Abstract
Methods of repairing cartilage defects are provided. The cartilage defect is identified and shaped to prepare the cartilage defect for a localized therapy. The cartilage defect is isolated with an isolation device. The localized therapy is then delivered to the cartilage defect through the isolation device.
Claims30
A method of repairing a cartilage defect comprising:
- a. identifying the cartilage defect;
- b. contouring the cartilage defect to prepare the cartilage defect for a localized therapy;
- c. isolating the cartilage defect with a barrier device of an isolation device by deploying the barrier device out from within a syringe of the isolation device, the barrier device moves from a collapsed position to an expanded position as the barrier device is deployed;
- and
- d. providing the localized therapy to the cartilage defect with the isolation device.

A method of repairing a cartilage defect comprising:
- a. resecting the cartilage defect to expose an underlying bone;
- b. microfracturing the underlying bone to induce bleeding;
- c. introducing an isolation device having a barrier device onto the cartilage defect;
- d. deploying the barrier device and arranging the barrier device over the cartilage defect to isolate a region of the microfractured bone from an ambient fluid, the isolation device comprises a syringe configured to house the barrier device in a collapsed position, and deploying the barrier device from within a barrel of the syringe, the barrier device moves from the collapsed position to an expanded position as the barrier device is deployed;
- e. applying a positive pressure from the isolation device to aspirate and dry the isolated region;
- and
- f. providing a localized therapy with the isolation device to the isolated region.

A method of repairing a cartilage defect comprising:
- a. contouring the cartilage defect to expose an underlying bone;
- b. isolating a region of the underlying bone from an ambient fluid at the cartilage defect with an isolation device by deploying a barrier device out from within a syringe of the isolation device to move the barrier device from a collapsed position to an expanded position as the barrier device is deployed;
- c. providing a localized therapy by applying a negative pressure from the isolation device to draw a blood material from the underlying bone into the cartilage defect;
- and
- d. providing a localized therapy by delivering a therapeutic agent to the isolated region of the cartilage defect with the isolation device.

A method of repairing a focal cartilage defect comprising:
- a. contouring the cartilage defect to expose an underlying bone;
- b. isolating a region of the bone from an ambient fluid at the cartilage defect with an isolation device by deploying a barrier device out from within a syringe of the isolation device to move the barrier device from a collapsed position to an expanded position as the barrier device is deployed;
- c. providing a localized therapy by delivering a UV curable therapeutic agent to the isolated region with the isolation device;
- and
- d. curing the UV curable therapeutic agent while isolating the region with the isolation device.
