Filed:

Jul 5, 2022

Appl. No.:

17/857598

Inventors:

- Campbell CA, US
Julia Fox - San Carlos CA, US
James Jacobs - Danville CA, US

International Classification:

A61B 17/22

Abstract:

A clot capture module can include a housing, a chamber inside the housing, a window, and a filter. The window permits visual inspection of a clot inside the chamber. The clot can access the chamber via an incoming flow path configured to direct blood from an aspiration catheter to an upstream surface of the filter. An aspiration control valve can block the flow of incoming aspirated blood until actuated to permit inflow of aspirated blood. An outgoing flow path can direct blood from a downstream surface of the filter to a remote vacuum canister.

International Classification:

A61F 2/01

Abstract:

A thrombus engagement tool having a flexible shaft, a clot engagement tip, and a handle. The engagement tip may include one or more radially outwardly extending structures such as a helical thread. The helical thread can be advanced through a catheter to engage a clot. The handle may be configured to be rotated by hand. When the handle is rotated, the helical thread of the engagement tip can rotate in the same direction thereby allowing the helical threat to engage the clot. The helical thread can wrap around the flexible shaft at least about one, two, or four or more full revolutions, but in some cases no more than about ten or no more than about six revolutions.

International Classification:

A61M 1/00

Abstract:

A method of removing embolic material from a vessel with mechanical and aspiration assistance. The method comprises the steps of providing an aspiration catheter having a central lumen and a distal end, advancing the distal end of the aspiration catheter to obstructive material in a vessel, applying vacuum to the central lumen to draw clot into the central lumen, introducing a thrombus engagement tool into the central lumen, and manually manipulating the tip to engage clot between the tip and an inside wall of the central lumen.

International Classification:

A61M 39/06
A61B 17/34

Abstract:

An inserter for guiding a device through a hemostasis valve. The inserter comprises an elongate tubular body, a concave landing zone, and an axially extending slit. The elongate body tubular body of the inserter partially defines a central lumen. A method a of passing a device through a valve comprises the steps of providing an inserter having a tubular body with a split sidewall, advancing the tubular body through a valve, advancing a device through the tubular body and beyond the valve and retracting the tubular body so that the device escapes laterally from the tubular body through the split sidewall, leaving the device in place across the valve.

Abstract:

A vacuum aspiration system may be used to treat thromboembolic disease, such as deep vein thrombosis or pulmonary embolism. The system includes a housing, and a fluid flow path extending through the housing. A first catheter is in fluid communication with the flow path, and a connector is configured to place a source of aspiration in communication with the flow path. A clot container is carried by the housing. A hemostasis valve is provided in the housing, and configured to receive a second catheter and direct the second catheter through the first catheter.

International Classification:

A61B 17/22
A61M 39/06

Abstract:

An aspiration system exhibits an accelerated drop in negative pressure at the distal end of an aspiration catheter from the time of opening a valve. The system includes an aspiration pump in communication with a first chamber, and an aspiration catheter configured for placement into fluid communication with the first chamber by way of an elongate aspiration tube. A second chamber is provided between the aspiration tube and the catheter, and a valve is provided between the second chamber and the aspiration catheter. Upon opening of the valve with negative pressure at equilibrium in the first and second chambers, resistance to fluid flow between the second chamber and the distal end of the catheter is less than the resistance to fluid flow between the second chamber and the first chamber, causing a rapid aspiration into the second chamber.

Abstract:

A methods of placing large bore aspiration catheters is disclosed. The method of removing a vascular obstruction includes the steps of transvascularly advancing a distal end of an aspiration catheter into proximity with an obstruction, activating a low flow, detection mode of aspiration through the catheter, and thereafter activating a momentary control to activate a high flow, aspiration mode of operation and draw obstructive material into the distal end of the access catheter.

Abstract:

A split dilator aspiration system is disclosed. The system includes a catheter, having an elongate, flexible tubular body with a proximal end, a distal end, a side wall defining a central lumen, and a handle on the proximal end. A dilator is advanceable through the central lumen, the dilator having an elongate body, cannulated to receive a guidewire, and an axially extending split along at least a portion of the elongate body, configured to allow removal of a portion of the dilator laterally from the guidewire.
