Abstract
A material-fastening device and related fastener and methods for use, and more particularly, a device with segments of the fastener capable of being independently exposed from a holding mechanism and independently attached to or placed in proximity to the material.
Claims20
A tissue treating device comprising:
- a fastener having a first element, a second element, and a connection portion connecting the first element to the second element;
- a moving mechanism having a biasing element connected to the first and second elements, the biasing element configured to move the second element relative to the first element;
- and
- an extension device configured to releasably hold the fastener via the biasing element, a distal end of the extension device configured to expose the first element independently of exposing the second element such that the first element is disposed at an angle relative to a longitudinal axis of the extension device when exposed, the distal end further configured to expose the second element, such that the second element, when exposed, is moved by the biasing element toward a deployed position in which, if no tissue is received between the first and second elements, the first and second elements extend from the connection portion at the angle substantially parallel to one another.

A tissue gripping device comprising:
- an elongate member including a holding chamber formed at a distal end thereof;
- a first tissue fastener received in the holding chamber, the first tissue fastener including first and second elements coupled to one another via a connection part;
- a longitudinal element extending through the elongate member to a proximal end thereof, the longitudinal element being operable to move the first tissue fastener distally from an insertion configuration to a first stage deployment position in which the first element is exposed from the holding chamber while the second element remains received therewithin and a second deployment position in which the second element of the first tissue fastener is exposed from the holding chamber;
- and
- a first biasing arrangement biasing the first and second elements toward one another to grip tissue positioned therebetween, the first biasing arrangement operating so that, when the first element is exposed from the holding chamber and the second element is retained therein, the first element extends away from the holding chamber at a first angle relative to a longitudinal axis of the holding chamber and operating when the second element is exposed from the holding chamber so that, if no tissue is received between the first and second elements, both the first and second elements extend from the connection part at the first angle relative to the longitudinal axis of the holding chamber substantially parallel to one another, the longitudinal element being releasably coupled to the first tissue fastener via the first biasing arrangement.
