Alternative use for hydrogel intrasaccular occlusion device with vertically oriented reinforcement members for structural support
A device for endovascular treatment to ameliorate aneurysm recurrences by deploying a treatment mesh having a plurality of vertically oriented elongated support reinforcement elements that are substantially parallel and oriented upon a plane in communication with the mesh. Upon deployment, the array of distal ends of the support extensions and reinforcements are substantially oriented upon a plane, which plane is in substantially the same orientation as the opening of the aneurysm into which the device was deployed. The treatment mesh may incorporate a coating of hydrogel, optionally impregnated with pharmaceutical compounds.
PRE-LOADED INVERTING TRACTOR THROMBECTOMY APPARATUSES AND METHODS
Mechanical thrombectomy apparatuses including an inverting, rolling conveyor region (“tractor”) at the distal end that are configured to grab and remove thrombus material. In particular, described herein are mechanical thrombectomy apparatuses that are adapted to prevent premature deployment of the tractor, e.g., by including a tractor hold (e.g., a housing, a lock, a clamp, etc.) or the like to secure the outer end of the tractor against and/or relative to the elongate inversion support.
SYSTEMS FOR REMOTELY CONTROLLING ASPIRATION PATTERNS
An aspiration system includes a pump and a control system in communication with the pump. The control system includes a microcontroller, an antenna configured to receive a signal, and a pump control board in communication with the microcontroller. The antenna is in communication with the microcontroller. Upon receiving the signal, the pump control board operates the pump to create negative pressure according to the signal.
Endovascular balloon catheters and methods for use
A balloon catheter and methods for use are disclosed for endovascular procedures, e.g., performing a thrombectomy. In one embodiment, among others, the balloon catheter includes an elongated catheter body. At a distal end, the catheter body also includes an angled tip and a balloon adjacent to the angled tip. The balloon is inflatable to form an oblong shape.
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.
DEVICES AND METHODS FOR REMOVAL OF ACUTE BLOCKAGES FROM BLOOD VESSELS
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.
VIBRATION SYSTEM AND DEVICE FOR EXTRACTION OF A LEAD OF A CARDIAC IMPLANTABLE ELECTRONIC DEVICE
The present disclosure provides a lead locking device that is configured to be inserted into a lumen of a lead of a cardiac implantable electronic device (CIED), such as a lead of a pacemaker, and being locked at a selected position along the lumen for being retained there for allowing extraction of the lead and/or applying vibrations to the selected position. The lead locking device includes a deformable element that may deform by application of force thereon and the deformation thereof results in radial expansion thereof such that if it is disposed within a lumen of a lead, it presses against the walls of the lumen and applies force that retains the lead locking device in position. The deformable element may be configured for reversible deformation, namely that upon removal of the force that is applied thereon, it is reversed to a contracted, non-engaging state where its radial dimension is lower than the dimension of the lumen. The deformable element may be in the form of a metallic braid, a flexible rod or a wire, an inflatable member, a spring, a structural weakening portion in a body member, such as cuts or holes, allowing a portion of the body to expand, etc.
CLOT REMOVAL METHODS AND DEVICES WITH MULTIPLE INDEPENDENTLY CONTROLLABLE ELEMENTS
A retriever device for removal of unwanted material from a vessel in a patient's body comprising a retriever sub-system and an aspiration sub-system. The retriever sub-system comprising a delivery catheter and a delivery wire having first and second expandable bodies disposed thereon that are adapted to expand from a pre-expansion configuration to an expanded configuration. The second expandable body is further adapted to slidably translate along the delivery wire in a distal direction toward the first expandable body when the second expandable body is released from the delivery wire, whereby, when the first expandable body is disposed on a distal side of at least a first portion of the unwanted material in the vessel and the second expandable body is disposed on a proximal side of the first portion of the unwanted material, the first expandable body and the second expandable body surround and contain the first portion of the unwanted material between the first expandable body and the second expandable body. The aspiration sub-system is adapted to remove at least a second portion of the unwanted material from the vessel. The aspiration sub-system also includes a pressure sensor adapted to monitor internal vessel pressure proximate an internal region of the vessel.
INVERTING THROMBECTOMY APPARATUSES AND METHODS
Rolling tractor tube mechanical thrombectomy apparatuses that may be deployed from out of a catheter in situ are described herein. These apparatuses may be delivered out of a catheter from a collapsed delivery configuration within the catheter to a deployed configuration out of the catheter, in which the same catheter is re-inserted between a tubular tractor and an elongate puller. In particular, any of these methods and apparatuses may be adapted to work with a tractor tube having an open end that is biased open, including using an annular bias.
Apparatus and methods for treating obstructions within body lumens
An apparatus is provided that is operable in different modes to perform various functions for treating a body lumen. The apparatus includes a shaft including proximal and distal ends, a lumen extending there between, and a balloon on the distal end. The apparatus includes a valve on the distal end that selectively opens or closes an outlet communicating with the lumen. With the valve open, fluid introduced into the lumen exits the outlet into a body lumen. With the valve closed, fluid introduced into the lumen expands the balloon. The valve may be biased to be closed, e.g., by a spring element disposed within the balloon. Optionally, the apparatus also includes an actuator for expanding a helical member within the balloon interior, e.g., either before or after expanding the balloon, such that the helical member and balloon may adopt an expanded helical shape for removing material within a body lumen.
