Abstract

A patient-specific intraluminal implant is disclosed. The implant may comprise a body structure spanning a specific patient's lumen and an outer surface thereof comprising one or more patient-specific anatomy engagement surfaces or contact points corresponding to patient-specific anatomical regions of the lumen wall. The patient-specific anatomical regions of the lumen wall may include pre-operatively identified anatomical regions showing greater stability in time.

First claim

What is claimed is:

1 . A patient-specific intraluminal implant comprising:
a body structure spanning a specific patient's lumen and an outer surface thereof, the outer surface comprising one or more patient-specific anatomy engagement surfaces or patient-specific contact points corresponding to patient-specific anatomical regions of the lumen wall, wherein said patient-specific anatomical regions of the lumen wall are pre-operatively identified anatomical regions showing greater stability in time.

2 . The patient-specific intraluminal implant of claim 1 , wherein the patient-specific intraluminal implant is an intraluminal docking structure for a functional element, wherein the intraluminal docking structure further includes an inner surface comprising one or more docking features configured to detachably engage a functional element with the inner surface of the intraluminal docking structure.

3 . The patient-specific intraluminal implant of claim 1 , wherein the patient-specific intraluminal implant is a heart valve or a heart valve docking structure, and
wherein the body structure of the patient-specific intraluminal implant further comprises:
a distal toroidal attachment structure combined with the one or more patient-specific anatomy engagement surfaces or contact points corresponding to anatomical regions on the outflow side of the patient's heart valve anatomy; and
a proximal toroidal attachment structure combined with the one or more patient-specific anatomy engagement surfaces or contact points corresponding to anatomical regions on the inflow side of the patient's heart valve anatomy; and
wherein the pre-operatively identified anatomical regions have a lower degree of variation in time compared to other anatomical regions on the inflow or outflow side of the patient's heart valve anatomy.

4 . The patient-specific intraluminal implant of claim 2 , wherein the functional element is one of a stent, graft, stent-graft, vena cava filter, tubular expandable framework, heart valve or heart valve frame.

5 . The patient-specific intraluminal implant of claim 2 , wherein the functional element a heart valve, and wherein the heart valve comprises a mitral valve.

6 . The patient-specific intraluminal implant of claim 2 , wherein the functional element is a heart valve, and wherein the heart valve comprises a tricuspid valve.

7 . The patient-specific intraluminal implant of claim 1 , wherein the docking station is foldable.

8 . The patient-specific intraluminal implant of claim 2 , wherein the docking features comprise anchoring components.

9 . The patient-specific intraluminal implant of claim 8 , wherein the anchoring components comprise one or more of a barb, a clip, a staple, a post, an eyelet, or a hook.

10 . The patient-specific intraluminal implant of claim 4 , wherein the intraluminal docking structure and the functional element are manufactured as a single part through additive manufacturing.

11 . The patient-specific intraluminal implant of claim 10 , wherein the intraluminal docking structure is manufactured in bio-absorbable material.

12 . The patient-specific intraluminal implant of claim 2 , wherein the functional element is one or more of a valve, plug, mesh, sieve, or drug eluting component.

13 . The patient-specific intraluminal implant of claim 1 , wherein the outer surface of the intraluminal implant is configured to comprise patient-specific anatomy engagement surfaces, and wherein the patient-specific anatomy engagement surfaces are both in regions at the distal end and at the proximal end of the lumen wall.

14 . The patient-specific intraluminal implant of claim 1 , wherein the at least part of the implant is transitionable from a collapsed state to an expanded state.

15 . The patient-specific intraluminal implant of claim 14 , wherein the implant is configured to retract radially in a collapsed state and extend radially in an expanded state.

16 . The patient-specific intraluminal implant of claim 1 , wherein the body structure comprises a central hollow body.

17 . The patient-specific intraluminal implant of claim 16 , wherein the central hollow body connects a distal toroidal attachment structure and a proximal toroidal attachment structure.
