Purpose / Clinical Use

Used for dilation of the ureter prior to ureteroscopy and stone manipulation, providing a working channel for introduction of a ureteroscope and other devices.

Key Features

• Optimal radiopacity for visualization.
• Long tapered tip supports atraumatic entry and can reduce the need for repeated dilation.
• Smooth surface for controlled introduction.
• Hydrophilic- coated versions may be offered where specified.

Purpose / Clinical Use

Fascial dilator sets are used to create and progressively enlarge a tract for nephrostomy catheter access, with graduated sizes intended to support controlled dilation.

Key Features

• Radiopaque polymer construction for procedural visualization.
• Smooth surface assists guidewire- based introduction.
• Used before nephroscopy and for stone- management access.
• Hydrophilic- coated versions may be available.

Purpose / Clinical Use

Designed to dilate the intramural tunnel and ureter in one step. Used for contrast injection to assess submucosal tunnelling or for anaesthetic jelly during stone dislodgement.

Key Features

• Radiopaque for visualization.
• Long tapered tip designed to avoid sequential dilation.
• Smooth surface for atraumatic entry.
• Hydrophilic and non- hydrophilic configurations may be considered.

Purpose / Clinical Use

Designed for dilation of the percutaneous tract and establishment of a working channel into the kidney during PCNL using an Amplatz sheath.

Key Features

• Gradual tapered tip for placement and maneuverability.
• Smooth surface for controlled dilation.
• Radiopaque design for visualization.
• Set configuration can combine fascial dilators, renal dilators, sheath, guiding catheter and radiopaque dilation sheath.

Purpose / Clinical Use

An S- shaped urethral dilator configuration is intended to follow the natural curvature of the male urethra during dilation. Contains an S- shape urethral dilator set; external clinical literature specifically describes S- shaped coaxial dilators inserted over a guidewire.

Key Features

• S- shaped geometry follows the male urethral curvature.
• Smooth surface for easier introduction.
• Side hole can be provided for drainage in the design.
• Hydrophilic coating may be offered.

Purpose / Clinical Use

Intended to dilate urethral strictures, negotiate the true path of the urethral lumen and provide access toward the bladder.

Key Features

• Radiopaque for visualization.
• Long tapered tip for controlled advancement.
• Smooth surface for atraumatic entry.
• Hydrophilic and non- hydrophilic configurations may be considered.

Purpose / Clinical Use

An access sheath with dilator establishes a conduit for passage of endoscopes or other instruments during endoscopic urological procedures. The tapered dilator helps introduce the sheath over a guidewire.

Key Features

• Tapered dilator tip for smooth insertion and ureteral dilation.
• Hydrophilic coating may reduce insertion friction.
• Radiopaque markers can support fluoroscopic positioning.
• Sheath and dilator can be supplied as a matched system.

Purpose / Clinical Use

Used for dilation of the penile urethral meatus. The supplied also notes that a female meatal dilator configuration may be available.

Key Features

• Simple, controlled dilation geometry.
• Male and female configurations can be offered.
• Smooth surface intended for controlled introduction.
• Final size progression and material to be specified by Zirve.

Purpose / Clinical Use

Used to dilate urethral strictures and establish or maintain bladder access through the urethra for cystoscopy.

Key Features

• Radiopaque for visualization.
• Smooth surface for atraumatic entry.
• Side hole available for drainage in the configuration.
• Hydrophilic- coated versions may be available.
• Graduated sets support progressive dilation.

Purpose / Clinical Use

Graduated vaginal dilator sets are used for progressive vaginal dilation in clinical and post- procedural settings. External product references describe smooth, graduated dilators supplied as multi- size sets.

Key Features

• Graduated sizes support progressive dilation.
• Smooth, rounded profiles are commonly used for controlled insertion.
• Medical- grade polymer or silicone configurations are available in external references.
• Set sizes and dimensions should be selected according to the intended clinical application.

Purpose / Clinical Use

Balloon dilators provide controlled radial expansion of a target passage. The supplied specifically describes a ureteral balloon dilator for ureteral strictures, stone management and ureteroscopy.

Key Features

• Dual- lumen catheter with non- compliant distal balloon in the supplied.
• Controlled inflation pressure up to 20 ATM in the supplied configuration.
• Kink- resistant shaft and tapered distal end.
• Radiopaque marker bands for fluoroscopic positioning.
• Hydrophilic coating for smooth insertion.

Purpose / Clinical Use

A peel- away introducer combines an inner dilator with an outer sheath that can be separated and removed after catheter or instrument placement. Configuration for establishing a conduit during endoscopic urological procedures.

Key Features

• Inner tapered dilator supports tract establishment.
• Peel- away sheath separates after placement to avoid disturbing the indwelling device.
• Radiopaque sheath configurations are used in some systems.
• Sterile single- use configurations are common in the referenced devices.

Purpose / Clinical Use

Rhino- type tracheostomy dilators are used over a guidewire to enlarge the tracheal stoma during percutaneous tracheostomy procedures. Single- step tapered dilators and loading dilators for tracheostomy tube placement.

Key Features

• Tapered geometry supports progressive stomal dilation.
• Guidewire- based use is described in percutaneous tracheostomy techniques.
• Hydrophilic distal coating is used in some reference devices.
• Depth markings can assist positioning in certain configurations.
