  • Publication number: 20200030086
    Abstract: In some embodiments, a method includes delivering to a native valve annulus (e.g., a native mitral valve annulus) of a heart a prosthetic heart valve having a body expandable from a collapsed, delivery configuration to an expanded, deployed configuration. The method can further include, after the delivering, causing the prosthetic heart valve to move from the delivery configuration to the deployed configuration. With the prosthetic heart valve in its deployed configuration, an anchor can be delivered and secured to at least one of a fibrous trigone of the heart or an anterior native leaflet of the native valve. With the prosthetic heart valve disposed in the native valve annulus and in its deployed configuration, an anchoring tether can extending from the anchor can be secured to a wall of the heart to urge the anterior native leaflet towards the body of the prosthetic heart valve.

  • Patent number: 7115101
    Abstract: A guide wire including a lubricous distal portion and a less lubricous intermediate portion proximal of said distal portion. One guide wire provides a highly lubricous distal portion with a hydrophilic layer and a less lubricous intermediate portion with a hydrophobic layer. Another guide wire provides a lubricous distal portion with a polymer tip that is itself hydrophilic. Yet another guide wire provides a less lubricous intermediate portion using a stainless steel coil helically wound around the tapering intermediate portion. The coil is preferably coated with a hydrophobic coating such as PTFE or silicone. The coil can either abut the distal portion proximal end or extend into the distal portion interior.

  • Patent number: 6676590
    Abstract: A radiation source for inhibiting restenosis including a radiation delivery tube having a radioactive distal region, the tube being adapted to slide over a guide wire within a radiation delivery catheter. One tube has radioactive material incorporated into the tube wall material. Another tube has radioactive material secured to the tube surface. One radiation delivery balloon catheter includes a common inflation and radiation delivery lumen, the lumen being sealed distally and having a radiation source guide wire within the lumen. The lumen is sealed from contact with bodily fluids and is filled with inflation fluid during use. In use, the catheter balloon is advanced to a site to be treated, the balloon inflated, and the radioactive tube advanced over the radiation source guide wire within the lumen.

  • Patent number: 6471671
    Abstract: An inflation device such as a syringe is preloaded with gas (other than air) for inflation of balloon catheters. The syringe is lined with, or is packaged within, a low gas-permeability membrane to keep the stored gas from becoming contaminated with air. The physician using the syringe is able to determine whether air has infiltrated the syringe and contaminated the gas stored in the syringe.

  • Patent number: 6416457
    Abstract: A system for intravascular ionizing radiation therapy including a radiation device and a guide wire having radiopaque markers to facilitate precise repositioning of the radiation source along the length of the treatment site. The radiopaque markers are separated by a distance L, which corresponds to the distance between the 50% dose points in the dose fall-off regions. This produces partial dose overlap when the radioactive source is positioned in tandem adjacent each radiopaque marker. Preferably, only the dose fall-off regions overlap thereby providing more uniform and complete radiation exposure along the length of the treatment site.

  • Patent number: 6398708
    Abstract: A catheter capable of irradiating blood vessel walls to inhibit restenosis after angioplasty. Catheters are capable of simultaneous irradiation, angioplasty, and in some devices, drug infusion. Preferred catheters include a helical perfusion balloon having strand windings spaced apart when inflated and defining a perfusion lumen within. A tubular sheath over the helical strands and distal shaft region is used in some embodiments and defines an outer wall for the perfusion lumen. A spiral, inter-strand space is defined between the sheath outer wall and the blood vessel inner wall, providing a confined volume for controlled delivery of drugs to the vessel wall in conjunction with irradiation. A device having a radiation wire, distally closed-end tube is provided. A device having a radiation wire open ended tube terminating proximally of the perfusion lumen is also provided.
