Tissue and stone removal device and related methods of use
Embodiments of a medical device and related methods of use are provided for extracting tissue. The device may include an elongate member having a proximal end and a distal end. Two or more channels may extend through the elongate member from the proximal end to the distal end, and a morcellating device may be included in one of the channels. In addition, one of the channels may be configured as a return channel for extracting the morcellated tissue.
1. A medical device for extracting tissue, the device comprising:
an elongate member having a proximal end and a distal end;
two or more channels extending through the elongate member from the proximal end to the distal end, wherein one of the two or more channels is a return channel configured for extracting resected tissue; and
a resection device configured to resect tissue wherein the resection device is a laser fiber directly secured to an inner surface of the return channel and remains in a rotationally and axially fixed location relative to the elongate member.
2. The device of claim 1 , wherein the elongate member is flexible.
3. The device of claim 1 , wherein the elongate member is rigid.
4. The device of claim 1 , further including a metallic tip secured to a distal end of the return channel.
5. The device of claim 4 , wherein the metallic tip includes a lumen configured to pass resected tissue therethrough and having an inner diameter smaller than that of an inner diameter of the return channel.
6. The device of claim 4 , wherein the laser fiber is secured to an inner surface of the metallic tip with a resin that occupies a portion of an inner diameter of the metallic tip.
7. The device of claim 1 , wherein the distal end of the elongate member includes a metallic tip.
8. The device of claim 1 , wherein the return channel is operably coupled to a suction device.
9. The device of claim 1 , wherein the return channel is tapered at the distal end.
10. The device of claim 1 , further including a visualization device in one of the two or more channels.
11. The device of claim 1 , further including a light source carried in one of the two or more channels.
12. An apparatus for extracting tissue, the apparatus comprising:
an elongate member having a proximal end and a distal end;
a plurality of channels extending through the elongate member from the proximal end to the distal end, wherein one of the plurality of channels is a return channel configured for extracting resected tissue and wherein a laser fiber configured to resect tissue is directly secured to an inner surface of the return channel and remains in a rotationally and axially fixed location relative to the elongate member, and wherein the plurality of channels include differing configurations;
a visualization device configured to observe the tissue in one of the plurality of channels other than the return channel; and
a light source configured to illuminate tissue, carried in one of the plurality of channels other than the return channel.
13. The apparatus of claim 12 , wherein the return channel is operably coupled to a suction device for extracting resected tissue.
14. The apparatus of claim 12 , wherein the distal end of the elongate member includes a rigid tip.
15. The apparatus of claim 14 , wherein the laser fiber is secured to an inner surface of the rigid tip with a resin that occupies a portion of an inner diameter of the rigid tip.
16. The apparatus of claim 14 , wherein the rigid tip includes a lumen configured to pass resected tissue therethrough and having an inner diameter smaller than that of an inner diameter of the return channel.
17. The apparatus of claim 12 , further comprising an irrigation system carried in one of the plurality of channels.
