Abstract
Official abstract text for this publication.
The bioabsorbable implant described has a porous body formed of bioabsorbable materials that have an in vivo life span of at least 2 weeks, preferably at least three weeks and not greater than 20 weeks, preferably no greater than ten weeks. The implant has a scaffolding structure which facilitates tissue in-growth and ultimately tissue replacement of the scaffolding structure. The implant has a radiopaque imaging agent at least at the exterior margins and an orientation plurality of radiopaque elements in the interior of implant. The implant preferably has three radiopaque elements within the interior that form a plane within the implant interior.
First claim
Opening claim text (preview).
What is claimed is: 1. An implant for a body cavity, comprising a body formed of a bioabsorbable material having a porosity sufficient to ensure tissue in-growth before significant bio-absorption of the implant, a radiopaque imaging agent which facilitates imaging of exterior margins of the implant and an interior orientation marker comprised of a plurality of radiopaque elements spaced inwardly from the exterior margins of the implant to facilitate relative orientation between the implant and a radiation source, wherein the plurality of radiopaque elements include at least three radiopaque elements arranged to form a plane within the interior of the implant wherein the plurality of radiopaque elements consists of three radiopaque elements which are located at apices of an equilateral triangle within the interior of the implant to form the plane.
