Abstract
Abstract An introducer system having an elongate shaft with proximal and distal ends. A flexible sleeve is mounted on the distal end of the shaft and is adapted to circumferentially cover the outer surface of a distal end of a cannula when the shaft is positioned within a lumen of the cannula. The introducer system has dilation capabilities which facilitates insertion of a medical device into a vessel or organ. Methods of using the devices herein are also disclosed.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
82 words
A cannula introducer system, comprising: a cannula having a proximal end, a distal end, and a lumen therebetween; an elongate shaft having proximal and distal ends, said shaft insertable through the lumen of the cannula; a flexible sleeve mounted on the distal end of the shaft, wherein the sleeve is adapted to circumferentially cover the distal end of the cannula when the shaft is positioned within the lumen of the cannula; and a filter operable from the distal end of the cannula.
Claim 2
Dependent Claim
82 words
A cannula introducer system, comprising: a cannula having a proximal end, a distal end, and a lumen therebetween; an elongate shaft having proximal and distal ends, said shaft insertable through the lumen of the cannula; a flexible sleeve mounted on the distal end of the shaft, wherein the sleeve is adapted to circumferentially cover the distal end of the cannula when the shaft is positioned within the lumen of the cannula; and a filter operable from the distal end of the cannula.
Claim 3
Dependent Claim
25 words
The cannula introducer system of claim 1 , wherein the proximal end of the cannula is adapted to receive oxygenated blood from a bypass-oxygenator machine.
Claim 4
Dependent Claim
16 words
The cannula introducer system of claim 1 , wherein the flexible sleeve is an elastomeric sleeve.
Claim 5
Dependent Claim
15 words
The cannula introducer system of claim 1 , wherein the sleeve comprises a lubricious material.
Claim 6
Dependent Claim
14 words
The cannula introducer system of claim 1 , wherein the elongate shaft is flexible.
Claim 7
Dependent Claim
16 words
The cannula introducer system of claim 1 , wherein the elongate shaft further comprises a coil.
Claim 8
Dependent Claim
20 words
The cannula introducer system of claim 1 , further comprising a collet at the proximal end of the elongate shaft.
Claim 9
Dependent Claim
28 words
The cannula introducer system of claim 1 , further comprising an angulated tip adapted for insertion into a body tissue at the distal end of the elongate shaft.
Claim 10
Dependent Claim
13 words
The cannula introducer system of claim 1 , wherein the filter is expandable.
Claim 11
Dependent Claim
15 words
The cannula introducer system of claim 1 , wherein the filter comprises a mesh material.
Claim 12
Dependent Claim
15 words
The cannula introducer system of claim 1 , wherein the sleeve circumferentially covers the filter.
Claim 13
Dependent Claim
20 words
The cannula introducer system of claim 1 , wherein the filter is mounted on the distal end of the cannula.
Claim 14
Independent Claim
71 words
A method for protecting a patient from embolization during an open or minimally invasive surgical procedure, comprising: inserting a distal end of a cannula into the aorta, the cannula having a lumen, an expandable filter mounted at the distal end, and a flexible sleeve covering the filter; removing the sleeve from the expandable filter through the lumen of the cannula; and expanding the filter to capture embolic material in the aorta.
Claim 15
Independent Claim
71 words
A method for protecting a patient from embolization during an open or minimally invasive surgical procedure, comprising: inserting a distal end of a cannula into the aorta, the cannula having a lumen, an expandable filter mounted at the distal end, and a flexible sleeve covering the filter; removing the sleeve from the expandable filter through the lumen of the cannula; and expanding the filter to capture embolic material in the aorta.
Claim 16
Dependent Claim
21 words
The method of claim 13 , wherein the distal end of the cannula is inserted into the aorta through an incision.
Claim 17
Dependent Claim
26 words

Claim 18
Dependent Claim
13 words
The method of claim 13 , wherein the sleeve comprises a lubricious material.
Claim 19
Dependent Claim
14 words
The method of claim 13 , wherein the cannula connects to a bypass-oxygenator machine.
Claim 20
Dependent Claim
19 words
