20110184449 | MARKER DELIVERY DEVICE WITH OBTURATOR - A marker delivery device includes an obturator having an elongated shaft, an internal lumen, a proximal end, and a substantially sealed distal end. The substantially sealed distal end is formed of a penetrable membrane. A marker delivery tube is configured to be slidably disposed within the internal lumen of the obturator. The marker delivery tube has a marker delivery lumen, a proximal end, and a distal tip. The marker delivery lumen is configured to contain one or more tissue markers. The distal tip is configured to puncture the penetrable membrane of the substantially sealed distal end of the obturator to form a passage through which the distal tip extends to facilitate delivery of the one or more tissue markers. | 07-28-2011 |

20140303667 | EMBOLIC PROTECTION DEVICE AND METHODS OF USE - Embolic protection devices for placement in an arterial system of a human and methods of using such devices. In one embodiment, the device includes a filter having a first filter section configured to be deployed along the ascending aorta and aortic arch, a tapered second filter section extending proximally from the first filter section, and a proximal portion extending proximally from the second filter section. The second filter section is configured to be deployed along the descending aorta, and the proximal portion extends to a position below a renal artery. The embolic protection device can be configured to continuously filter the arterial system blood between a distal end of the first filter section to a position within the arterial system downstream of the renal artery. | 10-09-2014 |
20140343602 | EXPANDABLE OCCLUSION DEVICE AND METHODS - An occlusion device and method for occluding an undesirable passage through tissue, such as a septal defect, that provides an expandable cylinder or other structure that occludes the passage internally or by covering one or more openings to the passage. The occlusion device includes a wire lattice or mesh that expands from a contracted catheter-deliverable state to an expanded state that occludes the passage. The lattice or mesh has one or more layers, with layers that provide structural support to the device, and layers that provide a lattice braiding or pore sizes that promote further occlusion by a biological process, such as tissue ingrowth that further occludes the affected passage. | 11-20-2014 |
20150018859 | METHODS AND APPARATUS FOR TREATING PULMONARY EMBOLISM - A device and method for intravascular treatment of an embolism, and particularly a pulmonary embolism, is disclosed herein. One aspect of the present technology, for example, is directed toward a clot treatment device that includes a support member configured to extend through a delivery catheter and a plurality of clot engagement members positioned about the circumference of a distal portion of the support member. The individual clot engagement members can have a first portion and a second portion extending from the first portion, and the first portions can have a proximal region attached to the support member. In the deployed state, the individual second portions can extend from the distal region of one of the first portions and project radially outwardly relative to the support member in a curve that has a proximally extending section which defines a proximally facing concave portion. | 01-15-2015 |
20150018860 | METHODS AND APPARATUS FOR TREATING SMALL VESSEL THROMBOEMBOLISMS - A device and method for intravascular treatment of an embolism, and particularly an embolism within a small vessel, is disclosed herein. One aspect of the present technology, for example, is directed toward a clot treatment device that includes a support member configured to extend through a delivery catheter and a plurality of clot engagement members positioned about the circumference of a distal portion of the support member. The individual clot engagement members can have a first portion and a second portion extending from the first portion, and the first portions can have a proximal region attached to the support member. In the deployed state, the individual second portions can extend from the distal region of one of the first portions and project radially outwardly relative to the support member in a curve that has a proximally extending section which defines a proximally facing concave portion. | 01-15-2015 |
20150133989 | EXPANDABLE OCCLUSION DEVICES AND METHODS OF USE - An occlusion device and method for occluding an undesirable vascular structure, such as a septal defect or left atrial appendage. The occlusion device includes a lattice structure that expands from a contracted catheter-deliverable state to an expanded state that occludes the vascular structure. The lattice structure has one or more braided layers, with structural braided layers that provide structural support to the device, and occlusive layers that provide a lattice braiding or pore sizes that promote further occlusion by a biological process, such as tissue ingrowth that further occludes the affected vascular structure. | 05-14-2015 |
20150305756 | METHODS AND APPARATUS FOR TREATING EMBOLISM - A method and apparatus for treating a clot in the blood vessel of a patient, and particularly the treatment of a pulmonary embolism is disclosed. The treatment includes restoring flow through the clot followed by clot removal, either partially or substantially completely. The clot treatment device is expandable into the blood vessel and may contain radial extensions that assist in restoring flow as well as in removing clot material. | 10-29-2015 |
