Percutaneous vascular surgical system and method
The present invention provides a percutaneous vascular surgical system for performing endovascular/neurovascular interventions, the system incorporating a sheath having a proximal end and a distal end and defining a main lumen extending between the proximal and distal ends, an auxiliary lumen also defined by the sheath, a reversibly inflatable balloon located about the sheath adjacent the distal end and in fluid communication with the auxiliary lumen, a syringe selectively connectable to the main lumen to create suction through the main lumen, and a vessel closure device for the closure of the arteriotomy, the surgical system and method of the invention having utility in a large number of percutaneous vascular procedures such as carotid artery stenosis or neurovascular interventions and enabling four procedures to be performed with one system, being percutaneous access, emboli removal, flow reversal and arteriotomy closure.
Electrophysiology mapping and visualization system
Electrophysiology mapping and visualization systems are described herein where such devices may be used to visualize tissue regions as well as map the electrophysiological activity of the tissue. Such a system may include a deployment catheter and an attached hood deployable into an expanded configuration. In use, the imaging hood is placed against or adjacent to a region of tissue to be imaged in a body lumen that is normally filled with an opaque bodily fluid such as blood. A translucent or transparent fluid, such as saline, can be pumped into the imaging hood until the fluid displaces any blood, thereby leaving a clear region of tissue to be imaged via an imaging element in the deployment catheter. A position of the catheter and/or hood may be tracked and the hood may also be used to detect the electrophysiological activity of the visualized tissue for mapping.
Thrombectomy systems and devices and methods of using the same
Thrombectomy systems and devices and methods of using the same. In an exemplary embodiment of a thrombectomy system of the present disclosure, the thrombectomy system comprises a thrombectomy sheath, comprising a circumferential outer wall reinforced with a reinforcement, configured as an elongated tube having a lumen therethrough; and a sonovisible element positioned at or near a distal end of the circumferential outer wall; wherein the thrombectomy sheath is sized and shaped to be at least partially positioned within a vein proximal to a thrombus or other item within the vein and further configured to expand to contact the vein to secure the thrombectomy sheath within the vein; and wherein the lumen is sized and shaped to receive a device selected from the group consisting of a balloon catheter and a snare having a loop.
Catheter based retrieval device with proximal body having axial freedom of movement
Provided herein are methods and systems for the removal of anatomical occlusions, and an occlusion removal device comprising a first body adapted to be mounted to a delivery wire and releasably engaged to the delivery wire, wherein while engaged the first body remains fixed on the delivery wire and upon release moves axially along the delivery wire, and a second body adapted to be mounted to the delivery wire. A first proximal body may be oriented proximally to a second distal body. The proximal body and the distal body may be adapted to expand upon exiting a delivery catheter. The proximal body may be releasably engaged by a mechanically breakable connection or an electrolytically or heat disconnectable connection, the electrolytically disconnectable connection being broken upon an application of electric current to the electrolytically disconnectable connection.
CLOT REMOVAL METHODS AND DEVICES WITH MULTIPLE INDEPENDENTLY CONTROLLABLE ELEMENTS
A clot removal device for removal of an occlusion from a lumen in a patient's body is provided. The clot removal device has a lumen, an elongated member positioned within the lumen and extending axially from a proximal end to a distal end of the lumen, a handle attached to the proximal end of the lumen, a first expandable member positioned along a length of the elongated member, a second expandable member positioned along the length of the elongated member, wherein the second expandable member is distal to the first expandable member relative to the handle. The handle has at least one actuation mechanism and at least one of the following applies: a) the first expandable member is coupled to the at least one actuation mechanism and is configured to be moveable relative to the second expandable member upon manipulation of the at least one actuation mechanism; b) the first expandable member is configured to mechanically expand or contract by manipulating the at least one actuation mechanism; c) the second expandable member is coupled to the at least one actuation mechanism and is configured to be moveable relative to the first expandable member upon manipulation of the at least one actuation mechanism; or d) the second expandable member is configured to mechanically expand or contract by manipulating the at least one actuation mechanism.
INSTRUMENT AND METHODS FOR SURGICALLY CLOSING PERCUTANEOUS PUNCTURES
Methods for sealing a percutaneous puncture in a wall of a body passageway are disclosed herein. The methods include inserting a deployment instrument into the puncture via a toggle along the guidewire, and actuating the deployment instrument to move the first component and the second component relative to each other such that the toggle abuts the wall of the artery proximate the puncture to seal the puncture.
Catheter with Shock Wave Electrodes Aligned on Longitudinal Axis
A catheter that fits within a blood vessel wall includes electrodes aligned along a longitudinal axis of the catheter that produce unfocused shock waves that propagate radially toward the blood vessel wall for treatment.
ENDOVASCULAR DEVICES AND METHODS FOR EXPLOITING INTRAMURAL SPACE
The present disclosure is directed to a device. The device may include a distal shaft defining a central lumen and an orienting element comprising at least one inflatable member. Wherein a first portion of the orienting element extending from the shaft in a first direction and a second portion of the orienting element extending from the shaft in a second direction. Further, wherein the second direction is substantially opposite the first direction.
Clot removal device for deep vein thrombosis
The invention being disclosed describes a medical device for removal of a thrombus or clot in a vascular setting by using a rotational, expandable basket structure in combination with drug infusion, blood/particle aspiration and clot isolation by distal and proximal occlusion.
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.
