International Classification:

A61M 3700

US Classification:

604131, 604151

Abstract:

A device for delivering fluid, such as insulin for example, to a patient. The device includes an exit port assembly, a syringe-like reservoir including a side wall extending towards an outlet connected to the exit port assembly. A threaded lead screw is received in the reservoir and a plunger has an outer periphery linearly slideable along the side wall of the reservoir and an inner periphery threadedly received on the lead screw. The plunger is non-rotatable with respect to the side wall such that rotating the lead screw causes the plunger to advance within the reservoir and force fluid through the outlet. The device also includes a dispenser having a return element for causes rotation of the lead screw, and a shape memory element. A changeable length of the shape memory element decreasing from an uncharged length to a charged length resets the return element.

International Classification:

A61M 3100

US Classification:

604131, 604 67

Abstract:

A device for delivering fluid, such as insulin, to a patient. The device includes an exit port assembly, a syringe-like reservoir including a side wall extending along a longitudinal axis towards an outlet connected to the exit port assembly, and a plunger assembly received in the reservoir. The plunger assembly includes a two-way shape memory element connecting first and second lateral segments, and having a changeable length decreasing from an uncharged length to a charged length when at least one charge is applied to the shape memory element. Successively applying a charge and removing the charge from the two-way shape memory element causes longitudinal movement of the plunger assembly towards the outlet of the reservoir in order to cause fluid to be dispensed from the reservoir to the exit port assembly.

International Classification:

A61M 25/10

US Classification:

60410306

Abstract:

The invention relates to a balloon catheter in which the balloon is mounted on the end of the catheter in a manner that creates a recess or pocket between the catheter wall and balloon wall. The recess or pocket opens toward the proximal end of the catheter. The rigid end of an introducer element or finger is received in the recess to attach it to the catheter. The distal end of the catheter, with the end of the introducer element in the recess, is inserted and positioned within the bowel by manipulating the introducer element or finger. After the catheter is properly positioned in the bowel, the introducer element or finger is withdrawn, detaching it from the catheter as the end of the introducer element slides out of the recess and then out of the bowel. The balloon is inflated prior to or after the withdrawal of the introducer element to anchor the end of the catheter in position within the bowel. Since the distal end of the catheter is made entirely of soft, compliant material, no soft tissue damage can occur from use of the device, even when the catheter remains in place within the body over an extended time period.
