The E-Cath STIM acc. Tsui System is indicated for delivery of medication for regional anesthesia and pain management. Route of administration may be intraoperative, percutaneous, or perineural. To assist the physician pinpoint the area of application an electrical stimulus can be applied to the conduction needle removal, to assist the physician pinpoint conduction catheter placement, an electrical stimulus can be applied to the conduction catheter tip via the catheter adapter.
The E-Cath STIM acc. Tsui System is contraindicated for the epidural space.
The Over-the-needle (OTN) Catheter Systems are available in different designs with cannula and catheter in different sizes. The system includes: SonoPlex cannula, permanent cannula, E-Cath catheter, locking cap.
The provided document is a 510(k) premarket notification for a medical device (E-Cath STIM acc. Tsui). It is a special 510(k) for a device modification, intending to combine features from previously cleared devices. The document mainly focuses on demonstrating substantial equivalence to predicate devices through bench testing and compliance with recognized standards, rather than clinical studies with human participants. Therefore, several of the requested categories, such as "multi-reader multi-case (MRMC) comparative effectiveness study," "sample size for the test set," "number of experts," "adjudication method," and "standalone (i.e., algorithm only) performance" are not applicable to this type of submission.
Here's a breakdown of the available information:
1. Table of Acceptance Criteria and the Reported Device Performance:
| Test | Acceptance Criteria | Reported Device Performance |
|---|---|---|
| Needle: Bending Rigidity | According to EN ISO 9626: ≤ 0.48mm under an applied force of 15N by a span width of 17.5mm. | The bending rigidity of the subject/predicate/reference device's needles is less than 0.46mm. Conclusion: In compliance. |
| Needle: Breaking Resistance | According to EN ISO 9626: Not to break during a bending test for 20 periods at an angle defined by cannula size. | The tested cannulas did not break during the test. Conclusion: In compliance. |
| Needle: Bonding to Hub | According to EN ISO 7864: Pull-off force ≥ 44N. | For the subject/predicate/reference device's needles, a force significantly higher than the target value has to be applied. Conclusion: In compliance. |
| Needle: Penetration Force | EN 13097: No specific pass/fail criteria; objective comparison only. | The subject/predicate/reference device's needles show appropriate penetration/insertion forces. Compared to the predicate device, PAJUNK's needles are in compliance. Conclusion: In compliance. |
| Catheter: Leak Tightness | Internal protocols based on risk assessment and clinical evaluation (standard DIN EN 1618 does not define criteria). Catheter system must be tight for a defined period and pressure. | All systems are tight during the test for both the subject device and the predicate/reference devices. Conclusion: In compliance. The subject/predicate/reference device's catheters meet the acceptance criterion. |
| Catheter: Tensile Strength | Internally defined acceptable value to be met without tear-off (standard DIN EN 10555-1 and DIN EN 1618 do not define criteria). | The catheters of the E-Cath Systems meet the acceptance criterion (without tear-off). Conclusion: In compliance. The subject/predicate/reference device's catheters meet the acceptance criterion. |
| Catheter: Flow Rate | Internally defined by the sponsor based on risk management and clinical evaluation (standard DIN EN 10555-1 and DIN EN 1618 do not define criteria). | The flow rate of the tested E-Cath catheter meets the acceptance criterion. The subject/predicate/reference device's catheters meet the acceptance criterion and have proven to supply appropriate flow rates. |
2. Sample Size Used for the Test Set and the Data Provenance:
- Sample Size: Not explicitly stated for each test, but implied to be sufficient for demonstrating compliance with the referenced ISO/EN standards for medical device components. The tests refer to "tested cannulas" and "tested catheters."
- Data Provenance: Bench testing, compliance with international standards (ISO, EN, DIN). Results are compared against predicate and reference devices, implying these are internal company data.
- Retrospective/Prospective: Not applicable in the context of bench testing for a device modification. The tests are performed on the device itself.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and the Qualifications of Those Experts:
- Not applicable. The ground truth for these tests is defined by international standards (e.g., ISO 9626, ISO 7864, DIN EN 1618, DIN EN 10555-1) and internal protocols for performance criteria where standards are not specific. This does not involve expert medical opinion for "ground truth" in the diagnostic sense.
4. Adjudication Method for the Test Set:
- Not applicable. Performance is measured against predefined, objective, quantifiable acceptance criteria established by international standards or internal engineering/risk assessment protocols.
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:
- Not applicable. This is a medical device (anesthesia conduction kit), not an AI diagnostic or image analysis system.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
- Not applicable. This is a physical medical device.
7. The Type of Ground Truth Used (expert consensus, pathology, outcomes data, etc.):
- The "ground truth" for the device's performance is established by compliance with recognized international standards for medical device components (e.g., mechanical properties, sterility, biocompatibility) and internal engineering/risk assessment protocols where standards allow for manufacturer-defined criteria (e.g., leak tightness, tensile strength, flow rate).
8. The Sample Size for the Training Set:
- Not applicable. This is not a machine learning model, so there is no "training set."
9. How the Ground Truth for the Training Set was Established:
- Not applicable. As above, this is not a machine learning model.

PAJUNK® GmbH Medizintechnologie is submitting this Special 510(k) for a modification of the Over-the-needle (OTN) Catheter System, brand name "E-Cath", intended to be brand-named E-Cath STIM acc. Tsui.
It is considered a Class II medical device as defined in 21 CFR §868.5140 anesthesia conduction kit, product code CAZ (Subsequent Codes: 21 CFR §868.5120 catheter, conduction, anesthetic, product code BSO and 21 CFR §868.5150 Anesthesia conduction needle, product code BSP.
The intended use as well as the individual components this system consist of have been cleared in different 510(k)s sent in earlier by the sponsor and shall be combined under a new device name. So the E-Cath K152952 shall be equipped with a stimulation catheter (in K152952 the catheter described is a non-stimulation catheter but the stimulation catheter in K152952 is already optionally listed) as it is described in the 510(k)s for the second predicate device StimuLong K033018.
The intended use of the E-Cath STIM acc. Tsui shall be extended to one more specific use as defined in an earlier 510(k) which serves as reference device.
In order to make the clearance status of the subject device – E-Cath STIM acc. Tsui – more obvious, sponsor decided to compile the data in one individual standalone Special 510(k) describing the modifications more clearly.
The technique – over the needle – is rarely identified in submissions with identical indications for use. Usually it is not mentioned whether the technique of placing a catheter is "over the needle" or "through the needle". This detail in application method does not make any difference in evaluating safety, effectiveness and efficacy of the device itself from the technological point of view.
So substantial equivalence of the modifications is based on earlier submissions by the sponsor and verified through Design verification process.

Technology Characteristics:
Besides bench testing recognized standards are applicable for the subject device. Compliance is claimed for the standards listed below:
EN ISO 9626: Stainless steel needle tubing for manufacture of medical devices.
The cannula tubing of the cannula included in the subject device fulfills the requirements according to EN ISO 9626. Technological characteristics like material, surface finish, cleanliness, limits for acidity and alkalinity and size designation are complied with.
Regarding the requirement of bending rigidity and breaking resistance the cannula tubes are tested according to the standard (Annex C and D).
According to the standard the acceptance criterion of the bending rigidity for the cannula is ≤ 0,48mm. The applied force was 15N by a span width of 17,5mm. The bending rigidity of the tested cannulas is less than 0,46mm. Therefore the cannula meets this acceptance criterion.
The acceptance criterion of the breaking resistance is: not to break.
During the test the cannula is bended an angle, which is defined in the standard based on to the cannula size, for 20 periods. Means the cannula is bended in two directions. The tested cannulas did not break during the test.
Therefore the cannula meets this acceptance criterion.
The cannulas fulfill all the requirements of EN ISO 9626.
EN ISO 7864: Sterile hypodermic needles for single use
The cannulas used comply with the requirements according to EN ISO 7864. Technology characteristics like Cleanliness, Limits for acidity or alkalinity, Limits for extractable metals, size designation, needle hub, sheath, tolerances, patency of lumen, freedom from defects, lubricant, needle point, packaging and labeling are in compliance.
Regarding the requirement of bond between hub and needle tube the cannula is tested according to the standard.
The acceptance criterion for the bond between hub and needle tube (pull-off force) is ≥44N.
Therefore the cannula meets the acceptance criterion.
The cannulas fulfill all the requirements of EN ISO 7864.
EN 13097: Hypodermic needles
The penetration force of the cannula is tested according to the standard (Annex D). The standard does not include acceptance criteria but is meant to provide an objective test method.
Compared to the predicate device PAJUNK's needles are in compliance.

DIN EN 10555-1: Intravascular catheters - sterile and single use catheters - Part 1: General requirements
The catheter fulfills the requirements of the standard DIN EN 10555-1. Technology characteristics like X-ray visibility, biocompatibility, surface, hub, lateral openings, catheter tip, size designation, packaging and labelling are met.
Tensile force, tightness and flow rate are tested according to the standard.
The standard does not give an acceptance criterion for the tensile force.
Due to this, PAJUNK® set the acceptance criterion for this to an internally defined acceptable value to be met without tear off. The catheters of the E-Cath Systems meet the acceptance criterion.
For the test on leak tightness, the catheter system has to be tight for a defined period of time as well as a defined pressure. All systems are tight during the test.
Also for the flow rate no acceptance criterion is given specification of PAJUNK® catheters regarding the flow rate is internally defined by the sponsor based on risk management and clinical evaluation. The flow rate of the tested E-Cath catheter meets the acceptance criterion.
The requirement of high-performance injection does not apply because the catheter is not intended for high-performance injection.
The catheters fulfill all the requirements.
DIN EN 1618: Catheters other than intravascular catheters - Test methods for common properties
The catheter of the E-Cath System fulfills the requirements of the standard DIN EN 1618. Requirements like tensile properties, tightness, flow rate as well as the safety of connectors are tested according to the standard.
The standard does not give an acceptance criterion for the tensile force.
Due to this, PAJUNK® set the acceptance criterion for this to an internally defined mustvalue without tear off.
The catheters of the E-Cath System meet the acceptance criterion.
For the test on tightness, the catheter system has to be tight for a defined period of time as well as a defined pressure. All systems are tight during the test.
Also for the flow rate no acceptance criterion is given.
The specification of PAJUNK® catheters regarding the flow rate is defined as internal must-value. The flow rate of the tested E-Cath catheter meets the acceptance criterion.
The catheters and needles fulfill all the requirements for the essential technological characteristics.
As proven in earlier Submissions of the predicate device as well as of the reference devices basic fundamental technological characteristics as described above are met.
