Abstract: 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.

Abstract: A medical device includes a scaffold crimped to a catheter having an expansion balloon. The scaffold is crimped to the balloon by a process that includes inflating the delivery balloon during a diameter reduction to improve scaffold retention and maintaining an inflated balloon during the diameter reduction and prior and subsequent dwell periods.

Abstract: 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.

Abstract: A device for positioning suture through tissue, the device including a proximal elongate member having a longitudinal axis, the proximal elongate member being configured to receive a needle, and a tissue locator disposed distal the proximal elongate member, the tissue locator being coupled to an elongate member extending through the proximal elongate member and including a leg with a needle receiving opening configured to accommodate the needle. Proximal movement of the elongate member compresses the tissue locator and folds the leg of the tissue locator, the leg transitioning from extending longitudinally to extending outwardly in relation to a position of the leg in a pre-compressed state.

Abstract: A guidewire for use in penetrating through complex and stenosed lesions. The distal tip of the guidewire has a roughened surface to increase frictional engagement with calcified and fibrous tissue to increase the penetration of the distal tip and the guidewire into and through the lesion and reduce the likelihood of deflection of the guidewire tip. The average surface roughness of the distal tip is in the range from 1 micron to 200 microns.

Abstract: The present disclosure is directed to a multi-segment device, such as an intravascular guide wire. The multi-segment device includes an elongate first portion comprising a first metallic material, an elongate second portion comprising a different metallic material, the first and second elongate portions being directly joined together end to end by a solid-state weld, and a heat affected zone surrounding an interface of the weld where the first and second portions are joined together, wherein the heat affected zone has an average thickness of less than about 0.20 mm.

Abstract: A torque device for gripping and manipulating a guidewire for advancing the guidewire into a patient's vascular system. The torque device is configured for single-handed use and can be opened for repositioning the torque device relative to the guidewire and closed for gripping the guidewire to prevent axial and rotational movement relative to the guidewire. The torque device grips the guidewire at multiple spaced apart locations on the guidewire.

Abstract: A closure system for closing an opening in tissue, the closure system including a closure device and a knot replacement device configured to position a suture lock on a suture. The closure device includes a housing, a needle actuation handle cooperating with the housing, a first hollow needle selectively movable by the needle actuation handle and operatively cooperating with a suture anchor frictionally engaged with a slot and a lumen of the first hollow needle and coupled to a suture. A portion of the suture anchor rests along an outer surface of the first hollow needle as the first hollow needle is advanced through tissue adjacent the opening.
