摘要:
A surgical fastening device for pinning a surgical filament to a body tissue. The device includes a grasping handle and a slender shaft extending from the grasping handle. A compartment contains one or more surgical fasteners. An ejecting mechanism is used to eject a surgical fastener from a compartment containing one or more surgical fasteners. The device also includes a filament dispensing system that dispenses surgical filament along the shaft so that a fastener grasps the filament when being ejected from the shaft. The invention also provides surgical fasteners and surgical filaments for use in the device.
摘要:
A surgical instrument suitable for endoscopic operations having a gripping handle, tubular body and an operational tip. Jetting outlets laterally disposed at the operational tip provides for jetting pressurized liquid delivered by the tubular body. The jetting outlets are configured as to emit converging jets. Two or more jets converge at a convergence point laterally displaced at a predefined distance from the surface of the operational tip. The operational tip includes a heating member having an active face for contact heating a bleeding tissue. A rotating mechanism provides for independently rotating the jetting outlets and the active surface of the heating member relative to the gripping handle. A method for regulating the operating temperature of the heating member is provided.

A system and method are provided for thermally treating tissues in percutaneous surgery or endoluminal treatments. The system consists of at least one catheter for thermally treating a tissue, hydraulic unit for circulating fluids through the catheters and a control station by which an operator is displayed with, and inputs and/or modifies, working parameters of the system. The catheters have an operational face, which is optionally expandable and encloses a lumen through which the fluids are circulated. The method disclosed implements cooling of the targeted tissue prior to its heating. For heating and or cooling the tissues, the operational face of a catheter is pressed against a surface of the targeted tissue while heat emitted from or conducted to the tissue is respectively transferred into or from the circulated fluids.
摘要:
The application provides a device (2) for extracting from a body tissue surgical fasteners (20) having a crown, a baseplate and prongs extending from the crown to the baseplate. The device includes a shaft having a lumen with a cross-sectional shape and dimensions to allow the crown to enter the lumen while preventing the baseplate from entering the lumen.

The invention provides fasteners for surgical fastening. The surgical fastener of the invention has a crown from which extend two or more prongs. The prongs are parallel to the axis of the crown and each prong is provided with one or more barbs. The invention also provides a system for surgical fastening device configured to deploy one or more surgical fasteners of the invention and one or more surgical fasteners of the invention.
摘要:
An anastomosis device for forming two lumen-comprising body structures having an un-deployed and a deployed state and switchable from the former to the latter, comprising: a body with an overall cylindrical shape defining a proximal-distal extending axis of and comprising an external essentially cylindrical body part with a lumen and an internal body part at least a portion thereof being deployed within the lumen of the external body part and axially displacable with respect thereto in the switch between the un-deployed and the deployed states; said internal body part having an internal duct extending axially therethrough whereby in the deployed state there is a fluid communication between the distal and the proximal ends of the body; and two tissue-engaging units axially displaced from one another along said axis; at least one of the two units can change its state from a closed state in the un-deployed state of the device to an opened, tissue-engaging state in the deployed state of the device in which said first unit extends in an overall radial direction and is adapted in this state for tight association with internal walls of one of the body structures, such that the combined tissue-engaging action of the two unit holds the two structures together.

摘要:
The present invention relates to tumor associated antigen (TAA) peptides and to use of same, of polynucleotides encoding same and of cells presenting same as anti-tumor vaccines. More particularly, the present invention relates to tumor associated antigen peptides derived from Uroplakin Ia, Ib, II and III, Prostate specific antigen (PSA), Prostate acid phosphatase (PAP) and Prostate specific membrane antigen (PSMA), BA-46 (Lactadherin), Mucin (MUC-1), and Teratocarcinoma-derived growth factor (CRIPTO-1) and the use of same as anti-tumor vaccines to prevent or cure bladder, prostate, breast or other cancers, carcinomas in particular. Most particularly, the present invention relates to tumor associated antigen peptides which are presentable to the immune system by HLA-A2 molecules.
摘要:
A device for controlling the expansion of a hollow internal organ, comprising an inflatable balloon, which is inserted in an uninflated state into the desired position close to the organ using minimally invasive procedures. After insertion, the balloon is inflated to its required size and shape. The invention is useful for restricting the expansion of the stomach during meals, thus inducing a feeling of satiety and preventing over-eating. Inflation may be performed through a catheter connected to a readily accessible inflation port. In the case of the gastric embodiment, the balloon may be positioned pro-peritoneally, such that the procedure is surgically simple. One or more sensors located close to the organ to be controlled, may monitor a physiological effect relating to the organ, and the output of the sensor used to control the level of inflation of the balloon in order to correct the condition being monitored.
摘要:
A tissue displacement/separation device is provided. The device includes a bladder which is expandable between a first tissue and a second tissue of a body. The bladder has an expanded shape which is selected capable of displacing or separating the first tissue from the second tissue in a manner suitable for protecting the first tissue from an effect of a treatment applied to the second tissue.
