Abstract

A delivery cartridge, delivery system and a method for delivering a medical device are provided. The delivery cartridge includes a housing having a proximal end, a distal end and a cavity defined therein. The delivery cartridge further includes a proximal end covering member connected to the proximal end, a distal end covering member connected to the distal end, and a medical device positioned within the cavity. The housing is adapted to fit within a lumen of a delivery system.

Claims

1. A delivery cartridge for a medical device, the delivery cartridge comprising:

a housing including a proximal end and a distal end, the housing having a cavity defined therein, the housing adapted to fit within a lumen of a delivery system;

a proximal end covering member connected to the proximal end;

a distal end covering member connected to the distal end; and

a medical device positioned within the cavity.

2. The delivery cartridge of claim 1, further comprising a lumen extending between the proximal end and the distal end.

3. The delivery cartridge of claim 1, wherein the cavity is configured to provide a fluidly sealed region configured to receive a hydrating fluid, the lumen being separate from the cavity.

4. The delivery cartridge of claim 3, further comprising a hydrating fluid within the cavity.

5. The delivery cartridge of claim 1, wherein the medical device within the cavity is sterile.

6. The delivery cartridge of claim 1, wherein at least one of the proximal end covering member or the distal end covering member comprises a frangible portion.

7. The delivery cartridge of claim 1, wherein at least one of the proximal end covering member or the distal end covering member is removably connected to the housing.

8. The delivery cartridge of claim 1, wherein the medical device is a stent.

9. The delivery cartridge of claim 1, wherein the medical device comprises a hydratable material.

16. The delivery system of claim 9, further comprising a plurality of cartridges positioned within the first lumen.

17. The delivery system of claim 9, further comprising a wire guide insertable through a lumen of the delivery cartridge.

10. A delivery system for delivering a medical device to a body site, the system comprising:

an outer sheath comprising a proximal portion, a distal portion and a first lumen extending at least partially through the sheath;

an inner shaft slidably received within the first lumen; and

a delivery cartridge positionable within a distal portion of the first lumen, the delivery cartridge comprising;

a housing including a proximal end, a distal end and a cavity defined within the housing, the cavity configured to receive a medical device for delivery to a delivery site;

a proximal end covering member connected to the proximal end; and

a distal end covering member connected to the distal end,

wherein the inner shaft is configured to slide relative to the outer shaft to deliver the medical device to the delivery site while the housing remains in the first lumen during delivery.

11. The delivery system of claim 10, further comprising a medical device positioned within the cavity.

12. The delivery system of claim 10, further comprising at least one protrusion extending into the first lumen at a distal end portion of the outer sheath, the protrusion configured to retain the housing in the lumen during delivery of the medical device.

13. The delivery system of claim 12, wherein the distal end portion including the at least one protrusion is removably connected to the outer sheath.

14. The delivery system of claim 11, wherein the inner shaft comprises a distal end having a pushing surface, the pushing surface configured to slide within the housing and contact the medical device to push the medical device to the delivery site.

15. The delivery system of claim 11, wherein the inner shaft comprises a distal tip, an intermediate portion and a proximal portion, the intermediate portion configured to receive the medical device and to advance the medical device to the delivery site.

18. A method of delivering a medical device to a delivery site, the method comprising:

providing a delivery system, the delivery system comprising;

an outer sheath comprising a proximal portion, a distal portion and a first lumen extending at least partially through the sheath;

an inner shaft slidably received within the first lumen; and

a delivery cartridge positionable within a distal portion of the first lumen, the delivery cartridge comprising;

a housing including a proximal end, a distal end and a cavity defined within the housing;

a proximal end covering member connected to the proximal end;

a distal end covering member connected to the distal end; and

a medical device positioned within the cavity;

advancing the delivery system to a delivery site;

deploying the medical device into the delivery site by sliding the inner shaft and the medical device relative to the outer sheath and the housing; and

withdrawing the inner shaft, the outer sheath and the housing.

19. The method of claim 18 further comprising positioning the delivery cartridge in the distal portion of the first lumen before advancing the delivery system to the delivery site.

20. The method of claim 18 wherein in the medical device is deployed by advancing a distal portion of the inner sheath through at least a portion of the housing to advance the medical device out of the housing and to the delivery site.
