  • Publication number: 20190175879
    Abstract: An intravascular catheter device includes a handle assembly, an inner member which accommodates a guide wire, an outer member disposed about the inner member, and a balloon. A proximal end of the balloon is attached to a distal end of the outer member. The balloon surrounds a portion of the inner member and the distal end of the balloon is attached to a distal end of the inner member. A sheath is selectively disposed about, and adapted for movement relative to, the balloon. A clamp at the handle assembly selectively secures the outer member at a number of positions relative to the sheath to selectively expose a variable portion of the balloon for movement into an inflated state. A balloon recapture device is located at a distal end of the sheath and aids the balloon in reentering the sheath following deployment.

  • Patent number: 10315014
    Abstract: An intravascular balloon catheter device is disclosed having an inner member, an outer member disposed about the inner member and further comprising a balloon. A sheath is disposed about the outer member that moves relative to the balloon so as to selectively expose some or all of the balloon for inflation. A clamp may be used to selectively secure the sheath at a desired position relative to the balloon. A balloon recapture element may permit incremental adjustment to the balloon length and facilitate balloon recapture.

  • Publication number: 20190083758
    Abstract: An intravascular balloon catheter device is disclosed having an inner member, an outer member disposed about the inner member and further comprising a balloon. A sheath is disposed about the outer member that moves relative to the balloon so as to selectively expose a first portion of the balloon for inflation. A clamp may be used to selectively secure the sheath at a desired position relative to the balloon wherein the desired position is less than full retraction such that a second portion of the balloon remains within the sheath.

  • Publication number: 20180318564
    Abstract: An intravascular balloon catheter device includes an outer member disposed about an inner member. A balloon has a proximal portion which is connected to the outer member and a distal portion which is connected to the inner member. A sheath is disposed about the outer member and adapted for movement relative to the balloon. A coating with a therapeutic agent is provided on at least the distal portion of the balloon. The distal portion fits snugly into the sheath so as to provide a substantially watertight engagement therebetween when inside the sheath. The sheath is configured to prevent the proximal portion of the balloon from inflating to a diameter larger than the sheath.

  • Patent number: 10117735
    Abstract: An intravascular filter (10) has a main filter portion (12) and an anchor portion (14). The main filter portion is made up of a number of struts (16), which form a first and a second biodegradable filter sections (26,28). The first and the second biodegradable filter sections biodegrade at different rates. The anchor portion secures the filter within a blood vessel and also has a collar (32). The first and the second biodegradable portions may have a different thickness and may be comprised of different materials. The collar may be formed from a resiliently deformable material.

  • Publication number: 20180125525
    Abstract: An intravascular device is provided having a flexible catheter tube with an expandable portion located on an end thereof. The expandable portion has a plurality of struts capable of being moved between an expanded and a collapsed position. An incising element provided along at least a portion of one of the struts has a sharpened edge for creating an incision in atherosclerotic material located within a blood vessel and generating microparticles of the same when the expandable portion is in the expanded position.

  • Publication number: 20180125526
    Abstract: A method for performing balloon catheterization of a zone of attention is provided. An intravascular device has an expandable portion secured to a distal end of a catheter tube. The expandable portion has a number of struts, at least one having an incising element extending perpendicular therefrom. The intravascular device is placed within a person's vascular system and moved to the zone of attention where the expandable portion is expanded and manipulated along the zone of attention to score the atherosclerotic material located in the blood vessel. Subsequently, a balloon catheter device is moved to the zone of attention and inflated to compress or fragment the scored atherosclerotic material.

  • Patent number: 9615848
    Abstract: An intravascular catheter device is provided for use during a surgical procedure. The catheter device includes a catheter tube having an expandable portion with a plurality of struts each defining an outer surface. The expandable portion is operable between a closed position, wherein the expandable portion has a first diameter, and an opened position, wherein the expandable portion has a second diameter that is larger than the first diameter. An incising element is provided on the outer surface of at least one of the struts. The incising element has a sharpened edge that extends outwardly in a radial direction from the outer surface of the strut for creating an incision in atherosclerotic material located within a blood vessel when the expandable portion is in the opened position.
