Anchor deployment devices and related methods

摘要

Described here are devices, methods, and kits for the deployment of tissue anchors. In some variations, the devices may comprise a shaft defining a lumen for housing at least one anchor therein and a mechanism for deploying the anchor distally from the lumen. In certain variations, the devices may comprise one or more stop elements. For example, a device may comprise a stop element that limits the advancement of the device through an opening in a wall portion or at the distal end of another device.

1. A catheter comprising:
a tubular elongated member having a proximal end, a distal end, a side portion therebetween and a lumen therethrough, wherein the tubular elongated member comprises a preformed shape having a first region defining a first plane and a second region defining a second plane at an angle with respect to the first plane; an elongated wire extending from the side portion, wherein a bend in the elongated wire signals to an operator when to stop advancing the tubular elongate member; and a stop element comprising a tubular member disposed within the lumen of the tubular elongated member.
