Medical systems, devices, and related methods
In one example, a medical system may comprise a delivery tube configured to couple to a vacuum source and provide negative pressure to a distal portion of the delivery tube; and a porous body at a distal portion of the delivery tube, the porous body including a first section and a second section removable from the first section.
1. A medical system comprising:
a delivery tube configured to couple to a vacuum source and provide negative pressure to a distal portion of the delivery tube; and
a porous body at the distal portion of the delivery tube, the porous body including:
a first section,
a second section removable from the first section, and
a third section removable from the second section,
wherein the first section is nested within the second section,
wherein the second section is nested within the third section, and
wherein a length of the first section is shorter than lengths of each of the second and third sections.
2. The medical system of claim 1 , wherein the second section extends circumferentially around the first section, and wherein the third section extends circumferentially around the second section.
3. The medical system of claim 1 , wherein the first section, the second section, and the third section are concentric.
4. The medical system of claim 1 , wherein the first section is coupled to the delivery tube.
5. The medical system of claim 1 , wherein the first section has a cylindrical shape.
6. The medical system of claim 1 , wherein each of the first section, the second section, and the third section has a different thickness measured orthogonally to a central longitudinal axis of the porous body.
7. The medical system of claim 1 , further comprising a layer of one of an adhesive, a mesh, or an agent disposed between each of the first section and the second section and the second section and the third section.
8. The medical system of claim 1 , further comprising a string coupled to the second section and the third section.
9. The medical system of claim 8 , wherein the string extends from the porous body to a proximal portion of the delivery tube, and wherein the string includes:
a first portion coupled to the second section and the third section,
wherein the first portion has a length longer than a length of the delivery tube; and
a second portion coupled to the third section and extending proximally to the proximal portion of the delivery tube.
10. A medical system comprising:
a delivery tube configured to couple to a vacuum source and provide negative pressure to a distal portion of the delivery tube; and
a porous body at the distal portion of the delivery tube, the porous body including:
a first section,
a second section extending circumferentially around the first section, and
a third section extending circumferentially around the second section,
wherein the first section is nested within the second section,
wherein the second section is nested within the third section, and
wherein a length of the first section is shorter than lengths of each of the second and third sections.
11. The medical system of claim 10 , wherein the first section, the second section, and the third section are concentric.
12. The medical system of claim 10 , wherein the first section has a cylindrical shape.
13. The medical system of claim 10 , wherein each of the first section, the second section, and the third section extends 360° circumferentially around a central longitudinal axis of the delivery tube.
14. The medical system of claim 10 , wherein each of the first section, the second section, and the third section extends less than 360° around a central longitudinal axis of the delivery tube.
15. The medical system of claim 10 , wherein the second section is separated from the first section by a first perforation, and wherein the third section is separated from the second section by a second perforation.
16. The medical system of claim 10 , further comprising a string coupled to the second section and the third section.
17. A medical system comprising:
a delivery tube configured to couple to a vacuum source and provide negative pressure to a distal portion of the delivery tube; and
a porous body at the distal portion of the delivery tube, the porous body including:
a first section, the first section having a cylindrical shape,
a second section extending circumferentially around the first section, and
a third section extending circumferentially around the second section,
wherein each of the first section, the second section, and the third section extends 360° circumferentially around a central longitudinal axis of the delivery tube, and
wherein a length of the first section is shorter than lengths of each of the second and third sections.
18. The medical system of claim 17 , wherein the first section, the second section, and the third section are concentric.
