Abstract
The present invention generally provides improved medical devices, systems, and methods, particularly for treating one or both lungs of a patient with an implant, such as a coil, having a strength tuned to a patient's tissue treatment region. More particularly, embodiments of the present invention include implant assemblies and systems for treating a lung of a patient with chronic obstructive pulmonary disease. The implant assemblies may comprise an elongate body comprising an alloy that may be characterized by its austenite final tuning. The implant may include multiple portions that may be of different austenite final tunings.
Claims21
An implant assembly for treating a lung of a patient with chronic obstructive pulmonary disease, the implant assembly comprising:
- an elongate body having a constrained delivery configuration and a deployed bent configuration adapted to compress a lung tissue volume, at least a portion of the elongate body comprising at least one alloy having a high austenite final tuning, wherein the high austenite final tuning is characterized by an austenite final temperature that is greater than or equal to about 30 degrees Celsius.
An implant assembly for treating a lung of a patient with chronic obstructive pulmonary disease, the implant assembly comprising:
- an elongate body having proximal and distal portions and an intermediate portion therebetween, wherein the elongate body has a constrained delivery configuration and a deployed configuration adapted to compress a lung tissue volume, wherein:
- at least one of the proximal, distal, and intermediate portions comprise an alloy having a first austenite final tuning, and
- at least one of the proximate, distal, and intermediate portions comprise an alloy having a second austenite final tuning different from the first austenite final tuning.
An implant system for treating a lung of a patient with chronic obstructive pulmonary disease, the implant system comprising:
- an elongate implant support having a proximal end and a distal end configured for advancement into the lung of a patient in alignment with a first region of a patient;
- and
- a plurality of alternatively selectable implants, each implant having:
- an elongate implant body deployable from an insertion configuration to a deployed configuration within the lung,
- the elongate body in the insertion configuration advanceable distally within the lung by the implant support, and
- the elongate body, when deployed from the insertion configuration to the deployed configuration in the lung, configured to locally compress an associated volume of lung tissue by applying an associated compressive load;
- wherein the elongate bodies of the plurality of implants have differing strengths at body temperature so that the compressive loads are variably selectable by selecting and deploying a desired implant having a desired strength.
