MINIMALLY INVASIVE SURGICAL TECHNIQUES

摘要

Apparatus and methods are provided for use with a hole closure device that is configured to be deployed by expanding inside a subject's body. An insertion device includes an outer tube and an inner pushing element. The outer tube constrains the hole closure device from expanding, during insertion of the hole closure device into the subject's body. The pushing element causes at least a portion of the hole closure device to self expand by pushing the portion out of a distal end of the outer tube, by the pushing element being advanced distally with respect to the outer tube. A safety element is couplable to the pushing element and is configured to prevent the hole closure device from expanding, by preventing distal advancement of the pushing element with respect to the outer tube, when the safety element is coupled to the pushing element. Other applications are also described.

1. Apparatus, for use with a self-expandable hole closure device that is configured to be deployed by self-expanding inside a body of a subject, the apparatus comprising:
an insertion device that comprises an outer tube and an inner pushing element,
the outer tube being configured to constrain the self-expandable hole closure device from expanding by the self-expandable hole closure device being disposed inside the outer tube, during insertion of the self-expandable hole closure device into the subject's body,the pushing element being configured to cause at least a portion of the self-expandable hole closure device to self expand by pushing the portion of the self-expandable hole closure device out of a distal end of the outer tube, by the pushing element being advanced distally with respect to the outer tube; and a safety element that is couplable to the pushing element and that is configured to prevent the self-expandable hole closure device from expanding, by preventing distal advancement of the pushing element with respect to the outer tube, when the safety element is coupled to the pushing element.
