摘要： A small gauge pulsed electric field/aspirator probe. The probe has a generally cylindrical cannula with a generally smooth distal end. A port is located near a distal end of the cannula on a side of the cannula. A pair of electrodes is located at the port. An electric pulse generator is coupled to the pair of electrodes. A distance between the distal end of the cannula and the port is approximately equal to the distance between a back wall of Schlemm's canal and a trabecular meshwork in a human eye. The electric pulse generator applies a pulsed electric field to the pair of electrodes sufficient to dissociate protein bonds that hold the trabecular meshwork together.

摘要： A catheter usable for cryogenic ablation of tissues is described. The catheter has a deflectable segment with a reduced diameter and a tip portion with a diameter greater than the reduced diameter. A resilient element allows for bending of the deflectable segment preferentially in one plane, and an actuator is used to control the bending of the deflectable segment.

摘要： A sheath for use on a closed loop Joule-Thomson cryosurgical probe, and the combination of the sheath and the closed loop probe. The sheath is slipped over the probe, thereby separating the probe from the environment. The sheath has a grip which fits over the handle of the cryosurgical probe, and an extendible shroud which can be longitudinally extended to cover tubing and which are attached to the handle. The sheath has a hollow multi-lumen catheter shaped and sized to fit snugly over the cannula of the cryosurgical probe. The catheter is not thermally conductive, preventing transfer of heat from the ambient to the gas mixture, and preventing the freezing of tissues at undesired locations along the catheter. A thermally conductive cap or tip is attached to the distal end of the hollow catheter. The thermally conductive cap or tip is biased against the cold tip on the probe by a biasing element in the sheath assembly, to promote heat transfer.
摘要翻译：用于闭环焦耳汤姆逊冷冻手术探针的鞘，以及鞘和闭环探针的组合。护套滑过探头，从而将探头与环境分开。护套具有装配在冷冻手术探针的手柄上的把手，以及可延伸的护罩，其可以纵向延伸以覆盖管道并且附接到手柄。护套具有中空的多腔导管，其形状和尺寸适于紧贴在冷冻手术探针的套管上方。导管不是导热的，防止热量从环境转移到气体混合物，并且防止沿着导管在不期望的位置处冷冻组织。导热帽或尖端连接到中空导管的远端。导热帽或尖端通过护套组件中的偏置元件偏压在探针上的冷尖端上，以促进热传递。
