Most Relevant Prior Art for US Patent 12156669

US patent 12156669, titled "Single insertion delivery system for treating embolism and associated systems and methods," cites U.S. Pat. No. 9,526,864 as a key piece of prior art.

Prior Art Reference: U.S. Pat. No. 9,526,864

• Full Citation: U.S. Pat. No. 9,526,864, filed Jun. 9, 2015, and titled "RETRACTION AND ASPIRATION DEVICE FOR TREATING EMBOLISM AND ASSOCIATED METHODS."
• Publication/Filing Date: Filed on June 9, 2015. The publication date is not explicitly stated in the provided text, but it is referred to as an "issued" patent, implying it was published.
• Brief Description: US 9,526,864 discloses retraction and aspiration devices, catheter systems, and tubing systems for treating embolism. The present patent, US 12156669, states that its clot retrieval system (including the RA device 100, catheter system 200, and tubing system 300) "can be the same as or similar to" those disclosed in US 9,526,864. This indicates that US 9,526,864 describes foundational components and methods for retraction and aspiration in embolectomy procedures.
• Potential Anticipation under 35 U.S.C. § 102: Without access to the specific claims of US 12156669, it is difficult to definitively state which claims are potentially anticipated. However, given the explicit statement that the current patent's core components (RA device, catheter system, tubing system) can be "the same as or similar to" those in US 9,526,864, it is highly probable that any claims in US 12156669 that broadly cover these fundamental elements, their general structure, or their combined operation for retraction and aspiration in embolism treatment, could be anticipated by US 9,526,864. This would particularly apply to claims describing the overall system architecture and the basic functions of simultaneously retracting a portion of the catheter system and aspirating through it, as these are directly mentioned in the description of how the present patent relates to US 9,526,864.

I am unable to provide further prior art analysis or an overview of the independent claims of US patent 12156669, as the claims section was not included in the provided patent text. Similarly, without the full text of US 9,526,864, a detailed analysis of specific claim anticipation is not possible.
