Abstract

Systems and methods for treating internal tissue defects, such as septal defects, with clip-based devices are provided. An exemplary clip-based device includes a tubular body having at least a first and a second deflectable member coupled thereto. The first and second members are coupled on opposite ends of the tubular body and configured to deflect between an undeployed configuration and a deployed configuration. In the deployed configuration, each member extends outwardly away from the tubular body in a position configured to abut a tissue surface. The first and second members are preferably configured to maintain a tissue wall therebetween and at least partially close any opening in the tissue wall.

Claims

1. A treatment system for treating a septal defect, comprising:

an implantable device, comprising an elongate body portion having a first end, a second end, and a variable length section located therebetween, the implantable device further comprising a first arm-like member coupled with the first end and a second arm-like member coupled with the second end, the arm-like members being configured to move from a stressed, undeployed configuration to an unstressed, deployed configuration, wherein the implantable device is configured to at least partially close a septal defect in a septal wall when the first and second arm-like members are in the deployed configuration; and

a delivery device configured to hold the undeployed arm-like members in a stressed condition prior to delivery of the implantable device, the delivery device comprising an elongate, flexible, needle-like member configured to pierce at least a portion of the septal wall.
