Abstract

A tissue press for shaping or compressing a piece of tissue comprises first and second members movable relative to each other. A first forming element of a predetermined shape is selectively engageable on the first member. A second forming element of predetermined shape is selectively engageable on the second member. The first and second forming elements are positionable on opposite sides of the piece of tissue. The first and second members are relatively movable between a first spaced apart condition and a second condition in which the piece of tissue is held between the first and second forming elements. Means are preferably provided for monitoring and controlling the amount of pressure applied to the piece of tissue, in order to maintain the tissue in a viable living condition. Means may also be provided for draining off fluid from compressed tissue, so that the tissue can be implanted in a compressed state and imbibe fluid from the host site. A retainer, which may be expandable, can be used to maintain the tissue graft in a compressed condition.

Claims

1. A method of using human tissue, said method comprising the steps of removing the tissue from a human body, enclosing the tissue removed from the human body with a retainer, applying pressure against the tissue removed from the human body to shape the tissue removed from the human body to a desired configuration, and inserting the human tissue into a human body with the tissue in the retainer said method further including the step of conducting fluid from the human tissue during performance of said step of applying pressure against the tissue removed from the human body.

2. A method of using human tissue, said method comprising the steps of removing the tissue from a human body, enclosing the tissue removed from the human body with a retainer, applying pressure against the tissue removed from the human body to shape the tissue removed from the human body to a desired configuration, and inserting the human tissue into a human body with the tissue in the retainer wherein said step of applying pressure against the tissue removed from the human body includes forcing fluid out of the human tissue, said step of inserting the human tissue into a human body is performed with the human tissue in a defluidized condition.

3. A method of using human tissue comprising the steps of removing tissue from a human body, applying pressure against the tissue removed from the human body, forcing fluid out of the tissue removed from the human body during performance of said step of applying pressure against the tissue removed from the human body to thereby defluidize the tissue removed from the human body, and inserting the human tissue into a human body with the human tissue in a defluidized condition to enable the human tissue to absorb fluid after the human tissue has been inserted into a human body.

4. A method as set forth in claim 3 further including enclosing the tissue removed from the human body with a retainer, said step of inserting the human tissue into a human body with the human tissue in a defluidized condition includes inserting the human tissue into the human body with the human tissue in the retainer.

5. A method of using human tissue, said method comprising the steps of removing tissue from a human body, enclosing the tissue removed from the human body with a retainer, said step of enclosing the tissue removed from the human body with a retainer includes enclosing the tissue removed from the human body with a retainer formed of material which expands when the retainer is in the human body, applying pressure against the tissue removed from the human body, and inserting the human tissue into a human body with the tissue in the retainer.

6. A method of using human tissue, said method comprising the steps of removing tissue from a human body, enclosing the tissue removed from the human body with a retainer, said step of enclosing the tissue removed from the human body with a retainer includes enclosing the tissue with a retainer formed of a material which expands when the material comes into contact with body fluids, applying pressure against the tissue removed from the human body, and inserting the human tissue into a human body with the tissue in the retainer.

7. A method of using human tissue, said method comprising the steps of removing tissue from a human body, enclosing the tissue removed from the human body with a retainer, said step of enclosing the tissue removed from the human body includes enclosing human tissue with a retainer formed of a material which expands when the material comes into contact with body fluids, and inserting the human tissue into a human body with the tissue in the retainer, said step of inserting the human tissue into a human body includes inserting the retainer into a human body at a location where the retainer is exposed to body fluids.

8. A method of using human tissue, said method comprising the steps of removing tissue from a human body, enclosing the tissue removed from the human body with a retainer, applying pressure against the tissue removed from the human body to shape the tissue removed from the human body to a desired configuration, and inserting the human tissue into a human body with the tissue in the retainer, said step of enclosing the tissue removed from the human body with a retainer includes enclosing the tissue removed from the human body with a flexible mesh having openings through which human tissue can grow when the retainer is in a human body.

9. A method of using human tissue, said method comprising the steps of removing tissue from a human body, enclosing the tissue removed from the human body with a retainer, applying pressure against the tissue removed from the human body to shape the tissue removed from the human body to a desired configuration, and inserting the human tissue into a human body with the tissue in the retainer, said step of enclosing the tissue removed from the human body with a retainer includes enclosing the tissue removed from the human body with a cage formed of filaments which define openings through which human tissue can grow when the retainer is in a human body.

10. A method of using human tissue, said method comprising the steps of removing tissue from a human body, enclosing the tissue removed from the human body with a retainer, applying pressure against the tissue removed from the human body to shape the tissue removed from the human body to a desired configuration, and inserting the human tissue into a human body with the tissue in the retainer, said step of enclosing the tissue removed from the human body with a retainer includes enclosing the human tissue with a retainer having openings in the retainer to enable human tissue to grow through the openings after inserting the human tissue into a human body.
