Summary
Metallic airway stents, used for decades to keep airways open, have evolved significantly. Modern advancements have improved their safety and efficacy, leading to a resurgence in their use for various indications.
Area of Science:
- Interventional Pulmonology
- Biomedical Engineering
- Respiratory Medicine
Background:
- Airway stenting is a common interventional pulmonology procedure.
- Metallic stents are used to maintain tracheobronchial tree patency.
- Historically, stents were temporary or used when surgery was not an option.
Purpose of the Study:
- To review the historical evolution of metallic airway stents.
- To discuss technological advancements in metallic airway stent design.
- To outline contemporary clinical indications for metallic endobronchial stents.
Main Methods:
- Review of historical data and literature on airway stenting.
- Analysis of technological progression from early to modern metallic stents.
- Examination of current practices and patient selection for stent implantation.
Main Results:
- Early metallic stents were simple stainless steel devices.
- Current metallic stents are sophisticated, often hybrid, and made from advanced alloys.
- Improved understanding of stent-airway interactions and post-procedural care have enhanced safety.
Conclusions:
- Metallic airway stenting has a long history with significant technological evolution.
- Advancements in design and care have led to renewed clinical acceptance.
- Metallic endobronchial stents are increasingly indicated for maintaining airway patency.

02:37Metallic Solids
20.6K
Metallic solids such as crystals of copper, aluminum, and iron are formed by metal atoms. The structure of metallic crystals is often described as a uniform distribution of atomic nuclei within a “sea” of delocalized electrons. The atoms within such a metallic solid are held together by a unique force known as metallic bonding that gives rise to many useful and varied bulk properties.

Group 1 elements are soft and shiny metallic solids. They are malleable, ductile, and good conductors of heat and electricity. The melting points of the alkali metals are unusually low for metals and decrease going down the group, while the density increases going down the group with the exception of potassium (Table 1).

The hemoglobin in the blood, the chlorophyll in green plants, vitamin B-12, and the catalyst used in the manufacture of polyethylene all contain coordination compounds. Ions of the metals, especially the transition metals, are likely to form complexes.
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...

29.8K
Transition metals are defined as those elements that have partially filled d orbitals. As shown in Figure 1, the d-block elements in groups 3–12 are transition elements. The f-block elements, also called inner transition metals (the lanthanides and actinides), also meet this criterion because the d orbital is partially occupied before the f orbitals.
