Abstract

A system for breast augmentation includes a plurality of microballoons. An injector can be provided for injecting microballoons into a breast through an incision in the breast. The microballoons can have a first dimension when in the injector and a second, larger dimension when in the breast. An injector and tissue dissector are also disclosed. A method for performing breast augmentation surgery and microballoons for use in the method are also disclosed.

Claims

1. A method of performing breast augmentation surgery, comprising the steps of:

making an incision;

inserting a tissue dissector through the incision and making a subcutaneous pocket with said tissue dissector;

providing a compressed microballoon with a microballoon injector, said injector for holding said microballoon in said compressed condition and for releasing said microballoon from said injector when said microballoon injector is inserted into said subcutaneous pocket;

inserting said microballoon injector through said incision and releasing said microballoon into said subcutaneous pocket without a carrier solution, said microballoon having a first dimension when held by said injector and a second, larger dimension when in said subcutaneous pocket, said second dimension being at least about 3 mm;

repeating said releasing step until a plurality of said microballoons have been released into said subcutaneous pocket, at least a portion of said balloons being in direct contact with tissue forming said subcutaneous pocket.

2. The method of claim 1, wherein said injector comprises a compression chamber with an open end, said compression chamber for holding said microballoon in said first, compressed dimension, and said releasing step comprising forcing said microballoon from said compression chamber through said open end and into said subcutaneous pocket.

3. The method of claim 2, wherein said providing step further comprises the step of compressing said microballoon into said injector by forcing said microballoon into said compression chamber, said compression chamber having an open interior with an interior dimension substantially the same as said first dimension, whereby said microballoon will assume said first dimension when forced into said compression chamber.

5. The method of claim 1, wherein said microballoons comprise a flexible, substantially spherical shell defining an open interior, said open interior being filled with a filling material.

6. The method of claim 1, wherein said microballoons have an uncompressed diameter between about 1 mm and about 50 mm.

8. The method of claim 1, wherein said subcutaneous pocket is formed under a breast.

4. A method of performing breast augmentation surgery, comprising the steps of:

making an incision;

inserting a tissue dissector through the incision and making a subcutaneous pocket with said tissue dissector;

providing a compressed microballoon with a microballoon injector, said injector for holding said microballoon in said compressed condition and for releasing said microballoon from said injector when said microballoon injector is inserted into said subcutaneous pocket, said microballoon having a first dimension when held by said injector and a second, larger dimension when in said subcutaneous pocket, said second dimension being at least about 3 mm, said injector comprising a compression chamber with an open end, said compression chamber for holding said microballoon in said first, compressed dimension, and said releasing comprising forcing said microballoon from said compression chamber through said open end and into said subcutaneous pocket, said microballoon being compressed into said injector by forcing said microballoon into said compression chamber, said compression chamber having an open interior with an interior dimension substantially the same as said first dimension, whereby said microballoon will assume said first dimension when forced into said compression chamber, said compressing step comprising the step of applying a vacuum to said compression chamber, whereby said microballoon will be drawn into said compression chamber and compressed to said first dimension;

inserting said microballoon injector through said incision and releasing said microballoon into said subcutaneous pocket without a carrier solution, and,

repeating said releasing step until a plurality of said microballoons have been released into said subcutaneous pocket.

9. The method of claim 4, wherein said subcutaneous pocket is formed under a breast.

7. A method for performing breast augmentation surgery, comprising the steps of:

providing a plurality of microballoons; and

placing said plurality of microballoons into a subcutaneous pocket under the breast without a carrier solution, at least a portion of said microballoons being in direct contact with tissue forming said subcutaneous pocket, said microballoons being at least about 3 mm in diameter.

10. The method of claim 7, wherein said subcutaneous pocket is formed under a breast.
