Devices and methods for treatment of obesity
First Claim
1. An implantable device for treatment of a patient to assist weight loss, said device comprising:
- a fillable member configured to be positioned exteriorly of the stomach in an abdominal cavity of the patient, said fillable member configured to be filled after placement of said device in the abdominal cavity, wherein said device, with said fillable member in a filled configuration, has a buoyancy characteristic comprising a density of about 900 kg/m3 to about 1100 kg/m3.

Abstract
Implantable devices, methods of implantation and tools for performing the implantations. A device includes a volume occupying member having a working configuration such that, when the device is implanted into the abdominal cavity of the patient, the device performs at least one of: prevention of expansion of the stomach of the patient into a space occupied by the volume occupying member in the abdominal cavity; and compression of a portion of the stomach. A device is configured to have substantially neutral buoyancy or a slightly positive buoyancy when implanted in the abdominal cavity external of the stomach. An attachment member is connected to the volume occupying member, and at least a portion of the attachment member is configured to encourage tissue ingrowth from at least one internal abdominal structure when held in contact therewith.

- 2. The device of claim 2, further comprising a buoyancy member exhibiting substantially uniform density throughout, wherein said density of said buoyancy member is less than a density of said fillable member when said fillable member is filled with a liquid, such that, when said buoyancy member is combined with said fillable member in said filled configuration, said density of said device is less than said density of said fillable member when filled with a liquid and not combined with said buoyancy member.

26. A method of treating a patient, said method comprising the steps of:
-
taking at least one internal measurement in an abdominal space of the patient; and selecting an appropriately sized device for implantation into the abdominal cavity of the patient, based on the internal measurements taken. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50)
