Particles

An RF ablation device comprises an electrode including a DLC coating deposited on at least a portion thereof. A method of forming an RF ablation device, comprises forming a DLC coating on a portion of a metallic electrode.

Diamond-like carbon electrode coating

Medical probe kits and methods for treating tissue regions (e.g. tumors) are provided. The kit comprises a delivery cannula and an ablation probe. The delivery cannula comprises a shaft, a lumen extending through the shaft, and a plurality of windows formed through a wall of the shaft in communication with the cannula lumen. The ablation probe is configured to be removably disposed within the cannula lumen. The ablation probe has a shaft and proximal and distal arrays of electrodes that are deployable from the probe shaft. The electrodes of the proximal array are configured to be deployed out from the respective windows when the ablation probe is disposed within the cannula lumen. The electrodes of the distal array may be configured to be deployed out from an axial opening at the distal end of the cannula shaft when the ablation probe is disposed within the cannula lumen. The method may comprise introducing the cannula within a patient, introducing the ablation probe through the cannula, deploying the electrode arrays into contact with the tissue region, and conveying ablation energy to the ablation probe to ablate the tissue region within the electrode arrays.

Co-access bipolar ablation probe

A stent-graft comprising a stent and a graft having a supported portion lining or covering at least a portion of the stent, and an unsupported portion extending proximally beyond the proximal end of the stent. The stent-graft may have a length corresponding to at least a mean standard length from a standard incision point to a distal-most portion of a standard lumen into which the distal end of the stent is adapted to be deployed, with the unsupported portion of the graft extending beyond the mean standard length by an amount equal to at least two, if not three or more, standard deviations of the mean standard length. A method for deploying the stent-graft comprises making an incision in a wall of the lumen, introducing and deploying the stent-graft in the lumen so that the proximal end extends beyond the incision, and attaching the graft to a lumen by anastamosis.

Stent-graft with adjustable length

A stent comprises a first section and a second section and at least one securement member. The at least one securement member is disposed about at least one region of the first section and at least one region of the second section. The at least one securement member has a crimped diameter that is less than its uncrimped diameter. When the at least one securement member is in the crimped diameter at least a portion of an inner surface of the at least one securement member is fixedly engaged to the at least one region of the first section and the at least one region of the second section. In the crimped diameter the at least one region of the first section and the at least one region of the second section are immediately adjacent one another.

Crimp and weld wire connection

A stent includes regions of differing numbers of braided filaments to provide different dimensions and/or properties in different regions along the stent length. The stent may include a first and second plurality of braided filaments each braided together. The second plurality of braided filaments is braided into the first plurality of braided filaments to form a region of different properties than the first. A method of constructing a braided stent includes the steps of braiding a first plurality of filaments to form the flexible portion, combining a second plurality of filaments to the first plurality of filaments, and then braiding the second plurality of filaments with the first plurality of filaments to form the more rigid region from the combination of the first and second plurality of filaments, where the second plurality of filaments is braided only in the rigid region.

Braided stent and method for its manufacture

A stent and method for making the stent are provided. The stent comprises regions of differing numbers of braided filaments to provide a stent with different dimensions and/or properties in different regions along the stent length. A preferred stent comprises a first and second plurality of braided filaments each braided together. The second plurality of braided filaments is braided into the first plurality of braided filaments to form a region of different properties than the first. A preferred embodiment is a stent having a narrower diameter along a more flexible region and a broader diameter along a more rigid region. Also included is a method of constructing a braided stent in accordance with the above. The method comprises the steps of braiding a first plurality of filaments to form the flexible portion, combining a second plurality of filaments to the first plurality of filaments, and then braiding the second plurality of filaments with the first plurality of filaments to form the more rigid region from the combination of the first and second plurality of filaments, wherein the second plurality of filaments are braided only in the rigid region.
