Abstract: The present invention features a filter canister device for filtering clot material from whole blood. The device includes an upper filter chamber and a lower filter chamber coupled to the upper filter chamber. The device further includes a coarse filter mesh disposed within the upper filter chamber, configured to capture the clot material from whole blood directed into the upper filter chamber, and a fine filter mesh disposed within the lower filter chamber, configured to filter the whole blood into filtered whole blood. The device further includes an inlet port fluidly coupled to the upper filter chamber, configured to accept the whole blood into the upper filter chamber. The device further includes an outlet port fluidly coupled to the lower filter chamber, configured to accept the filtered whole blood from the lower filter chamber and direct it to an external source.

Abstract: The present teachings provide devices and methods of engaging, capturing, and retrieving emboli. Specifically, one aspect of the present teachings provide a device comprising a generally cylindrical stent body, and a distal net. The stent body is configured to engage and capture emboli, while the distal net is configured to restrict blood flow, and capture embolic debris. Certain embodiments of the present teachings also provides devices and methods of engaging clots while better assist aspiration. Another aspect of the present teachings provide methods of use thereof to percutaneously remove blood clots with minimum risks.

Abstract: The present teachings provide a medical system for delivering and deploying a medical implant, and the method of using thereof. Specifically, one aspect of the present teachings provides a medical system having an implant with an engagement loop, and a delivery system having an engagement wire and an engagement mechanism. During implant delivery, the engagement wire engages the engagement loop of the implant. The engagement wire further interacts with the engagement mechanism in order to prevent unintended disengagement of the engagement loop from the engagement wire. The present teaching also provide an implant release mechanism that is configured to break away from the implant pusher shaft. Specially, one aspect of the present teaching provides that the implant release mechanism being of one unit with the implant pusher shaft. To release the implant, a clinician simply breaks away the implant release mechanism from the rest of the implant delivery system.

Abstract: The present teachings provide a catheter shaft design and configuration for use in the delivering and deploying a medical device, and aspiration removal of occlusion. Specifically, one aspect of the present teachings provides a catheter shaft design having a four-layer construction, an ultra-thin inner layer, a first coil middle layer, and a second braid middle layer, and an outer jacket layer. The first coil middle layer of the catheter shaft is made of a flat wire with width to thickness ratio of at least 2:1. The outer jacket layer of the catheter shaft is made of three different material with a soft durometer forming the distal portion of the outer jacket, a medium durometer material forming the middle/transitional portion of the outer jacket, and a stronger durometer material forming the proximal portion of the outer jacket.

Abstract: The present teachings provide a medical system for delivering and deploying a medical implant, and the method of using thereof. Specifically, one aspect of the present teachings provides a medical system having an implant with an engagement loop, and a delivery system having an engagement wire and an interface. During implant delivery, the engagement wire engages the engagement loop of the implant. The engagement wire further interacts with the interface in order to prevent unintended disengagement of the engagement loop from the engagement wire. Certain embodiment of the present teaching also includes an implant release control mechanism fixedly attaching to a proximal end of the engagement wire. During implant delivery, the implant release control mechanism attaches the proximal end of the delivery system. During implant deployment, the implant release control mechanism detaches the proximal end of the delivery system.
