Implant for Treating Gastroesophagael Reflux Disease
An implant wrapped around the gastroesophageal junction to treat gastroesophageal reflux disease is provided. The implant is positioned around the junction by navigating the implant partly around the junction by a first needle and pulling the remainder of the distance with a second needle. A suture connector can be affixed to the implant with a suture, which can be used to pull the implant into place around the gastroesophageal junction.
1 . An implant system to compress a body lumen to treat gastroesophageal reflux disease in a patient, comprising:
an introducer device having a handle portion and an elongated needle portion, the elongated needle portion having a distal tip portion;
an elongated implant including a first end portion and a second end portion; and
a connector element having an engagement feature adapted to receive at least the distal tip portion such that the introducer device is adapted to direct the first end portion of the elongated implant around a portion of an esophageal junction of the patient to facilitate compression of the esophageal junction.
2 . The system of claim 1 , further including a second introducer device having a handle portion and an elongated needle portion, with the elongated needle portion of the second introducer device having a distal tip portion adapted to engage the connector element to further direct the elongated implant around the esophageal junction of the patient.
3 . The system of claim 2 , wherein the elongated needle portion of the second introducer device is at least partly curved.
4 . The system of claim 1 , wherein the elongated needle portion of the introducer device is at least partly curved.
5 . The system of claim 1 , wherein the elongated implant is at least partly constructed of a porous mesh material.
6 . The system of claim 1 , wherein the engagement feature includes a channel adapted to receive the distal tip portion of the introducer needle device.
7 . The system of claim 1 , wherein at least the first end portion of the elongated implant includes a fixation element adapted to secure the first end portion of the elongated implant and the second end portion of the elongated implant such that the elongated implant is deployed to securely wrap around the esophageal junction.
8 . The system of claim 1 , wherein the connector element is provided at the first end portion of the elongated implant.
9 . The system of claim 1 , further including at least one filament member extending between and connecting the connector element with the first end portion of the elongated implant.
10 . The system of claim 9 , wherein the at least one filament member is at least one suture.
11 . An implant system to treat gastroesophageal reflux disease in a patient, comprising:
a first needle device having a distal tip portion;
a second needle device having a distal tip portion;
an elongated implant including a first end portion and a second end portion; and
a connector element having an engagement feature adapted to receive at least the distal tip portion of the first needle device such that the first needle device is adapted to direct the first end portion of the elongated implant around a portion of an esophageal junction of the patient and the second needle device is adapted to pull the first end portion of the elongated implant the remaining way around the esophageal junction to facilitate compression of the esophageal junction.
12 . The system of claim 11 , wherein at least the first needle device includes a handle portion having one or more actuators to facilitate engagement between the distal tip portion of the first needle device and the connector element.
13 . The system of claim 11 , wherein at least a portion of at least one of the first and second needle devices is curved.
14 . The system of claim 11 , wherein the elongated implant is at least partly constructed of a porous mesh material.
15 . The system of claim 11 , wherein the engagement feature includes a channel adapted to receive the distal tip portion of the first needle device.
16 . The system of claim 11 , wherein at least the first end portion of the elongated implant includes a fixation element adapted to secure the first end portion of the elongated implant and the second end portion of the elongated implant such that the elongated implant is securely deployed around a portion of the esophageal junction.
17 . The system of claim 16 , wherein the fixation element is a grommet element.
18 . The system of claim 11 , wherein the connector element is provided at the first end portion of the elongated implant.
19 . The system of claim 11 , further including at least one suture member extending between and connecting the connector element with the first end portion of the elongated implant.
20 . The system of claim 11 , further including a sheath at least partially shrouding the elongated implant during deployment.
