Abstract: A guidewire formed from drawn filled tubing having an inner core member encased in an outer layer. The inner core member is formed from a linear elastic or superelastic material and the outer layer is formed from a metal alloy such as 35N LT. A portion of the outer layer is ground down to form a feather edged joint between the outer layer and the inner core member.

Abstract: The present disclosure describes tissue gripping devices, systems, and methods for gripping mitral valve tissue during treatment of a mitral valve and while a tissue fixation device is implanted in the mitral valve. The tissue gripping device includes a flexible member and one or more tissue gripping members coupled to one or more arms of the flexible member. The flexible member is formed from a shape-memory material, such as nitinol, and the tissue gripping member(s) are formed from a material that is more rigid than the shape-memory material. The tissue gripping member(s) are attached to the flexible member by threading or looping suture lines around and/or through the tissue gripping member(s) and the flexible member and/or by applying a cover material to the tissue gripping device to hold the tissue gripping member(s) against the flexible member.

Abstract: The invention provides devices, systems and methods for tissue approximation and repair at treatment sites. The devices, systems and methods of the invention will find use in a variety of therapeutic procedures, including endovascular, minimally-invasive, and open surgical procedures, and can be used in various anatomical regions, including the abdomen, thorax, cardiovascular system, heart, intestinal tract, stomach, urinary tract, bladder, lung, and other organs, vessels, and tissues. The invention is particularly useful in those procedures requiring minimally-invasive or endovascular access to remote tissue locations, where the instruments utilized must negotiate long, narrow, and tortuous pathways to the treatment site. In addition, many of the devices and systems of the invention are adapted to be reversible and removable from the patient at any point without interference with or trauma to internal tissues.

Abstract: A medical device includes a catheter shaft extending along a longitudinal axis and having a shaft lumen. A balloon includes a proximal balloon end coupled to the catheter shaft, an interior in fluid communication with the shaft lumen, and a distal balloon end. A lead wire extends from a proximal wire end through the shaft lumen and the interior to a distal wire end. The lead wire includes a stepped portion between a proximal wire surface and a distal wire surface. The distal balloon end is axially fixed to the proximal wire surface. The proximal wire surface is narrower than the distal wire surface. Other embodiments are described and claimed.

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 suturing system including an elongate distal member and an elongate proximal member proximal the elongate distal member, the elongate proximal member having a lumen. A needle deployment actuator extends to the elongate distal member and is configured to initiate proximal movement of a needle toward an opening of the elongate proximal member. A guide is disposed within the elongate proximal member, a perimeter of the guide forming a plurality of needle receiving gaps that, when viewed in cross-section, are circumferentially spaced about the deployment actuator with a portion of the guide disposed between adjacent needle receiving gaps extending outwardly towards a wall of the lumen of the elongate proximal member.

Abstract: A device for closing an opening in a body lumen, the device having a first elongate member with a first lumen, a second elongate member distal the first elongate member, and a needle assembly slidably cooperating with the first elongate member to position a plurality of sutures within the lumen of the first elongate member. The needle assembly includes a needle base and a plurality of needle portions extending from the needle base. Slidable movement of the needle assembly in relation to the first elongate member locates the plurality of sutures selectively mounted to the needle assembly within the first lumen.
