Intended Use

The TightRail Sub-C Rotating Dilator Sheath is intended for use in patients requiring the percutaneous dilation of tissue to facilitate removal of cardiac leads, indwelling catheters, and foreign objects.

Device Story

Mechanical, intra-operative device for percutaneous tissue dilation. Consists of proximal handle drive mechanism and distal dilation catheter; packaged with optional outer support sheath. Operator (physician) advances, withdraws, and rotates device over target lead, catheter, or foreign object. Trigger actuation on handle translates rotation to axial movement of distal dilation mechanism via internal cam path. Distal mechanism dilates fibrous tissue attachments surrounding target object to facilitate removal. Used in clinical settings for lead/catheter extraction. Benefits patient by enabling removal of indwelling objects through minimally invasive percutaneous approach.

Clinical Evidence

No clinical data required. Substantial equivalence demonstrated via bench-top design verification and validation testing, including dimensional verification, tensile, torque, axial load, weld integrity, radio-detectability, corrosion resistance, and simulated use testing. Biocompatibility testing performed per standard requirements.

Technological Characteristics

Mechanical rotating dilator sheath; 9F to 13F diameters; 15.5 cm effective length. Features proximal handle trigger, distal dilation mechanism, and laser-cut hypotube shaft. Sterilization via AAMI TIR:28-2009 adoption. Biocompatibility testing includes cytotoxicity, sensitization, reactivity, systemic toxicity, complement activation, hemolysis, thrombosis, and pyrogenicity.

Indications for Use

Indicated for patients requiring percutaneous tissue dilation to facilitate removal of cardiac leads, indwelling catheters, and foreign objects.

Regulatory Classification

Identification

A vessel dilator for percutaneous catheterization is a device which is placed over the guide wire to enlarge the opening in the vessel, and which is then removed before sliding the catheter over the guide wire.

Dear Stephanie Byrum:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

### Device Description

The TightRail Sub-C Rotating Dilator Sheaths are mechanical, intra-operative devices. The devices consist of a proximal handle drive mechanism with a distal dilation catheter. The sheaths are packaged with an optional outer support sheath. The dilator sheath is advanced, withdrawn, and rotated about the lead, catheter or foreign object to be removed. Actuating the trigger on the proximal handle activates a rotary dilation mechanism sheathed at the distal terminus of the catheter. Rotation of the inner shaft is translated to axial actuation of the dilation mechanism via a cam path contained within the distal components. Actuation of the distal dilation mechanism causes dilation of tissue and fibrous attachments surrounding the object targeted for removal, thereby facilitating removal of said object. The diameter sizes range from 9 French (F) to 13 F. The nominal effective length of the TightRail Sub-C is 15.5 cm.

### Intended and Indications for Use

The TightRail Sub-C Rotating Dilator Sheath is intended for use in patients requiring the percutaneous dilation of tissue to facilitate removal of cardiac leads, indwelling catheters, and foreign objects.

# Preclinical and Clinical Data:

Preclinical and clinical data was not required to demonstrate substantial equivalence. The design characteristics of the subject device are similar to the predicate. The design verification and validation test results demonstrated that the subject device is as safe and clinically effective as the predicate device.

### Substantial Equivalence

Based on the similarities in design between the subject and predicate devices, and the performance data, the TightRail Sub-C are substantially equivalent to the previously cleared versions of the TightRail and TightRail Mini (K142546 and K150360, respectively).
