Vacuum therapy devices and methods

Abstract

A vacuum therapy device for treatment of a defect internal of a human or animal body, the device comprising: a porous medium for treatment of the defect; a catheter having a proximal end and a distal end, wherein the catheter is configured to be inserted into the body to enable deployment of the porous medium through an opening at the distal end for treatment of the defect; and a suction element within the catheter, the suction element comprising a suction tube connected to the porous medium to provide suction thereat; wherein the porous medium is movable between: (i) a proximal position in which a majority of the porous medium is inside the catheter for insertion of the catheter and the porous medium into the body, and (ii) a distal position in which a portion of the porous medium is located outside the catheter for treatment of the defect; wherein a cross-section of the shape of the porous medium includes one or more spokes extending radially outward, wherein two adjacent spokes are separated by a separation region, wherein the separation region is more flexible and/or compressible than the spokes.
