Inventor: HETE BERNIE F
IPC: A61M16/00
Filed: 1999-12-20
Abstract: This invention is an insufflation system (56) that includes a first tube (62) that inserts into a patient's airway for providing a primary flow of breathing gas to such a patient. At least one insufflation catheter (66) is provided in or within the first tube for delivering a flow of insufflation gas to the patient.      In one embodiment, the flow of insufflation gas is delivered in a first direction generally toward the patient's lungs and in a second direction generally opposite the first direction so that the flow in the second direction creates a negative stagnation pressure that substantially cancels out the positive stagnation pressure generated by flow in the first direction. In a second embodiment, an exhaust vent (70) is provided in the first tube for exhausting a flow of gas from the first tube at a rate that is equivalent to the rate at which the flow of insufflation gas is being delivered to the patient's airway, thereby preventing over-inflation of the patient's respiratory system. A third embodiment of the present invention involves a combination of the two embodiments discussed above.

Title: Low profile radio-opaque stent with increased longitudinal flexibility and radial rigidity
Inventor: MAJERCAK DAVID
IPC: A61F2/915
Filed: 2001-08-10
Abstract: The current invention is a comparatively thick-walled vascular stent comprising sets of strut members connected by flexible links. This design uses a script "N" shaped flexible link. The "N" links are designed to nest one into the other, allowing the stent to be both thick-walled and to crimp down without overlap onto a low profile balloon. The "N" links are attached to the strut members off center near the end of the curved end strut portion of each strut member. This off center attachment point allows for a more flexible link without increasing the cell size of the expanded stent. The "N' links maintain a width to thickness ratio of at least 1.5 to one.

Filed: 2000-12-12
Abstract: L'invention concerne un matériel cathodique contenant un PVM qui s'utilise dans des cellules électrochimiques rechargeables. Selon l'invention, le squelette polymère du PVM, uniquement constitué d'atomes de carbone, ne subit pas de rupture pendant les cycles répétés de charge-décharge, si bien que le matériel cathodique demeure sensiblement insoluble dans des électrolytes liquides normaux. Il en résulte que les cellules contenant le PVM (en tant que matériel cathodique) et l'électrolyte liquide sont véritablement réversibles par procédé électrochimique. L'emploi du PVM élimine les problèmes liés à l'usage d'organosulfures dans la technique antérieure, lequel usage entraîne la dissolution d'anions dans l'électrolyte liquide pendant la décharge, ce qui provoque une migration de la cathode et la contamination de la surface anode-électrolyte aboutissant à la dégradation de l'électrolyte et/ou à la détérioration de l'interface anode-electrolyte.
