Treatment of cavities in a human body
First Claim
1. A method for treating a cavity in a human body using a barrier device having a collapsed configuration and an expanded configuration, the method comprising:
- deploying the barrier device from a delivery tube, using a pushing element slidably disposed within a lumen of the delivery tube, the barrier device moving from the collapsed configuration to the expanded configuration upon being deployed; and
conformingly contacting the barrier device with tissue surrounding the cavity, using a plurality of barrier-deployment elements coupled at respective distal ends thereof to the barrier device and to the pushing element,the cavity including at least one defect selected from the group consisting of;
a chondral defect, and an osteochondral defect,wherein a first one of the barrier-deployment elements includes a spring, including;
a first spring-arm that is pivotably coupled to the pushing element at a proximal end of the first spring-arm; and
a second spring-arm that is pivotably coupled to the pushing element at a proximal end of the second spring-arm, wherein the proximal end of the second spring-arm is more longitudinally moveable with respect to the pushing element than is the proximal end of the first spring-arm.

Abstract
Apparatus and methods are described, including apparatus for treating a cavity in a human body, the apparatus including a delivery tube. A bather device has a collapsed configuration and an expanded configuration, the barrier device moving from the collapsed configuration to the expanded configuration upon being deployed from the delivery tube. A pushing element, slidably disposed within a lumen of the delivery tube, is configured to deploy the barrier device from the delivery tube by pushing the bather device. One or more bather-deployment elements are coupled to the barrier device and to the pushing element, the bather-deployment elements being configured to conformingly contact the barrier device with tissue surrounding the cavity. Other applications are also described.

18. A method for treating a cavity in a human body using a barrier device having a collapsed configuration and an expanded configuration, the method comprising:
-
deploying the barrier device from a delivery tube, using a pushing element slidably disposed within a lumen of the delivery tube, the barrier device moving from the collapsed configuration to the expanded configuration upon being deployed; and conformingly contacting the barrier device with tissue surrounding the cavity, using a plurality of barrier-deployment elements coupled at respective distal ends thereof to the barrier device and to the pushing element, the cavity including a defect in bone tissue, wherein a first one of the barrier-deployment elements includes a spring, including; a first spring-arm that is pivotably coupled to the pushing element at a proximal end of the first spring-arm; and a second spring-arm that is pivotably coupled to the pushing element at a proximal end of the second spring-arm, wherein the proximal end of the second spring-arm is more longitudinally moveable with respect to the pushing element than is the proximal end of the first spring-arm.

19. A method for treating a cavity in a human body using a barrier device having a collapsed configuration and an expanded configuration, the method comprising:
-
deploying the barrier device from a delivery tube, using a pushing element slidably disposed within a lumen of the delivery tube, the barrier device moving from the collapsed configuration to the expanded configuration upon being deployed; and conformingly contacting the barrier device with tissue surrounding the cavity, using a plurality of barrier-deployment elements coupled at respective distal ends thereof to the barrier device and to the pushing element, the cavity including a defect in periodontal tissue, wherein a first one of the barrier-deployment elements includes a spring, including; a first spring-arm that is pivotably coupled to the pushing element at a proximal end of the first spring-arm; and a second spring-arm that is pivotably coupled to the pushing element at a proximal end of the second spring-arm, wherein the proximal end of the second spring-arm is more longitudinally moveable with respect to the pushing element than is the proximal end of the first spring-arm.
