Abstract
A system according to the present invention helps to reduce consumption of food by a patient. In one aspect, the system includes a banding apparatus which may be applied to around part of a patient's stomach to reduce that part to a reduced diameter. Another aspect provides wrapping apparatus that may extend from the banding apparatus and around an upper pouch of the stomach to inhibit expansion of the upper pouch beyond a predetermined volume. The wrapping apparatus further may be anchored relative to part of the patient's body to mitigate diaphragmatic hernia.
Claims32
An implantable system to inhibit expansion of an anatomical object located within the system, comprising:
- an elongated body portion of a flexible, biocompatible material having longitudinally spaced apart ends and side edges extending between the ends thereof, a slot extending a length through part of the body portion substantially transverse to a long axis of the body portion that at least approximates a width of part of the body portion proximal one of the ends;
- and
- first and second elongated end portions, each extending longitudinally from a respective end of the body portion, each of the elongated end portions having a width that is less than the width of the part of the body portion from which it extends;
- whereby, upon insertion of one of the first and second ends into the slot and movement of the inserted end portion through the slot and securing the end portions relative to an intermediate portion of the system, a generally cylindrical member is formed that inhibits radial expansion of the system.
A system to limit expansion of at least part of a stomach, comprising:
- a pair of spaced apart and generally cylindrical end portions, a first of the end portion operative to circumscribe a part of the esophagus adjacent the stomach, the second end portion operative to circumscribe a part of the stomach so as to restrict the part of the stomach to a reduced diameter;
- and
- a generally cylindrical web of a flexible biocompatible material extending between and connecting the first and second end portions, the web being expandable from a first volume to a second volume, which is greater than the first volume.
A system to help reduce food consumption when applied to part of a patient's stomach, comprising:
- restriction means for, when applied around part of the patient's stomach, restricting the part of the stomach to a desired reduced diameter, the restriction means having elongated means extending from a central part thereof for securing the restriction means relative to itself to provide the desired reduced diameter.
A system to help reduce consumption of food in a patient, comprising:
- banding means for reducing part of a stomach of the patient to a desired diameter;
- and
- means for enclosing at least a substantial part of the patient's stomach extending from the banding means to a location adjacent an esophagus of the patient, the means for enclosing permitting expansion and contraction of the part of the patient's stomach between a first volume and a second volume, which is greater than the first volume.
An implantable system to inhibit expansion of an anatomical object located within the system, comprising:
- an elongated body portion of a flexible, biological tissue material having longitudinally spaced apart ends and side edges extending between the ends thereof, a slot extending a length through part of the body portion substantially transverse to a long axis of the body portion;
- and
- first and second elongated end portions, each extending longitudinally from a respective end of the body portion, at least one of the elongated end portions being dimensioned and configured to facilitate insertion thereof into the slot;
- whereby, upon insertion of one of the first and second ends into the slot and movement of the inserted end portion through the slot and securing the end portions relative to an intermediate portion of the system, a generally cylindrical member is formed that inhibits radial expansion of the system.
