Implantable restriction system tension release mechanism
First Claim
1. An apparatus for regulating the functioning of a patient'"'"'s organ or duct, comprising:
- an elongated member having a first end and a second end;
a fastener disposed on the first end of the elongated member, the fastener configured to engage the second end of the elongated member so that the elongated member forms a loop around the organ or duct;
a tension element disposed for movement within the elongated member and in engagement with the elongated member in a manner allowing for the tension element to be released from engagement with the elongated member;
a drive element associated with and engaging the tension element for causing the tension element to control the tension applied by the elongated member against a patient'"'"'s body organ or duct; and
a tension release mechanism associated with the tension element selectively releasing the tension element from engagement with the elongated member; and
wherein the tension element includes a free end engaged with the drive element and a fixed end secured to the elongated member, and the tension release mechanism includes a release pin extending through the elongated member and in engagement with the fixed end of the tension element.

Abstract
An apparatus for regulating the functioning of a patient'"'"'s organ or duct includes an elongated member having a first end and a second end. A fastener is disposed on the first end of the elongated member. The fastener is configured to engage the second end of the elongated member so that the elongated member forms a loop around the organ or duct. A tension element is disposed for movement within the elongated member. A drive element is associated with and engages the tension element for causing the tension element to control the tension applied by the elongated member against a patient'"'"'s body organ or duct. A tension release mechanism is associated with the tension element.
