  • 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: 10010380
    Abstract: Methods for localizing a biopsy site are disclosed. The method includes taking a tissue sample from a biopsy site and positioning a detectable, bioabsorbable element at the biopsy site at the time that the tissue sample was taken. The tissue sample is then tested. The biopsy site is then relocated by finding the bioabsorbable element. The bioabsorbable element may be made of collagen, gelatin, cellulose, polylactic acid, and/or polyglycolic acid. The detectable bioabsorbable element may be relocated using ultrasound or mammography. The bioabsorbable element may also swell upon contact with body fluid.

  • 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: 8292822
    Abstract: A biopsy localization device made according to the invention includes a bioresorbable element, such as a cellulose. The bioresorbable element preferably carries a radiopaque marker. The bioresorbable element preferably swells to fill the biopsied open region. The bioresorbable element and radiopaque marker permit the biopsy site to be relocated by various techniques, including mammography and ultrasound. In addition, the bioresorbable element can be used as a therapeutic tool for treatment of the diseased lesion and for hemostasis.
