Summary
The Target® Tetra™ coils demonstrate promising short-term safety and efficacy for treating intracranial aneurysms, including ruptured cases. Further studies are needed to confirm long-term occlusion rates.
Area of Science:
- Neurosurgery
- Endovascular Therapy
- Cerebrovascular Disease
Background:
- Intracranial aneurysms require advanced treatment options.
- Neuroendovascular technologies have significantly improved aneurysm management.
- Target® Tetra™ coils represent a recent innovation in this field.
Purpose of the Study:
- To evaluate the safety and efficacy of Target® Tetra™ coils.
- To describe the usage nuances of these coils in aneurysm treatment.
- To report outcomes in a series of treated aneurysms.
Main Methods:
- Retrospective, two-center study of consecutive aneurysm cases.
- Inclusion of both ruptured and unruptured aneurysms.
- Data collection on clinical, technical, and imaging characteristics.
Main Results:
- 80 aneurysms in 75 patients were treated with 100% technical success.
- Minor technical issues occurred in 2.5% of cases (coil migration/detachment).
- Adequate occlusion rate was 92.6% at short-term follow-up (excluding adjuncts).
Conclusions:
- Target® Tetra™ coils show initial safety and efficacy for intracranial aneurysms.
- Short-term outcomes are encouraging for both ruptured and unruptured cases.
- Long-term aneurysm occlusion rates require further investigation.

Charging Conductors By Induction
The Earth is a good conductor of electricity, and it is so big that it can be considered an infinite source or sink of charges. It can easily exchange charges with any matter.
Generally, conductors like metals do not allow any excess charge to be present on them. Any excess charge added to metals easily flows away, for example, when a metal is placed on the Earth. This process is called earthing.
However, conductors can be charged by a process called induction. For example, consider charging a...

Induced Electric Fields: Applications
An important distinction exists between the electric field induced by a changing magnetic field and the electrostatic field produced by a fixed charge distribution. Specifically, the induced electric field is nonconservative because it does not work in moving a charge over a closed path. In contrast, the electrostatic field is conservative and does no net work over a closed path. Hence, electric potential can be associated with the electrostatic field but not the induced field. The following...
Electrodes: Overview
Electrochemical measurements are conducted in an electrochemical cell composed of various components that control and measure the current and potential. One fundamental component is electrodes, conductive materials that enable electron transfer reactions at their surfaces.
There are two main types of electrodes in electrochemical cells. The first type, known as the working or indicator electrode, has a potential that is sensitive to the analyte's concentration and reacts to changes in the...

Series and Parallel Inductors
In electrical circuits, integrating inductors into the toolkit of passive elements requires navigating the intricacies of series and parallel combinations involving these components. Practical circuits often feature configurations of multiple inductors, and understanding how to determine their equivalent inductance is vital.

Three-Winding Transformers
Three identical single-phase transformers can be configured to form a three-phase transformer connection, which involves high-voltage and low-voltage windings. The high-voltage windings are denoted by capital letters A-B-C, while the low-voltage windings are labeled with lowercase letters a-b-c, representing their respective phases. This notation helps distinguish between the high and low voltage sides of the transformer.
