Method and apparatus for delivering a stent, including, but not limited to, a self expanding stent, into a body lumen. The apparatus comprises an outer tube having a proximal end and a distal end and sized to hold a stent therein in a radially constricted condition, an inner tube within the outer tube and having a proximal end and a distal end, and a holding element comprising one or more inflatable balloons carried on the inner tube at the location of the loaded stent. The balloon can be inflated prior to the procedure so that the balloon presses against the inner surface of the outer tube trapping the stent in its longitudinal position between the inner and outer tubes. Accordingly, the outer tube can be slid proximally to release the stent or distally to retract the stent back into the delivery device without the stent inadvertently sliding.

Method and apparatus for delivering a stent into a body lumen

A method and apparatus for inserting a self expanding stent into a delivery device and delivering the stent into a body lumen. The apparatus comprises an outer tube; an inner tube; a capturing element slidably mounted on the inner tube and including a foldable sleeve, a blocking element fixed to the inner tube adapted to block a stent from being inserted into the sleeve proximally of the blocking element and to block the capturing element from becoming situated distally of a predetermined point relative to said inner tube, the capturing element carried on the inner tube so that the distal end of the sleeve can extend beyond the distal end of the outer tube in an unfolded condition and be drawn into the outer tube by the blocking element. A stent having an end inserted into the sleeve is drawn into the outer tube, thereby becoming captured within the outer tube. The stent is deployed by inserting the delivery apparatus into a body lumen to position the distal end of the tube adjacent the stent deployment site and drawing the outer tube proximally relative to the stent, so as to release the stent from its radially constricted condition.

Stent delivery apparatus and method

Methods for attaching an axial filament to the body of a self expanding stent, the filament serving to enhance the radial self expanding force of the stent body. Also stents having enhanced radial self expansion characteristics.

A temporary cardiac pacing wire, or a similar device, includes a pair of flexible electrode wires extending conjointly from a distal end of the pacing wire to its proximal end, where two electrically conductive sections are located. The conductive sections are suitable for connection to a power source adapted to generate electrical signals for stimulating, pacing, sensing, monitoring or defibrillating the heart of a patient. One conductive section results from the distal end of a Keith-type needle that breaks away from the rest of the needle. The other conductive section is arranged at the free end of a third electrode wire which is movable independently of the other two electrode wires, thereby permitting its connection to the power source in a plug-like fashion.

Electrical connector for cardiac devices

A temporary cardiac pacing wire, or a similar device, includes an electrically conductive lead which is folded over on itself so as to be adapted for connection to a pacing or monitoring apparatus. In the case of a bipolar temporary cardiac pacing wire, flexible wires are employed having two elongated conductive sections at a proximal end. The conductive sections are suitable for connecting to a power source adapted to generate electrical signals for stimulating, pacing, sensing, monitoring or defibrillating the heart of a patient. One conductive section results from the distal end of a Keith-type needle that breaks away from the rest of the needle. This section is suitable for directly connecting to the power source. The other conductive section is suitable for connecting to the power source when folded over on itself.

A device for sealing puncture wounds in blood vessels is open at one end and closed at the other end. The tube closure is generally flat and pivotable, and the tube region near the closed end is expandable. The device is initially contained in a sleeve, which is inserted through a cannula, so that the closed end is within the vessel to be sealed. After the cannula is removed, the closure is pivoted and the device withdrawn to a point where the closure abuts the puncture wound. After the sleeve is removed, the expandable region is expanded, so that the blood vessel wall around the puncture is sandwiched between the closure and the expanded region. The device prevents blood from seeping out of the punctured vessel during the healing process.
