摘要:
The invention provides a stent made from a material operable to perform a stent's desired therapeutic functions, and also made from a material that has a radiopacity that substantially preserves the appearance of the stent when the stent is viewed under a CT imaging beam. Such a stent can allow for follow-up of the stent and the surrounding blood-vessel on CT.

An embodiment of the present invention provides a kit of parts for use in a surgical procedure performed under image guidance, and particularly under real time image guidance. The kit includes a sterilized drape for use with the chosen imaging machine and which can be used to provide a sterile operating environment when the procedure is performed under the imaging beam. The kit also includes a needle holder that can keep the surgeon's hand away from the imaging beam. The needle holder is operable to hold a needle that is made from a material suitable for piercing tissue, but also substantially preserves the appearance of the needle when it is viewed under the imaging beam.

The invention relates to stent delivery system and method. A stent delivery system includes a self-expandable stent and a sheath configured to surround the stent in a compressed state. A catheter is adapted to deliver the stent and the sheath into a predetermined deployment site. A balloon is mounted on a tip of the catheter and is inflated to expand the stent. Upon deployment of the stent, the sheath is trapped between the stent and a vessel.

A cement delivery needle apparatus (20) and a method of flowing a bone cement through a vertebroplasty needle apparatus are provided. The cement delivery needle apparatus (20) includes a sheath (24) and a handle (26). The sheath (24) has an inlet (44) to receive a bone cement and an outlet (40) for expressing the cement into a vertebral body. The handle (26) extends from the sheath (24) and includes a vibration assembly (70) for agitating the cement. The method includes providing a bone cement source to the needle. The method further includes providing a vibration assembly associated with a handle of the needle, agitating the cement with the vibration assembly and injecting the cement through the sheath.

A bale splitter (1) for mounting on a front end loader arm of a tractor' comprises a support framework (5) having a plurality of tines (7) extending transversely therefrom for supporting a cylindrical wrapped bale (2). A pair of carrier arms (15) pivotally coupled to the support framework (5) carry a cutting blade (20) for splitting the bale (2) and for simultaneously cutting wrapping material of the bale (2). The cutting blade (20) is slightly spaced apart from the tines (7) for preventing cutting of the wrapping material (4) adjacent the tines (7) so that the wrapping material remains in one single integral piece after splitting of the bale (2). A grab (30) comprising jaws (32,33) is supported on the support framework (5) to abut the bale (2) when supported on the tines (7), and for gripping the wrapping material (4) prior to operation of the cutting blade (20) for cutting the bale (2). By tilting the bale splitter (1) the split bale is discharged and the wrapping material (4) still gripped by the grab (30) is thus separated from the split bale.

A method for augmenting bone is provided. In an embodiment, a bone cement is administered, typically directly to the affected bone, and a bone augmentation agent administered, via any suitable means including orally, nasally, transdermally. The bone augmentation agent is chosen to complement the bone cement, to thereby facilitate the integration of the bone cement into the natural bone which contacts the bone cement.

A shunt for draining cerebral spinal fluid from the brain is provided. In an embodiment, the shunt includes a master control unit that is located in the abdomen, which interconnects a ventricular catheter and a second catheter, typically located in the peritoneal cavity. In a specific embodiment, the master control unit includes a variety of ‘smart’ features including at least one access port to allow the injection of solutions for the prevention or removal of blockages in the catheter, and/or antibiotics. The access port can have other uses, such as allowing a point of access for physical navigation of a catheter or the like within the shunt, thereby providing another option for breaking-up blockages, and/or allowing an access point for repairing the shunt's components. Additionally, the master control unit includes a diagnostic unit that transmits, either wirelessly or through a wired connection via the access port, diagnostic information about the status of the patient and/or the shunt.
