AI Technical Summary

Technical Problem

Minimally invasive medical procedures face challenges in accurately positioning and orienting delivery devices due to the treatment site's inaccessibility, making it difficult to adjust the position of device parts relative to the implantation site without additional locating means.

Method used

A positioning device with a distal portion that can be expanded and anchored at the treatment site, allowing for precise positioning and orientation of the delivery device by engaging with the defect, and comprising mechanisms like balloons or shape memory materials to provide reaction forces for implant placement.

Benefits of technology

Enables easy and precise positioning of medical implants by anchoring the delivery device, eliminating the need for additional locating means and facilitating implant placement through the defect site.

Abstract

To provide a positioning device comprising a distal part that is adapted to be delivered through a defect, preferably an opening in a ventricular or atrial septum.SOLUTION: The invention relates to a positioning device 1 comprising a distal part 8 that is adapted to be delivered through a defect, preferably an opening in a ventricular or atrial septum. It comprises a mechanism to selectively expand the distal part, such that, before expansion, it can be deployed through the defect, and upon expansion, is mechanically prevented from being retracted through the same defect. Thus, the positioning device is temporarily engaged at the defect site.SELECTED DRAWING: Figure 2
