    摘要: The disclosure pertains to magnetically retrievable vena cava filters having a low torque associated therewith when subjected to a strong external magnetic field and retrieval devices therefor. The vena cava filter may include a magnetically permeable sphere or a spherical dipole magnet located within the spherical cavity of the apical hub wherein the spherical dipole magnet is free to rotate about any of three mutually orthogonal axes. The retrieval device is capable of substantially containing the vena cava filter in a collapsed state and includes a magnetically active member capable of interacting with the vena cava filter. The retrieval device may optionally include a supplemental mechanical latch.

    摘要: A catheter includes a multiplicity of leads having exposed distal elements defining an anode and a cathode positionable relative to an outer wall of a renal artery. A power supply is configured to couple to the multiplicity of leads. The power supply generates a DC current that flows between the anode and cathode to create an acidic region at the anode sufficient to cause necrosis of perivascular renal nerve tissue in the vicinity of the anode, and to create a basic region at the cathode sufficient to cause necrosis of perivascular renal nerve tissue in the vicinity of the cathode. The catheter may be configured to deliver a biocompatible electrolytic fluid to each of the cathode and anode, thereby increasing an extent of perivascular renal nerve tissue ablation in the vicinity of the cathode and anode.

    摘要: A stent assembly includes a stent, a covering on at least a portion of the stent, and a string encircling at least a portion of the covering. The string is releasably engaged to the covering or stent or both the covering and the stent. The string can be adhered to the stent, or the stent assembly, to the covering of the stent assembly, or both the covering and the stent. The string can be wrapped around the stent or covering in an interwoven loop or knit pattern. The covering can be made to overlap a perforation in a body lumen such as an artery or blood vessel and prevent bleeding.
