Intended Use
Tayman Medical AccuGuide is used to mount disposable 18 gauge x 20 centimeter automated biopsy needles to the CLI 4900 Utrasound Probe manufactured by Capistrano Labs for the purpose of accurately guiding the needle to the site where the biopsy sample is to be taken.
Device Description
Tayman Medical Inc., AccuGuide comprises a steel spring mounting clip, a stainless steel mounting tab and a stainless steel biopsy needle guide tube. The Tayman Medical AccuGuide is comprised of three basic components: the probe clamp, the mounting tab, and the biopsy needle guide tube. Probe Clamp - the probe clamp is made of medical grade hard chrome plated steel it provides a spring force to hold the Tayman Medical AccuGuide to the ultrasound probe. The probe clamp does not contact the patient. Mounting Tab - the mounting tab is made of stainless steel. It provides a common joining point for the other components and acts as a stabilizer between the Tayman Medical AccuGuide and the ultrasound probe. The mounting tab does not contact the patient. Biorsy Needle Guide Tube - the biopsy needle guide tube is made of stainless steel. It guides the needle along the predetermined path. This component contact intact tissue. This component is designed in a low profile with a smooth, rounded tip.
More Information

No
The device description focuses on mechanical components for guiding a biopsy needle and does not mention any software, algorithms, or data processing that would indicate AI/ML.

No
The device is a needle guide used for biopsies, which is a diagnostic procedure, not a therapeutic one. It facilitates the biopsy procedure but does not directly treat a disease or condition.

No

Explanation: The device is a guide for a biopsy needle, which is used for sample collection, not for diagnosing. The actual diagnosis would be made by analyzing the collected biopsy sample.

No

The device description explicitly lists physical components made of steel and stainless steel, indicating it is a hardware device, not software-only.

Based on the provided information, the Tayman Medical AccuGuide is not an IVD (In Vitro Diagnostic) device.

Here's why:

  • IVD devices are used to examine specimens derived from the human body (like blood, urine, tissue) in vitro (outside the body) to provide information for diagnosis, monitoring, or screening.
  • The Tayman Medical AccuGuide is a device used in vivo (within the body) to guide a biopsy needle during an ultrasound-guided procedure. Its purpose is to facilitate the collection of a tissue sample, not to analyze the sample itself.

The device description and intended use clearly indicate its function is to physically guide a needle into the body for biopsy, which is an in vivo procedure.

Intended Use / Indications for Use

The Tayman Medical Biopsy Guide is used to ensure the appropriate placement of the biopsy needle for exact tissue sampling during ultrasonically guided diagnostic biopsy procedures.

The Tayman Medical AccuGuide is used in conjunction with currently available CLI 4900 Utrasound Probe manufactured by Capistrano Labs and 18 gauge x 20 centimeter automated biopsy needles. Such as:

HRI 2000 manufactured by International Ultrasound 14 West Forest Avenue, Englewood, NJ 07631 and

Ultra-Cut Automated Biopsy System manufactured by Medical Device Technologies 4445 S.W. 35" Terrace, Suite 310, Gainesville, FL 32608.

Indications for Use: Tayman Medical AccuGuide is used to mount disposable 18 gauge x 20 centimeter automated biopsy needles to the CLI 4900 Utrasound Probe manufactured by Capistrano Labs for the purpose of accurately guiding the needle to the site where the biopsy sample is to be taken.

§ 892.1560 Ultrasonic pulsed echo imaging system.

(a)
Identification. An ultrasonic pulsed echo imaging system is a device intended to project a pulsed sound beam into body tissue to determine the depth or location of the tissue interfaces and to measure the duration of an acoustic pulse from the transmitter to the tissue interface and back to the receiver. This generic type of device may include signal analysis and display equipment, patient and equipment supports, component parts, and accessories.(b)
Classification. Class II (special controls). A biopsy needle guide kit intended for use with an ultrasonic pulsed echo imaging system only is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 892.9.

  • Predicate Device: This device is substantially equivalent to the Teknar, Inc. Biopsy Needle Guide Attachments, manufactured by Teknar Corporation located at 1279 Maurer Industrial Drive, St. Louis, MO 63127. This device was the subject of Premarket Notification K881605.
    Device Description: Tayman Medical Inc., AccuGuide comprises a steel spring mounting clip, a stainless steel mounting tab and a stainless steel biopsy needle guide tube.

Intended Use:

The Tayman Medical Biopsy Guide is used to ensure the appropriate placement of the biopsy needle for exact tissue sampling during ultrasonically guided diagnostic biopsy procedures.

The Tayman Medical AccuGuide is used in conjunction with currently available CLI 4900 Utrasound Probe manufactured by Capistrano Labs and 18 gauge x 20 centimeter automated biopsy needles. Such as:

HRI 2000 manufactured by International Ultrasound 14 West Forest Avenue, Englewood, NJ 07631 and

Ultra-Cut Automated Biopsy System manufactured by Medical Device Technologies 4445 S.W. 35" Terrace, Suite 310, Gainesville, FL 32608.

Clinical and Non-Clinical Similarities and Differences:

The Tayman Medical AccuGuide is constructed of stainless steel and medical grade hard chrome plated steel.

The Teknar Biopsy Guide is constructed of stainless steel.

Teknar manufactures two basic variants of the Accu Guide, with rails and without rails. There is no functional difference between the two, they are offered to accommodate different biopsy needles. The Tayman Medical AccuGuide is offered in the without rails variant only.

The Tayman Medical AccuGuide is comprised of three basic components: the probe clamp, the mounting tab, and the biopsy needle guide tube.

Probe Clamp - the probe clamp is made of medical grade hard chrome plated steel it provides a spring force to hold the Tayman Medical AccuGuide to the ultrasound probe. The probe clamp does not contact the patient.

Mounting Tab - the mounting tab is made of stainless steel. It provides a common joining point for the other components and acts as a stabilizer between the Tayman Medical AccuGuide and the ultrasound probe. The mounting tab does not contact the patient.

Biorsy Needle Guide Tube - the biopsy needle guide tube is made of stainless steel. It guides the needle along the predetermined path. This component contact intact tissue. This component is designed in a low profile with a smooth, rounded tip.

The predicate device, the without rails variant of Teknar Accu Guide, is comprised a mounting ring and the biopsy needle guide tube.

Mounting Ring - the mounting ring attaches to the ultrasound probe by tightening a thumbscrew. This finction duplicates the spring mounting feature of the Tayman Medical AccuGuide. The Mounting ring also serves to stabilize the guide and provide a common joining point for the other components. This function duplicates the mounting tab of the Tayman Medical AccuGuide. The mounting ring does not contact the patient.

Biopsy Needle Guide Tube - the biopsy needle guide tube is made of stainless steel. It guides the needle along the predecemined path. Its function is identical to that of the biopsy needle guide tube of the Tayman Medical AccuGuide. This component contacts intact tissue.

The Tayman Medical Standard Biopsy Needle Guide is biocompatible with the body tissue that it is made of the same materials as the predicate device in the patient contact areas. The device is sterilized using steam cycles, which have been validated by the overkill method.
