Abstract
A puncture assembly for imaging-guided medical procedures to reach a target in deep tissues. The puncture assembly comprising, a tubular member having a wall enclosing a lumen and comprising a distal section extending up to a distal end of the tubular member, wherein the distal section is open on one side up to and including the distal end of the tubular member; and a core, slidably and rotatably disposed in the lumen of the tubular member and having a distal section, wherein the distal section is flexible and biased towards a curved shape.
Claims15
A puncture assembly comprising:
- a tubular member having a wall enclosing a lumen and comprising a distal section extending up to a distal end of the tubular member, wherein the distal section of the tubular member is open on one side up to and including the distal end of the tubular member and closed on another side up to and including the distal end of the tubular member;
- and
- a core slidably and rotatably disposed in the lumen of the tubular member and having a distal section, wherein the distal section is flexible and biased towards a curved shape, wherein the core is configured to reach out from the tubular member laterally.
A method for guiding a tubular member towards a target, the method comprising:
- providing the tubular member near the target, the tubular member having a wall enclosing a lumen and comprising a distal section extending up to a distal end of the tubular member wherein the distal section is open on one side up to and including the distal end of the tubular member and closed on another side up to and including the distal end of the tubular member
- providing a core in the lumen of the tubular member, the core having a distal section, wherein the distal section is flexible and biased to a curved shape, such that the biased distal section is biased towards the open side of the distal section;
- and sliding the core in the lumen of the tubular member until its distal section extends from the distal section of the tubular member according to its curved shape, wherein the core extends from the tubular member laterally.
