  • Patent number: 11446045
    Abstract: A system for assisting in the retrieval of a clot from a vessel. The system can include an outer catheter and an inner catheter disposed in a lumen of the outer catheter. The inner catheter can include a distal end, a proximal end, a distal segment, a proximal segment, and a lumen extending proximal of the distal end and terminating at a transfer port at the proximal end of the distal segment. A seal is located on the outer surface of the inner catheter distal of the transfer port, the seal capable of sealing against the lumen of the outer catheter so that aspiration applied through the outer catheter is configured to be transferred to the inner catheter.

  • Publication number: 20210353317
    Abstract: A design bringing together mechanical thrombectomy and stenting for more efficient treatment of occlusions and stenotic lesions in the cerebral vasculature features a dual-layer setup. The outer layer consists of an expandable stent cage with large cell openings which can allow thrombus to pass through the openings into the inner expandable capture section layer. The clot capture section can be configured to grip and extract the occlusion. The outer cage is configured to be detached from the remainder of the device and left implanted as a stent to exert an outward radial force to support and/or dilate the region of stenosis. The device can have a distal fragment protection element to prevent the distal migration of elements liberated during the procedure.

  • Publication number: 20210298889
    Abstract: A system for treating tandem occlusions (e.g. a clot causing ischemic stroke downstream of a carotid lesion with plaque buildup) in the vasculature can have a carotid filter with a retrieval feature near the proximal end, a deployment system configured to engage the retrieval feature as the vascular filter is delivered intravascularly and disengage the retrieval feature when the filter is anchored in place, and an engagement system configured to engage the retrieval feature while the filter is anchored and retract the filter. The carotid filter can remain in place during the patient's recovery period following the ischemic stroke until a procedure to treat the remaining occlusion is completed.

  • Patent number: 11125354
    Abstract: An infusion set check valve assembly includes a self-contained housing that defines inlet ports and an outlet port. The assembly also includes at least one check valve disposed within the self-contained housing between the outlet channel and at least one of the inlet ports. The at least one check valve is configured to open for a first fluid to flow from a first inlet to a patient line via an outlet channel while a second fluid also flows from a second inlet to the patient line via the outlet channel. The at least one check valve closes to prevent the first fluid from flowing to the patient line via the outlet channel while the second fluid flows to the patient line.

  • Publication number: 20210275197
    Abstract: A system has an outer catheter and an inner aspirating clot retrieval catheter having an expansile distal tip for flow restriction, improved aspiration efficiency, and a large mouth into which a clot or other obstructions can be retrieved. The clot retrieval catheter can have a support tube proximal of the tip. The expansile tip can be a strut framework, and a flexible, low-modulus cover is disposed around at least a portion of the tip strut framework and the proximal support tube. The distal end of the tip can be encapsulated by a low-friction elastomeric lip for atraumatic contact with the walls of a blood vessel. The tip has a collapsed delivery configuration and expands radially into a deployed configuration. The tip strut framework, support tube, and cover can all have characteristics which enhance the deliverability of the clot retrieval catheter to the target.
