Abstract

A medical system is provided comprising a medical device including a handle and a mechanism for moving a distal end of the medical device; an auxiliary medical device comprising a basket retrieval device including a basket sheath disposed over a basket wire and received into a working channel of the medical device; a knob assembly in communication with the basket retrieval device, the knob assembly rotatable so that the basket sheath, wire, or both move within the working channel; and a base removably connecting the auxiliary medical device to the handle wherein the handle and the base are configured to be simultaneously gripped with a hand, and wherein the mechanism is configured to be moved with a first finger to move the distal end of the medical device and the knob assembly is configured to be rotated with a second finger to move the basket sheath wire, or both.

First claim

1 . (canceled)

2 . (canceled)

3 . The medical system of claim 6 , wherein the base includes at least one resiliently deflectable finger removably connecting the auxiliary medical device to the handle.

4 . The medical system of claim 6 , wherein the knob assembly includes an inner knob in communication with the basket retrieval device and an outer knob engaging the inner knob, the outer knob includes a gripping ridge, a lever, or both,
wherein the outer knob is rotatable in the first direction, the second direction, or both by engaging the gripping ridge, the lever, or both with the second finger.

5 . The medical system of claim 6 , wherein the knob assembly includes an auxiliary lever,
wherein the auxiliary lever is moveable with the first finger or the second finger so that one or both of the inner knob and the outer knob rotate, and wherein movement of the auxiliary lever causes:
i. the basket wire and the basket to collapse, retract, or both into the basket sheath, the distal end of the medical device, or both, and/or
ii. the distal end of the medical device to move.

6 . A medical system comprising:
I. a medical device, the medical device including a handle and a mechanism for moving a distal end of the medical device; and II. an auxiliary medical device, the auxiliary medical device comprising:
i. a basket retrieval device including a basket sheath disposed over a basket wire, the basket sheath, the basket wire, or both are received into a working channel of the medical device;
ii. a knob assembly in communication with the basket retrieval device, the knob assembly is rotatable so that the basket sheath, the basket wire, or both move within the working channel of the medical device; and
iii. a base connected to the knob assembly, the base removably connecting the auxiliary medical device to the handle of the medical device,
wherein the medical device is an endoscope, a ureteroscope, or both, and the basket retrieval device includes a basket connected to a distal end of the basket wire, wherein the handle and the base are configured to be simultaneously gripped with a hand of a user, wherein the mechanism is configured to be moved with a first finger of the hand to move the distal end of the medical device and the knob assembly is configured to be rotated with a second finger of the hand to move the basket sheath, the basket wire, or both relative to the distal end of the medical device, wherein moving the mechanism with the first finger causes the distal end of the medical device to deflect, bend, or both, wherein rotating the knob assembly with the second finger in a first direction cases the basket wire and the basket to deploy from the basket sheath, the distal end of the medical device or both so that an object can be captured, wherein rotating the knob assembly with the second finger in a second direction causes the basket wire and the basket to collapse, retract, or both into the basket sheath, the distal end of the medical device, or both, and wherein a biasing member that is in communication with the knob assembly helps rotate the knob assembly from the second direction to the first direction.

7 . The medical system of claim 6 , wherein the knob assembly includes an opening configured to engage a connector port on the medical device so that the basket retrieval device is generally aligned with and can be inserted into a working channel port on the medical device.

8 . The medical system of claim 4 , wherein the first direction is generally perpendicular to a direction that the basket wire and the basket deploy from the basket sheath, the distal end of the medical device, or both.

9 . The medical system of claim 4 , wherein first direction is generally the same as a direction that the basket wire and the basket deploy from the basket sheath, the distal end of the medical device, or both.
