Abstract: A guide wire for guiding a medical device within a body lumen is described. The guide wire includes a proximal section, a distal section, and a mid section. The proximal section includes a proximal wire core tapered with contraction towards a proximal end of the proximal wire core. The distal section includes a distal wire core tapered with contraction towards a distal end of the distal wire core. The mid section includes a joint for joining the proximal wire core and the distal wire core. The guide wire also includes a safety wire extending along the mid section, and along at least parts of the proximal and distal sections. Moreover, the guide wire includes an outer tubing enveloping the overlapping joint and at least parts of the proximal and distal sections.

Abstract: A medical device is provided. The medical device includes a sheath with an extended distal end portion, a proximal end portion, and a lumen defined therethrough. A handle is fixedly connected to the proximal end portion of the sheath, the handle includes an operator that is translatable between a first position and a second position. A flow path is defined within the handle in fluid communication with the proximal end portion of the sheath, wherein the operator is configured to substantially block the flow path in a second position and allow flow therethrough in a first position. The flow path includes a portion that is configured to communicate with a remote source of suction. The handle additionally includes a second inlet portion configured to receive a tool therethrough and allow the tool to extend through the lumen of the sheath.
