Medical device with deflecting shaft and related methods of manufacture and use
First Claim
1. A medical device for use with an endoscope, comprising:
- a proximal handle;
a distal assembly for performing a medical procedure; and
an elongated member connecting the proximal handle to the distal assembly, the elongated member having a proximal portion and a distal portion, the distal portion having a flexibility greater than a flexibility of the proximal portion so as to selectively deflect the distal portion relative to the proximal portion,wherein actuation of a single moving part of the proximal handle causes both deflection of the distal portion and actuation of the distal assembly to perform the medical procedure.

Abstract
Various embodiments of a medical device having a deflecting shaft and related methods of manufacture and use are disclosed. For example, the device may include a proximal handle, a distal assembly for performing a medical procedure, and a wire coil connecting the proximal handle to the distal assembly, wherein actuation of the proximal handle may cause the distal assembly to perform the medical procedure. The wire coil may have a proximal portion comprised of a first wire and a distal portion comprised of a second wire. The second wire may have a diameter less than a diameter of the first wire so that the distal portion of the wire coil may have a flexibility greater than a flexibility of the proximal portion.
