MEDICAL APPARATUS WITH TRANSLATABLE IMAGING DEVICE FOR REAL-TIME CONFIRMATION OF INTERCEPTION OF TARGET TISSUE

摘要

A medical apparatus includes a catheter, a medical instrument assembly, and an imaging assembly. The catheter having a first working channel terminating with a first distal exit, and a second working channel extending terminating with a second distal exit. The medical instrument assembly having a medical instrument adapted to be housed within the first working channel and adapted to be extendable through the first distal exit to an extended position beyond the first distal exit to intercept a target tissue. The imaging assembly includes an imaging device adapted to be housed within the second working channel and is extendable through the second distal exit to an extended position beyond the second distal exit. The imaging device is adapted to generate an image in an image plane of the distal end of the medical instrument when the distal end of the medical instrument is extended out the first distal exit.

1. A medical apparatus, comprising:
a catheter comprising a first elongate flexible shaft having a proximal end portion, a distal end portion, the proximal end portion comprising a first port and a second port, the distal end portion comprising a first distal exit and a second distal exit, wherein a first working channel extends between the first port and the first distal exit, and a second working channel extends between the second port and the second distal exit; a medical instrument assembly comprising a medical instrument, wherein the medical instrument has a proximal end and a distal end and is adapted to be housed within the first working channel, and wherein the distal end of the medical instrument is extendable through the first distal exit to an extended position beyond the first distal exit; and an imaging assembly comprising a second elongate flexible shaft having a proximal end portion and a distal end portion, and an imaging device affixed the distal end portion of the second elongate flexible shaft, the imaging device adapted to be housed within the second working channel and wherein the imaging device is extendable through the second distal exit to an extended position beyond the second distal exit, wherein the imaging device is adapted to generate an image in an image plane of the distal end of the medical instrument when the distal end of the medical instrument is extended out the first distal exit.
