Abstract

The present invention provides devices and methods for attachment of an implanted device, such as an artificial stoma device, a gastrointestinal sleeve device or an attachment cuff, within a patient'"'"'s digestive tract for treatment of obesity. Special surgical fasteners provide a lasting and durable attachment to the gastrointestinal tissue without causing excessive pressure that could result in tissue erosion and detachment of the implanted device. Fastener delivery devices that facilitate peroral placement and deployment of fasteners and secondary devices are also provided. Also described are implantable devices and attachment means that avoid causing excessive pressure within the tissue by having compliance that is compatible with the gastrointestinal tissues where it is attached.

Claims

1. A gastrointestinal implant, comprising:

an elongate, tubular body, having a proximal end, a distal end, a length adapted to extend distally from gastroesophageal junction, and

a diameter less than the diameter of the gastrointestinal lumen;

an attachment ring about the proximal end of the elongate, tubular body; and

a plurality of tissue fasteners extending from the attachment ring, wherein each tissue fastener comprises;

an elongate member adapted to enter a tissue wall adjacent to the attachment ring; and

a transverse retention element joined to the elongate member for resisting movement of the elongate member.

2. The gastrointestinal implant of claim 1, wherein the transverse retention element has a circular configuration.

3. The gastrointestinal implant of claim 1, wherein the transverse retention element has a linear configuration.

4. A gastrointestinal implant, comprising:

an elongate, tubular body, having a proximal end, a distal end, a length of at least about 60 cm and a diameter less than about 4 cm;

an attachment ring about the proximal end of the elongate, tubular body; and

a plurality of tissue fasteners extending from the attachment ring, wherein each tissue fastener comprises;

an elongate member adapted to interface with a tissue wall adjacent to the attachment ring; and

a transverse retention element joined to the elongate member for resisting movement of the elongate member.

5. The gastrointestinal implant of claim 4, wherein the transverse retention element has a circular configuration.

6. The gastrointestinal implant of claim 4, wherein the transverse retention element has a linear configuration.
