Abstract
The invention provides devices with specialized ends for diverting fluids trapped in an organ. In a first group of embodiments, the invention provides implantable devices that shunt fluid trapped in a patient's organ to its normal physiological destination. In a second group of embodiments, the invention provides devices with specialized ends for connecting the devices to conventional medical tubing to divert fluid trapped in an organ to a destination selected by the practitioner. The invention further provides systems and methods of using the devices.
Claims62
An implantable medical device to provide fluid communication between two body cavities, said device comprising a body and a second end protector, wherein
- (a) said body is tubular and has a transverse axis having a diameter, is permeable or impermeable, has a first end and a second end and has a lumen fluidly connecting said first and second ends and,
- (b) said second end protector extends from said second end of said body, has a first end joined to said second end of said body and fluidly connected to said lumen, has a longitudinal axis, has a second end disposed opposite said first end of said second end protector along said longitudinal axis, has a transverse axis having a diameter, wherein said second end protector is permeable along at least part of said longitudinal axis, and wherein said second end protector is rigid or expansile.
A method of relieving pressure on a patient's organ due to trapped fluid, said method comprising implanting in said organ a device to divert said trapped fluid from said organ to an adjacent body cavity, said device comprising a body and a second end protector, wherein
- (a) said body is tubular and has a transverse axis having a diameter, is permeable or impermeable, has a first end and a second end and has a lumen fluidly connecting said first and second ends, and,
- (b) said second end protector extends from said second end of said body, has a first end joined to said second end of said first section and fluidly connected to said lumen, has a longitudinal axis, has a second end disposed opposite said first end of said second end protector along said longitudinal axis, has a transverse axis having a diameter, wherein said second end protector is permeable along at least part of said longitudinal axis and wherein said second end protector is rigid or expansile.
An implantable device for transferring fluid from a patient's organ, said device comprising:
- a tubular body having a longitudinal axis and a lumen, which body has
- (i) a first section having a first end and a second end at opposite ends of said longitudinal axis and a transverse axis expandable from a first diameter to a second, larger diameter,
- (ii) a second section extending from said first section along said longitudinal axis and having a first end and a second end having respective diameters, wherein the diameter of said second end is smaller than the diameter of said first end, and
- (iii) a lumen fluidly connecting said first end of said first section to said second end of said second section.
A system for transferring fluid from a patient's brain, said system comprising:
- (a) a device having a tubular body with a longitudinal axis and a lumen, which body has
- (i) a first section having a first end and a second end at opposite ends of said longitudinal axis and a transverse axis expandable from a first diameter to a second, larger diameter,
- (ii) a second section extending from said first section along said longitudinal axis and having a first end and a second end having respective diameters, wherein the diameter of said second end is smaller than the diameter of said first end, and
- (iii) a lumen fluidly connecting said first end of said first section to said second end of said second section, and
- (b) a skull port piece.
