Occlusive medical device system
An occlusive medical device system may include an elongate shaft having a distal strain relief portion and a lumen extending longitudinally through the elongate shaft, the elongate shaft including a plurality of retaining arms extending distally from the distal strain relief portion; an occlusive medical device including a proximal mounting portion fixed to an expandable occlusive element; and a release wire disposed within the lumen of the elongate shaft. The plurality of retaining arms may extend into the proximal mounting portion. The release wire may be configured to engage the plurality of retaining arms in a distal engagement position, thereby urging the plurality of retaining arms radially outward into releasable engagement with the proximal mounting portion. When the release wire is in a proximal released position, the plurality of retaining arms is deflectable radially inward to disengage from the proximal mounting portion.
Vascular occlusion and drug delivery devices, systems, and methods
Embodiments of the present disclosure comprise occlusion and drug delivery devices and methods. One aspect of the disclosure comprises a drug delivery device comprising an inner expansion member and an outer drug delivery component. Another aspect of the disclosure comprises bioabsorbable, lumen-occluding implants.
PATULOUS EUSTACHIAN TUBE STENT
A system effectively narrows a patulous Eustachian tube (ET) of a patient with a guide catheter, instrument, and insert. The guide catheter includes a shaft, a lumen and a distal end configured to provide access the ET when the guide catheter is inserted into a head of the patient. The instrument comprises a shaft. The insert comprises a body configured to radially expand and retract between a non-expanded state and an expanded state. The insert is sized and shaped to be received within the first lumen when in the non-expanded state and is operable to expand to the expanded state to substantially reduce an effective diameter of the ET.
DEVICES, SYSTEMS, AND METHODS FOR TREATING THE LEFT ATRIAL APPENDAGE
Disclosed are embodiments of a device for occluding a left atrial appendage (LAA) and other cavities or openings within a body. Some embodiments of the device can include an implant configured to be deployed within the LAA or other cavity, configured to be expanded or moved against a wall portion of the LAA or other cavity, and configured to twist at least a portion of the LAA or other cavity when the implant is rotated. Thereafter, one or more securing elements, staples, sutures, or other fasteners can be implanted in the gathered tissue to hold the tissue in the gathered state, thereby occluding the opening of the LAA or other cavity. In some embodiments, the opening of the LAA or other cavity can be occluded by elongating or otherwise reshaping the opening using an implant device, and securing the opening in the occluded state.
DEVICES AND METHODS FOR EXCLUDING THE LEFT ATRIAL APPENDAGE
Devices and methods are described for occluding the left atrial appendage (LAA) to exclude the LAA from blood flow to prevent blood from clotting within the LAA and subsequently embolizing, particularly in patients with atrial fibrillation. An implant is delivered via transcatheter delivery into the LAA. The implant includes a conformable structure comprising a foam body and internal support. The support includes anchors that penetrate the foam body and anchor the implant to the walls of the LAA. The implant provides compliance such that it conforms to the native configuration of the LAA.
Lacrimal Plug Inserter
A medical instrument and method is described for facilitating lacrimal occlusion. The instrument has two arms for holding a plug being inserted through the punctum, each arm having a distal end and a proximal end. Attached to the proximal end of the arms is a dilator oriented in the opposite direction along the longitudinal axis of the instrument. The instrument is conveniently rotated in the hand of the practitioner to alternately present the functioning end of the instrument as either the distal end of the arms (for holding a plug) or the distal end of the dilator (for enlarging the punctum prior to attempting to inserting the plug). The instrument has a means for moving the two arms near to each other and away from each, and a means for holding the two arms near to each other without requiring closing pressure applied by the practitioner.
DEVICE AND METHOD FOR ARTIFICIAL INSEMINATION
The medical device has a shield and an arm secured to the shield at one end and extending outwardly from the shield. The arm is inserted into the cervical canal of a patient and the shield covers the external os of the patient. By inserting the medical device into a patients cervical canal prior to insemination and leaving the device in place after insemination, a physical barrier that holds a semen sample within the cervical canal and prevents leakage from the cervical canal back into the vaginal cavity is established. The device may have a bore extending through the device for a catheter to pass through. The bore has a valve to allow passage of the catheter and prevent backflow of semen. The arm may have a plurality of longitudinal ridges, circumferential ridges, or circumferential barbs to help keep the device in place.

In some embodiments, the opening of the LAA or other cavity can be occluded by elongating or otherwise reshaping the opening using an implant device, and securing the opening in the occluded state.
DEVICES AND METHODS FOR EXCLUDING THE LEFT ATRIAL APPENDAGE
Systems, devices and methods for occluding the left atrial appendage (LAA). The device excludes the LAA from blood flow. The implantable device is delivered via transcatheter delivery into the LAA and secured within the LAA. The implant comprises an expandable and compliant frame and an expandable and conformable tubular foam body. A delivery and tether retraction system includes a handle for controlling a pusher and tether. The pusher may be moved a distance away from the implant without changing the orientation of the implant, while the tether is still attached to the implant. Severing the tether and proximally retracting a control on the hand piece by a distance causes the severed end to advance distally by at least about twice that distance. A loader includes a conical portion with guides and a reservoir for submerging the foam prior to loading and delivery.
