Abstract
A percutaneous delivery system with a high degree of flexibility is provided. In one embodiment, the system includes a catheter having a portion comprising multiple segments, linked in series by at least one connecting wire. Joints between the multiple segments provide a high degree of flexibility. In some embodiments, only a distal portion is made up of segments. In other embodiments, the whole length of the catheter is made up of segments. Manipulation of the at least one connecting wire enables manipulation of the segments to flex a portion of the catheter. In one aspect, the invention provides a delivery system that reduces the impact of the delivery system on the final release position of the implant delivered. The delivery system can be used to deploy and/or retrieve implantable medical devices, for example, patent foramen ovale (PFO) occluder.
