Abstract

An instrument catch for an instrument guide configured to attach to an ultrasound imaging probe to guide an instrument for a procedure. The instrument catch comprising a first inner wall, a second inner wall, a first end along a length, a second end along the length, a valley that extends along the length, and a port at an end of the valley. The first ends of the first and second inner walls along a height meet at the valley, protrude up from the valley, and extend in opposing directions forming a channel that tapers from opposing second ends of the first and second inner walls along the height to the first ends of the first and second inner walls.

First claim

The invention claimed is:

1 . An instrument catch for an instrument guide configured to attach to an ultrasound imaging probe to guide an instrument for a procedure, the instrument catch, comprising:
a first inner wall; a second inner wall; a distal end along a length; a proximal end along the length; a valley that extends along the length; a port at an end of the valley; and a cone disposed at the distal end of the instrument catch, wherein the valley extends through an interior of the cone to the port at the distal end; wherein lower ends of the first and second inner walls along a height meet at the valley, protrude up from the valley, and extend in opposing directions forming a channel that tapers outwards from the lower ends to upper ends of the inner walls, wherein the upper end of the first wall defines a first edge extending along the length and the upper end of the second wall defines a second edge extending along the length, the first and second edges being parallel, wherein the first and second edges terminate into a proximal side of the cone.

2 . The instrument catch of claim 1 , wherein the channel is “V” shaped.

3 . The instrument catch of claim 1 , wherein the first and second inner walls are one of planar, concave, or convex.

4 . The instrument catch of claim 1 , further comprising:
a magnet disposed under the valley.

5 . The instrument catch of claim 1 , wherein the catch is translucent.

6 . An instrument catch for an instrument guide configured to attach to an ultrasound imaging probe to guide an instrument for a procedure, the instrument catch, comprising:
a first inner wall; a second inner wall; a valley that extends along a length; a cone disposed at a distal end of the valley; and a magnet, wherein lower ends of the first and second inner walls along a height meet at the valley, and the magnet is disposed at least under the valley, wherein an upper end of the first wall defines a first edge extending along the length of the catch and an upper end of the second wall defines a second edge extending along the length, the first and second edges being parallel, wherein the first and second edges terminate into a proximal side of the cone.

7 . The instrument catch of claim 6 , wherein the magnet is encapsulated in the catch.

8 . The instrument catch of claim 6 , wherein the catch includes a magnet carrier below the valley and the magnet is removably installed in the magnet carrier.

9 . The instrument catch of claim 6 , wherein the magnet is affixed in a recess in the catch below the valley.

10 . The instrument catch of claim 6 , wherein the catch includes a translucent material.

11 . The instrument catch of claim 6 , wherein the catch is cone shaped and the magnet is one of cone or ring shaped.

12 . The instrument catch of claim 7 , further comprising:
a distal end along the length; a proximal end along the length; and a port at a distal end of the valley; wherein the lower ends of the first and second inner walls along the height meet at the valley, protrude up from the valley, and extend in opposing directions forming a channel that tapers inwards from opposing upper ends of the first and second inner walls along the height to the lower ends of the first and second inner walls.

13 . An instrument catch for an instrument guide configured to attach to an ultrasound imaging probe to guide an instrument for a procedure, the instrument catch, comprising:
a first inner wall; a second inner wall; a valley that extends along a length; and a cone disposed at a distal end of the valley, wherein lower ends of the first and second inner walls along a height meet at the valley, and the catch includes a translucent material wherein an upper end of the first wall defines a first edge extending along the length of the catch and an upper end of the second wall defines a second edge extending along the length, the first and second edges being parallel, wherein the first and second edges terminate into a proximal side of the cone.

14 . The instrument catch of claim 13 , further comprising:
a distal end along the length; a proximal end along the length; and a port at a distal end of the valley, wherein, the first and second inner walls protrude up from the valley and extend in opposing directions forming a channel that tapers inwards from opposing upper ends of the first and second inner walls along the height to the lower ends of the first and second inner walls.

15 . The instrument catch of claim 14 , further comprising:
a light source.

16 . The instrument catch of any of claim 14 , further comprising:
a magnet disposed under the valley.

17 . The instrument catch of claim 16 , wherein the magnet is removably installed under the valley.

18 . The instrument catch of claim 16 , wherein the magnet is a component of the catch.
