Abstract
Example access sheaths are disclosed. An example access sheath for a medical device includes an elongate shaft having a distal end region, a proximal end region and a wall. Further, the access sheath includes a hub coupled to the proximal end region of the elongate shaft and a first pull cord coupled to the hub, wherein the first pull cord is configured to translate along the elongate shaft from the proximal end region to the distal end region. Further, translation of the first pull cord along the elongate shaft cuts the wall of the elongate shaft from the proximal end region to the distal end region.
Claims20
An access sheath for a medical device, comprising:
- an elongate shaft having a distal end region, a proximal end region and a wall;
- a hub coupled to the proximal end region of the elongate shaft;
- and
- a first pull cord coupled to the hub, wherein the first pull cord is configured to translate along the elongate shaft from the proximal end region to the distal end region;
- wherein translation of the first pull cord along the elongate shaft cuts the wall of the elongate shaft from the proximal end region to the distal end region.
An access sheath for a medical device, comprising:
- an elongate shaft having a distal end region, a proximal end region and a wall;
- a hub coupled to the proximal end region of the elongate shaft, wherein the hub includes a first hub member configured to separate from a second hub member;
- a pull cord coupled to the hub, wherein the pull cord is configured to translate along the elongate shaft from the proximal end region to the distal end region;
- wherein translation of the pull cord along the elongate shaft cuts the wall of the elongate shaft from the proximal end region to the distal end region.
A method for advancing a medical device into a body lumen, comprising:
- positioning an access sheath adjacent a body lumen, the access sheath comprising:
- an elongate shaft having a distal end region, a proximal end region and a wall;
- a hub coupled to the proximal end region of the elongate shaft;
- and
- a pull cord attached to the hub, the pull cord configured to cut the wall of the elongate shaft;
- advancing the medical device through the access sheath and into the body lumen;
- translating the pull cord along the elongate shaft from the proximal end region to the distal end region, wherein translation of the pull cord along the elongate shaft cuts the wall of the elongate shaft from the proximal end region to the distal end region;
- and
- removing the access sheath from the medical device via passing at least a portion of the medical device through the cut portion of the elongate shaft.
