Abstract: Adjustable catheter including an elongate tubular shaft having a proximal portion, a distal portion, and a length therebetween. The elongate tubular shaft has a guidewire lumen defined therein extending along at least the distal portion of elongate tubular member and further has at least one pressure lumen defined therein extending along at least a section of the length of the elongate tubular shaft. The at least one pressure lumen having a proximal end and a closed distal end. A fluid adaptor is in fluid communication with the at least one pressure lumen. The catheter has a stiffness profile and a flexibility profile along a length there of and at least one of the stiffness profile and the flexibility profile selectively adjustable upon introduction of a pressurizing fluid into the at least one pressure lumen.

Abstract: Methods and apparatuses for closure of vascular punctures or other openings in bodily tissues. The apparatuses and methods described herein are configured for everting a portion of tissue around a puncture site for wound closure on the external surface of the wound. For example, the tissue eversion apparatus may be configured for drawing up a portion of a vessel surrounding a venous or arterial puncture and orienting the inner surface of the vessel at least partially outward so that a closure element may be placed around the inverted region on the exterior surface of the vessel. In some embodiments, the devices are bioabsorbable.

Abstract: A closure device configured for closing an opening in a body lumen. The closure device may include a delivery sheath, a cleat, and one or more anchors. The cleat may be disposed within and move longitudinally with respect to the delivery sheath. The one or more anchors may be configured to engage tissue surrounding the body lumen opening and selectively couple to the cleat to obstruct and/or close the body lumen opening.

Abstract: An apparatus for occluding a venous or arterial puncture site is disclosed including a plug insertable within, or adjacent to, a puncture site in a wall of a body lumen. An insert is forced into an aperture within the plug to cause expansion thereof. The insert may be drawn into the aperture by applying tension to a line passing therethrough and secured to the insert. Barbs may secure to the plug to engage the wall of the body lumen or adjacent tissue tract. Elongate members passing through the wall of the plug may be forced outwardly into the wall of the body lumen or adjacent tissue as the insert is forced into the aperture.

Abstract: A tissue closure device includes a collapsible plug and an actuator. The plug has a surface extending between a proximal face and an opposing distal face. A lumen extends through the plug between the proximal and distal faces along a longitudinal axis. The plug is collapsible between a non-collapsed state in which the lumen is open and a collapsed state in which the lumen is closed. The actuator is configured to move the plug between the non-collapsed state and the collapsed state by being pulled proximally, such as through the lumen.
