TLDR
In this paper, a solution containing a radioactive isotope depositing substance in solution is provided and placed into contact with the stent or any other substrate material capable of receiving the isotope.Abstract:
An apparatus and method of forming a radioactive stent having a radioactive layer. A solution containing a radioactive isotope depositing substance in solution is provided and placed into contact with the stent or any other substrate material capable of receiving the radioactive isotope. The radioactive isotope is deposited on the stent or substrate material. Preferably a phosphorous isotope is used and the solution is polymerized forming polymer chains containing the radioactive isotope. In this embodiment, the phosphorous is bonded with the substrate material in a phosphorous-oxygen-phosphorous network.read more

TL;DR: In this article, a system for locating and defining a target location within a human body is described, which can include at least one marker, a probe, and a detector for use in locating the markers by providing information to a surgeon that is representative of changes in proximity between the probe and the marker.
Patent
Miniature resonating marker assembly
TL;DR: In this paper, an inert encapsulation member encapsulates the signal element therein and defines a geometric shape of the resonating marker assembly, which has a geometric center point substantially coincident with the magnetic center point along at least a first axis of the signal elements.

Intra-arterial stent with the capability to inhibit intimal hyperplasia
TL;DR: In this article, a radioisotope material which forms part of the stent can be used to decrease the rate of arterial reclosure by decreasing stent thrombogenicity.
Patent
Minimally invasive medical device for providing a radiation treatment

Intracoronary Radiation Before Stent Implantation Inhibits Neointima Formation in Stented Porcine Coronary Arteries
Ron Waksman,Keith A. Robinson,Ian R. Crocker,Michael B. Gravanis,Spencer J. Palmer,Chris Wang,Gustavo D. Cipolla,Spencer B. King +7 more
TL;DR: Endovascular radiation before coronary stenting reduces neointima formation and may further reduce the restenosis rate after stent implantation.

Method and devices for preventing restenosis after angioplasty
TL;DR: In this paper, the incidence of restenosis after angioplasty is reduced by exposing the potentially stenotic site to radiation from a source within the same vascular structure in which the site is located.
