  • Patent number: 10335577
    Abstract: The present invention relates to a catheter apparatus with an anchoring device to stabilize the catheter tip when in use, such as when infusing, injecting, or delivering substances, devices or other catheters into a patient. The apparatus according to various embodiments deploys an anchoring device that stabilizes the catheter tip and enables adjustment of the blood flow during use.

  • Publication number: 20190159912
    Abstract: A novel temporary vascular scaffold is described. The temporary vascular scaffold is placed over an existing balloon catheter assembly, such as a commercially available balloon catheter assembly, and attached thereto. The temporary vascular scaffold is placed over the balloon of the catheter assembly. The balloon and the temporary vascular scaffold are expanded against a target region in the vessel wall. The temporary vascular scaffold causes the balloon expansion to be more gradual and well distributed over the outer surface of the balloon, reducing the risk of trauma. The balloon is then collapsed, leaving the temporary vascular scaffold to provide support to the vessel wall. While the vessel wall is propped open, the target region is infused with a diagnostic or therapeutic agent to diagnose or treat the target region.

  • Patent number: 9498604
    Abstract: A vessel-occluding medical device for the use in diagnosis and/or treatment of cardiovascular disease in the human body includes an outer tube, an inner tube slidably housed within the outer tube, and a tubular sleeve comprising a generally U-shaped, direction reversing region, which moves along the length of the tubular sleeve, to assume radially contracted and radially expanded state as the inner and outer tubes move between the first and second positions. When the tubular sleeve is in the radially expanded state, the inner portion of the tubular sleeve has a funnel-shaped surface and a longitudinally-extending opening to permit material to pass therethrough for receipt of material into the inner tube.

  • Publication number: 20150351770
    Abstract: An occlusion apparatus comprises inner and outer sheaths and an expandable flexible tubular sleeve. The occlusion apparatus is advanced to a target site in the blood vessel. A dilator having a soft, compressible tip may be advanced through a lumen of the inner sheath to facilitate the advancement of the occlusion apparatus. The sheaths are translated relative to one another to expand the flexible tubular sleeve to a funnel shape with a distal flush portion contacting the blood vessel inner wall and a proximal tapered portion. The proximal portion is fluid permeable so that blood can pass through to apply pressure on the vessel wall through the distal portion. A capture or traction device can be advanced out of the inner sheath lumen and retracted back therein to capture thrombus. The distal portion of the device may comprise an expandable mesh braid with a memory characteristic to limit expansion.

  • Patent number: 9114031
    Abstract: A method of treating a target site within a vascular channel of the body uses a catheter assembly having proximal and distal occluders which are positioned in occluding states at positions proximal and distal of a target site to define an occluded region therebetween. An agent is injected into the region. An intervention is performed at the target site while the vessel is occluded and the agent is in the region. The catheter assembly is removed from the channel. Intervention may include expanding a balloon within a temporary stent structure against the channel, collapsing balloon and then removing the collapsed balloon and stent structure from the channel. A balloon stent assembly comprises a catheter assembly, a temporary stent surrounding a balloon, the temporary stent placeable in a contracted state by the catheter assembly and in an expanded state by inflation of the balloon.

  • Patent number: 7232432
    Abstract: A particle-removing medical device includes an outer, hollow tube having a tube distal end and a porous braided structure having a distal part and a proximal part. Structure, housed within the tube and having a distal end positioned distally of the tube distal end, is used to move the braided structure from a contracted condition to an expanded condition by moving the distal ends of the tube and the structure towards one another. The braided structure is constructed to inhibit particles from moving completely through the braided structure when in the expanded condition.

  • Patent number: 6852097
    Abstract: A device and method to dissolve or eliminate blood clots from a patient relies upon a non-rapid moving mechanism to physically dissolve clots without damaging endothelium of the arteries and veins of a patient. In one embodiment, in addition to mechanical agitation of a clot, a thrombolytic agent is administered simultaneously with such agitation. Preferably, intermittent agitation is utilized over a prolonged period of time to effectuate clot removal.

  • Patent number: 6453582
    Abstract: A snowplow apparatus as adapted to attach to a vehicle having a ball hitch assembly. The snowplow apparatus has a blade assembly connected to an elongated drawbar. A frictionally activated elevating mechanism is operatively connected to the drawbar and moves between a vertical and non-vertical orientation depending upon whether elevation of the blade or contact with the blade and the ground is desired, respectively. A further aspect relates to a lateral stabilization device associated with the opposite end of the drawbar, such stabilization device coming into contact with static members operatively associated with a hitch ball such that lateral movement of the drawbar is substantially precluded due to the contact between the stabilization members and the static elements.
