Abstract

A medical device includes a sheath having a proximal end, a distal end, and at least one lumen extending from the proximal end to the distal end, and a balloon at the distal end of the sheath and having an inflated configuration and a deflated configuration. The balloon defines at least one space radially inward of an exterior surface of the balloon, the at least one space configured to retain a material, and the transition of the balloon from the deflated configuration to the inflated configuration delivers the material from the at least one space to a target site in a body.

First claim

What is claimed is:

1. A medical device, comprising:
a sheath having a proximal end, a distal end, and at least one lumen extending from the proximal end to the distal end; and
only one balloon at the distal end of the sheath and having an inflated configuration and a deflated configuration,
wherein the only one balloon defines (1) only one balloon lumen both radially inward of an exterior surface of the only one balloon and configured to retain a first material for delivery of the first material onto a target site, and (2) a space in fluid communication with the at least one lumen of the sheath,
wherein the at least one lumen includes a sheath lumen,
wherein the medical device is configured to be attached to a fluid containment device,
wherein a fluid from the fluid containment device is configured to be supplied to the sheath lumen to transition the only one balloon from the deflated configuration to the inflated configuration,
wherein the only one balloon lumen is disposed within an inner wall and an outer wall of the only one balloon,
wherein the only one balloon lumen only partially circumferentially surrounds the space of the only one balloon, and
wherein the only one balloon includes a plurality of openings in the outer wall of the only one balloon fluidly coupled to the only one balloon lumen.

2. The medical device according to claim 1 , wherein the only one balloon does not include an outer coating of the first material in the deflated configuration.

3. The medical device of claim 1 , wherein the sheath is attached to a distal end of an actuating device.

4. The medical device of claim 3 , wherein the actuating device is a Y-shaped member including a first channel and a second channel.

5. The medical device of claim 4 , wherein a fluid travels through the first channel, inflating the only one balloon, wherein the fluid travels out of the only one balloon through the second channel, deflating the only one balloon.

6. The medical device of claim 5 , wherein the fluid containment device is configured to contain the fluid, the first channel is attachable to the fluid containment device, and the fluid travels from the fluid containment device through the first channel into the only one balloon, inflating the only one balloon;
wherein the second channel is attachable to the fluid containment device and the fluid travels from the only one balloon through the second channel into the fluid containment device, deflating the only one balloon.

7. The medical device of claim 6 , further comprising a catheter configured to contain the only one balloon and the sheath within a first opening, the catheter including a distal end face, the distal end face including a second opening and a third opening each fluidly connected to a lumen, wherein the second opening may supply fluid and the third opening may supply suction.

8. The medical device of claim 1 , wherein the only one balloon lumen is configured to deliver the first material and a second material; wherein delivery of the second material forces remaining amounts of the first material within the only one balloon lumen onto the target site in a body.

9. The medical device of claim 8 , wherein the second material is a different material from the first material, wherein the second material is configured to activate the first material.

10. The medical device of claim 9 , wherein a distal end of the only one balloon abuts a proximal end of a distal tip of the sheath.

11. The medical device of claim 8 , wherein the first material is an adhesive, and the second material is a solvent or a fluid configured to activate the first material.

12. The medical device of claim 1 , wherein a portion of the only one balloon lumen extends from a proximal end of the only one balloon and terminates prior to a distal tip of the sheath.

13. A medical device, comprising:
a shaft having a distal end;
a handle at a proximal end of the shaft, the shaft including a first lumen and a second lumen each with an opening at the distal end of the shaft, the opening of the first lumen configured to deliver fluid or suction;
the second lumen including:
a sheath having a proximal end, a distal end, and at least one lumen extending from the proximal end of the sheath to the distal end of the sheath; and
only one balloon at the distal end of the sheath and having an inflated configuration and a deflated configuration;

a first agent; and
a second agent different from the first agent and configured to activate the first agent;
wherein the only one balloon includes (1) a balloon lumen both radially inward of an exterior surface of the only one balloon and configured to retain the first agent for delivery of the first agent onto a target site, and (2) a space in fluid communication with the at least one lumen of the sheath,
wherein the at least one lumen of the sheath includes a sheath lumen,
wherein the medical device is configured to be attached to a fluid containment device,
wherein a fluid from the fluid containment device is configured to be supplied to the sheath lumen to transition the only one balloon from the deflated configuration to the inflated configuration,
wherein the balloon lumen is disposed within an inner wall and an outer wall of the only one balloon,
wherein the balloon lumen only partially circumferentially surrounds the space of the only one balloon,
wherein the only one balloon includes a plurality of openings in the outer wall of the only one balloon fluidly coupled to the balloon lumen, and
wherein the balloon lumen is configured to deliver the first agent and the second agent; wherein delivery of the second agent forces remaining amounts of the first agent within the balloon lumen onto the target site.

14. The medical device of claim 13 , wherein a portion of the balloon lumen extends from a proximal end of the only one balloon and terminates prior to a distal tip of the sheath.

15. The medical device of claim 13 , wherein the first agent includes an adhesive, and the second agent includes a solvent or a fluid.

16. The medical device of claim 13 , wherein the first agent includes an adhesive, and the second agent includes an adhesive.

17. The medical device of claim 13 , wherein the first agent is preloaded in the balloon lumen and includes an adhesive; wherein the second agent is supplied to the balloon lumen via a syringe; and wherein the second agent includes a solvent or a fluid.
