Abstract

A medical system may include an insertion device including a delivery shaft with at least one lumen, a tube coupled to an exterior of the delivery shaft, and an adaptor coupling a distal end of the delivery shaft to a distal end of the tube. One of the delivery shaft and the tube may be configured to receive an energy delivery device, and the other of the delivery shaft and the tube may be configured to be coupled to a suction source to apply suction.

First claim

We claim:

1. A medical system, comprising:
an insertion device including a delivery shaft with at least one lumen;
a tube coupled to an exterior of the delivery shaft, wherein the tube includes a lumen; and
an adaptor coupling a distal end of the delivery shaft to a distal end of the tube, the adaptor comprising a first lumen coupled to the lumen of the tube and a second lumen coupled to the lumen of the delivery shaft,
wherein one of the delivery shaft and the tube is configured to receive an energy delivery device,
wherein the other of the delivery shaft and the tube is configured to be coupled to a suction source to apply suction,
wherein the first lumen of the adaptor is connected to the second lumen of the adaptor via at least one aperture, and
wherein the aperture includes a screen, a mesh, a strainer, a sieve, a filter, or a sifter.

2. The medical system of claim 1 , wherein a central longitudinal axis of the lumen of the tube is parallel to a central longitudinal axis of a lumen of the delivery shaft.

3. The medical system of claim 1 , wherein the aperture includes an opening that is smaller than a cross-sectional area of one of the lumen of the tube or the lumen of the delivery shaft, and wherein the tube includes one or more fluid delivery openings located proximal to a coupling with the adaptor.

4. The medical system of claim 1 , wherein at least one lumen of the adaptor includes a proximally tapered cross-section.

5. The medical system of claim 1 , wherein the tube is coupled to the delivery shaft via an outer sheath.

6. The medical system of claim 1 , wherein the tube is coupled to the delivery shaft via an adhesive.

7. The medical system of claim 1 , wherein the adaptor is coupled to the distal ends of the delivery shaft and the tube via a friction fit.

8. The medical system of claim 1 , wherein the delivery shaft includes a visualization device.

9. The medical system of claim 8 , wherein the adaptor includes a visualization opening at least partially aligned with the visualization device.

10. The medical system of claim 1 , wherein the adaptor is formed of an at least partially transparent material.

11. The medical system of claim 1 , further comprising a retrieval device configured to be positioned within either the lumen of the delivery shaft or the lumen of the tube.

12. The medical system of claim 1 , further comprising an end cap with a filter portion and an opening.

13. An adaptor for a medical system, comprising:
a first coupling portion configured to couple a tube to a first lumen of the adaptor;
a second coupling portion configured to couple a delivery shaft to a second lumen of the adaptor; and
an aperture fluidly connecting the first lumen to the second lumen,
wherein the first lumen and the second lumen are parallel,
wherein the first lumen of the adaptor is connected to the second lumen of the adaptor via at least one aperture, and
wherein the aperture includes a screen, a mesh, a strainer, a sieve, a filter, or a sifter.

14. The adaptor of claim 13 , wherein the first lumen includes a closed distal end, and wherein the second lumen includes an open distal end defining a cavity.

15. The adaptor of claim 14 , wherein the cavity of the second lumen is proximally tapered, and wherein a proximal portion of the cavity is adjacent to the aperture.

16. A method, comprising:
coupling a distal end of a delivery shaft to a distal end of a tube via an adaptor, the adaptor comprising a first lumen coupled to the lumen of the tube and a second lumen coupled to the lumen of the delivery shaft;
delivering the delivery shaft, the tube, and the adaptor to a body cavity;
applying suction to the body cavity through a lumen of the delivery shaft or a lumen of the tube to remove an object via an aperture within the adaptor or to retain the object adjacent to the aperture within the adaptor; and
delivering energy to the body cavity through the lumen of the delivery shaft or the lumen of the tube
wherein the first lumen of the adaptor is connected to the second lumen of the adaptor via at least one aperture, and
wherein the aperture includes a screen, a mesh, a strainer, a sieve, a filter, or a sifter.

17. The method of claim 16 , wherein the step of delivering the delivery shaft, the tube, and the adaptor to the body cavity includes positioning a guidewire within the lumen of at least one of the delivery shaft or the tube and advancing at least one of the delivery shaft, the tube, and the adaptor along the guidewire,
wherein the step of delivering energy to the body cavity further includes applying suction to the body cavity; and
wherein the method further comprises repositioning the delivery shaft, the tube, and the adaptor to another position within the body cavity and repeating the apply suction step and the energy delivery step.
