摘要: Apparatus and methods for sealing a puncture through tissue includes an introducer sheath sized for introduction into a puncture, cartridge sized for insertion into the introducer carrying a sealant, and a locking element for coupling the introducer sheath to the cartridge. When the cartridge is advanced into the introducer sheath, the locking element couples the introducer sheath to the cartridge such that subsequent retraction of the cartridge causes the introducer sheath to retract, thereby deploying the sealant from the cartridge within the puncture beyond the introducer sheath.

摘要: Apparatus and methods are provided for delivering fluid into a body lumen during a medical procedure. A distal end of an apparatus may be introduced into a body lumen, and a valve on the distal end may be opened to deliver fluid through a first lumen into the body lumen, e.g., contrast and/or other diagnostic or therapeutic agents. The valve may be closed, and a procedure may be performed within the body lumen, e.g., using a treatment element carried on the distal end. For example, the treatment element may include a balloon that may be inflated when fluid is delivered through the first lumen with the valve closed. Optionally, a prosthesis, energy source, drug platform, and the like may be carried by the balloon for treating the body lumen. In various embodiments, the valve may be located proximal or distal to the treatment element.

摘要: An apparatus is provided that is operable in different modes to perform various functions for treating a body lumen. The apparatus includes a shaft including a proximal end, a distal end, a lumen extending therebetween, and a balloon on the distal end having an interior communicating with the lumen. The apparatus includes a valve on the distal end that selectively opens or closes an outlet communicating with the lumen. With the valve open, fluid introduced into the lumen exits the outlet into a body lumen. With the valve closed, fluid introduced into the lumen expands the balloon. The apparatus also includes an actuator for axially compressing the balloon, and a helical member extends between ends of the balloon interior that expands the balloon from a contracted condition to an expanded helical shape when the actuator is activated.

摘要: An occlusion device for sealing a puncture through tissue includes a tubular wire member having a proximal end, a distal end sized for insertion into the puncture, a lumen extending between the proximal and distal ends, a port adjacent the proximal end communicating with the lumen, and a balloon on the distal end. A source of fluid is connectable to the wire member for delivering fluid via the port into the lumen for expanding the balloon. A piston is movable axially within the wire member to allow fluid to be delivered into the lumen, to isolate the lumen, and to deliver fluid within the lumen into the balloon to expand the balloon.
