Abstract

Adjacent tissue layers can be accessed using a catheter device with a distal tip having a conductive portion including a first cutting feature and one or more projections extending from the first cutting feature towards an outer diameter of the distal tip. Electrical energy can be supplied to the conductive portion of the device to cut tissue. A stent can be delivered to form a fluid communication between the adjacent tissue layers.

Claims (5)

1 . A distal tip for a catheter, comprising:

a tapered tip having a proximal end having a first diameter, a distal end having a second diameter, and a lumen extending therethrough, wherein the first diameter is greater than the second diameter;

a distal tip base disposed on the proximal end of the tapered tip, the lumen extending through the distal tip base; and

a conductive cutting member coupled to the distal end of the tapered tip, the conductive cutting member comprises a forward facing cutting feature and at least one outward projecting cutting feature,

wherein the forward facing cutting feature is disposed on the distal end of the tapered tip and has a diameter smaller than the second diameter and larger than a diameter of the lumen.
