Abstract
Various concepts relate to treatment systems for medical devices delivered into patients in medical procedures. The treatment system may include a proximal valve configured to receive the endoluminal device, an optional distal valve configured to receive the endoluminal device, and a treatment chamber configured to receive a portion of the endoluminal device.
Claims27
A treatment system comprising:
- an endoluminal device having a sleeve extending about a body of the endoluminal device;
- a proximal valve configured to receive the endoluminal device, the proximal valve including a proximal seal mechanism actuatable between a sealed state and an unsealed state to seal around the endoluminal device;
- a distal valve configured to receive the endoluminal device, the distal valve including a distal seal mechanism actuatable between a sealed state and an unsealed state around the endoluminal device;
- a sheath extending distally of the distal valve;
- and
- a treatment chamber configured to receive a treatment portion of the endoluminal device that extends between the proximal valve and the distal valve such that a sleeve maintaining the treatment portion in a compacted, delivery state extends through a portion of the proximal valve and into the treatment chamber, the treatment chamber being fluidly coupled between the proximal valve and the distal valve to define a treatment space between the proximal valve and the distal valve,
- wherein the treatment system defines a length including the proximal valve, the distal valve, the sheath and the treatment chamber, the treatment system further having an inner lumen extending along the length of the treatment system, and
- wherein the proximal valve is sealable about the endoluminal device such that a treatment medium exits the treatment chamber through one or more gaps between the sleeve and the body of the endoluminal device and through the proximal valve when the proximal valve is closed about the endoluminal device.

A method of treating an endoluminal device for introduction into a body of a patient, the method comprising:
- positioning the endoluminal device into a treatment system, the treatment system including a proximal valve, a distal valve, and a treatment chamber defining a treatment space between the proximal valve and the distal valve, the endoluminal device including a first portion extending through the proximal valve, a second portion extending through the distal valve, and a treatment portion extending through the treatment space of the treatment chamber, wherein at least a portion of the first portion is maintained in a compacted delivery state by a sleeve, and the sleeve extends through at least a portion of the proximal valve and the proximal valve is closed over the sleeve;
- closing the proximal and distal valves to seal the proximal valve against the first portion of the endoluminal device and the distal valve against the second portion of the endoluminal device;
- and
- delivering a treatment medium into the treatment space to expose the treatment portion of the endoluminal device to the treatment medium, wherein the treatment medium exits the treatment chamber through one or more gaps between the sleeve and a body of the endoluminal device and through the proximal valve when the proximal valve is closed.

A method of treating an endoluminal device for introduction into a body of a patient, the method comprising:
- positioning the endoluminal device into a treatment system, the endoluminal device having a distal end and the treatment system including a valve and a treatment chamber extending from the valve, the endoluminal device including a first portion extending through the valve and a treatment portion extending into the treatment space of the treatment chamber, the distal end of the endoluminal device being positioned within the treatment chamber such that a sleeve maintaining at least a portion of the endoluminal device in a compacted delivery state extends through a portion of the valve and into the treatment chamber;
- closing the valve to seal the valve against the first portion of the endoluminal device including the sleeve;
- sealing the treatment system when the distal end of the endoluminal device is within the treatment chamber;
- and
- delivering a treatment medium into a treatment space within the treatment chamber to expose the treatment portion of the endoluminal device to the treatment medium, wherein the treatment medium exits the treatment chamber through one or more gaps between the sleeve and a body of the endoluminal device and through the valve when the valve is closed.
2 more elements
A treatment system for an endoluminal device comprising:
- a valve configured to receive at least a portion of the endoluminal device;
- and
- a treatment chamber extending from the valve and including a treatment space containing a treatment medium, the treatment chamber configured to receive a treatment portion of the endoluminal device such that a sleeve maintaining the treatment portion in a compacted, delivery state extends through a portion of the valve and into the treatment chamber and is sealed to the valve,
- wherein at least a portion of the treatment medium exits the lumen of the treatment chamber through one or more gaps between the sleeve and the endoluminal device and through the valve when the valve is closed.
