Title: Delivery catheter and graft for aneurysm repair
Inventor: BROWN PETER S
IPC: A61F2/958
Filed: 1995-11-08
Abstract: This invention provides a graft delivery system and methods for its use comprising a prosthetic graft (12) secured to an expandable anchoring member, such as a stent (13), by a butt-joint attachment means (21) to minimize the system's profile. The delivery system employs a catheter (11) with a relatively small diameter shaft (14) for flexibility and a relatively large diameter (14) delivery base (17) for supporting expansion of the anchoring member. The butt-joint attachment means comprises any means suitable to secure the graft to the anchoring member when deployed within the patient's vasculature and allows the anchoring member and graft to expand during deployment. In a preferred embodiment, the delivery system is configured so that the expansion of the anchoring member pulls the distal end of the graft over the proximal end of the anchoring member and the final expansion of the anchoring member seals the distal end of the graft (12) between the proximal end of the anchoring member and the vessel (20). One preferred method of use is to deploy a second anchoring member (31) coaxially within the already deployed first anchoring member and graft assembly, overlapping at least the distal end of the graft in order to further secure the graft and minimize flow by.

Title: Translatable carriage fixation system
Inventor: KOCH DAVID
IPC: A61B17/00
Filed: 2005-09-01
Abstract: Translational bone fixation assemblies, kits containing such assemblies, and methods of use are described herein. The described assemblies may be used in spinal fusion procedures in which a damaged or diseased disc (or part of a disc) is removed from between a pair of vertebrae and a spinal fusion spacer is placed between the vertebrae. The assemblies may be applied to an anterior portion of the affected vertebrae to span the affected disc space, and may be fixed to the vertebrae using bone screws. The assemblies may function to maintain the vertebrae aligned during the initial period following fixation in which fusion of the spacer to the adjacent vertebrae occurs. The assemblies may also function to share some of the axial spinal load applied to the fusion spacer to prevent extreme subsidence of the spacer into the vertebral body, such as where the patient has poor bone quality.

Patent CA-2589685-A1 (CA)
Inventor: YMKER LEO
IPC: F16H57/00
Filed: 2005-11-29
Abstract: The invention relates to an electrically driven linear actuator for linearly moving a mass, in which at least one elongated actuator element, which, on the output side, acts upon the mass, is mounted inside a main pipe in a manner that enables it to slide in an axial direction, and which, on the input side, is coupled to a spindle nut.  The spindle nut rests upon the spindle in such a manner that it, during its axial motion caused by a rotation of the spindle, displaces each actuator element in a telescopic manner with regard to the main pipe. In order to prevent oscillations of the drive from leading to vibrations on the mass that is to be moved, the invention provides that each actuator element is formed from two pipes that are arranged concentrically while forming a tubular gap.

Patent CA-2593238-A1 (CA)
Inventor: ALLEN EDWARDS
IPC: C12N5/04
Filed: 2006-01-06
Abstract: A method to generate siRNAs in vivo is described, as are constructs and compositions useful in the method. The method does not depend on the use of DNA or synthetic constructs that contain inverted duplications or dual promoters so as to form perfect or largely double-stranded RNA. Rather, the method depends on constructs that yield single-stranded RNA transcripts, and exploits endogenous or in vivo-produced miRNAs or siRNAs to initiate production of siRNAs. The miRNAs or siRNAs guide cleavage of the transcript and set the register for production of siRNAs (usually 21 nucleotides in length) encoded adjacent to the initiation cleavage site within the construct.  The method results in specific formation of siRNAs of predictable size and register (phase) relative to the initiation cleavage site. The method can be used to produce specific siRNAs in vivo for inactivation or suppression of one or more target genes or other entities, such as pathogens.
Patent CA-2593611-A1 (CA)
Title: Soft close ring binder mechanism
Inventor: CHENG HUNG YU
IPC: B42F3/04
Filed: 2005-01-24
Abstract: A ring binder mechanism that retains loose-leaf pages and has ring members that do not snap together when they close and that easily open and close as pages accumulate. The mechanism includes a housing that supports two hinge plates for loose pivoting motion, moving the ring members apart or together. The mechanism further includes an actuating lever pivotally mounted on the housing. The lever moves a travel bar and locking elements for controllably pivoting the hinge plates, and therefore controllably moving the ring members apart and together. In particular, the locking elements cam the hinge plates to softly close the ring members. When the ring members are apart, the locking elements register with openings in at least one of the hinge plates. When the ring members are together, the locking elements are out of registration with the openings, blocking the hinge plates from pivoting to separate the ring members.
