Kit and method for use during ventricular restoration

Abstract

Apparatuses and methods are provided to reconstruct an enlarged left ventricle of a human heart, using a shaper, having a size and shape substantially equal to the size and shape of an appropriate left ventricle, wherein the shaper is adapted to be temporarily placed into the enlarged left ventricle during a surgical procedure. Another aspect of one embodiment comprises a ventricular patch adapted for placement into the left ventricle of a heart made from a sheet of biocompatible material, and having a plurality of markings coupled to the sheet, wherein the markings are configured in distinct patterns for post operatively evaluating movement of the patch. In another aspect of one embodiment, a device is presented, comprising of a handle and a sizing template adapted to be coupled to the handle. Such components are also presented as a kit for use during ventricular restoration surgery.

         29 . A method for reconstructing an enlarged left ventricle of a human heart, the method comprising: 
 opening the enlarged left ventricle;    positioning a shaper into the enlarged left ventricle, wherein the shaper comprises a predetermined shape, wherein the predetermined shape acts as a pattern to reconstruct the left ventricle about the shaper;    reforming the enlarged left ventricle over the shaper;    removing the shaper from the enlarged left ventricle; and    closing the opening using by coupling a patch to the ventricle, such that the enlarged left ventricle is reconstructed into a shape and volume of an appropriate left ventricle.    
     
     
         30 . The method of  claim 29 , further comprising assessing the size and shape of the opening.  
     
     
         31 . The method of  claim 29 , further comprising assessing the size and shape of the opening comprising placing a sizing template into the opening in the left ventricle for assessing the size of the opening, wherein the periphery of the sizing template is substantially the size and shape of the opening.  
     
     
         32 . The method of  claim 29 , excluding at least some non-viable tissue.  
     
     
         33 . The method of  claim 29 , further comprising suturing a patch to an interior of the ventricle.  
     
     
         34 . The method of  claim 29 , further comprising: 
 pulling the enlarged left ventricle over the shaper;    suturing the ventricle such that an interior surface of the ventricle substantially conforms to the shape of the shaper; and    partially closing the opening.    
     
     
         35 . The method of  claim 29 , further comprising: 
 determining a demarkation line between non-viable tissue and viable tissue;    excluding at least some of the non-viable tissue;    placing at least one suture along the demarkation line; and    pulling the suture such that the left ventricle is pulled around the shaper.    
     
     
         36 . The method of  claim 29 , further comprising defining a size of the patch using a lip coupled to a periphery of a sizing template.  
     
     
         37 . The method of  claim 29 , further comprising cutting the patch from biocompatible material using a cutting edge coupled to a sizing template.  
     
     
         38 . The method of  claim 29 , further comprising evaluating movement of the patch post operatively using markings configured in distinct patterns on the patch.  
     
     
         39 . A method for reconstructing an enlarged left ventricle of a human heart, the method comprising: 
 opening the enlarged left ventricle;    positioning a shaper into the enlarged left ventricle, wherein the shaper comprises a predetermined shape, wherein the predetermined shape acts as a pattern to reconstruct the left ventricle about the shaper;    excluding at least some non-viable tissue;    removing the shaper from the enlarged left ventricle; and    closing the opening using by coupling a patch to the ventricle, such that the enlarged left ventricle is reconstructed into a shape and volume of an appropriate left ventricle.    
     
     
         40 . The method of  claim 29 , further comprising assessing the size and shape of the opening.  
     
     
         41 . The method of  claim 29 , further comprising assessing the size and shape of the opening comprising placing a sizing template into the opening in the left ventricle for assessing the size of the opening, wherein the periphery of the sizing template is substantially the size and shape of the opening.  
     
     
         42 . The method of  claim 29 , further comprising suturing a patch to an interior of the ventricle.  
     
     
         43 . The method of  claim 29 , further comprising: 
 pulling the enlarged left ventricle over the shaper;    suturing the ventricle such that an interior surface of the ventricle substantially conforms to the shape of the shaper; and    partially closing the opening.    
     
     
         44 . The method of  claim 29 , further comprising: 
 determining a demarkation line between non-viable tissue and viable tissue;    placing at least one suture along the demarkation line; and    pulling the suture such that the left ventricle is pulled around the shaper.    
     
     
         45 . The method of  claim 29 , further comprising defining a size of the patch using a lip coupled to a periphery of a sizing template.  
     
     
         46 . The method of  claim 29 , further comprising cutting the patch from biocompatible material using a cutting edge coupled to a sizing template.
