Intended Use

The lacrimal duct catheter is intended for use during dilation of the obstructed nasolacrimal duct.

Device Story

DacryoCath is a sterile, single-use, disposable balloon catheter for dilating obstructed nasolacrimal ducts. Device consists of stainless steel hypotube core and polyethylene terephthalate balloon. Available in 2mm, 3mm, and 5mm inflated diameters. Features Y-hub with separate luer ports for balloon inflation and irrigation. Operated by physician in clinical setting; catheter inserted into canaliculus; balloon inflated to 8atm with 10cc sterile saline for 90 seconds to dilate obstruction. Markings at 10mm and 15mm proximal to balloon assist in correct placement. Irrigation port allows delivery of solutions. Device restores patency to lacrimal system, potentially relieving symptoms of obstruction, dacryocystitis, or failed dacryocystorhinostomy.

Clinical Evidence

No clinical data. Evidence consists of non-clinical bench testing including biocompatibility (ISO 10993: cytotoxicity, sensitization, irritation, acute systemic injection, pyrogenicity), mechanical performance (inflation/deflation time, fatigue, rupture, tensile strength, ISO 594-1 luer taper testing), and packaging/sterilization validation (ISO 11135).

Technological Characteristics

Materials: Stainless steel hypotube, polyethylene terephthalate balloon. Dimensions: 15.24 cm length; 2mm, 3mm, 5mm balloon diameters. Principle: Mechanical balloon dilation via 8atm saline inflation. Connectivity: None. Sterilization: Ethylene Oxide (EO) per ISO 11135. Standards: ISO 10993 (biocompatibility), ISO 594-1 (luer taper), ASTM D169 (transportation), ASTM F1929 (dye migration).

Indications for Use

Indicated for dilation of obstructed nasolacrimal duct: 2mm catheter for patients >12 and <30 months; 3mm catheter for children >30 months; 5mm catheter for adults with functional/complete nasolacrimal duct obstruction, dacryocystitis, or failed dacryocystorhinostomy.

Regulatory Classification

Identification

Lacrimal stents and intubations sets are intended to repair the lacrimal drainage system. Lacrimal stents and intubations sets are indicated for, but limited to, the treatment of epiphora in infants and adults; canalicular pathologies such as stenosis; obstruction or laceration; and conditions requiring dacryocystorhinostomy (conventional or laser); or imperforation of the nasolacrimal duct in an infant.

Description

The lacrimal duct catheter is a sterile, single use, non-pyrogenic disposable balloon catheter consisting of a semi-flexible stainless steel hypotube core and polyethylene terephthalate balloon tubing. The balloon is designed to inflate to a known diameter and length at the specific pressure. Markings are present 10 and 15 mm proximal to the beginning of the working portion of the balloon, which helps indicate when the balloon is placed correctly in the lacrimal system. The overall length of the catheter is 6 inches (15.24 cm) long. There is an opening on the distal end of the catheter hypotube to accommodate irrigation solutions. The Y-hub on the proximal end of the catheter has a luer port for inflation of the balloon catheter (labeled "inflation" with a red band) and a second luer port for irrigation through the balloon catheter (labeled "irrigation"). The balloon catheter is available in a 2 mm and 3 mm inflated diameter. The 3 mm balloon has a length of 15 mm and a deflated profile of approximately 1.1 mm. The 2 mm balloon has a length of 15 mm and a deflated profile of approximately 1.0 mm.
