Devices and methods for treatment of obesity
View Patent ↗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.
1. A method of treating a patient, said method comprising:
measuring at least one measurement of anatomy in an abdominal space internal to the rib cage of the patient with a measuring device; and
selecting an appropriately sized device, wherein the device comprises a single expandable member having different length and diameter dimensions and an attachment member attached thereon, said attachment member configured to be attached to an internal abdominal structure in the abdominal cavity and maintain the expandable member in abutment to the internal abdominal structure, said attachment member having a free end extending from the expandable member, for implantation into the abdominal cavity of the patient, based on the at least one internal measurement taken;
wherein said measuring at least one internal measurement includes measuring both Lateral and AP measurements.
2. The method of claim 1 , wherein said AP measurement is taken by measuring a distance from a posterior inside surface of a rib of the patient at a level of and through the center of the gastroesophageal junction to an anterior inside surface of the rib at the level of the gastroesophageal junction; and the Lateral measurement is taken from midline to a left lateral inside surface of the rib, through the center of the location of the gastroesophageal junction, at the level of the gastroesophageal junction.
3. A method of treating a patient, said method comprising:
measuring at least one measurement in an abdominal space internal to the rib cage of the patient with a measuring device; and
selecting a single appropriately sized device for implantation into the abdominal cavity of the patient, based on the at least one internal measurement;
wherein said measuring at least one internal measurement includes measuring at least a Lateral measurement and an AP measurement.
