A balloon dilation catheter includes a substantially rigid inner guide member and a movable shaft coupled to a balloon that is slidably mounted on the substantially rigid inner guide member. To treat a sinus cavity of a subject using the balloon dilation the substantially rigid inner guide member is advanced into a drainage pathway of the sinus (e.g., frontal recess) of the subject via a nasal passageway. The shaft and balloon are advanced in a distal direction over the substantially rigid inner guide member to place the balloon in the drainage pathway. The balloon is inflated to expand or otherwise remodel the drainage pathway.

A handle apparatus comprising detachable hardware and void regions or attachment devices that accommodate the shape of surgical devices and imaging units such that the device is held securely and mechanically fixed to the imaging unit within the handle assembly.

A medical device for the treatment of a sinus opening includes a handle, a grooming sheath, a rail, a guide wire, a balloon catheter and a balloon catheter movement mechanism. The handle has a proximal end, a distal end and a longitudinal axis along the length of the handle. The grooming sheath has a distal end and a proximal end with the proximal end of the grooming sheath being attached to the distal end of the handle. The rail has a distal end and a proximal end and disposed partially within the grooming sheath to define an annular lumen is between the rail and the grooming sheath. The guide wire operatively extends from the distal end of the rail and the balloon catheter is disposed at least partially in the handle and annular lumen. The balloon catheter movement mechanism operatively disposed on the handle and configured for advancement and retraction of the balloon catheter through both the handle and the annular lumen and along both the rail and guide wire by user operation of the balloon catheter movement mechanism. A method for treating a sinus opening includes inserting a medical device for the treatment of a sinus opening partially into a patient's anatomy and then positioning a guide wire operatively extending from a rail of a medical device into a sinus opening of the patient. The method further includes advancing a balloon catheter from an annular lumen of the medical device and along both the rail of the medical device and the guide wire. The method also includes treating the sinus opening via inflation of the balloon catheter. In the method, the annular lumen is between the rail and a grooming sheath of the medical device and the advancing is accomplished via user operation of a balloon catheter movement mechanism of the medical device.

A closed-system urinary catheter with a low viscosity gel lubrication is disclosed. The system has an uncoated catheter, but a hydrophilic coated catheter could be used. The low viscosity lubricating gel within the sachet uniformly coats the catheter when the sachet is ruptured just prior to use. A low viscosity lubrication gel could alternatively be place in the area inside the sheath and external to the catheter. Therefore, the variability that occurs with a hydrophilic catheter or the areas of a non-lubricated catheter with the higher viscosity gel catheters is avoided.

A medical assistance device capable of improving handling or an operation of a medical device. The medical assistance device is connected to the medical device which is inserted into a biological lumen and is used in a procedure in the biological lumen. The medical assistance device includes a support, a winding unit which is rotatably provided about a support shaft with respect to the support and winds the medical device, and a connection section which is provided in the winding unit and is connected to an end portion of the medical device.

A guide catheter extension, having a push member having a proximal end and a distal end; a tube frame coupled to the distal end of the push member, the tube frame defining a lumen having a diameter sufficient to receive an interventional vascular device therethrough; and an inflatable element coupled to the tube frame, wherein the inflatable element is expandable into the lumen.

A medical device including a handle body having a proximal end and a distal end, a spool on the handle body and to move between the distal end and the proximal end of the handle body, a catheter extending from the distal end of the handle body, an actuator attached to the spool and extending through the catheter, such that the actuator is removably connected to one or more dispensable devices at a distal end of the catheter, a spool controller to prevent connection with another of the dispensable devices to the actuator after a predetermined number of dispensable devices have been dispensed by the medical device.

A catheter assembly includes a catheter, a catheter hub fixed to the catheter, an inner needle inserted through the catheter, and a grip that fixes and holds the inner needle. In addition, the catheter assembly includes a support structure portion that supports the outer side of the catheter. The support structure portion comes into contact with the catheter in an assembled state to deform at least one of the support structure portion and the catheter.

A urinary catheter conveying device includes a sleeve member, a conveying assembly and a controller. The sleeve member is for sleeving onto a glans of a penis and has a guiding hole to be registered with an external urethral orifice of the glans. The conveying assembly includes a casing removably mounted to the sleeve member, and a conveying mechanism for advancing the urinary catheter to the guiding hole such that the urinary catheter is inserted into the external urethral orifice. The controller controls the conveying mechanism to advance the urinary catheter to the guiding hole. A urinary catheterization system and a method of using the urinary catheterization system are also disclosed.

Motion generating devices for imparting motion to interventional devices to aid in the use of such interventional devices, and methods of making and using the same. An exemplary motion generating device of the present disclosure comprises at least one motion source, such as a motor, voice coil actuator, or the like, and a mating surface configured to engage an interventional device, wherein the motion generating device can impart multimodal vibrational and/or rotational movement, both independently and/or simultaneously, to the interventional device thereby aiding in the advancement of the interventional device through the vasculature of a patient.
