A method of using the catheter wherein at least a portion of the package is used as a drainage tube for the catheter. A package for an intermittent urinary catheter including a longitudinally compacted elastic package having a longitudinally extending receiving chamber containing a lubricating medium. The package having two longitudinal ends that may be removed to open the package and enable conversion of the package from a compacted state to an extended state. A method of using the package as a clean handling sleeve through which an intermittent urinary catheter may be passed to coat it with a lubricating medium.
INTRODUCER SHEATH AND INTRODUCER
An introducer sheath is disclosed, which includes a tube body that is percutaneously inserted into a body lumen; and a hub that is connected to a proximal portion of the tube body. The tube body contains a polyvinylidene fluoride resin, a ratio of a thickness to an inner diameter of the tube body is 1/16 or lower, and a ration of a kink radius to an outer diameter of the tube body is 9.5 or lower.
Coated Vaso-Occlusive Device and Methods for Treatment of Aneurysms
A method is described herein for the treatment of intracranial aneurysms. The method comprises inserting into an aneurysm an embolism coil coated with a polymeric coating comprising a genipin, such as genipin or a derivative thereof, thereby increasing the stability of clots within the aneurysm. According to one example, the coating is a poly(L-lactide-co-glycolide) (PLGA) is used to release genipin to crosslink fibrin clots thereby creating more stable occlusions. Increased clotting can improve segregation of the weakened portion of the blood vessel from the rest of the vasculature and reduce the risk of recurrence.
METHOD FOR MANUFACTURING A STEERABLE INSTRUMENT AND SUCH STEERABLE INSTRUMENT
Disclosed is a method for manufacturing a steerable instrument for endoscopic and/or invasive type applications, the instrument including an elongated tubular body having a proximal end part, a distal end part and an intermediate part between proximal and distal end parts, the proximal end part having at least one actuation proximal zone. The distal end part has at least one flexible distal zone, and the elongated tubular body is configured such that a movement of an actuation proximal zone is transferred to a corresponding flexible distal zone for a corresponding movement thereof. The elongated tubular body includes an inner, outer, and intermediate cylindrical elements having longitudinal elements between the inner and outer cylindrical elements. Inner, outer and intermediate cylindrical elements are coupled so movement of an actuation proximal zone is transferred by the longitudinal elements of one of the intermediate cylindrical elements to a corresponding flexible distal zone.
CATHETER TIP ASSEMBLED WITH A SPRING
A catheter tip having a spring element that imparts longitudinal flexibility, pushability and radial rigidity to the catheter tip, thereby improving deliverability, is provided. The spring element also provides radial support to the distal edge of the catheter tip. The spring element may taper distally, but may have a substantially constant inner luminal diameter. The spring element may be partially covered or embedded, leaving its distal end exposed. The spring element may also include spaced coils in a proximal region. The apparatus may be used with any interventional catheter system, but is particularly suitable for use with balloon-expandable stent systems and balloon-angioplasty systems, where flexibility of the catheter tip and minimal flaring of the distal edge of the catheter tip is desirable.
Apparatus and methods for assisted breathing by transvascular nerve stimulation
A catheter may include electrodes for transvascular nerve stimulation. The electrodes may be positioned within lumens of the catheter and aligned with apertures in the outer wall of the catheter. The electrodes may produce focused electrical fields for stimulation of one or more nerves. In one embodiment, the catheter may include a set of proximal electrodes and a set of distal electrodes, and the proximal electrodes may stimulate a patient's left phrenic nerve and the distal electrodes may stimulate a patient's right phrenic nerve.

A FOLDING DEVICE TO ASSIST IN SELF INSERTION OF A CATHETER TUBE INTO THE URETHRAL ORIFICE OF WOMEN
The present invention is a folding urethral catheter tube insertion device for women, abbreviated to: FUCID. The device facilitates easy finding of the location of the external urethral orifice in women and assists in the self insertion of a catheter tube into the urethra orifice while widening the orifice. Once inserted, user is able to disconnect the device from her body while maintaining the catheter tube in the urethra tract. The FUCID is typically produced as a single entity product and is typically produced by injection cast molding technology of a semi-rigid material. The FUCID folds to a compact, small size configuration, that is suitable and convenient to carry around in a small purse or small bag. The folded configuration of the FUCID is easily and simply unfolded to a ready-for-deployment configuration. The device is is constructed of: a vaginal insertion portion, abbreviated to VIP, a hollow funnel shaped tube guiding channel portion, abbreviated to TGCP, and a bridging plate between the two portions. The bridging plate is connected in a fixed connection of approximately 90 degrees to the widen side of TGCP and is connected to the VIP by a flexible hinge connection. Flexible wing curved bars protrude from the TGCP above the plain of the connected bridging plate. In its folded configuration of the FUCID, the VIP is folded to be in an approximate spatial parallel configuration with TGCP. In the FUCID unfolded configuration, the VIP is folded to be in an approximate aligned spatial configuration with FUCID. In deploying the FUCID, the TGCP aligned VIP is inserted into the vagina while positioning the opening of the wide side of TGCP over the uretheral orifice of the patient. The TGCP is pushed towards the body of the patient, causing the flexible wing curved bars to come into contact with the skin surrounding the uretheral orifice and to widen the orifice opening. With orifice openened the catheter tube is inserted through the TGCP.
Medical device package with twist-off cap
A package for a medical device such as an intermittent catheter has a case with open and closed ends. A hinge connects a cap to the case to permit movement of the cap between open and closed positions. A seal connected to one of the cap and case is engageable with the other to maintain a sterile environment inside the package. The seal can be repeatedly made and broken whenever the user closes or opens the cap. The case includes a pair of slots at the open end. A pair of latches is formed in the cap. The latches fit into the slots to prevent lateral forces from distorting the cap when the cap is closed. A first use indication label spans a depression in the outer contour of a closed cap and case, assuring visual confirmation of breach of the label upon first opening of the cap.
MEDICAL APPARATUS
A medical catheter that includes an elongate main tube, the tube having an outer wall that surrounds an internal passage, branch tubes having an outer wall connected to the outer wall of the main tube which extend outward from the main tube in different respective directions and have one or more apertures passing through their outer wall to their internal passage to permit fluid to pass through the branch tubes and into the main tube in use. The branch tubes are arranged to be able to move towards each other to permit location of the catheter within the bore of a needle or needle-like apparatus and which return to their original outwards state when removed.
