US 12,661,123 B2 · Devices, treatments and methods to restore tissue elastic recoil

Abstract

Pulmonary treatment devices, systems and methods of use are provided which take into account the vast tissue damage of advanced COPD sufferers and provide treatments designed specifically to treat the particularly compromised lung tissues that are present in these patients. These treatments reduce trapped air volume, tension lung tissue and enhance lung elastic recoil. In particular, a variety of embodiments of pulmonary treatment devices are provided. The devices are comprised of a shape memory material wherein the devices are able to be expanded under tension, and then are able to recoil back toward an original relaxed or resting shape as the devices are deployed into the tissue. This action causes the pulmonary treatment devices to corkscrew into damaged tissue, becoming sufficiently entwined to allow pulling of the tissue by retraction of the device. This in turn re-tensions the lung causing lung volume reduction.

Claims36

Dependent claims

A method of causing a volume of at least one lobe of a lung to be reduced, comprising:

advancing a shaft of a delivery catheter into a lung passageway so that a distal tip of the shaft is positioned near damaged lung tissue;
deploying a portion of a pulmonary treatment device from the distal tip of the shaft into the damaged lung tissue so that the portion of the pulmonary treatment device gathers the damaged lung tissue as it deploys, wherein the portion of the pulmonary treatment device comprises at least one tissue gathering element having a plurality of loops and wherein deploying the portion of the pulmonary treatment device comprises releasing the at least one tissue gathering element from a constrained position so that the plurality of loops curves through the damaged lung tissue, wherein the plurality of loops comprises a coil and wherein releasing the at least one tissue gathering element from the constrained position causes the coil to corkscrew through the damaged lung tissue;
pulling the pulmonary treatment device;
and
anchoring the pulmonary treatment device so as to reduce the volume of the at least one lobe of the lung.

2 more elements

A method of causing a volume of at least one lobe of a lung to be reduced, comprising:

advancing a shaft of a delivery catheter into a lung passageway so that a distal tip of the shaft is positioned near damaged lung tissue;
mating a delivery accessory containing the pulmonary treatment device to a proximal end of the catheter prior to deploying a portion of the pulmonary treatment device from the distal tip of the shaft into the damaged lung tissue;
deploying the portion of a pulmonary treatment device from the distal tip of the shaft into the damaged lung tissue so that the portion of the pulmonary treatment device gathers the damaged lung tissue as it deploys;
pulling the pulmonary treatment device;
and
anchoring the pulmonary treatment device so as to reduce the volume of the at least one lobe of the lung.
