1. A drainage catheter for use in providing a fluid pathway for draining bodily fluid from a cavity or tissue of a patient, the drainage catheter being configured such that a suture utilized in connection with the drainage catheter selectively secures the distal end of the catheter in an anchor configuration, the drainage catheter comprising:
a catheter tube having a proximal end and a distal end, the distal end of the catheter tube being configured to be positioned in tissue, cavity, or other location within the body of the patient having an amount of fluid to be drained, the catheter tube comprising a distal end portion comprising a continuously decreasing outside diameter along a longitudinal direction to the distal end;
a suture running the length of at least a portion of the catheter tube and being secured to the distal end of the catheter tube to selectively maintain the anchor configuration of the distal end of the catheter;
a catheter hub coupled to the proximal end of the catheter tube, the catheter hub being configured to secure the suture to maintain the anchor configuration of the distal end of the catheter and release the suture to release the anchor configuration of the distal end of the catheter; and
a fixed-diameter sleeve configured to move axially along the catheter tube without requiring rotational movement of the sleeve, the sleeve being adapted to slide over the distal end of the catheter tube thereby straightening the catheter tube from a curved configuration into a straight configuration such that a rigid elongate member may be placed inside of the catheter to straighten the distal end of the catheter so as to facilitate the introduction or removal of the catheter relative to the patient, wherein the rigid elongate member is at least one of a cannula or a trocar; the sleeve further comprising lip disposed on a distal end of the sleeve, wherein the lip:
extends circumferentially around the longitudinal axis of the drainage catheter;
has a greater external diameter than an external diameter of a portion of the sleeve immediately proximal of the lip;
presents a smooth, rounded surface that extends from the most distal portion of the lip to the most lateral portion of the lip, wherein the most distal portion of the lip and the most lateral portion of the lip are different portions; and
facilitates movement of the catheter tube proximally with respect to the sleeve by presenting a smooth interface between the sleeve and the catheter tube; and
wherein the sleeve is removable from the catheter by distal displacement of the sleeve beyond the distal end of the catheter.
2. The drainage catheter of claim 1, wherein the distal end of the tube body is configured to be secured in a pig-tail position.
3. The drainage catheter of claim 1, wherein the tube body is at least partially biased into a pig-tail position.
4. The drainage catheter of claim 1, wherein the tube body is a soft, pliable material.
5. The drainage catheter of claim 1, wherein the lip includes a rounded portion on the inside of the sleeve.
6. The drainage catheter of claim 1, wherein the lip comprises a gradually expanding projection extending from the sleeve such that a portion of the lip has a greater inside diameter than the sleeve.
7. A catheter kit having drainage catheter for use in providing a fluid pathway for draining bodily fluid from a cavity or tissue of a patient, the drainage catheter being configured such that a suture utilized in connection with the drainage catheter selectively secures the distal end of the catheter in an anchor configuration, the catheter kit comprising:
a drainage catheter, the drainage catheter including:
a catheter tube having a proximal end and a distal end, the distal end of the catheter tube being configured to be positioned in tissue, cavity, or other location within the body of the patient having an amount of fluid to be drained, the distal end of the catheter tube comprising a non-flaring end;
a suture running the length of at least a portion of the catheter tube and being secured to the distal end of the catheter tube to selectively maintain the anchor configuration of the distal end of the catheter;
a catheter hub coupled to the proximal end of the catheter tube, the catheter hub being configured to secure the suture to maintain the anchor configuration of the distal end of the catheter and release the suture to release the anchor configuration of the distal end of the catheter;
at least two elongate rigid members such as a cannula or trocar, the at least two elongate rigid members, each of the at least two elongate rigid members being configured to be slidably received within the tube; and
a fixed-diameter sleeve configured to move axially along the catheter tube, the sleeve being adapted to slide over the distal end of the catheter tube thereby straightening the catheter tube from a curved configuration into a straight configuration to facilitate entry of at least one of the two elongate rigid members inside of the catheter tube to straighten the distal end of the catheter allowing a distal portion of one or both of the at least two elongate rigid members to extend to the distal end of the catheter tube without catching or damaging the distal portion of the catheter tube and to allow the introduction or removal of the catheter relative to the patient, the sleeve further comprising a lip disposed on an distal end of the sleeve, wherein the lip:
