Abstract
An endoluminal needle or punch is describes wherein the distal end of the endoluminal needle is able to articulate laterally out of the longitudinal axis of the steerable endoluminal needle. The endoluminal needle further comprise a blunted distal end configuration that is minimally traumatic. Under control by the user, at the proximal end of the endoluminal needle, a sharp stylet can be advanced to punch tissue and then be retracted to maximize safety. The endoluminal needle is configured for use within an introducer.
Claims20
A device for penetrating a body lumen or hollow organ of a mammal comprising:
- an outer tube, said outer tube characterized by a distal end, and proximal end, and an outer tube lumen extending from the distal end to the proximal end thereof, said outer tube having a flexible region near the distal end of the outer tube;
- a first control rod disposed with the outer tube, said first control characterized by a distal end and a proximal end;
- wherein the control rod is fixed to the distal end of the outer tube and extends proximally to the proximal end of the outer tube;
- and
- a second control rod disposed with the outer tube, said first control characterized by a distal end and a proximal end;
- wherein the control rod is fixed to the distal end of the outer tube and extends proximally to the proximal end of the outer tube;
- wherein
- the first control rod and the second control rod comprise partial cylinders disposed coaxially within the outer tube.
A device for penetrating a body lumen or hollow organ of a mammal comprising:
- an outer tube, said outer tube characterized by a distal end, and proximal end, and an outer tube lumen extending from the distal end to the proximal end thereof, said outer tube having a flexible region near the distal end of the outer tube;
- a control rod disposed with the outer tube, said control characterized by a distal end, and proximal end;
- wherein the control rod is fixed to the distal end of the outer tube and extends proximally to the proximal end of the outer tube, and includes a portion disposed within the flexible region of the outer tube;
- and
- wherein the portion disposed within the flexible region of the outer tube comprises a partial cylinder;
- and
- a keeper, comprising a partial cylinder, disposed within the outer tube, in the flexible region, and disposed radially displaced from the partial cylinder of the control rod, wherein said keeper is not fixed directly to the control rod.
An apparatus adapted for punching a hole in a body lumen or hollow organ of a mammal comprising:
- an outer tube having a proximal end, a distal end, a longitudinal axis, and a lumen extending therethrough, and a flexible region proximate the distal end;
- an inner tube disposed within the outer tube, said inner tube comprising a partial cylinder along a portion of its length, extending from the proximal end of the outer tube to the proximal end of the flexible region;
- a control rod disposed within the lumen of the outer tube, said control rod extending from the inner tube through the flexible region of the outer tube, said control rod longitudinally fixed to distal end of the inner tube and longitudinally fixed to the outer tube at a point distal to the flexible region;
- a hub comprising a first portion longitudinally affixed to the proximal end of the inner tube, and a second portion affixed to proximal end of the outer tube, and said first and second portions are movable relative to each other to tension the inner tube relative to the outer tube.
