The patch is wrapped around the mechanism and is forced radially outward into contact with and adhered to a target portion of tissue when the mechanism is longitudinally compressed and the bowing members are radially expanded. The mechanism is to radially retract after the patch has been adhered to the portion, from a deployed configuration to the insertion configuration to separate the patch from the mechanism leaving the patch in a desired position adhered to the portion.

Abstract

A scope adapter system (100) includes an adapter body (102) coupled to a handle of a scope device, a rigid shaft (110), and a mounting mechanism (104) removably coupled to the shaft. The shaft includes a shaft lumen which is sized and shaped to slidably receive a flexible elongated member of the device. A distal end of the lumen is sized so that, when a distal end of the member is received therein, the distal end of the member is snugly held so that an aim of the shaft aims the distal end of the member. The mechanism mounts a proximal end of the shaft to the body so that, when the body is coupled to the handle, the mechanism is mounted on the body and coupled to the shaft and the member is inserted into the lumen so that movement of the handle effects corresponding movements of the distal end of the member.

Abstract

Devices, systems, and methods for combining and/or delivering an injectable material to a patient. The injectable material may be formed of two or more reactive components delivered in separate chambers. Various features are provided to reduce human error in combining the reactive components in the appropriate sequence to form the injectable material, generally at (e.g., immediately prior to) the time of delivery to a patient. The system includes a sleeve lock which facilitates coupling of a device having a first chamber containing a first component with a vial having a second chamber containing a second component to combine the first and second components. The combined first and second components are contained within the first chamber for delivery to a patient via an injection system, which may be fluidly coupled with the first chamber with the assistance of the sleeve lock.
