Abstract
A blood reintroduction system may include a canister configured to collect blood. The system may include an inlet configured to be fluidly connected to a first tubing in fluid communication with an aspiration system configured to apply aspiration to a vasculature of a patient. The system may include a first outlet configured to be fluidly connected to a second tubing in fluid communication with an aspiration pump. The system may include a second outlet configured to interact with a blood reintroduction device, wherein the blood reintroduction device is configured to withdraw the blood collected inside the canister. The system may include a filter positioned inside a flow path leading to the second outlet.
Core Innovation
The invention relates to a blood reintroduction system for aspiration thrombectomy that includes a housing having a chamber configured to collect blood. The housing has an inlet configured to fluidly connect the chamber to a first tubing in fluid communication with an aspiration catheter, a first outlet configured to fluidly connect the chamber to a second tubing in fluid communication with an aspiration pump, and a second outlet configured to interact with a blood reintroduction device.
A removably couplable filter assembly is provided for thrombus capture during aspiration and reintroduction. The filter assembly includes a first filter configured to be positioned between an interior portion of the housing and an opening of the second outlet when the filter assembly is coupled to the housing, and a second filter configured to be positioned between the inlet and the aspiration catheter, where the second filter captures thrombus as blood flows through the first tubing.
The housing positioning and internal arrangement are configured to reduce air draw and excessive blood loss by shaping the collected-blood region. The inlet and the first outlet are positioned on a top portion of the housing, while the second outlet is positioned on a bottom portion of the housing.
Claims Coverage
The document contains two independent claims. They each center on a blood reintroduction system with a housing that collects aspirated blood, routes blood through an inlet and aspiration pump path, and provides a removably couplable filter assembly for thrombus capture and controlled placement relative to a bottom outlet.
Blood reintroduction system with top inlet/first outlet and bottom second outlet
A housing having a chamber configured to collect blood, with an inlet configured to fluidly connect the chamber to a first tubing in fluid communication with an aspiration catheter, a first outlet configured to fluidly connect the chamber to a second tubing in fluid communication with an aspiration pump, and a second outlet configured to interact with a blood reintroduction device, where the inlet and the first outlet are positioned on a top portion of the housing and the second outlet is positioned on a bottom portion of the housing.
Removably couplable filter assembly with positioned first and second filters
A filter assembly removably couplable to the housing, wherein the filter assembly comprises a first filter configured to be positioned between an interior portion of the housing and an opening of the second outlet when the filter assembly is coupled to the housing, and a second filter configured to be positioned between the inlet and the aspiration catheter, the second filter configured to capture thrombus as blood flows through the first tubing.
Filter positioned inside the chamber on the bottom portion when coupled
When the filter assembly is coupled to the housing, the filter assembly is positioned on a bottom portion of the housing and at least partially inside the chamber, in a system with an inlet and a first outlet positioned on a top portion of the housing and a second outlet positioned on a bottom portion of the housing.
Overall, the independent claims cover a blood reintroduction system with top and bottom placement of inlet and outlets and a removably couplable filter assembly, including a first filter positioned between housing interior and the second outlet opening and a second filter positioned between the inlet and the aspiration catheter to capture thrombus.
Stated Advantages
Reducing air draw.
Reducing excessive blood loss.
Documented Applications
Blood capture and reintroduction during aspiration thrombectomy.
