Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
207 words
A balloon dilation catheter having an interior and an exterior, the catheter comprising: a. an elongate shaft having a proximal end, a distal end, and an inflation lumen extending therethrough; b. an inflatable balloon connected to the distal end of the elongate shaft, the balloon having a proximal end, a distal end and an interior in fluid communication with the inflation lumen; c. a proximal guide wire port providing access from the exterior of the catheter into the interior of the catheter at a location proximal of the proximal end of the balloon; d. a proximal guide wire seal disposed adjacent the proximal guide wire port; e. a distal guide wire port providing access from the exterior of the catheter into the interior of the catheter at a location distal of the distal end of the balloon; f. a distal guide wire seal disposed distal of the proximal end of the balloon; and g. a blood perfusion tube having a proximal end and a distal end, the proximal end of the perfusion tube connected to the distal end of the shaft at a location adjacent the proximal end of the balloon and the distal end of the perfusion tube connected to the distal end of the balloon.
Claim 2
Dependent Claim
207 words
A balloon dilation catheter having an interior and an exterior, the catheter comprising: a. an elongate shaft having a proximal end, a distal end, and an inflation lumen extending therethrough; b. an inflatable balloon connected to the distal end of the elongate shaft, the balloon having a proximal end, a distal end and an interior in fluid communication with the inflation lumen; c. a proximal guide wire port providing access from the exterior of the catheter into the interior of the catheter at a location proximal of the proximal end of the balloon; d. a proximal guide wire seal disposed adjacent the proximal guide wire port; e. a distal guide wire port providing access from the exterior of the catheter into the interior of the catheter at a location distal of the distal end of the balloon; f. a distal guide wire seal disposed distal of the proximal end of the balloon; and g. a blood perfusion tube having a proximal end and a distal end, the proximal end of the perfusion tube connected to the distal end of the shaft at a location adjacent the proximal end of the balloon and the distal end of the perfusion tube connected to the distal end of the balloon.
