CATHETER AND HANDLE ASSEMBLY, SYSTEMS, AND METHODS

摘要

A catheter and handle assembly for use in treating tissue. More specifically, the invention relates to a catheter assembly having an elongate shaft, ablation assembly coupled to one end of the shaft, and a handle coupled to the other end of the shaft. The handle facilitates both axial and circumferential positioning of the ablation assembly via the shaft in an airway, conduit, or vessel for treatment of the tissue. Embodiments include the use of a handle to facilitate the axial and circumferential positioning of the shaft and ablation assembly through and independent of a working channel of a bronchoscope during treatment for pulmonary disease like COPD and asthma.

主权项

1. A catheter and handle assembly for coupling to a delivery device, the delivery device having a proximal working port, a distal working end, and a working channel extending between the working port and the working end defining a working length, the assembly comprising:
a catheter assembly including
an elongate shaft,an ablation assembly coupled to a first end of the elongate shaft, the ablation assembly having an energy emitter thereon; a handle assembly coupled to a second end of the elongate shaft, the handle assembly including
a handle frame and a control, the control being movable relative to the handle frame and coupled to the elongate shaft such that moving the control moves the ablation assembly in at least one or an axial and a circumferential direction relative to the handle frame; and a coupling assembly configured to couple to the handle assembly and the working port of the delivery device, the coupling assembly configured to remain fixed relative to the delivery device and the handle frame while the control is moved to move the ablation assembly, wherein a first portion of the elongate shall extends within and through the working channel of the delivery device when the handle assembly is operably coupled to the delivery device via the coupling assembly.
