Abstract: A mammary tissue expander device including an inflatable shell having an anterior side and a posterior side, the anterior side having an upper pole portion and a lower pole portion meeting at an apex, and an injection port for receiving fluid therethrough to inflate the expander, and a substantially flat attachment flap coupled to the posterior side of the shell, and extending in an inferior direction beyond an inferior edge of the shell by a distance D such that the attachment flap may be extended around the inferior edge and upwards to overlay at least a portion of the anterior side of the shell.

Abstract: An expandable mammary implant including a shell having an anterior face and a posterior face. The anterior has an upper pole portion and a lower pole portion meeting at an apex, and an injection zone for receiving fluid therethrough to inflate the implant. A reinforcement material is coupled to the shell in a reinforcement zone. The reinforcement material is coupled to the shell so as to at least coincide with the upper pole portion and a peripheral rim portion that extends from the posterior face upwardly into said anterior face by a predetermined distance.

Abstract: Surgical cooling may be implemented by various systems, processes, and techniques. In certain implementations, a surgical cooling device includes a shaft, a cooling assembly, and a mechanical control system. The shaft includes a pair of axial cooling channels extending through its interior. The cooling assembly includes a pair of arms pivotally attached to the shaft and a foldable thermal exchanger coupled to the pair of arms and fluidly coupled to the pair of axial cooling channels. The mechanical control system is adapted to unfold the cooling assembly from a closed position to an open position to allow a coolant to flow through a first of the pair of axial cooling channels, through one or more thermal exchange channels, and out a second of the pair of cooling channels.

Abstract: An expandable mammary tissue implant including a shell having an anterior face and a posterior face, the anterior face having an upper pole portion and a lower pole portion meeting at an apex, and an injection zone for receiving fluid therethrough to inflate the implant. The implant further includes a vertical tether member having first and second ends and a central region therebetween having an aperture therethrough. The central region is coupled to the anterior face of the implant at a location such that the injection zone is positioned within the aperture in the central region. The first and second ends of the vertical tether member are coupled to the posterior face of the implant.

Abstract: During root canal procedures, pulp may be removed from a tooth without disturbing the dentin by directing pulses of a heated liquid onto the pulp at particular temperatures and pressures to liquefy or gellify the pulp. The liquefied or gellified material is then aspirated away using the methods and apparatuses described herein. In some embodiments the heated liquid also functions to kill bacteria that may be present within the tooth.

Abstract: A balloon dilatation catheter is provided which has a stiff proximal cannula made of a material such as metal hypotubing. The distal end of the catheter includes an inflatable medical device balloon, an inflation lumen and a guidewire lumen. A coiled transition assembly is positioned between the proximal cannula and the distal end section. This coiled transition assembly has a tightly wound coil within a tube and provides for a flexible transition between the two components of diverse stiffness, namely the proximal cannula and the flexible distal end portion. The dilatation catheter typically has an easily or rapidly exchangeable feature and is used in conjunction with a guiding catheter. During a procedure when the catheters are within the vascular system, the coiled transition section of the dilatation catheter readily follows tightly curved portions of the inserted guiding catheterby.
