Intended Use

The TightRail Mini 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

Intra-operative device for percutaneous tissue dilation; facilitates removal of cardiac leads, indwelling catheters, and foreign objects. Consists of proximal handle drive mechanism and distal dilation sheath; packaged with outer support sheath. Physician advances, withdraws, and rotates device about target object. Trigger actuation on handle activates rotary dilation mechanism at distal terminus; rotation of inner shaft translates to axial actuation of dilation mechanism via internal cam path. Dilation of surrounding tissue and fibrous attachments enables object removal. Used in clinical/surgical settings by physicians.

Clinical Evidence

No clinical data required. Substantial equivalence supported by bench testing, including dimensional verification, mechanical stress testing (tensile, torsional, axial load), radio-detectability, corrosion resistance, simulated use, and biocompatibility (cytotoxicity, sensitization, reactivity, toxicity, complement activation, hemolysis, thrombogenicity, genotoxicity, pyrogenicity). Testing leveraged from predicate K140047 with additional verification for the modified length.

Technological Characteristics

Rotating mechanical dilator sheath; 9F to 11F diameter; 15.5 cm effective length. Mechanical actuation via proximal handle trigger and internal cam path. Materials and design identical to predicate K140047. Sterilization per AAMI TIR:28-2009.

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.

### Device Description

The TightRail Mini Rotating Dilator Sheaths is an intra-operative device. The device consists of a proximal handle drive mechanism with a distal dilation sheath. The sheath is packaged with an 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 The dilator sheath is advanced, withdrawn and rotated about the lead, catheter or foreign object to be removed.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 sheath. 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 11 F. The nominal effective length of the effective length of the TightRail Mini is 15.5 cm (6.1").

# Intended and Indications for Use

The TightRail Mini 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

# Technological Characteristics

The TightRail Mini Rotating Dilator Sheaths features the same performance characteristics as the predicate device (K140047 - TightRail® Rotating Mechanical Dilator Sheath). There are no significant changes to the function of the device. Changes have been made to length of the distal dilation sheath. The predicate device features a working length of 47.5cm (18.7") whereas the subject device features a working length of 15.5cm (6.1"). The subject and predicate are otherwise identical with regards to technological characteristics.
