Abstract
Abstract An apparatus for steering a guidewire and for connecting the guidewire to an extension guidewire. The apparatus includes a steering device for gripping an exterior of the guidewire, the steering device defining a passageway therein through which the guidewire may pass; and a connecting device for connecting the guidewire to the extension guidewire. The connecting device is configured for mating with the steering device to form an integral unit. The invention further includes a method of inserting a guidewire in a body and connecting the guidewire to an extension guidewire. The method includes the steps of: providing an integral guidewire holder and tool for connecting a guidewire to an extension guidewire; gripping the guidewire with the integral guidewire holder; inserting the guidewire into a body lumen; displacing the integral guidewire holder and tool relative to the guidewire so that the proximal end of the guidewire is located in a slot of the integral guidewire holder and tool; inserting an extension guidewire into the slot of the integral guidewire holder and tool; and connecting the guidewire to the extension guidewire. The method further includes the step of aligning the guidewire and extension guidewire in the slot prior to the connecting step.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
127 words
An apparatus for steering a guidewire and for connecting the guidewire to an extension guidewire, comprising: a steering device for gripping an exterior of the guidewire, the steering device defining a passageway therein through which the guidewire may pass; and a connecting device configured to connect the guidewire to the extension guidewire, said connecting device configured for mating with said steering device to form an integral unit, wherein said connecting device defines a longitudinal slot located on a substantially flat surface configured to align the guidewire with the extension guidewire, and wherein said connecting device further includes a longitudinal passageway which extends from a distal end of the connecting device adjacent the steering device to the longitudinal slot on the substantially flat surface of the connecting device.
Claim 2
Independent Claim
127 words
An apparatus for steering a guidewire and for connecting the guidewire to an extension guidewire, comprising: a steering device for gripping an exterior of the guidewire, the steering device defining a passageway therein through which the guidewire may pass; and a connecting device configured to connect the guidewire to the extension guidewire, said connecting device configured for mating with said steering device to form an integral unit, wherein said connecting device defines a longitudinal slot located on a substantially flat surface configured to align the guidewire with the extension guidewire, and wherein said connecting device further includes a longitudinal passageway which extends from a distal end of the connecting device adjacent the steering device to the longitudinal slot on the substantially flat surface of the connecting device.
Claim 3
Dependent Claim
34 words
The apparatus of claim 1 , wherein the distal end of the connecting device adjacent the steering device includes a conical opening for guiding the guidewire into the longitudinal passageway of the connecting device.
Claim 4
Dependent Claim
42 words
The apparatus of claim 1 , wherein a proximal end of the connecting device farthest from the steering device includes a partial conical opening for guiding the extension guidewire into the longitudinal slot on the substantially flat surface of the connecting device.
Claim 5
Independent Claim
139 words
An apparatus for steering a guidewire and for connecting the guidewire to an extension guidewire, comprising: a steering device for gripping an exterior of the guidewire, the steering device defining a passageway therein through which the guidewire may pass; and a connecting device for connecting the guidewire to the extension guidewire, said connecting device configured for mating with said steering device to form an integral unit, wherein said configured device defines a longitudinal slot located on a substantially flat surface for aligning the guidewire with the extension guidewire, and wherein said connecting device further includes a longitudinal passageway which extends from a distal end of the connecting device adjacent the steering device to the longitudinal slot on the substantially flat surface of the connecting device, wherein the substantially flat surface further includes a transverse channel intersecting said longitudinal slot.
Claim 6
Independent Claim
139 words
An apparatus for steering a guidewire and for connecting the guidewire to an extension guidewire, comprising: a steering device for gripping an exterior of the guidewire, the steering device defining a passageway therein through which the guidewire may pass; and a connecting device for connecting the guidewire to the extension guidewire, said connecting device configured for mating with said steering device to form an integral unit, wherein said configured device defines a longitudinal slot located on a substantially flat surface for aligning the guidewire with the extension guidewire, and wherein said connecting device further includes a longitudinal passageway which extends from a distal end of the connecting device adjacent the steering device to the longitudinal slot on the substantially flat surface of the connecting device, wherein the substantially flat surface further includes a transverse channel intersecting said longitudinal slot.
Claim 7
Dependent Claim
21 words
The apparatus of claim 4 , wherein the transverse channel has a depth greater than the depth of the longitudinal slot.
