dispersed position, and placing the member at the target site in the dispersed position.
Movable drainage-manifold members having lumens and outer-wall openings with gathered-to-dispersed movement
A drainage system for draining fluid from a tissue site including a drainage manifold; a support positioned on a longitudinal axis; and a plurality of members, each member having a lumen, a first end and a second end where the first end is movable between a gathered position and a dispersed position relative to the support, a web connecting the outer wall to the support, and an opening disposed through the outer wall.
Across the independent claims, the core inventive structure is a longitudinal-axis drainage manifold with a support and web-connected, movable members that include lumens and outer-wall openings. The independent method claim further requires coupling the manifold to a reduced pressure source, severing the web to disperse the members, and placing the dispersed members at the target site.
Stated Advantages
Conforms to uniquely shaped or multi-dimensional tissue sites.
Intended to resist collapse.
Facilitates sealing/withdrawal.
Designed to reduce patient trauma and pain.
Documented Applications
Draining fluid from a tissue site, including target sites defined as tissue sites having one or more cavities, multiple tissue layers, and/or an incision.
