An inserter, system and method for inserting an IOL may include a lumen having an outer wall and an inner wall that includes at least one hollowed portion; a plunger for advancing along the lumen and having a plunger shaft extending into an open proximal end and terminating at a distal plunger end; a reservoir within the lumen between the distal plunger end and the distal insertion tip, having an opening that is misaligned with the at least one hollowed portion prior to advancing of the plunger, and that is aligned with the at least one hollowed portion during advancing of the plunger; and a viscous fluid within the lumen that flows along a bypass formed of the at least one hollowed portion and the opening and into the reservoir, decreasing an inserting displacement force effected at the distal insertion tip from a plunger displacement force applied to said plunger.

Intraocular lens inserter and system and method regarding same

A system and method for the use of magneto-rheological fluids (MRF) and magnetically controlled elastomers (MCE) for use in fluid control and distribution apparatus which are responsive to control by a magnetic field are disclosed.

Magnetically controlled stiffness of materials

Balloon catheter includes an elongate tubular shaft having an outer tubular member having proximal and distal portions, and an inner tubular member having a distal length extending distally from the distal portion of the outer tubular member. The elongate tubular shaft has an inflation lumen and a guidewire lumen defined therein. The guidewire lumen extends along at least the distal length of inner tubular member. The balloon catheter also includes a distal end section coupled to a distal end of the inner tubular member and having a proximal end and a distal end. The balloon catheter also includes a balloon having a proximal portion sealingly coupled to the distal portion of the outer tubular member, a distal portion sealingly coupled to the distal end section, and a working length therebetween. The balloon defines an inner chamber. The proximal end of the distal end section is disposed within the inner chamber.

Catheter having transitioning shaft segments

The present inserter, system and method suitable for inserting the IOL may include a lumen having an outer wall and an inner wall, the inner wall including at least one hollowed portion; a plunger for advancing along the lumen, the plunger having a plunger shaft extending into the open proximal end and terminating at a distal plunger end; a reservoir within the lumen between the distal plunger end and the distal insertion tip, the reservoir having an opening that is misaligned with the at least one hollowed portion prior to advancing of the plunger, and that is aligned with the at least one hollowed portion during advancing of the plunger; and a viscous fluid within the lumen, wherein the viscous fluid flows along a bypass formed of the at least one hollowed portion and the opening and into said reservoir, thereby decreasing an inserting displacement force effected at the distal insertion tip from a plunger displacement force applied to said plunger.

A catheter having shaft segments which are joined together by a strong bond providing a low profile shaft section with a flexibility transition and/or a compositional transition. A balloon catheter embodying features of the invention has a distal tip member and a coupling band member surrounding a junction of an inner tubular member of the shaft, and has a gradual change in bending stiffness along a distal end section of the shaft which extends distally from a location within the balloon interior. Another catheter embodying features of the invention has shaft segments joined together by a diagonal seam.
