Intended Use

The MobiCath Transseptal Needles are used to create the primary puncture in the interatrial septum to facilitate the passing of an introducer or catheter through the septum from the right side of the heart to the left side.

Device Story

MobiCath Transseptal Needle consists of thin-walled stainless steel cannula, ergonomic handle, two-way stopcock, and removable stylet. Used in surgical settings by physicians to create primary puncture in interatrial septum; facilitates passage of introducer or catheter from right to left heart. Handle includes pointer for curve orientation; stopcock enables air aspiration, fluid infusion, blood sampling, and pressure monitoring. Device is manual; no electronic or automated components. Modifications in this submission involve replacement of discontinued stopcock and associated handle interface adjustments, plus manufacturing improvements. Safety and efficacy verified via bench testing and biocompatibility assessment.

Clinical Evidence

Bench testing only. No clinical data provided. Testing included visual/dimensional inspection, functional testing (tensile, torque, stopcock gauging, leakage, separation force, resistance to override, ease of assembly, stress cracking, stylet retention/insertion), and comprehensive biocompatibility testing (cytotoxicity, sensitization, reactivity, systemic injection, pyrogenicity, hemocompatibility, hemolysis, PTT, platelet/leukocyte counts, complement activation).

Technological Characteristics

Stainless steel cannula; ergonomic handle; two-way stopcock. Manual operation. Biocompatible materials. Sterilization via EtO. No software, electronics, or energy source.

Indications for Use

Indicated for patients requiring transseptal puncture to facilitate passage of an introducer or catheter from the right to the left side of the heart. For prescription use by trained physicians in a surgical setting.

Regulatory Classification

Identification

A trocar is a sharp-pointed instrument used with a cannula for piercing a vessel or chamber to facilitate insertion of the cannula.

Special Controls

*Classification.* Class II (special controls). Except for trocars that are reprocessed for multiple use, the device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 870.9.

MobiCath™ Transseptal Needle Transseptal Needle Trocar DRC Class II 21 CFR 870.1390 Cardiovascular

Predicate Device:

MobiCath™ Transseptal Needle (K111644)

#### Device Description:

The MobiCath Transseptal Needles consist of a thin-walled stainless steel cannula bonded to an ergonomic handle and stopcock, and a removable stylet. The cannula is curved in the distal section to facilitate positioning in the cardiac anatomy when used in conjunction with an introducer or catheter. The handle is integrated with a pointer to show the orientation of the curve. The two-way stopcock facilitates air aspiration, fluid infusion, blood sampling, and pressure monitoring. The stylet attaches to the proximal end of the needle assembly.

#### Intended Use:

The MobiCath Transseptal Needles are used to create the primary puncture in the interatrial septum to facilitate the passing of an introducer or catheter through the septum from the right side of the heart to the left side.

#### Comparison to Predicate Device:

Greatbatch Medical proposes using an alternate stopcock for the MobiCath Trasseptal Needles. The current stopcock has been discontinued by the supplier. A similar stopcock has been tested as a replacement. A few minor design changes are required for the stopcock to interface with the handle components. In addition, a few manufacturing improvements have been proposed.

{1}------------------------------------------------

The Intended Use and Indications for Use for the MobiCath Transseptal Needles have not changed.

The fundamental scientific technology of the MobiCath Transseptal Needles has not changed. The proposed modifications do not change the needle cannula or stylet, or the manner in which the needle punctures the inter-atrial septum.

The surgical approach and procedure have not changed.

The device use environment has not changed. The device is still intended to be used under prescription use by trained physicians in a surgical setting.

The overall device design has not changed. The device still consists of a cannula, handle, stopcock and stylet and these components continue to interact in the same manner. The proposed device changes only impact the dimensions and the material formulations of the stopcock and interfacing handle components.

#### Conclusion:

Failure Modes and Effect Analysis was used to identify the performance parameters potentially affected by the design modifications. The risks were addressed through verification and validation activities. The results from these activities demonstrate that the risks have been mitigated and that no new safety or efficacy issues were raised.

· Greatbatch Medical considers the modified device to be substantially equivalent to the predicate device.
