Intended Use

The Texan LONGhorn™ is intended for use as a tool to retrieve and manipulate foreign bodies from distal peripheral vessels of the cardiovascular system.

Device Story

Texan LONGhorn™ is a catheter-based foreign body retrieval device. It consists of a nitinol wire loop with a platinum core for radiopacity, a push-rod shaft, an inner member for 0.018" guidewire passage, and an outer member with a hemostasis Y-connector. Operated by a physician in a clinical setting, the device is advanced into peripheral vessels. The loop is deployed and manipulated to surround a foreign body; the user then retracts a red-capped knob to tighten the loop around the object. The handle is locked via a hemostasis valve, and the device is withdrawn with the captured object. The device allows for contrast injection and flushing via a side port. It benefits patients by providing a minimally invasive method to remove misplaced or foreign objects from the cardiovascular system.

Clinical Evidence

No clinical data. Evidence consists of bench testing (tensile strength verification) and an animal study to evaluate safety, efficacy, and operational characteristics compared to the predicate device.

Technological Characteristics

Nitinol wire loop with platinum core; catheter-based system with Y-connector, Tuohy-Borst connector, and push-rod mechanism. Compatible with 0.018" guidewires. Features include torque control, steerability, and contrast injection capability. Manual operation; no software or electronic components.

Indications for Use

Indicated for retrieval and manipulation of foreign bodies from distal peripheral vessels of the cardiovascular system in patients requiring such intervention.

Regulatory Classification

Identification

An embolectomy catheter is a balloon-tipped catheter that is used to remove thromboemboli, i.e., blood clots which have migrated in blood vessels from one site in the vascular tree to another.

#### Device Description:

The Texan LONGhorn™ is comprised of the following:

- A nitinol wire formed into a loop. The wire is secured distally to the catheter body; the . proximal wire end is attached to a shaft that functions as a push-rod, and passes through a catheter. The "loop" portion of the wire has a platinum core for enhanced radiopacity.
- An inner member accepting an 0.018" guidewire. The proximal end of the inner carrier . extends out the side port of a Y-connector allowing for the physician to manipulate the guidewire thru the device.
- An outer member. The proximal end is connected to a hemostasis Y-connector, having a . side port and Tuohy-Borst connector on the central port for securing the hypotube.
- the Tuohy-Borst connector allows the physician to secure the loop size once it is u deploved to the desired diameter
- the side port of the Y-connector allows access to the guidewire-dedicated lumen and 트 the T-connector to allow for contrast injection and flushing

The loop is activated by moving the red capped knob and handle axially. The device should be manipulated in such a way that the loop can surround the foreign body. To capture the foreign body, the user shall slowly tighten the loop around the foreign body by retracting the red capped knob proximally while the device is held stationary in position. Once the loop is tightened around the foreign body, the handle and shaft shall be locked by rotating the hemeostasis valve connected to the proximal end of the handle clockwise. Retrieval of the foreign body is performed by slowly withdrawing the Texan LONGhorn™ TX30120060 and the foreign body as a unit into the sheath.
