Abstract

A medical system includes a handle, a sheath extending from the handle, and an end effector connected to a distal end of the sheath, where the end effector directs a mass of material towards a target site of a body and cause release of the material onto the target site.

First claim

What is claimed is:

1. A medical system, comprising:
a handle;
a sheath extending from a distal end of the handle;
a catheter including a catheter lumen, wherein the sheath is configured to extend through the catheter lumen;
a capsule containing a material, wherein the capsule includes a tether, the tether is woven through a wall of the capsule; and
an end effector connected to a distal end of the sheath and configured to grasp the tether,
wherein the end effector is configured to advance the capsule along the catheter lumen and to a target site via a catheter lumen opening at a distal end of the catheter, wherein an outer portion of the capsule includes a material configured to adhere to the target site when exposed to a fluid, and wherein the end effector is configured to cause release of the material from the capsule and onto the target site by applying a force on the tether once the capsule is adhered to the target site;
wherein the capsule includes a first side and a second side configured to separate from the first side; and
wherein the tether and the capsule are configured so that applying force to the tether separates the first side from the second side.

2. The medical system according to claim 1 , wherein the distal end of the catheter or the sheath is configured to bend when the distal end of the sheath is distal of a distalmost end of the catheter.

3. The medical system of claim 1 , wherein the material is a hemostatic powder or a therapeutic powder.
