摘要： Retrieval of material from vessel lumens can be improved by electrically enhancing attachment of the material to the thrombectomy system. The system can include a catheter having a distal portion configured to be positioned adjacent to a thrombus in a blood vessel, an electrode disposed at the distal portion of the catheter, and an interventional element configured to be delivered through a lumen of the catheter. The electrode and the interventional element are each configured to be electrically coupled to an extracorporeal power supply.

摘要： An improved catheter device for selectively isolating and occluding a portion of the descending aorta and/or the iliac vasculature of a patient, including a guiding or isolating component on a distal end of an elongate hollow catheter shaft which is advanceable though the vascular system of the patient. The catheter shaft has a proximal portion that extends out from the patient and a distal portion adapted to be disposed within the vasculature of the patient. The guiding or isolating component as well as a plurality of expandable members are disposed on the distal portion. A number of expandable members are positioned on the catheter with dimensions and configured so that when expanded it rests within a target artery or vasculature to occlude blood flow. Other expandable members may be spaced apart from the isolating or fixation member and configured to selectively isolate and occlude blood flow through different portions of target arteries and other vasculature.

摘要： The present invention provides an improved vascular occlusion device having improved flexibility and retention of the type fabricated from braided tubular metal fabric having an expanded preset configuration and an elongated collapsed reduced diameter configuration for delivery through a catheter to a treatment site and shaped to create an occlusion of an abnormal opening in a body organ or vessel, the woven metal fabric having a memory property whereby the medical device tends to return to said expanded preset configuration when unconstrained. The device further including at least one disk portion adjacent a body cylindrical portion formed from the fabric and having a transition diameter between the disk and cylindrical portion, significantly smaller than the diameter of the disk and the diameter of the cylindrical portion.

摘要： Described herein are the use of fluid complex coacervates that produce solid adhesives in situ to anchor medical devices such as catheters in a blood vessel. The anchored devices permit the targeted delivery of bioactive agents. The anchored devices can perform as an embolic agent by reducing or preventing blood flow in the vessel. Additionally, the embolic produced from the solid adhesive produced in situ can also include one or more bioactive agents that can be released in a controlled manner.

摘要： Systems and methods are provided for treating conditions such as heart failure and/or pulmonary hypertension by at least partially occluding flow through the superior vena cava for an interval spanning multiple cardiac cycles. A catheter with an occlusion device is provided along with a controller that actuates a drive mechanism to provide at least partial occlusion of the patient's superior vena cava, which reduces cardiac filling pressures, and induces a favorable shift in the patient's Frank-Starling curve towards healthy heart functionality and improved cardiac performance. The system may include sensors to determine the degree of occlusion of the superior vena cava. The occlusion system may be used to reduce volume in a heart and facilitate a cardiac procedure. The occlusion system may be used to relieve an overloaded chamber during and/or after deploying a VAD.

摘要： A therapeutic agent delivery system includes a catheter, a vascular occluder, a pressure sensor system, and a pump system. The vascular occluder is provided at a distal end of the catheter. The pressure sensor system is provided to sense pressure at a distal end of a catheter lumen, and provides feedback to the pump system. The pump system is adapted to control a rate of infusion of a therapeutic agent through the catheter lumen based on the pressure sensed by the pressure sensor system. A method includes deploying the vascular occluder in a vessel, and then sensing a pressure in the vessel. The therapeutic agent is infused into the vessel at a flow rate based on the sensed pressure in the vessel.

摘要： A catheter system can include a tubular body, and at least one of a targeting system coupled to the tubular body, an expandable member, or a fluid injection port. A method of identifying a bifurcation can include inserting a catheter system into a first vessel, positioning the catheter system at a first location, expanding an expandable member to occlude the first vessel, delivering contrast material so the contrast material pooling proximate to the expandable member, and reviewing a shape of the contrast material in the first vessel under fluoroscopy.

摘要： A method of constructing a detachment system for delivering an implantable medical device to a target location of a body vessel is presented. The method includes forming a compressible portion on a distal tube, engaging an implantable medical device with an engagement system, extending the engagement system through the distal tube such that the implantable medical device is distal of a distal end of the distal tube, applying a force to the engagement system to compress the compressible portion to a compressed state, fixing the engagement system to the distal tube to maintain the compressed state of the compressible portion, and joining a proximal end of the distal tube to a distal end of a proximal tube. The engagement system can include a loop wire that is fixed to the distal tube and engages the medical device.
