Abstract: A device for treating hemorrhoids includes a housing sized and shaped for insertion to a target site within a rectum. The device also includes an inner member received within the housing such that the member may move longitudinally relative to the housing. In addition, the device includes a ligating mechanism at a distal end of the member which includes grasping arms movable between a receiving configuration in which distal ends of the arms are separated from one another and a grasping configuration in which the distal ends are drawn together to grasp tissue. The mechanism includes a ligating band received around the arms that is movable distally off of the arms to constrict around tissue grasped by the arms.

Abstract: A device for treating tissue includes a clip including clip arms and a coupler. Each of the clip arms extends from a proximal end to a distal end. Proximal ends of the clip arms are slidably received within a channel of a capsule. A proximal end of the capsule includes openings extending through a wall. The coupler is mounted over the proximal end of the capsule via deployment arms including engaging features extending laterally inward from an interior surface thereof to engage the openings of the capsule. The coupler includes retention arms configured to engage a corresponding portion of an applicator. When a pre-determined compressive force is applied to the coupler, the deployment arms are proximally slidable along the corresponding portion of the applicator to deflect the deployment arms out of engagement with the capsule so that the coupler is separable from the capsule.

Abstract: Compositions including a plurality of particles that may be prepared from a chitosan salt and methods for preparing the same. The plurality of particles may have an average diameter ranging from about 100 μm to about 750 μm, such as from about 150 μm to about 500 μm; a steepness value ranging from about 30 to about 90; and an average aspect ratio greater than 0.6. The plurality of particles may be substantially spherical in shape, for example. Methods of preparation include electrospraying a chitosan salt solution through a needle.
