International Classification:

A61B 17/08

US Classification:

606153, 604544

Abstract:

An anastomosis device providing increased functionality, reliability and safety through the use of designs addressing potential puncture of an inflation balloon being used to hold and approximate tissue. The anastomosis device can include bladder retention structures configured to engage and retain tissue without pointed or sharpened surfaces that can rupture the inflation balloon. The anastomosis device can include a reinforced or otherwise protected inflation balloon to resist puncturing by a bladder retention structure. The anastomosis device can include a catheter wall profile selected to physically prevent bladder retention structures from being forcibly bent back so as to avoid potential contact with and puncture of the inflation balloon. The anastomosis device can include a catheter funnel with an internal spring for preventing kinking of the catheter lumen while providing for flexibility and stretch of the funnel to absorb pulling or shock force which can rupture the inflation balloon.

Abstract:

An anastomosis surgical device comprising an elongate body having a drainage aperture at a distal end for communication with a proximal end of the elongate body, tissue approximating structure extendable from the elongate body and spaced proximally from the drainage aperture along the length of the elongate body. The device further includes an actuating mechanism extending from the proximal end of the elongate body and comprising at least one tissue approximating structure control mechanism, and a protective enclosure surrounding at least a portion of the actuating mechanism.

International Classification:

A61N 5/00

US Classification:

600 3

Abstract:

An apparatus and method for tailoring the radiation intensity about a radiation source, enabling affected zones of a cancerous tissue mass to receive full radiation dosage while limiting the exposure of unaffected regions where radiation exposure is not desired. The assembly includes a radiation attenuator partially covering the outer periphery of a delivery portion of a high dosage radiation catheter, thereby altering the radiation profile that exits the assembly. A method for treating a cancer affected tissue mass includes inserting a plurality of said catheters into a tissue mass about the center of mass and orienting said catheter so that said the maximum radiation intensity is facing substantially toward the center of mass. The radiation source is allowed to dwell in the catheter for a prescribed period of time to deliver the desired dosage of radiation. The radiation source is then removed from the catheter.
