Abstract

A medical device may include a conduit and a porous body coupled to a distal end of the conduit. The medical device may have a first loop extending proximally from a proximal end of the porous body. The medical device may have a second loop extending distally from a distal end of the porous body.

First claim

We claim:

1 . A medical device, comprising:
a conduit; a porous body coupled to a distal end of the conduit; a first loop extending proximally from a proximal end of the porous body; and a second loop extending distally from a distal end of the porous body.

2 . The medical device of claim 1 , wherein in a first configuration, the porous body has a first length and a first width, wherein in a second configuration, the porous body has a second length and a second width, wherein the second length is greater than the first length, and wherein the second width is less than the first width.

3 . The medical device of claim 2 , wherein, to transition the porous body from the first configuration to the second configuration, the first loop is pulled proximally.

4 . The medical device of claim 1 , wherein the first loop defines a proximal end of an elongate body, wherein the second loop defines a distal end of the elongate body, and wherein a center portion extends between each of the first loop and the second loop.

5 . The medical device of claim 4 , wherein each of the first loop and the second loop is integrally formed with the center portion.

6 . The medical device of claim 4 , wherein the center portion extends through at least a portion of the porous body.

7 . The medical device of claim 4 , wherein the center portion includes a plurality of turns.

8 . The medical device of claim 7 , wherein the plurality of turns extend circumferentially around at least a portion of the porous body.

9 . The medical device of claim 1 , wherein a netting extends between the first loop and the second loop, wherein the netting extends circumferentially around at least a portion of the porous body.

10 . The medical device of claim 1 , wherein a longitudinal axis extends through the conduit and the porous body.

11 . The medical device of claim 10 , wherein the second loop is offset from the longitudinal axis.

12 . The medical device of claim 1 , wherein at least one of the first loop or the second loop is comprised of at least one of a thread, a wire, or a cable.

13 . The medical device of claim 1 , wherein at least one of the first loop or the second loop is a suture.

14 . The medical device of claim 1 , wherein the conduit includes a coupler, wherein the coupler is configured to removably couple the conduit and the porous body.

15 . The medical device of claim 1 , wherein the conduit is configured to be coupled to a vacuum source, wherein the vacuum source is configured to provide a negative pressure to the porous body.

16 . A medical system, comprising:
a delivery device including a working channel extending therethrough; a first medical device, wherein the first medical device is movably disposed within the working channel of the delivery device; and a second medical device, wherein the second medical device comprises:
a conduit,
a porous body coupled to a distal end of the conduit, and
an elongate body, wherein a proximal end of the elongate body includes a first loop, wherein a distal end of the elongate body includes a second loop.

17 . The medical system of claim 16 , wherein a center portion of the elongate body includes a plurality of turns, wherein the plurality of turns extend circumferentially around at least a portion of the porous body,
wherein in a first configuration, the porous body has a first length and a first width, wherein in a second configuration, the porous body has a second length and a second width, wherein the second length is greater than the first length, wherein the second width is less than the first width, and wherein, to transition the porous body from the first configuration to the second configuration, the first loop is pulled proximally.

18 . The medical system of claim 16 , wherein the second medical device is movably disposed adjacent to the delivery device.

19 . A method for performing a medical procedure, the method comprising:
inserting a medical device into a lumen of a patient, the medical device including:
a porous body coupled to a distal end of a conduit,
a proximal loop extending proximally from the porous body, and
a distal loop extending distally from the porous body;
using the distal loop to move the medical device into a wound cavity, wherein, upon using the distal loop to move the medical device into the wound cavity, the distal loop is on a first side of a wall defining the lumen, the porous body extends through at least a portion of the wall defining the lumen, and the proximal loop is on a second side of the wall defining the lumen; applying a vacuum pressure to the porous body via the conduit; and pulling the proximal loop in a proximal direction to remove the medical device from the wound cavity.

20 . The method of claim 19 , wherein, upon pulling the proximal loop in the proximal direction, a length of the porous body increases and a width of the porous body decreases.
