The Instylla Microcatheter 1.2 is intended for use in super selective anatomy for peripheral diagnostic and interventional procedures. The Instylla Microcatheter 1.2 can be used for the infusion of diagnostic, embolic, or therapeutic materials into vessels.

The Instylla Microcatheter 1.2 includes a single lumen, multipurpose catheter intended for use in the peripheral vasculature. The basic operating principle is to advance the microcatheter through an outer guiding catheter and track coaxially over a steerable guidewire in order to access the treatment site. The microcatheter lumen is able to accommodate steerable guidewires that are ≤0.010in (0.25mm) in diameter. Once the target region has been accessed, the microcatheter can be used to deliver diagnostic, embolic, or therapeutic materials into vessels. The microcatheter has a 1.2Fr (0.40mm) OD with a constant flexibility along its length. The ID of the microcatheter is 0.012in (0.30mm) along its length. The proximal end of the microcatheter incorporates a standard luer hub to enable the attachment of accessories, and a strain relief with a feature that allows for flexibility and securement inside a Tuohy-Borst with side-port adapter, for maintaining position inside a guiding catheter as needed. The microcatheter has a radiopaque marker at the distal tip to aid in fluoroscopic visualization. A 4Fr Tuohy-Borst with side-port adapter, a short extension adaptor, a long extension adapter and a duckbill check-valve are also included. The Instylla Microcatheter is available in 122cm, 142cm and 162cm usable lengths.

This FDA 510(k) summary describes a device, the Instylla Microcatheter 1.2, which is essentially a modification of a previously cleared predicate device (Instylla Microcatheter K200744). Therefore, the acceptance criteria and performance data mainly focus on demonstrating that the modified device's performance is equivalent to or better than the predicate, especially regarding the changes made.

Here's a breakdown of the requested information based on the provided text:

1. Table of Acceptance Criteria and Reported Device Performance

The document states that the Instylla Microcatheter 1.2 "met the predetermined acceptance criteria ensuring substantial equivalence to the predicate device." However, specific numerical acceptance criteria values and reported performance values are not explicitly provided in this summary for most tests. The summary lists the types of tests performed.

The Instylla Microcatheter is intended for use in super selective anatomy for peripheral diagnostic and interventional procedures. The Instylla Microcatheter can be used for the infusion of diagnostic, embolic, or therapeutic materials into vessels.

The Instylla Microcatheter includes a single lumen, multipurpose catheter intended for use in the peripheral vasculature. The basic operating principle is to advance the microcatheter through an outer guiding catheter and track coaxially over a steerable guidewire in order to access the treatment site. The microcatheter lumen is able to accommodate steerable guidewires that are ≤0.014in (0.36mm) in diameter. Once the target region has been accessed, the microcatheter can be used to deliver diagnostic, embolic, or therapeutic materials into vessels.

The microcatheter has a 1.7Fr (0.56mm) OD with a constant flexibility along its length. The ID of the microcatheter is 0.016in (0.41mm) along its length. The proximal end of the microcatheter incorporates a standard luer hub to enable the attachment of accessories, and a strain relief with a feature that allows for flexibility and securement inside a Tuohy-Borst adapter, for maintaining position inside a guiding catheter as needed. The microcatheter has a radiopaque marker at the distal tip to aid in fluoroscopic visualization. A 4Fr Tuohy-Borst with side-port adapter, a short extension adaptor, a long extension adapter and a duckbill check-valve are also included. The Instylla Microcatheter is available in 122cm, 142cm and 162cm usable lengths.

This document describes the Instylla Microcatheter with check-valve connector and asserts its substantial equivalence to a previously cleared predicate device (Instylla Microcatheter, K191731). As such, the study focuses on verifying that the modified device meets the same performance criteria as the predicate, rather than establishing entirely new acceptance criteria or conducting a clinical effectiveness study.

The provided text describes Instylla, Inc.'s K191731 510(k) submission for their Instylla Microcatheter. The document outlines the device's characteristics, its comparison to predicate devices, and the performance and safety studies conducted to demonstrate substantial equivalence.

Here's an analysis of the acceptance criteria and the study that proves the device meets them, based on the provided text, while noting limitations in the information for certain requested points:

Acceptance Criteria and Device Performance for Instylla Microcatheter (K191731)

The acceptance criteria for the Instylla Microcatheter revolved around demonstrating substantial equivalence to a predicate device (CrossCath Support Catheter, K093052) through various performance benchmarks and safety assessments. Since this is a 510(k) submission, the "acceptance criteria" are implied by the comprehensive pre-clinical testing conducted to show that the device performs as safely and effectively as the predicate, and does not raise new questions of safety or effectiveness.

1. Table of Acceptance Criteria and Reported Device Performance

The text does not explicitly list numerical "acceptance criteria" values for each test, but it clearly states that the Instylla Microcatheter "met the predetermined acceptance criteria" for all tests and that "No new safety or performance issues were raised during testing."

Given the context of a 510(k), the implied acceptance criterion for each test is that the Instylla Microcatheter performs comparably to the predicate device or within recognized safety and effectiveness standards for such devices.
