Abstract

A system for treating a septal defect having a suture-like implantable treatment apparatus and devices for delivering the implantable treatment apparatus and methods for treating a septal defect are provided. The suture-like apparatus is preferably implantable through a septal wall or portion thereof. The treatment system can include a flexible elongate body member, a delivery device configured to deliver the suture-like apparatus, a stabilization device configured to stabilize the delivery device and a positioning device configured to position the delivery device in a desired location. The suture-like device can include a suture body coupled with one or more lock devices or anchor devices.

Independent Claims | See all claims (74)

  1. 1. In a method of closing a patent foramen ovale in a septal wall of the heart, the improvement comprising: advancing an elongate flexible outer tubular member having an inner lumen through the vasculature of a patient and into proximity with the patient's heart; advancing the outer tubular member into the patient's heart and into proximity with the septum secundum of a patent foramen ovale, the outer tubular member housing in its inner lumen a first and a second inner elongate tubular member in a first constrained configuration, each inner elongate tubular member having a lumen and a substantially sharp distal end and each inner tubular member having, respectively, a first and second suture body in its lumen each inner elongate tubular member further having a distal portion, a proximal portion, and a non-linear intermediate portion located therebetween, wherein a longitudinal axis of each distal portion is substantially parallel to a longitudinal axis of each proximal portion; advancing the first and second inner elongate tubular members distally out of the inner lumen of the outer tubular member such that the first and second inner elongate tubular members deflect from the first constrained configuration to a second expanded configuration wherein the distal portion of each of the inner elongate tubular members is spaced away from the other and the distal portions and sharp distal ends extend in a distal direction and transverse to the septum secundum prior to penetrating the septum secundum; advancing said first and second tubular members distally so that each of them penetrates the septum secundum and the septum primum; and deploying said first and second suture bodies from within the first and second inner elongate tubular members respectively.
  2. 67. In a medical system for closing a patent foramen ovale, the improvement comprising: an elongate flexible outer tubular member having a proximal and a distal end and having an inner lumen and configured for advancement through the vasculature of a patient; and a first and a second inner elongate tubular member housed in said outer tubular member, each inner elongate tubular member having a substantially sharp extending in a distal direction and configured to pierce septal tissue in a septal wall of the heart; wherein the first and second inner elongate tubular members are configured to be slidably housed within the inner lumen of the outer tubular member in a configuration such that the distal ends of the first and second inner elongate tubular members are in relative proximity to each other, and wherein the first and second inner elongate tubular members are configured to deflect, upon advancement from within the inner lumen, such that the distal ends of the first and second inner elongate tubular members are spaced a relatively greater distance from each other than when housed within the inner lumen, and wherein each inner elongate tubular member further has a distal portion, a proximal portion, and a non-linear intermediate portion located therebetween, wherein a longitudinal axis of each distal portion is substantially parallel to a longitudinal axis of each proximal portion.
