Abstract: The releasable torque device obviates the need for removal of the wire introducer in order to torque or manipulate a vascular or other guide wire and/or catheter in a medical procedure, and further obviates the need to remove the torque device for wire and/or catheter introduction. The device may include a base cylinder and an inflation cylinder defining a variable fluid volume therebetween. As the inflation cylinder is pushed toward the base cylinder, the fluid is forced through a port in the inner wall of the inflation cylinder and between a tubular inner cylinder and an inflatable guide wire grip within the inner cylinder to squeeze the grip onto the guide wire passing axially therethrough. Alternatively, the device only has a central tube and an inflatable guide wire grip therein, using a remotely disposed fluid pump and reservoir supplying fluid to the tube and guide wire grip.

Abstract: A medical material delivery device includes a shaft having a lumen that receives a therapeutic agent, and can include a guide having a channel for receiving a medical instrument adapted for positioning in conjunction with a bodily part. An expandable member positioned in conjunction with the guide is adapted for communication with the bodily part and is arranged to burst open when the expandable member is disrupted by a disrupting mechanism to deliver the therapeutic agent to the bodily part. Further embodiments include a medical instrument and an expandable member in conjunction with the medical instrument to burst or leak to deliver a therapeutic agent. The medical material delivery device can include a bodily fluid locator attached with the device, as well as can include a second expandable member to inflate and deflate to localize a bodily part, with a first expandable member bursting to deliver a therapeutic agent.
