  • Publication number: 20260090901
    Abstract: A stent delivery apparatus is disclosed and configured for selectively positioning a self-expanding stent relative to a target site. In at least one embodiment, a delivery mechanism is configured for being selectively positionable coaxially within and removably engageable with the stent. The delivery mechanism provides at least one self-expanding delivery sleeve, with each delivery sleeve providing a proximal end cap positioned at a proximal end of said delivery sleeve and a distal end cap positioned at an opposing distal end of said delivery sleeve. An engagement mechanism is positioned coaxially within said delivery sleeve and provides an elongate engagement shaft engaged with the proximal end cap and extending a distance toward the distal end cap, and an at least one stent catch positioned substantially on a distal end of the engagement shaft and configured for removable engagement with the stent.

  • Patent number: 10039912
    Abstract: An elongate medical device handle may comprise a body defining an interior, an exterior, and a connector port extending between the interior and the exterior and defining an axis. The connector port comprises a portion having a polygonal cross-section taken transverse to the axis. In an embodiment, the polygonal cross-section may comprise a star shape. In an embodiment, a connector, such as a fluid connector, may be secured in the connector port using an adhesive.

  • Patent number: 8734440
    Abstract: A catheter comprising a flexible tubing having a proximal end and a distal end. An electrode assembly is attached to the distal end of the flexible tubing. The electrode assembly includes an electrically conductive tip electrode and a coupler which is connected between the tip electrode and the distal end of the flexible tubing. The coupler and the tip electrode are coupled by an interlocking connection. A first magnet is at least partially housed in the coupler. A fluid lumen extends through the flexible tubing to the coupler. The fluid lumen extends completely through the first magnet and connects to at least one port formed in the electrode assembly. A second magnet is spaced from the electrode assembly along a longitudinal axis of the tubing. The first magnet and the second magnet are responsive to an external magnetic field to selectively position and guide the electrode assembly within a body of a patient.
