Description of Tantalum Marker Rings
Tantalum Marker Bands are marker rings manufactured from Tantalum. They are typically used in the field of medical technology. They are affixed to specific locations on medical devices such as catheters or implants to provide a visual marker. Given that Tantalum is biocompatible, has a high density and is radiographically transparent, Tantalum Marker Bands are utilised in radiological and interventional procedures. They assist clinicians in locating and monitoring specific areas, thereby facilitating precise diagnosis and treatment. Marker bands are produced by cutting small tubes (Tantalum and Platinum-Iridium capillaries) that act as radiopaque markers during procedures such as angioplasty and other minimally invasive catheter interventions.

Applications of Tantalum Marker Bands
1. Surgical positioning: Tantalum Marker Bands are used during surgical procedures by attaching them to catheters or implants. They enable clinicians to accurately locate surgical targets.
2. Radiology: During radiological investigations and diagnostic imaging, Tantalum Marker Bands provide clear radiographic markers. They support the evaluation of tissue structures.
3. Interventional procedures: In procedures such as angiography or stenting, Tantalum Marker Bands are applied to mark the position of instruments. This supports precise manipulation and treatment.
4. Oncology: Tantalum Marker Bands are used in radiotherapy and oncological procedures to clearly mark tumour locations and delineate treatment areas.
5. Manufacturing of medical devices: Tantalum Marker Bands form an integral part of many medical devices. They offer a visual reference that facilitates routine monitoring and management.
