Expert Review of Medical Devices
|September 7, 2023
Summary
This review analyzes 62 bone biopsy device patents to understand strategies for sampling, severing, and harvesting bone tissue. The findings aim to inspire the development of improved bone biopsy devices for better patient outcomes.
Area of Science:
- Medical Devices
- Biotechnology
- Orthopedics
Background:
- Bone biopsies are crucial for diagnosing hematologic diseases.
- Current bone biopsy procedures, though minimally invasive, can cause patient discomfort, particularly if repeated.
Purpose of the Study:
- To provide a comprehensive overview of bone biopsy devices documented in patent literature.
- To identify and categorize strategies used in bone biopsy device design.
Main Methods:
- A systematic search of the Espacenet patent database was conducted using classification and keywords.
- Patents were filtered based on pre-set eligibility criteria, resulting in 62 included patents.
Main Results:
- The review categorized patents based on strategies for biopsy sampling, severing, and harvesting.
- Many patents encompassed solutions for multiple stages of the bone biopsy process.
Conclusions:
- The comprehensive overview of existing bone biopsy device strategies can inform the design of novel devices.
- Understanding patented techniques may lead to more effective and less invasive bone biopsy procedures.

01:40Bone Remodeling
38.4K
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.
