Guide wire loading method and apparatus with towel attachment mechanism
View Patent ↗A device for loading a guide wire into the open end of a tubular instrument, such as a catheter. The device can be a block of material having a groove in its surface. The ends of the guide wire and the tubular instrument are placed into the groove and moved toward each other. When the ends meet, the groove guides the guide wire into the open end of the tubular instrument. The groove, or at least a portion of the groove, can have a cross-sectional contour that closely matches the outside radius of the tubular instrument. The groove can have a substantially vertical wall and a substantially non-vertical wall. A variety of attachment mechanisms may be provided for attaching the device to a towel draping a patient.
1. A medical device for loading a medical guide wire into a selected tubular medical instrument having a selected outside radius, said medical loading device comprising:
a body having a top surface and a bottom surface; and
a plurality of open grooves formed in the top surface of said body for receiving medical guidewires and tubular medical instruments;
wherein each of said plurality of open grooves further comprises:
sides that extend within said body and from said top surface of said body; and
a rounded contour at the bottom of said sides, said rounded contour having a cross section with a radius that matches said outside radius of said selected tubular medical instrument to within plus or minus 10%; and
wherein said sides and said rounded contour of said plurality of open grooves have a combined depth greater than the outside diameter of said selected tubular instrument;
wherein at least one but not all of said plurality of open grooves includes a first portion having a shallower depth than a second portion of said at least one of said plurality, said first portion of said groove having a first rounded contour with a smaller radius than a second rounded contour in said second portion of said groove; and
wherein a different rounded contour is formed in each of at least two of said plurality of grooves, said different contours corresponding to the outside radii of a plurality of different sized selected tubular medical instruments; and
an attachment mechanism coupled to the body, the attachment mechanism for securing the body to a fabric.
2. The medical device recited in claim 1 , wherein the fabric is a towel for draping a patient.
3. The medical device recited in claim 1 , wherein the attachment mechanism is selected from the group consisting of: towel clamps with springs or clips, flexible fork assemblies, flexible tabs, hinged tabs, wire capture systems, gripping rings with flexible fingers, wire-and-plug capture systems, and opposing finger towel capture systems.
4. The medical device recited in claim 3 , wherein the attachment mechanism is an opposing finger towel capture system, and wherein an opposing finger towel capture system is disposed on at least two substantially opposite sides of the body.
5. The medical device recited in claim 1 , further comprising protuberances disposed on the bottom surface of the body.
6. The medical device recited in claim 1 , wherein at least two open grooves are formed in the top surface of said body, wherein each said open groove has a cross section shaped to substantially match said outside radius of said selected tubular medical instrument.
7. A method for loading a medical guide wire into a selected tubular medical instrument, said method comprising:
providing a medical device, the medical device comprising:
a body having a top surface and a bottom surface; and
a plurality of open grooves formed in the top surface of said body for receiving medical guidewires and tubular medical instruments;
wherein each of said plurality of open grooves further comprises:
sides that extend within said body and from said top surface of said body; and
a rounded contour at the bottom of said sides, said rounded contour having a cross section with a radius that matches said outside radius of said selected tubular medical instrument to within plus or minus 10%; and
wherein said sides and said rounded contour of said plurality of open grooves have a combined depth greater than the outside diameter of said selected tubular instrument;
wherein at least one but not all of said plurality of open grooves includes a first portion having a shallower depth than a second portion of said at least one of said plurality of open grooves, said first portion of said groove having a first rounded contour with a smaller radius than a second rounded contour in said second portion of said groove; and
wherein a different rounded contour is formed in each of at least two of said plurality of grooves, said different contours corresponding to the outside radii of a plurality of different sized selected tubular medical instruments; and
an attachment mechanism coupled to the body, the attachment mechanism for securing the body to a fabric;
attaching the medical device to a towel draping a patient using an attachment mechanism;
placing an open end of said tubular medical instrument in said groove at an angle;
placing an end of said medical guide wire in said groove at an angle; and
moving said medical guide wire and said tubular medical instrument toward each other until
said medical guide wire enters said open end of said tubular medical instrument.
8. The method recited in claim 7 , wherein the step of attaching the medical device to a towel includes inserting the towel between two opposing fingers.
9. A medical device for loading a medical guide wire into a selected tubular medical instrument having a selected outside radius, said medical loading device comprising:
a body having a flat surface; and
a plurality of open grooves formed in the flat surface of said body;
wherein each of said plurality of open grooves further comprises:
sides that extend within said body and from said flat surface of said body; and
a rounded contour at the bottom of said sides, said rounded contour having a cross section with a radius that matches said outside radius of said selected tubular instrument to within plus or minus 10%; and
wherein said sides and said rounded contour of said open groove have a combined depth greater than the outside diameter of said selected tubular medical instrument;
wherein at least two of said plurality of open grooves includes first portions having shallower depths than second portions, said first portion of said groove having a first rounded contour with a smaller radius than a second rounded contour in said second portion of said groove, and wherein said at least two of said plurality of open grooves include a commonly-sized first rounded contour;
wherein a different rounded contour is formed in each of at least two of said plurality of grooves, said different contours corresponding to the outside radii of a plurality of different sized selected tubular medical instruments; and
an attachment mechanism coupled to the body, the attachment mechanism for securing the body to a fabric.
