Abstract
Systems and methods for cutting tissue using a transcatheter approach are disclosed. In some examples, the systems and methods are implemented as part of a delivery system that includes an implant with a support structure and a cutting element coupled to the support structure, such that the cutting element configured to cut tissue.
Claims21
A delivery system comprising:
- a delivery device;
- an implant having a support structure, the implant being releasably coupled to the delivery device;
- and
- a tissue cutting system coupled to the delivery device and the implant, the tissue cutting system including a cutting element comprising a wire formed of a conductive material electrically connected to a current source and configured to cut tissue, wherein the wire comprises a first portion and a second portion extending from the first portion,
- wherein the first portion of the wire extends through a lumen of the delivery device and the implant and outwardly from a distal tip portion of the delivery device in a distal direction, and
- wherein the second portion of the wire extends from a distal end of the first portion of the wire in a proximal direction alongside the delivery device and the implant and then back into the delivery device at a location proximal the distal tip portion of the delivery device.
3 more elements
A method of delivering an implant to a treatment site, the method comprising:
- positioning the implant at the treatment site with a delivery device;
- and
- cutting tissue at the treatment site with a cutting element that is coupled to the delivery device and the implant, wherein the cutting element comprises a first portion and a second portion extending from the first portion,
- wherein the first portion of the cutting element extends through a lumen of the delivery device and the implant and then distally from an opening in a distal tip portion of the delivery device, and
- wherein the second portion of the cutting element curves from a distal end of the first portion of the cutting element in a proximal direction alongside the delivery device and the implant and back into the delivery device.
