Abstract

A medical implant delivery system can comprise a puncture needle, a medical implant delivery catheter and the puncture needle being configured to be slidably advanced through a puncture needle lumen of the medical implant delivery catheter, a medical implant device positioned on the medical implant delivery catheter, and an outer delivery catheter comprising a medical implant delivery lumen, the medical implant delivery catheter being configured to slidably extend through the medical implant delivery lumen. A medical implant delivery system can comprise a puncture needle, a medical implant delivery catheter and the puncture needle being configured to slidably extend through the puncture needle lumen of the medical implant delivery catheter, a medical implant device positioned on the medical implant delivery catheter, an elongate housing adjacent to the medical implant delivery catheter, and an outer sheath around a portion of the medical implant delivery catheter and the elongate housing.

Claims18

Dependent claims

A medical implant delivery system comprising:

a puncture needle comprising an elongate portion and a puncture component associated with a distal end of the elongate portion, the puncture component being configured to pierce and form an opening in a target tissue wall;
a medical implant delivery catheter comprising a puncture needle lumen, the puncture needle being configured to be advanced through the puncture needle lumen, the puncture component being configured to be extended through a puncture needle outlet opening associated with a distal portion of the medical implant delivery catheter;
a deployable medical implant device separably positioned on the medical implant delivery catheter, the deployable medical implant device being adapted to remain implanted after withdrawal of the medical implant delivery catheter;
an outer delivery catheter comprising a medical implant delivery lumen, the medical implant delivery catheter being configured to be advanced through the medical implant delivery lumen, the distal portion of the medical implant delivery catheter being configured to be received within the medical implant delivery lumen and extended through a side outlet opening associated with a distal portion of the outer delivery catheter,
wherein a distal portion of the medical implant delivery catheter comprises a first pre-formed curvature, a distal portion of the outer delivery catheter comprises a second pre-formed curvature, and a distal portion of the puncture needle comprises a third pre-formed curvature, and the third pre-formed curvature having a radius of curvature smaller than that of the first pre-formed curvature,
wherein the distal portion of the medical implant delivery catheter comprises a lateral cross section having a shape that matches a shape of the side outlet opening on the distal portion of the outer delivery catheter to orient the medical implant delivery catheter as the medical implant delivery catheter extends through the side opening, and were in a lateral cross section of a proximal portion of the medical implant delivery catheter is without the shape;
and
a proximal handle engaged with the medical implant delivery catheter and the outer delivery catheter, and comprising an advancer translatable distally to advance the medical implant delivery catheter and the outer delivery catheter.

A medical implant delivery system comprising:

a medical implant delivery catheter comprising a puncture needle lumen extending therethrough and a distal portion having a first pre-formed curvature;
a deployable medical implant device separably and circumferentially positioned around the first pre-formed curvature of the medical implant delivery catheter, the deployable medical implant device being adapted to remain implanted after withdrawal of the medical implant delivery catheter;
and
an outer delivery catheter comprising:
a distal portion having a second pre-formed curvature, at least a portion of the medical implant delivery catheter configured to be disposed through a medical implant delivery lumen of the outer delivery catheter and be advanced out of a side outlet opening on the second pre-formed curvature, and
a guide wire lumen extending through the outer delivery catheter off-set from a central longitudinal axis of the outer delivery catheter;
and
a proximal handle engaged with the meidcal implant delivery catheter and the outer delivery catheter, and comprising an advancer translatable distally to advance the medical implant delivery catheter and the outer delivery catheter,
wherein the distal portion of the medical implant delivery catheter comprises a lateral cross section having a shape that matches a shape of the side outlet opening on the distal portion of the outer delivery catheter to orient the medical implant delivery catheter as the medical implant delivery catheter extends through the side opening, and were in a lateral cross section of a proximal portion of the medical implant delivery catheter is without the shape.
