摘要： An interventional system is used to treat a lesion in a target anatomy. The interventional system includes a balloon catheter and a guidewire. The balloon catheter includes a balloon coupled to a catheter shaft. The catheter shaft includes a guidewire lumen having a lumen diameter. The guidewire includes a coil tip coupled to a guidewire shaft at a proximal joint. A coil diameter of the coil tip at the proximal joint is larger than the lumen diameter of the catheter shaft. The interventional system can be used to access and treat the lesion in the target anatomy. Other embodiments are also described and claimed.

摘要： This invention is directed to an expandable stent for implantation in a body lumen, such as an artery, and a method for making it from a single length of tubing. The stent consists of a plurality of radially expandable cylindrical elements generally aligned on a common axis and interconnected by one or more links. A Y-shaped member is comprised of a U-shaped member and a link having a curved portion and a straight portion to improve the flexibility and thereby improve the fatigue performance of the Y-link junction.

摘要： Balloon catheter includes an outer shaft having a hypotube and a monolithic single-layer distal outer member, a balloon in fluid communication with an inflation lumen, and a monolithic inner tubular member having a guidewire lumen defined therethrough. The outer shaft has the inflation lumen defined therethrough. The monolithic single-layer distal outer member is necked to a reduced diameter along an entire length thereof. A proximal end of the monolithic single-layer distal outer member is coupled to the hypotube. A distal section of the hypotube comprises a skive defined by a first angled cut, an axial cut, and a second angled cut. The balloon has a proximal balloon shaft coupled to a distal end of the monolithic single-layer distal outer member. The monolithic inner tubular member extends distally from a proximal port in the monolithic single-layer distal outer member through the balloon to form a tip.

摘要： A guidewire for use in intravascular procedures has an inner coil that is radiopaque and an outer coil that is non-radiopaque at the distal end of the guidewire. The radiopaque inner coil is visible under fluoroscopy so that the physician can monitor the location of the distal end of the guidewire during a procedure. The inner coil and the outer coil can be formed from a single wire or a multi-filar wire. The inner coil and the outer coil can have any of the following cross-sections for enhanced torquability: I-beam; vertical rectangular; vertical ellipse; square; peanut shape; vertical hexagonal; horizontal hexagonal; and horizontal ellipse.

摘要： A method and apparatus for positioning a locator. The method includes inserting a tissue locator through an opening in a tissue wall, and advancing an engagement member to move a portion of the first arm from a first position to a second position that is separated from a longitudinal axis of the tissue locator by a greater distance than the first position.

摘要： Shapeable guide wire devices and methods for their manufacture. Guide wire devices include an elongate shaft member having a shapeable distal end section that is formed from a linear pseudoelastic nickel-titanium (Ni—Ti) alloy that has linear pseudoelastic behavior without a phase transformation or onset of stress-induced martensite. Linear pseudoelastic Ni—Ti alloy, which is distinct from non-linear pseudoelastic (i.e., superelastic) Ni—Ti alloy, is highly durable, corrosion resistant, and has high stiffness. The shapeable distal end section is shapeable by a user to facilitate guiding the guide wire through tortuous anatomy. In addition, linear pseudoelastic Ni—Ti alloy is more durable tip material than other shapeable tip materials such as stainless steel.
