Devices and methods for gastrointestinal bypass
Delivery devices are described. In one embodiment, a delivery device includes a catheter and a sealing pad coupled to an outer surface of the catheter. The delivery device may further include a recess formed in an outer surface of the catheter. The sealing pad may be coupled in the recess. Methods for delivering a tubular device are described. In one embodiment, a method may include inserting a distal end of a catheter into a lumen of a tubular device. The catheter may include a sealing pad coupled to an outer surface of the catheter. The method also includes positioning the sealing pad inside a drawstring coupled circumferentially to the tubular device, and cinching the drawstring around the catheter at the sealing pad to couple the tubular device to the catheter.
1. A delivery device for delivering a gastrointestinal bypass device, the gastrointestinal bypass device having a drawstring coupled at least partially around the gastrointestinal bypass device, the delivery device comprising:
a catheter configured to be at least partially inserted into the gastrointestinal bypass device; and
a sealing pad coupled around an outer surface of the catheter, the sealing pad configured to be cinched inside the drawstring to form a seal between the catheter and the gastrointestinal bypass device.
2. The delivery device of claim 1 , further comprising:
a recess formed around the catheter in the outer surface of the catheter.
3. The delivery device of claim 2 , wherein the sealing pad is at least partially coupled in the recess.
4. The delivery device of claim 2 , wherein a depth of the recess is substantially the same as a thickness of the sealing pad.
5. The delivery device of claim 1 , further comprising:
an anchoring cavity formed in the catheter, the anchoring cavity in communication with a primary lumen of the catheter.
6. The delivery device of claim 5 , wherein the anchoring cavity is distal to the sealing pad.
7. The delivery device of claim 5 , further comprising:
a secondary lumen formed in the catheter, the secondary lumen having a distal portion positioned at a proximal side of the anchoring cavity.
8. The delivery device of claim 7 , wherein the distal portion of the secondary lumen is angled from a longitudinal axis of the catheter at an angle of 0 degrees to 10 degrees.
9. The delivery device of claim 7 , further comprising:
a delivery needle slidably disposed in the secondary lumen, the delivery needle configured to be advanced out of and withdrawn into the secondary lumen.
10. The delivery device of claim 9 , wherein the delivery needle includes a slot formed in a distal portion of the delivery needle.
11. The delivery device of claim 1 , wherein the sealing pad includes a soft material.
12. The delivery device of claim 1 , wherein the sealing pad includes silicone.
13. A delivery device for delivering a gastrointestinal bypass device, the gastrointestinal bypass device having a drawstring coupled at least partially around the gastrointestinal bypass device, the delivery device comprising:
a catheter configured to be at least partially inserted into the gastrointestinal bypass device; and
a sealing means around an outer surface of the catheter, the sealing means configured to be cinched inside the drawstring to form a seal between the catheter and the gastrointestinal bypass device.
