Indwelling luminal devices
View Patent ↗The invention comprises an indwelling medical device which is capable of delivering a therapeutic agent evenly along the length of the indwelling portion, including the outer wall, of the device.
1. A medical device comprising:
a catheter comprising a central tube surrounded by an outer jacket,
wherein the central tube comprises at least one lumen and an outer surface having a plurality of grooves extending along the longitudinal axis of the central tube,
wherein the outer jacket and the grooves form a plurality of fluid channels extending along at least a portion of the longitudinal axis of the central tube,
wherein said outer jacket comprises ePTFE having a permeable microstructure, and
wherein a therapeutic agent perfuses through said outer jacket.
2. A medical device of claim 1 , wherein the central tube is segmented to contain the at least one lumen and a second lumen.
3. A medical device of claim 2 , wherein the at least one lumen and second lumen comprise a d-shaped cross section.
4. A medical device of claim 1 , wherein the distal end of the outer jacket comprises a plurality of expandable bent sections which expand into a larger diameter anchor section.
5. A medical device of claim 1 , wherein the outer surface of the central tube is generally circular.
6. A medical device comprising;
a catheter comprising a central tube surrounded by an outer jacket,
wherein the central tube comprises an outer surface with a plurality of grooves extending along the longitudinal axis of said tube,
wherein said grooves and said outer jacket form a plurality of channels extending along at least a portion of the longitudinal axis of said medical device,
wherein said outer jacket comprises ePTFE having a permeable microstructure, and
wherein a therapeutic agent perfuses through said outer jacket.
7. The medical device of claim 6 , wherein said central tube is internally segmented into a plurality of lumens.
8. The medical device of claim 6 , wherein said device comprises an indwelling catheter.
9. The medical device of claim 6 , wherein said device is a central venous catheter.
10. The medical device of claim 6 , wherein said lumens are each in fluid communication with an extension tube.
11. The medical device of claim 10 , wherein said extension tubes each comprise a connector hub.
12. The medical device of claim 10 , wherein said channels are in fluid communication with an extension tube.
13. The medical device of claim 10 , wherein said extension tube comprise a connector hub.
14. The medical device of claim 10 , wherein several extension tubes are attached to different channels.
15. The medical device of claim 10 , wherein at least two extension tubes are in fluid communication with different channels.
16. The medical device of claim 6 , wherein said central tube comprises two lumens.
