A catheter configured for use with a vacuum source for removing fluid from a tissue, the catheter includes an elongated tube with a proximal end, a distal end, an outer wall positioned circumferentially along the length of the tube, and an inner wall positioned circumferentially along the length of the tube defining a lumen within the tube. The inner wall forms a suction channel along the length of the tube. The catheter includes one or more apertures defined along the tube. The one or more apertures extend from the outer wall of the tube to the inner wall of the tube. The one or more apertures are present at or near the distal end of the tube. The one or more apertures is/are in communication with the at least one suction channel. The catheter includes a vacuum port in communication with the proximal end of the tube. The vacuum port is operatively connected to the at least one suction channel and is capable of operative connection to the vacuum source. The suction channel is configured to allow fluid present within a space in a body to enter the one or more apertures in communication with the at least one suction channel and be removed via the at least one suction channel when the vacuum source is operatively attached to the vacuum port. A delivery channel is defined within the tube and positioned along the length of the tube. The one or more apertures is/are in communication with the delivery channel. One or more concave grooves are defined on the outer wall and extend along at least part of the length of the tube.
