Adhesive occlusion systems
System and methods of delivering adhesive material are described for occluding target locations within a patient. The systems include a catheter configured to deliver adhesive to a target location and one or more of a light source to harden the adhesive, a retention structure to contain the adhesive prior to curing, a balloon to occupy a target location, and an open cell foam plug to occupy a target location.
1. An occlusion device for treatment of a medical condition, comprising:
an elongated conduit having at least one passage between its proximal end and distal end, the elongated conduit conveying an inflation fluid; and
an inflatable balloon detachably connected to a distal portion of the conduit; the balloon being in communication with the at least one passage of the conduit to convey the inflation fluid to inflate the balloon;
wherein a distal region of the inflatable balloon comprises a plurality of pores;
wherein, in a non-inflated configuration, an adhesive is within an interior region of the inflatable balloon; and,
wherein, in an inflated configuration, at least a portion of the adhesive is delivered through at least some of the plurality of pores.
2. The occlusion device of claim 1 , wherein the distal region of the inflatable balloon comprises a porous membrane including the plurality of pores.
3. The occlusion device of claim 1 , further comprising a retention structure positioned proximal of the inflatable balloon.
4. The occlusion device of claim 3 , wherein the retention structure comprises a mesh braided device.
5. The occlusion device of claim 3 , wherein the retention structure comprises a metallic frame.
6. The occlusion device of claim 3 , wherein the retention structure comprises a polymeric structure.
7. The occlusion device of claim 3 , further comprising a light source insertable within the at least one passage so as to react with the adhesive.
8. The occlusion device of claim 3 , wherein the retention structure includes a detachment system for detaching the retention structure from the elongated conduit.
9. The occlusion device of claim 8 , wherein the detachment system is comprised of a thermal detachment system.
10. The occlusion device of claim 8 , wherein the detachment system is comprised of an electrolytic detachment system.
11. The occlusion device of claim 8 , wherein the detachment system is comprised of a mechanical detachment system.
12. The occlusion device of claim 3 , wherein the retention structure is positioned at or near the distal end of the elongated conduit.
13. The occlusion device of claim 1 , further comprising one or more check valves to prevent backflow as the inflatable balloon is inflated.
14. The occlusion device of claim 13 , wherein the one or more check valves are located in the conduit.
15. The occlusion device of claim 1 , further comprising a threaded detachment assembly removably connecting the inflatable balloon to the conduit.
16. The occlusion device of claim 15 , wherein the detachment assembly includes a threaded male portion engaged with a threaded female portion, such that rotation of the conduit detaches the conduit from the inflatable balloon.
17. An occlusion device, comprising:
a delivery means for conveying an inflation fluid, the delivery means having at least one passage between its proximal end and distal end; and
an inflation means in fluid communication with the at least one passage; and,
wherein a distal region of the inflation means comprises a plurality of pores;
wherein, in a non-inflated configuration, an adhesive is within an interior region of the inflation means;
wherein, in an inflated configuration, at least a portion of the adhesive is delivered through at least some of the plurality of pores.
18. The occlusion device of claim 17 , further comprising a retention means positioned proximal of the inflation means.
