The Orbus LifeStent XL SDS Biliary Endoprosthesis is indicated for the palliation of malignant neoplasms in the biliary tree.
The LifeStent XL SDS Biliary Endoprosthesis consists of a balloon expandable stent which is I ne Enehein AL SDD Dipercutaneous transluminal angioplasty (PTA) balloon catheter which acts as the delivery system. The stent is a permanently implanted device used to maintain patency of a major bile duct obstructed by tissue of an impinging tumor. The flexible, balloon expandable stent is made by laser cutting an open lattice design into a 316L stainless steel tube. The stent is supplied mounted onto a PTA balloon catheter, inserted percutaneously to the diseased site, and expanded by balloon inflation. The systems are available with expanded diameter of 100mm at stent lengths of 17, 27, 37mm.
The provided text describes a 510(k) premarket notification for a medical device, the LifeStent XL SDS Biliary Endoprosthesis. This submission focuses on demonstrating substantial equivalence to a predicate device rather than a new clinical study involving AI or human readers. Therefore, many of the requested categories (e.g., sample size for test set, number of experts, MRMC study, training set details) are not applicable to this type of submission.
Here's an analysis based on the available information:
1. A table of acceptance criteria and the reported device performance
Since this is a substantial equivalence submission, the "acceptance criteria" are implied to be substantial equivalence to the predicate device in terms of design, materials, performance, and intended use. The "reported device performance" refers to the results of in vitro tests comparing the new device to the predicate.
| Acceptance Criteria (Implied for Substantial Equivalence) | Reported Device Performance |
|---|---|
| Same intended use | Intended for the palliation of malignant neoplasms in the biliary tree (Identical to predicate) |
| Identical material properties | Stent made of 316L stainless steel; delivery system is a PTA balloon catheter (Identical to predicate) |
| Similar performance properties | "Orbus protocols ensure that the LifeStent XL SDS Biliary Endoprosthesis perform in a manner substantially equivalent to the predicate devices during in vitro tests such as deployment, expansion force, compression force, dimensions, corrosion susceptibility, visual appearance, balloon performance, expansion damage, and balloon tensile strength." |
| Similar packaging | Similar packaging |
| Similar sterilization methods | Similar sterilization methods |
| Biocompatibility | Similar to predicate |
| Technological characteristics | Comparisons of new and predicate devices show technical characteristics (materials, performance, biocompatibility, sterilization, packaging) are identical or substantially equivalent. |
2. Sample size used for the test set and the data provenance
- Sample Size for Test Set: Not applicable. The submission relies on in vitro testing for substantial equivalence, not a clinical test set from patients.
- Data Provenance: Not applicable. The data is from internal in vitro testing performed by Orbus Medical Technologies, Inc.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
- Number of Experts: Not applicable. Ground truth from experts is not relevant for this type of in vitro substantial equivalence testing.
- Qualifications of Experts: Not applicable.
4. Adjudication method for the test set
- Adjudication Method: Not applicable. There was no clinical test set requiring adjudication.
5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
- MRMC Study: No. This is a medical device submission focused on in vitro performance and substantial equivalence to a predicate device, not an AI-assisted diagnostic tool.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
- Standalone Performance: No. This device is a physical medical implant (stent) and a delivery system, not an algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
- Type of Ground Truth: Not applicable in the clinical sense. For in vitro testing, the "ground truth" would be established engineering specifications and measurement standards.
8. The sample size for the training set
- Sample Size for Training Set: Not applicable. This device does not involve a "training set" in the context of machine learning or AI.
9. How the ground truth for the training set was established
- Ground Truth for Training Set: Not applicable.

510(k) Statement
Description: 8.
The LifeStent XL SDS Biliary Endoprosthesis consists of a balloon expandable stent which is I ne Enehein AL SDD Dipercutaneous transluminal angioplasty (PTA) balloon catheter which acts as the delivery system. The stent is a permanently implanted device used to maintain patency of a major bile duct obstructed by tissue of an impinging tumor. The flexible, balloon expandable stent is made by laser cutting an open lattice design into a 316L stainless steel tube. The stent is supplied mounted onto a PTA balloon catheter, inserted percutaneously to the diseased site, and expanded by balloon inflation. The systems are available with expanded diameter of 100mm at stent lengths of 17, 27, 37mm.
Intended Use: 9.
The LifeStent XL SDS Billary Endoprosthesis are intended for the palliation of malignant neoplasms in the biliary tree.
Technological Characteristics: 10.
Comparisons of the new and predicate devices were designed to show that the technical characteristics such as materials, performance properties, biocompatibility, method of sterilization, and packaging are identical or substantially equivalent.
{1}------------------------------------------------
Performance Data: 11.
Orbus protocols ensure that the LifeStent XL SDS Biliary Endoprosthesis perform in a manner substantially equivalent to the predicate devices during in vitro tests such as deployment, expansion force, compression force, dimensions, corrosion susceptibility, visual appearance, balloon performance, expansion damage, and balloon tensile strength.
Conclusion 12.
Since the LifeStent XL SDS Biliary Endoprosthesis, comprised of the Ø 8-12 mm LifeStent (K023121) and the Opti-Plast XT catheter (K941706), has the same intended use, identical material properties, similar performance properties, packaging, and sterilization methods, it may be considered substantially equivalent to the predicate devices cited in (7). These devices are a line extension to the LifeStent XL 8 and 9mm Biliary Endoprosthesis previously cleared per K040550.
