Medical device with improved wire guide access
First Claim
1. A medical apparatus to be used in combination with a medical wire guide, comprising:
- a handle assembly that includes a side port assembly comprising at least a first port and a second port;
a catheter portion attached to the handle assembly, the catheter portion including at least a first and a second lumen extending at least partially therethrough;
a first pathway adapted for the delivery of a fluid therethrough, the first pathway communicating with the first port;
a second pathway adapted for accommodating the medical wire guide, the second pathway communicating with the second port;
a third pathway extending distally from the handle assembly through the second lumen, the third pathway adapted to permit remote operation of a working member located about the distal end of the catheter portion; and
wherein the second port includes a sealing mechanism adapted to seal around the wire guide when placed therein, and substantially preventing the loss of fluid from the second port, and wherein the first and second pathways each extend through the first lumen, such that the wire guide can be placed and remain within the second pathway while the fluid comprising the first pathway is infused therethrough.

Abstract
Disclosed is a medical apparatus assembly (10) comprising a medical device (11) that includes a side port assembly 13 adapted to combine a first pathway (37) for infusion of fluids with a second pathway (38) for wire guide (12) into a first passageway (26) while the second passageway (27) includes the third pathway (39), which comprises a control member (24), such as an electrical wire. The side port assembly is configured such that the first passageway communicates with both a first port (16), such as a fitting for connecting to a syringe, and a second port (15) which includes a sealing mechanism (32), such as a Tuohy-Borst fitting, thereby allowing the wire guide to be preloaded, instead of requiring it to be removed prior to infusing fluids. Optionally, a third port (43) may be included when external communication with the second passageway, is desired, such as balloons or baskets.
