Abstract
Methods are provided for generating intraluminal prosthetic implants designed to fit onto specific anatomical locations within regions which are stable in terms of their motion in time.
Claims13
A method for generating a patient-specific intraluminal implant, comprising the steps of:
- a) identifying for a patient, based on information regarding variation in function of time of the anatomy of said lumen in an anatomical area of interest for placing said intraluminal implant, anatomical regions in said anatomical area showing greater stability in time;
- b) identifying and selecting locations in the anatomical regions identified in step (a) which are suitable for use as a base for the contact surface of a intraluminal implant, and
- c) generating a patient-specific intraluminal implant based on the information obtained in steps (a)-(b), wherein the generated patient-specific intraluminal implant comprises an outer surface having one or more patient-specific anatomy engagement surfaces or contact points corresponding to the locations of the anatomical regions of the lumen wall identified and selected in step (b).
A method of generating a patient-specific heart valve docking structure for a heart valve of a patient, the method comprising:
- (a) identifying for said patient, anatomical regions in an anatomical area of said heart valve showing greater stability in time;
- (b) identifying and selecting the locations in the identified anatomical regions suitable for use as a base for at least one contact surface of the heart valve docking structure, and
- (c) generating the patient-specific heart valve docking structure based on the information obtained in steps (a) and (b), such that wherein the generated patient-specific heart valve docking structure comprises a body structure which links a distal toroidal attachment structure and a proximal toroidal attachment structure, and wherein said distal toroidal attachment structure comprises patient-specific anatomy engagement surfaces or contact points corresponding to anatomical regions identified on the outflow side of the patient's heart valve anatomy, and wherein said proximal toroidal attachment structure comprises patient-specific anatomy engagement surfaces or contact points corresponding to anatomical regions identified on the inflow side of the patient's heart valve anatomy.
