Abstract
A medical system for coupling to a previously-introduced guidewire during an intracorporeal procedure comprises: a supplemental guide wire and a single-lumen tubular member comprising a radial wall fixedly engaged to a lengthwise portion of the supplemental guidewire The radial wall defines a passageway sized for slidable passage therethrough of the previously introduced guidewire. The tubular portion and the engaged lengthwise portion of the supplemental guidewire are not engaged coaxially.
Claims23
A medical system for coupling to a previously-introduced guidewire during an intracorporeal procedure, the medical system comprising:
- a. a supplemental guidewire;
- and
- b. a single-lumen tubular member comprising a radial wall fixedly engaged to a lengthwise portion of the supplemental guidewire, the radial wall defining a passageway sized for slidable passage therethrough of the previously introduced guidewire,
- wherein the tubular portion and the engaged lengthwise portion of the supplemental guidewire are not engaged coaxially.
The medical system of any one of the preceding claims, wherein a central longitudinal axis of the supplemental guidewire is laterally displaced from a central longitudinal axis of the tubular member.
The medical system of any one of the preceding claims, wherein a central longitudinal axis of the engaged lengthwise portion of the supplemental guidewire is parallel to and laterally displaced from a central longitudinal axis of the tubular member.
The medical system of any one of the preceding claims, wherein the engaged lengthwise portion of the supplemental guidewire is at least partly embedded longitudinally in the radial wall of the tubular member.
The medical system of any one of the preceding claims, wherein the fixed engaging of the tubular member with the lengthwise portion includes at least one of molding, overmolding, extruding, welding, heat-welding, gluing, soldering, and fusing.
The medical system of any one of the preceding claims, wherein the tubular member is molded and/or extruded to at least partly embed, in said radial wall, the lengthwise portion of the supplemental guidewire.
The medical system of any one of the preceding claims, wherein an angular majority of a circumference of the engaged lengthwise portion is in fixed contact with the radial wall.
The medical system of any one of the preceding claims, wherein at most an angular minority of a circumference of the engaged lengthwise portion is in fixed contact with the radial wall.
The medical system of any one of the preceding claims, wherein the engaged lengthwise portion of the supplemental guidewire includes a distal end of the supplemental guidewire.
The medical system of any one of the preceding claims, wherein the engaged lengthwise portion of the supplemental guidewire is not indestructibly separable from the tubular member.
A method of using multiple guidewires, the method comprising:
- a. providing the medical system of any one of the preceding claims;
- b. locating a proximal end of the previously-introduced guidewire;
- c. slidably passing the tubular member of the medical system over the proximal end of the previously-introduced guidewire so that said proximal end enters a distal opening of the tubular member and exits a proximal opening thereof;
- and
- d. distally advancing the medical system over the previously-introduced guidewire.
A method of coupling to a previously-introduced guidewire during an intracorporeal procedure, the method comprising:
- a. providing a medical system comprising a supplemental guidewire and a single-lumen tubular member comprising a radial wall fixedly and non-coaxially engaged with a lengthwise portion of the supplemental guidewire;
- b. locating a proximal end of a previously-introduced guidewire;
- c. slidably passing the tubular member of the medical system over the proximal end of the previously-introduced guidewire so that said proximal end enters a distal opening of the tubular member and exits a proximal opening thereof;
- and
- d. distally advancing the medical system over the previously-introduced guidewire.
