Methods and devices for controlled delivery
Disclosed herein are exemplary medical devices for controlled delivery of material compositions, particularly occlusive, therapeutic, or diagnostic compositions.
1. A contraceptive device, comprising at least an insertion tube for providing at least one catheter; at least one catheter, comprising an end structure on a delivery end that maintains the delivery end in at least one uterine cornua and aids in localized delivery of the one or more compositions; a handle comprising a level, a receptacle for receiving a material cartridge and a slider for moving a catheter slide, wherein the catheter slide moves the at least one catheter in a proximal or distal direction; a system plunger controlled by a lock, wherein the lock is movable between position one and position 2 ; wherein the system plunger is reversibly coupled to a control rod, the control rod defining two sets of parallel connecting elements, one set comprising attachment elements for moving two air syringes, and a second set comprising positioning elements, for moving material plunger actuators; wherein the lock is movable between a first position and a second position, and, when the lock is in the first position, the system plunger and the control rod are coupled such that movement of the system plunger moves the control rod, and when the lock is in the second position, the system plunger and the control rod are uncoupled such that the system plunger can move independently of the control rod and optionally, the optional material cartridge, optionally positioned within the receptacle in the handle, and the optional material cartridge optionally containing a composition comprising an occlusive material.
2. The device of claim 1 , wherein the end structure is a cup, nozzle, or a balloon.
3. The device of claim 1 , further comprising a material cartridge.
4. The device of claim 1 further comprising a material cartridge containing the composition comprising an occlusive material.
5. The device of claim 1 , wherein the material cartridge is positioned within the receptacle of the handle and wherein the material cartridge contains the composition comprising an occlusive material.
6. The device of claim 1 , wherein the composition comprising an occlusive material comprises a biodegradable cyanoacrylate composition.
7. The device of claim 1 , wherein the composition, when cured, swells less than 20%.
8. The device of claim 1 , wherein the composition is about 20% to about 100% substantially resorbed in a range of about 30 to about 365 days.
9. The device of claim 1 , wherein the composition further comprises tissue scarring agents, fibrosis agents, fertilization inhibitors, contraceptive agents, tissue growth promoters, hormones, polymerization inhibitors, polymerization stabilizers, emulsifying agents, echogenic agents, contrast agents, viscosity-modifying materials, plasticizers, colorants or combinations thereof.
10. The device of claim 1 , wherein the composition further comprises a curable carrier for the occlusive materials, a control release agent, tissue scarring agents, fibrosis agents, fertilization inhibitors, contraceptive agents, tissue growth promoters, hormones, polymerization inhibitors, polymerization stabilizers, emulsifying agents, echogenic agents, contrast agents, viscosity-modifying materials, plasticizers, colorants or combinations thereof.
11. The device of claim 4 , wherein the composition comprising an occlusive material comprises a biodegradable cyanoacrylate composition.
12. The device of claim 4 , wherein the composition, when cured, swells less than 20%.
13. The device of claim 4 , wherein the composition is about 20% to about 100% substantially resorbed in a range of about 30 to about 365 days.
14. The device of claim 4 , wherein the composition further comprises tissue scarring agents, fibrosis agents, fertilization inhibitors, contraceptive agents, tissue growth promoters, hormones, polymerization inhibitors, polymerization stabilizers, emulsifying agents, echogenic agents, contrast agents, viscosity-modifying materials, plasticizers, colorants or combinations thereof.
15. The device of claim 4 , wherein the composition further comprises a curable carrier for the occlusive materials, a control release agent, tissue scarring agents, fibrosis agents, fertilization inhibitors, contraceptive agents, tissue growth promoters, hormones, polymerization inhibitors, polymerization stabilizers, emulsifying agents, echogenic agents, contrast agents, viscosity-modifying materials, plasticizers, colorants or combinations thereof.
16. The device of claim 5 , wherein the composition comprising an occlusive material comprises a biodegradable cyanoacrylate composition.
17. The device of claim 5 , wherein the composition, when cured, swells less than 20%.
18. The device of claim 5 , wherein the composition is about 20% to about 100% substantially resorbed in a range of about 30 to about 365 days.
19. The device of claim 5 , wherein the composition further comprises tissue scarring agents, fibrosis agents, fertilization inhibitors, contraceptive agents, tissue growth promoters, hormones, polymerization inhibitors, polymerization stabilizers, emulsifying agents, echogenic agents, contrast agents, viscosity-modifying materials, plasticizers, colorants or combinations thereof.
20. The device of claim 5 , wherein the composition further comprises a curable carrier for the occlusive materials, a control release agent, tissue scarring agents, fibrosis agents, fertilization inhibitors, contraceptive agents, tissue growth promoters, hormones, polymerization inhibitors, polymerization stabilizers, emulsifying agents, echogenic agents, contrast agents, viscosity-modifying materials, plasticizers, colorants or combinations thereof.
