Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
131 words
A catheter, comprising: a. a catheter body defining a central longitudinal lumen; b. an inflatable balloon positioned proximate a distal end of the catheter body and in fluid flow communication with the central longitudinal lumen; c. a sheath positioned proximate the distal end of the catheter, distal the inflatable balloon and fixedly coupled to the catheter body and distally extensible therefrom; d. a guidewire shaft positioned co-axially within the central longitudinal lumen of the catheter body and passing through an entire longitudinal length of the catheter body; and e. an annular plug member concentrically coupled to the guidewire shaft and positioned distal the inflatable balloon and proximal the sheath, the annular plug member terminating the central longitudinal lumen of the catheter body in a fluid tight manner and being moveable therein.
Claim 2
Dependent Claim
131 words
A catheter, comprising: a. a catheter body defining a central longitudinal lumen; b. an inflatable balloon positioned proximate a distal end of the catheter body and in fluid flow communication with the central longitudinal lumen; c. a sheath positioned proximate the distal end of the catheter, distal the inflatable balloon and fixedly coupled to the catheter body and distally extensible therefrom; d. a guidewire shaft positioned co-axially within the central longitudinal lumen of the catheter body and passing through an entire longitudinal length of the catheter body; and e. an annular plug member concentrically coupled to the guidewire shaft and positioned distal the inflatable balloon and proximal the sheath, the annular plug member terminating the central longitudinal lumen of the catheter body in a fluid tight manner and being moveable therein.
Claim 3
Dependent Claim
33 words
The catheter of claim 1 , further comprising a valve stent member, in a reduced diametric state, positioned within the sheath and concentrically about the guidewire shift and distal the annular plug member.
Claim 4
Dependent Claim
17 words
The catheter of claim 1 , further comprising a delivery profile of 12 French size or smaller.
Claim 5
Dependent Claim
26 words
The catheter of claim 2 , wherein the annular plug member retains the position of the valve stent as the catheter is withdrawn in retrograde fashion.
Claim 6
Dependent Claim
124 words
A catheter comprising: a. a catheter body defining a central longitudinal lumen, the catheter body comprises a distal stent capturing section; b. an inflatable balloon positioned proximate the distal stent capturing section of the catheter body and in fluid flow communication with the central longitudinal lumen; c. a guidewire shaft positioned co-axially within the central longitudinal lumen of the catheter body and passing through an entire longitudinal length of the catheter body; and d. an annular plug member concentrically coupled to the guidewire shaft and positioned distal the inflatable balloon and proximal the distal stent capturing section, the annular plug member terminating the central longitudinal lumen of the catheter body in a fluid tight manner and being moveable within the distal stent capturing section.
Claim 7
Dependent Claim
124 words
A catheter comprising: a. a catheter body defining a central longitudinal lumen, the catheter body comprises a distal stent capturing section; b. an inflatable balloon positioned proximate the distal stent capturing section of the catheter body and in fluid flow communication with the central longitudinal lumen; c. a guidewire shaft positioned co-axially within the central longitudinal lumen of the catheter body and passing through an entire longitudinal length of the catheter body; and d. an annular plug member concentrically coupled to the guidewire shaft and positioned distal the inflatable balloon and proximal the distal stent capturing section, the annular plug member terminating the central longitudinal lumen of the catheter body in a fluid tight manner and being moveable within the distal stent capturing section.
Claim 8
Dependent Claim
17 words
The catheter of claim 5 , further comprising a delivery profile of 12 French size or smaller.
Claim 9
Dependent Claim
27 words
The catheter of claim 5 , wherein the annular plug member maintains the position of the valve stent as the catheter is withdrawn in a retrograde fashion.
