Provided is a medical tool for disconnection of a medical tubing connection comprising a resilient body forming a pair of open biased opposing jaws joined at a connected end; and gripping elements on an inside surface of each opposing jaws near the connected end to grip the medical tubing when the opposing jaws are moved together, to allow disconnection of the medical tubing connection. Also provided is a use of the medical tool for disconnecting medical tubing connection and a method for disconnecting medical tubing connection using the medical tool.

In a catheter system and method for assembly thereof, one end of a catheter shaft is inserted into a connector for a handle, with the connector being generally tubular and having a channel extending longitudinally therethrough. At least a lengthwise segment of the channel is sized in transverse cross-section greater than an outer cross-section of the catheter shaft. The catheter shaft is inserted into the channel of the connector such that the catheter shaft is spaced from the connector within the lengthwise segment of the channel. Adhesive is directed through a port in the sidewall of the connector into the lengthwise segment of the channel to flow circumferentially about the catheter shaft within the channel. The adhesive is allowed to cure and the connector (with the catheter adhered thereto) is retained on the handle.

Torque devices for use with intravascular devices and associated systems and methods are disclosed. In some embodiments, a torque device for use with an intravascular device includes a first component having a body defining a tapered opening for receiving a proximal portion of the intravascular device, a first arm extending from the body, and a second arm extending from the body; and a second component movably coupled to the first component, wherein the second component is movable relative to the first component between an open position where the torque device is configured to slidably receive the proximal portion of the flexible elongate member between the first and second arms of the first component and a closed position where the torque device fixedly engages the proximal portion of the flexible elongate member between first and second arms of the first component.

The present invention relates to a guiding needle for a suction tube, which is for increasing accuracy and preventing medical accidents by enabling an operator to accurately recognize the bent direction of the needle and to stably hold the needle by means of a handle portion formed inside the rear end of the needle connected to a tube or by means of a separate fixing handle coupled to the inside of the rear end of the needle. In other words, the present invention relates to a needle having the rear end thereof coupled to one end of a tube connected to a drainage container for discharging body blood of a patient, wherein the needle has a coupling part formed inside the rear end thereof and comprises a fixing handle detachably coupled to the coupling part.

Devices and methods of treating fluid retention caused by congestive heart failure or other conditions resulting in edema, lymphoedema, or significant fluid retention (e.g., deep vein thrombosis, cellulitis, venous stasis insufficiency, or damage to the lymphatic network) are described. Specifically, a treatment device is used to create a passage or cannula between the lymphatic system (or other area of the body) and an external drainage device. This device can be only temporarily located in the patient or can be implanted within the patient for longer periods of time. The physician can safely and reliably remove excess fluid from the body via the device and optionally inject other treatment agents.

A delivery system for placing a gastrointestinal device in a mammalian gastrointestinal tract comprises a container assembly; a gastrointestinal implant device that includes proximal and distal ends stored within the container assembly, the proximal end including an anchor and the distal end including a sleeve, coupled to the anchor and folded into the container assembly; and an inner extension to draw a portion of the sleeve from the anchor and from the container assembly as the anchor is retained therein. The inner extension comprises an atraumatic tip, such as a ball, that includes a guidewire rail. Further, a handle is provided that retains or captures an inner catheter within the handle. Within the handle is an elongated element that surrounds a portion of the catheter. A button on a side of the handle is configured to cause engagement of the catheter via the element when the button is depressed.

The present invention provides a guidewire adjuster and a delivery-system control handle provided with the guidewire adjuster. The guidewire adjuster includes a support mechanism which has a lumen for a guidewire to extend therethrough; and a driving mechanism for driving the guidewire to move back and forth in the lumen. The guidewire adjuster is able to drive the guidewire to move with respect to a sheath of the delivery system. The support mechanism is connected to the control handle of the delivery system and forms a lumen for accommodating the guidewire. A proximal end of the sheath together with the stent can be driven to move upwardly, due to the relative movement between the guidewire and the sheath of the delivery system. Therefore, the position of the stent can be adjusted by advancing the guidewire forward when the stent has been deployed at a lower position than expected.

A catheter with a distal end that rotates through the conversion of linear motion to rotational motion, thus the distal end may be rotated without longitudinally advancing or retracting the distal end. The catheter includes a tube with a single helix or a dual chirality helix cut into the tube, a distal end segment, means for linear displacement of the helix, and means for coupling the junction point of the helix to the distal segment.

A catheter insertion device which employs back-and-forth longitudinal axial movement to advance the catheter by the cooperative interface of an incline ramp and a decline ramp with a split gripping mechanism is described.
