Week 4 Progress Report Project: Injection Catheter for stem cells Team: Adam Goon – Team Leader Joel Webb– Communications Andrew Bertram – BWIG Michael Conrardy – BSAC Week: September 25- September 1 Client: Tim Hacker Dept. of Medicine UW School of Medicine and Public Health Phone: 263-1539 email: [email protected] Advisor: Prof. John Webster 2148 Engineering Centers Building 1550 Engineering Drive Madison, WI 53706 Problem Statement Different methods are used to inject stem cells into the tissue of the heart after a heart attack has occurred. These methods include using an IV, injecting into the arteries that lead to the heart, and surgery to open the chest and inject directly into the heart. These methods are both ineffective for high percentage of stem cells reaching the desired tissue in the heart and are invasive. An improved method of using an injection catheter to inject stem cells is desired. Currently, an injector catheter is being used to run up the femoral artery to the heart where it enters through the aorta artery. Once in the chambers of the heart the catheter can extend a needle out the tip for injections. The purpose is for the needle to penetrate the heart and reach the outer layer of tissue. An injection of stem cells is then sent through the catheter and into the tissue of the heart. The whole procedure is taking too long of time and is very tedious to inject a wide area of the heart because of the adjustment required with one needle tip. A method is needed to improve precision and lessen the time to complete the procedure. This could be done by having multiple injections into the heart without adjusting the catheter. Also, a corkscrew needle could be implemented to make sure the needle is in the tissue and won’t come out when injecting the stem cells. Last Week’s Goals • Meet with client to discuss new injection catheter project • Determine if we are going to switch projects to injection catheterAccomplishments • Met with client and another doctor working on the catheters to discuss the new project • Decided to switch projects to the injection catheter project • Developed new problem statement related to new project • Conducted research on current injection catheters This Week’s Goals • Brainstorm new ideas how to make injection catheter with multiple injections • Create new draft of PDS • Research injection catheters and corkscrew needles • Work with client to adjust problem statement and talk with client about which direction to go on project Difficulties • Deciding if we are going to switch projects • Finding a time to meet with client that all members could attend Team Effort Team Member Accomplishments Time (Hrs) Adam Goon Individual research, team meeting, client meeting 2.5 Joel Webb Individual research, team meeting, client meeting 2.5 Andrew Bertram Individual research, team meeting 1.5 Mike Conrardy Individual research, team meeting 1.5Current Progress: Expenses to Date: • No expenses to report at this time.
