Soft filled prosthesis shell with discrete fixation surfaces

Abstract

A method of augmenting or reconstructing a breast of a patient includes providing an implantable member and implanting the implantable member. The implantable member includes an exterior surface defined by an anterior face and a posterior face, wherein one of the anterior face and the posterior face includes at least one fixation region defined by a texture, roughness or sheen different from a respective texture, roughness or sheen of a balance of said one of the anterior face and posterior face. The implantable member is implanted into a breast of a patient such that the fixation region of the implantable member generally aligns with the pectoralis major muscle group or the pectoralis minor muscle group.

What is claimed is: 
     
         1 . A method of augmenting or reconstructing a breast of a patient, the method comprising:
 providing an implantable member including an exterior surface defined by an anterior face and a posterior face, wherein one of the anterior face and the posterior face includes at least one fixation region defined by a texture, roughness or sheen different from a respective texture, roughness or sheen of a balance of said one of the anterior face and posterior face; and   implanting the implantable member into a breast of a patient such that the fixation region of the implantable member generally aligns with the pectoralis major muscle group or the pectoralis minor muscle group.   
     
     
         2 . The method of  claim 1 , wherein the at least one fixation region is defined by an enhanced texture relative to said balance of said one of the anterior face and posterior face. 
     
     
         3 . The method of  claim 1 , wherein the implanting comprises aligning the fixation region relative to the pectoralis minor muscle group. 
     
     
         4 . The method of  claim 1 , wherein the fixation region comprises an elongated configuration, and the implanting comprises aligning the elongated configuration of the fixation region with the pectoralis major muscle group or the pectoralis minor muscle group. 
     
     
         5 . The method of  claim 1 , wherein the fixation region comprises a band shape. 
     
     
         6 . The method of  claim 1 , further comprising positioning the implantable member over the top of the pectoralis major muscle group. 
     
     
         7 . The method of  claim 1 , further comprising positioning the implantable member underneath the pectoralis major muscle group. 
     
     
         8 . A method of augmenting or reconstructing a breast of a patient, the method comprising:
 providing an implantable member including an exterior surface defined by a textured posterior face and a relatively less textured anterior face, wherein roughnesses of the textured posterior face and the textured anterior face permit enhanced tissue ingrowth or adhesion along the exterior surface; and   implanting the implantable member into a breast of a patient such that the implantable member is positioned over the top of the pectoralis major muscle group or underneath the pectoralis major muscle group.   
     
     
         9 . The method of  claim 8 , wherein the exterior surface of the implantable member is in contact with the pectoralis major muscle group or the pectoralis minor muscle group. 
     
     
         10 . The method of  claim 8 , wherein the exterior surface of the implantable member includes at least one fixation region. 
     
     
         11 . The method of  claim 10 , further comprising substantially aligning the fixation region with the pectoralis major muscle group. 
     
     
         12 . The method of  claim 10 , further comprising substantially aligning the fixation region with the pectoralis minor muscle group. 
     
     
         13 . The method of  claim 10 , wherein the at least one fixation region is defined by an enhanced texture relative to one of the anterior face and posterior face. 
     
     
         14 . The method of  claim 10 , wherein the fixation region comprises an elongated configuration, and the implanting comprises aligning the elongated configuration of the fixation region with the pectoralis major muscle group or the pectoralis minor muscle group. 
     
     
         15 . The method of  claim 10 , wherein the fixation region comprises a band shape. 
     
     
         16 . A method of augmenting or reconstructing a breast of a patient, the method comprising:
 providing an implantable member including an exterior surface defined by a textured posterior face and a relatively less textured anterior face, wherein roughnesses of the textured posterior face and the textured anterior face permit enhanced tissue ingrowth or adhesion along the exterior surface; and   implanting the implantable member into a breast of a patient, wherein the textured posterior face and the textured anterior face are configured to disrupt capsule formation.   
     
     
         17 . The method of  claim 16 , further comprising positioning the implantable member over the top of the pectoralis major muscle group. 
     
     
         18 . The method of  claim 16 , further comprising positioning the implantable member underneath the pectoralis major muscle group. 
     
     
         19 . The method of  claim 16 , wherein one of the anterior face and the posterior face includes at least one fixation region defined by a texture, roughness or sheen different from a respective texture, roughness or sheen of a balance of said one of the anterior face and posterior face. 
     
     
         20 . The method of  claim 19 , further comprising substantially aligning the fixation region with the pectoralis major muscle group or the pectoralis minor muscle group.
