Beschreibung
Zusammenfassung:	A lead introducer includes an outer needle with a sharpened distal tip and an open channel extending along an entire length of the outer needle. An inner needle slides along the open channel of the outer needle. The inner needle includes a blunt distal tip. A biasing element is coupled to the inner needle and facilitates transition of the inner-needle distal tip between a distally-biased position, where the inner-needle distal tip obstructs the sharpened outer-needle distal tip, and a retracted position, where the inner-needle distal tip exposes the sharpened outer-needle distal tip. A splittable member is disposable over the outer needle when the inner needle is disposed in the open channel of the outer needle. The splittable member is separatable from the inner and outer needles along at least one perforated region.
