Abstract
An endoscopic biopsy device having an outer sheath that is transparent, at least along a portion thereof, to allow visualization of at least a portion of the inside of the device. A distal portion of the outer sheath may be relatively more opaque or relatively less reflective to avoid glare that may otherwise result due to the sheath reflecting light from the endoscopic light source.
Claims46
A biopsy forceps device, comprising:
- an elongate shaft having a proximal end and a distal end;
- an effector assembly connected to the distal end of the elongate shaft;
- a handle connected to the proximal end of the elongate shaft and operably connected to the effector assembly for actuation thereof;
- and
- a polymer sheath disposed about the elongate shaft, the polymer sheath having a transparent portion to permit visualization of the shaft therethrough.
A biopsy forceps device, comprising:
- an elongate shaft having a proximal end and a distal end;
- an effector assembly connected to the distal end of the elongate shaft;
- a handle connected to the proximal end of the elongate shaft and operably connected to the effector assembly for actuation thereof;
- and
- a polymer sheath disposed about the elongate shaft, the polymer sheath having a proximal portion and a distal portion, wherein at least the proximal portion includes a transparent section to permit visualization of the elongate shaft therein.

- an elongate shaft having a proximal end and a distal end;
- an effector assembly connected to the distal end of the elongate shaft;
- a handle connected to the proximal end of the elongate shaft and operably connected to the effector assembly for actuation thereof;
- and
- a polymer sheath disposed about the elongate shaft, wherein at least a portion of the polymer sheath is transparent.
An biopsy forceps device, comprising:
- an elongate shaft including a proximal end and a distal end;
- wherein a flexible coil is disposed about at least a portion of the shaft;
- an effector assembly connected to the distal end of the elongate shaft;
- a handle connected to the proximal end of the elongate shaft and operably connected to the effector assembly for actuation thereof;

- a polymer sheath disposed about the coil, wherein at least a portion of the polymer sheath is transparent.
A method of manufacturing an elongate shaft for use with a biopsy device, comprising the steps of:
- providing an elongate member having a proximal end and a distal end;
- coupling a transparent first outer portion to the elongate member;
- coupling a second outer portion to the elongate member;
- attaching a handle to the proximal end of the elongate member;
- and
- attaching an effector assembly to the distal end of the elongate member.
A biopsy forceps device, comprising:
- an elongate shaft having a proximal end and a distal end;
- an effector assembly connected to the distal end of the elongate shaft;
- a handle connected to the proximal end of the elongate shaft and operably connected to the effector assembly for actuation thereof;
- a first control wire having a proximal end coupled to the handle and a distal end coupled to the effector;
- a second control wire having a proximal end coupled to the handle and a distal end coupled to the effector;
- and
- a polymer sheath disposed about the elongate shaft, wherein at least a portion of the polymer sheath is transparent.
