Abstract

A system for delivering an implantable medical device to an implant location includes a control handle portion, a catheter portion coupled to the control handle portion, and a distal portion configured to receive the implantable medical device. The catheter portion includes outer shaft including an inner braided layer extending axially along the outer shaft, an outer braided layer extending axially along the outer shaft, wherein the outer braided layer has a lower density of braids relative to the inner braided layer, and an axial spine positioned between the inner braided layer and the outer braided layer extending axially along the outer shaft.

Claims22

Dependent claims

A system for delivering an implantable medical device to an implant location, the system comprising:

a control handle portion;
a catheter portion coupled to the control handle portion at a proximal end of the catheter portion, the catheter portion comprising an outer shaft, wherein the outer shaft comprises:
an inner braided layer extending axially along the outer shaft,
an outer braided layer extending axially along the outer shaft, wherein the outer braided layer has a lower density of braids relative to the inner braided layer, and
an axial spine positioned between the inner braided layer and the outer braided layer extending axially along the outer shaft;
and
a distal portion configured to receive the implantable medical device.

4 more elements

A system for delivering an implantable medical device to an implant location, the system comprising:

a control handle portion;
and
a catheter portion coupled to the control handle portion at a proximal end of the catheter portion, the catheter portion comprising an outer shaft, a capsule coupled to a distal end of the outer shaft, and an inner shaft;
and
a distal portion, the distal portion being configured to receive the implantable medical device between the inner shaft and the capsule,
wherein the capsule is actuatable to move axially from the distal portion to expose the implantable medical device and wherein the capsule is tubular shaped and comprises:
a ribbed member,
a jacket laminated to a portion the ribbed member, and
a flexibility region, the flexibility region having a stiffness that is less than other regions of the capsule due to delamination of the jacket from ribbed member in the flexibility region.
