    摘要: An apparatus for treating tissue in a tissue treatment region. The apparatus can comprise an electrode ring having an interior perimeter and an electrode probe having a proximal end and a distal end. The distal end of the electrode probe can be structured to axially translate relative to the interior perimeter of the electrode ring. The electrode ring and the electrode probe can be operably structured to conduct current therebetween when at least one of the electrode ring and the electrode probe is energized by an energy source. Further, the energy source can be a Radio Frequency (RF) energy source, a pulsed energy source, an irreversible electroporation energy source, or a pulsed irreversible electroporation energy source. A current from the energy source can be selected to non-thermally ablate tissue in the tissue treatment region.

    摘要: A first medical instrument includes a flexible catheter and a medical guidewire extendable beyond a distal end of the catheter. The catheter has an articulated section. The medical guidewire has first and second segments, wherein the bending moment of inertia of the first segment is less than the bending moment of inertia of the second segment. A second medical instrument includes a flexible catheter, a mechanized guidewire assembly, and a medical guidewire extendable beyond a distal end of the catheter. The catheter has an articulated section. The medical guidewire has an exterior surface including a repetitive series of spaced-apart surface elevation features. One example of surface elevation features is external threads. The spaced-apart surface elevation features are adapted for operable engagement with the mechanized guidewire drive assembly.

    摘要: Methods and devices are provided for controlling movement of a working end of a surgical device configured to be introduced into a body. In one embodiment, a surgical device is provided including a cannulated elongate shaft having a distal working end with a flexible steering platform. The flexible steering platform can includes a plurality of axially aligned links and a plurality of flexible connector elements. Adjacent links can be connected using at least two of the connector elements such that flexing one or more connector elements can bend the steering platform in one or more directions. The surgical device's shaft can be configured to receive a flexible surgical instrument therein such that a working end of the surgical instrument can be received within the steering platform, thereby allowing movement of the surgical instrument's working end to be controlled through movement of the steering platform.

    摘要: Methods and devices are provided for deploying and applying a suture anchor. In one embodiment, a surgical device is provided having a shaft configured to be introduced into a body and to deliver a suture anchor with a coil of suture attached thereto to tissue. The shaft can be configured to deploy the suture anchor through tissue and to deliver the coil of suture into a body cavity such that the suture extending from the coil extends through the tissue to allow the anchor to engage the tissue. The coil can remain in the body cavity for subsequent use.

    摘要: A surgical instrument, such as an electrical ablation device, includes an elongate member having therealong disposed a first electrode extending along an axis. A first expandable portion extends along the axis and defines a first perimeter of the first electrode and has an associated first diameter with respect to the axis. The first expandable portion includes a first framework selectively expandable to transition the first expandable portion from a contracted state to an expanded state. The first framework is selectively contractible to transition the first expandable portion from the expanded state to the contracted state. When the first framework is expanded, the first diameter is expanded and the first expandable portion is transitioned from the contracted state to the expanded state. When the first framework is contracted, the first diameter is contracted and the first expandable portion is transitioned from the expanded state to the contracted state.
