Abstract
Abstract Apparatus and method for stapling a prosthesis in-situ includes an adjustable annuloplasty band and a positioning instrument for holding and positioning the band in a heart valve annulus. The instrument includes a curvature adjustable portion at one end for adjusting the band to conform to the heart valve annulus. Another end of the instrument, opposite the one end, includes a curvature adjustment actuating means. A stapling device attaches the band to the annulus simultaneously with the band being held in the annulus by the positioning instrument.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
92 words
A method for attaching a prosthesis in-situ comprising the steps of: making a first and a second incision in a native heart; providing an annuloplasty band; providing a positioning instrument for holding and positioning the band in a valve annulus of the native heart; inserting the positioning instrument into the first incision; positioning the annuloplasty band in engagement with the valve annulus; inserting a stapling instrument into the second incision; and stapling the band to the annulus simultaneously with the band being held in engagement with the annulus by the positioning instrument.
Claim 2
Independent Claim
92 words
A method for attaching a prosthesis in-situ comprising the steps of: making a first and a second incision in a native heart; providing an annuloplasty band; providing a positioning instrument for holding and positioning the band in a valve annulus of the native heart; inserting the positioning instrument into the first incision; positioning the annuloplasty band in engagement with the valve annulus; inserting a stapling instrument into the second incision; and stapling the band to the annulus simultaneously with the band being held in engagement with the annulus by the positioning instrument.
Claim 3
Dependent Claim
27 words
The method as defined in claim 1 further comprising the steps of: adjusting a portion of the positioning instrument for adjusting the band to fit the annulus.
Claim 4
Dependent Claim
12 words
The method as defined in claim 1 wherein the band is flexible.
Claim 5
Dependent Claim
23 words
The method as defined in claim 1 wherein the instrument has a fixed curvature for positioning the band at the heart valve annulus.
Claim 6
Dependent Claim
12 words

Claim 7
Dependent Claim
25 words
The method as defined in claim 5 wherein the instrument includes a movable curvature adjustment actuating means at another end thereof, opposite the one end.
Claim 8
Dependent Claim
29 words
The method as defined in claim 6 further comprising the step of: moving the curvature adjustment actuating means for adjusting the band to conform to the heart valve annulus.
Claim 9
Dependent Claim
14 words
The method as defined in claim 7 wherein the band is an incomplete ring.
Claim 10
Dependent Claim
26 words
The method as defined in claim 4 wherein the instrument has a curvature adjustable portion for adjusting the band to conform to the heart valve annulus.
Claim 11
Dependent Claim
19 words
The method as defined in claim 1 wherein the curvature adjustable portion is at one end of the instrument.
