Abstract
The disclosed device, systems and methods relate to a novel catheter, system and methods. Exemplary embodiments comprise a plurality of lumens and balloons for insertion into the aorta and vena cava. These catheters are for use in cardiopulmonary resuscitation and other medical or surgical conditions that require emergency restoration of cerebral and cardiac blood supply.
Claims
exact text as granted — not AI-modified1 . An aortic catheter comprising:
(a) a first elongate, substantially tubular primary aortic lumen having proximal and distal ends and comprising at least one aortic opening at the distal end; (b) at least one elongate substantially tubular supplemental aortic lumen constructed and arranged to extend substantially past the distal aortic opening; and (c) at least one aortic balloon in operational communication with the at least one supplemental aortic lumen so as to be inflated by way of the supplemental aortic lumen.
2 . The aortic catheter of claim 2 , further comprising a pressure sensor constructed and arranged to measure pressure in the aorta or inferior vena cava.
3 . The aortic catheter of claim 1 , further comprising a vena cava catheter constructed and arranged to be disposed within the vena cava of the patient and comprising:
(a) a first elongate, substantially tubular primary venous lumen having proximal and distal ends and comprising at least one venous opening at the distal end; (b) at least one elongate substantially tubular supplemental venous lumen constructed and arranged to extend substantially past the distal venous opening; and (c) at least one venous balloon in operational communication with the at least one supplemental venous lumen so as to be inflated by way of the supplemental venous lumen.
4 . The aortic catheter of claim 3 , further comprising a pressure sensor constructed and arranged to measure pressure in the aorta or inferior vena cava.
5 . The aortic catheter of claim 4 , wherein the pressure sensor is disposed on the catheter or on a control unit.
6 . The aortic catheter of claim 4 , wherein the aortic catheter is constructed and arranged for perfusing the heart of the patient via a control unit in operational communication with the catheters.
7 . The aortic catheter of claim 6 , wherein the control unit is constructed and arranged to provide blood in response to the measured pressure.
8 . The aortic catheter of claim 6 , wherein the inflation and deflation of at least one of the aortic balloon or the venous balloon can be controlled by the pressure sensor.
9 . A cardiopulmonary resuscitation catheter system for use in a patient to permit isolation of a portion of the vascular system of the patient, the system comprising:
(a) a resuscitation catheter comprising:
(i) an elongate catheter shaft defining a first elongate, substantially tubular primary lumen having proximal and distal ends and comprising at least one opening at the distal end; and
(ii) at least one balloon in operational communication with the elongate catheter shaft and constructed and arranged so as to be inflated; and
(b) a control unit comprising an air pump in hermetic communication with the at least one balloon, wherein:
(i) the elongate catheter shaft is constructed and arranged to be disposed within the vena cava of the patient, and
(ii) the control unit is constructed and arranged to control the inflation of the at least one balloon to a specified pressure.
10 . The system of claim 9 , further comprising at least one elongate substantially tubular supplemental lumen.
11 . The system of claim 10 , wherein the at least one elongate substantially tubular supplemental lumen is constructed and arranged to be disposed within the primary lumen.
12 . The system of claim 9 , wherein the at least one balloon is in operational communication with the at least one elongate substantially tubular supplemental lumen and inflated by way of the supplemental lumen.
13 . The system of claim 9 , wherein the at least one balloon comprises a circumferential balloon disposed outside the primary lumen and is constructed and arranged to be inflated in the descending aorta of the patient.
14 . The system of claim 13 , wherein the second balloon is constructed and arranged to be passed into the ventricular cavity of the patient and inflated.
15 . The system of claim 13 , wherein the control unit is constructed and arranged to inflate and deflate the first balloon and / or second balloon in response to changes in blood pressure.
16 . The catheter of claim 12 , further comprising at least one valve in operational communication with the at least one balloon and at least one supplemental lumen, wherein the at least one valve is constructed and arranged to allow passage of fluid or gas into the at least one balloon for inflation and deflation.
17 . The catheter of claim 12 , wherein the catheter is constructed and arranged to be disposed within the vena cava of the patient.
18 . A cardiopulmonary resuscitation system, comprising:
(a) an elongate, tubular catheter constructed and arranged to be inserted through the aortic valve of the patient comprising:
(i) an elongate primary lumen, comprising:
(A) a proximal primary lumen end;
(B) a distal primary lumen end; and
(C) at least one opening at the distal primary lumen end;
(ii) at least one elongate supplemental lumen disposed within the primary lumen, the supplemental lumen comprising:
(A) a proximal supplemental lumen end; and
(B) a distal supplemental lumen end;
(iii) a first balloon disposed outside the primary lumen and adapted for inflation; and
(iv) a second balloon in operational communication with the supplemental lumen; and
(b) an external control unit.
19 . The system of claim 18 , wherein the elongate, tubular catheter is constructed and arranged for:
(a) positioning the opening within the descending aorta of the patient; (b) inflating the first balloon within the descending aorta of the patient via the external control unit; and (c) inflating the second balloon distally of the right and left coronary arteries of the patient.
20 . The system of claim 19 , wherein the tubular catheter is further constructed and arranged for regulating the inflation of the first balloon and second balloon in response to changes in blood pressured measured by at least one pressure sensor.Join the waitlist — get patent alerts
