Abstract
Disclosed herein are an implant with an attachment feature and a method for attaching to the same. The implant may include a cavity with a porous layer disposed within a non-porous layer wherein the non-porous layer defines a chamber. The chamber may receive and confine liquefiable material and direct liquefiable material to permeate through the porous layer. A method of attaching a device to the implant may include liquefying a liquefiable portion of the device and allowing the liquefied material to interdigitate with the second layer and then solidify to prevent pullout.
Claims15
An implant having one or more cavities, each cavity comprising:
- a non-porous first layer defining a chamber having an opening;
- a porous second layer;
- wherein the second layer is disposed within the chamber such that when a liquefiable material is received in the chamber through the opening, the liquefiable material permeates into the second layer and is confined within the chamber by the first layer.
An implant comprising:
- a non-porous first portion;
- a cavity defined within the first portion, the cavity having an opening;
- a porous layer;
- wherein the porous layer is disposed within the cavity such that when a liquefiable material is received in the cavity through the opening, the liquefiable material permeates into the porous layer and is confined within the chamber by the first portion.
