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" [cite: The RA device 100, the catheter system 200, and the tubing system 300 can be the same as or similar to one or more of the retraction and aspiration devices, catheter systems, and tubing systems disclosed in U.S. Pat. No. 9,526,864, filed Jun. 9, 2015, and titled “RETRACTION AND ASPIRATION DEVICE FOR TREATING EMBOLISM AND ASSOCIATED METHODS,” which is incorporated herein by reference in its entirety.]
Publication/Filing Date: Filed June 9, 2015. [cite: The RA device 100, the catheter system 200, and the tubing system 300 can be the same as or similar to one or more of the retraction and aspiration devices, catheter systems, and tubing systems disclosed in U.S. Pat.

Brief Description: This patent describes retraction and aspiration devices, catheter systems, and tubing systems for treating embolism. The current patent (US12016580B2) states that its 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. [cite: The RA device 100, the catheter system 200, and the tubing system 300 can be the same as or similar to one or more of the retraction and aspiration devices, catheter systems, and tubing systems disclosed in U.S. Pat. No. 9,526,864, filed Jun. 9, 2015, and titled “RETRACTION AND ASPIRATION DEVICE FOR TREATING EMBOLISM AND ASSOCIATED METHODS,” which is incorporated herein by reference in its entirety.] This implies that US 9,526,864 lays foundational aspects for the retraction and aspiration components of the system.
Potential Anticipation (35 U.S.C. § 102): Given that US12016580B2 explicitly states its components can be "the same as or similar to" those in US 9,526,864, it is highly probable that US 9,526,864 anticipates at least the core elements related to the RA device, catheter system, and tubing system as broadly recited in the independent claims (Claim 1, Claim 11, and Claim 18) of US12016580B2. The novelty of US12016580B2, therefore, would likely rest on the specific improvements and functionalities beyond those broadly described in US 9,526,864, particularly regarding the ability for multiple passes without full guide catheter removal and the design of the attachment member for clot retention prevention. For instance, the specific mechanisms for "unsealing" and "resealing" the attachment member (e.g., the first valve insert 650, the second valve insert 860, or the garrote valve 1108) and their cooperative function in preventing clot stripping during withdrawal, as detailed in claims, would be key differentiators. If the basic RA device, catheter, and tubing system are directly taught or rendered obvious by US 9,526,864, then any claims in US12016580B2 that do not add a novel and non-obvious improvement to these core components could be anticipated.

The patent also references U.S. Provisional Patent Application No. 62/554,931, filed Sep. 6, 2017, titled "HEMOSTASIS VALVES AND METHODS OF USE," which is reproduced in Appendix D. This provisional application relates specifically to hemostasis valves, which are a component of the attachment member 1108.

[cite: The attachment member 1108 can be, for example, a garrote valve (e.g., a hemostasis valve) as disclosed in provisional U.S. Patent Application No. 62/554,931, filed Sep. 6, 2017, and titled “HEMOSTASIS VALVES AND METHODS OF USE,” which is reproduced in Appendix D to this application, and which is incorporated herein by reference in its entirety.]
Publication/Filing Date: Filed September 6, 2017. [cite: The attachment member 1108 can be, for example, a garrote valve (e.g., a hemostasis valve) as disclosed in provisional U.S. Patent Application No. 62/554,931, filed Sep. 6, 2017, and titled “HEMOSTASIS VALVES AND METHODS OF USE,” which is reproduced in Appendix D to this application, and which is incorporated herein by reference in its entirety.]
Brief Description: This provisional patent application describes hemostasis valves and their methods of use. Specifically, the attachment member 1108 in US12016580B2 is noted as being similar to a garrote valve disclosed in this provisional application. [cite: The attachment member 1108 can be, for example, a garrote valve (e.g., a hemostasis valve) as disclosed in provisional U.S. Patent Application No. 62/554,931, filed Sep. 6, 2017, and titled “HEMOSTASIS VALVES AND METHODS OF USE,” which is reproduced in Appendix D to this application, and which is incorporated herein by reference in its entirety.] This suggests that the garrote valve's design and function, particularly its ability to create a hemostatic seal and to be actuated between sealed and unsealed configurations, are taught by this prior art.
Potential Anticipation (35 U.S.C. § 102): The provisional application 62/554,931 likely anticipates aspects of the attachment member 1108, particularly its structure as a garrote valve and its ability to provide a hemostatic seal and to change between a collapsed/sealed state and an expanded/open state. This would impact claims (e.g., Claim 1, Claim 11, and Claim 18) that describe the attachment member's specific valve mechanisms and its ability to create a continuous lumen or to be actuated for sealing and unsealing. If the provisional application fully describes the features of the attachment member 1108 that enable the "unsealing" and "resealing" for clot material passage without significant retention, then claims relying on these features might be anticipated.
