Abstract
An introducing apparatus is provided which includes an elongate tubular sheath extending from a sheath proximal end to a sheath distal end. The sheath has a bore sized to receive a dilator therethrough. The sheath further includes at least one tab extending away from a longitudinal axis of the sheath. The dilator extends from a dilator proximal end to a dilator distal end. The introducing apparatus further includes a needle disposed within the dilator, and retractably coupled with the dilator. A distal end of the needle is flexible.
Claims30
An introducing apparatus comprising:
- an elongate tubular sheath extending from a sheath proximal end to a sheath distal end, the sheath having a bore including an internal diameter sized to receive a dilator therethrough, the internal diameter sized to receive medial instruments therethrough;
- the dilator extending from a dilator proximal end to a dilator distal end;
- a needle disposed within the dilator, the needle extending from a needle proximal end to a needle distal end and including an intermediate portion therebetween, the intermediate portion is flexible;
- the needle distal end extending out of the dilator distal end in a first position, the needle distal end retracted within the dilator distal end in a second position;
- and
- a needle retraction mechanism coupled with the needle and the dilator, and the needle is retractably coupled with the dilator.

- the sheath including at least one tab extending away from a longitudinal axis of the sheath;
- the dilator extending from a dilator proximal end to a dilator distal end;
- a needle disposed within the dilator, the needle extending from a needle proximal end to a needle distal end and including an intermediate portion therebetween, at least the needle distal end is flexible;
- the needle distal end extending out of the dilator distal end in a first position, the needle distal end retracted within the dilator distal end in a second position;
- and
- a needle retraction mechanism coupled with the needle and the dilator, and the needle is retractably coupled with the dilator.
A method comprising:
- disposing a needle within a dilator,
- retractably coupling said needle with said dilator, the dilator extending to a dilator distal end, where the needle extends to a needle distal end and the needle distal end is more flexible than the dilator, and the needle distal end extends beyond the dilator distal end;
- disposing the needle and dilator within a sheath to form an introducing apparatus;
- and
- inserting the introducing apparatus into a body.
